What is Web Hosting?

Web hosting is a service that allows organizations and individuals to post a website or web page onto the Internet. A web host, or web hosting service provider, is a business that provides the technologies and services needed for the website or webpage to be viewed on the Internet. Websites are hosted or stored, on special computers called servers. When Internet users want to view your website, all they need to do is type your website address or domain into their browser. Their computer will then connect to your server and your webpages will be delivered to them through the browser.

Types of Web Hosting

Shared hosting

This type of hosting is the most common answer for most web hosting needs and it’s an excellent solution for most small businesses and personal blogs. With this type of hosting, you’re sharing one server with other clients. Websites hosted on the same server share all their resources, such as memory, computing power, disk space, and others.

VPS hosting

When you’re using a Virtual Private Server or VPS for short you’re still sharing a server with other users. However, your web host allocates an entirely separate partition for you on that server. This means you get a dedicated server space and a reserved amount of resources and memory.

In fact, VPS hosting can be great for medium-sized businesses with a rapidly growing number of websites and traffic.

Cloud hosting

Cloud hosting is currently the most reliable solution on the market. With cloud hosting, your host provides you with a cluster of servers your files and resources are replicated on each server.

When one of the cloud servers are busy or encounter a problem, your traffic is automatically routed to another server in the cluster. This results in little to no downtime, which is excellent if you own a very busy website.

Word Press hosting

Word Press hosting is a particular form of shared hosting, created for Word Press site owners. Your server is configured specifically for Word Press and your site comes with pre-installed plugins for crucial tasks, such as caching and security.

Because of the highly optimized configuration, your site loads much faster and runs with fewer problems. Word Press hosting plans frequently include additional Word Press-related features, such as pre-designed Word Press themes, drag-and-drop page builders, and specific developer tools.

Dedicated hosting

Dedicated hosting means that you have your own physical server that’s dedicated solely to your website. Therefore, you’re given incredible flexibility over how you want to manage your website. You can configure your server as you wish, choose the operating system and software you want to use, and set up the whole hosting environment according to your own needs.

In fact, renting a dedicated server is just as powerful as owning your own on-site server, but comes with the professional support of your web host. Usually, this is more oriented towards large online businesses that deal with heavy traffic.

Top 10 Incredibly microscopic creatures

2021-03-16T02:49:00.002-07:00

Nature is an incredible place that has a lot of mysterious things. Actually, it is very difficult to understand. To tell the truth, all of us are children of us. She gave birth to us so we have a responsibility to protest her.

Nature is in a very high stage than us. She made us so she can destroy us very easily. But some people think they are the greatest, they didn’t think about nature. They also think their creations and invents are the greatest. Others also think those are the greatest things but it is a wrong idea. If you can compare those things with natural creatures, you can simply identify your fault.

Natural creatures are greater than all other artificial things. Not only visible creatures but also invisible creatures are too complex for humans to comprehend. In that article, you can find out about incredibly Intricate Microscopic Organisms. I think they can Blow Your Mind out.

Top 10 Incredibly
microscopic creatures

Coccolithophores

A coccolithophore is unicellular, eukaryotic phytoplankton(alga). They belong either to the kingdom Protista. The coccolithophorids are in the phylum or division Haptophyta, class Prymnesiophyceae. Coccolithophorids are distinguished by special calcium carbonate plates (or scales) of an uncertain function called coccoliths, which are also important microfossils. This semi-organic structure is one of many kinds produced by single-celled algae called coccolithophores. Braarudosphaera Bigelow, the pentagonal species pictured above, is perfectly formed, almost as though it was factory-made. Twelve will cleave together to form a seamless dodecahedron about five microns in size.

Coccolithophores are spherical cells about 5–100 micrometers across, enclosed by calcareous plates called coccoliths, which are about 2–25 micrometers across. Each cell contains two brown chloroplasts which surround the nucleus.

Coccolithophores produce monoliths in a variety of shapes. Most demonstrate unusual structural strength thanks to a series of interlocking crystals that support each face.

Coccolithophores are almost exclusively marine and are found in large numbers throughout the sunlight zone of the ocean. It is studied for the extensive blooms it forms in nutrient-depleted waters after the reformation of the summer thermocline and for its production of molecules known as alkenones that are commonly used by earth scientists as a means to estimate past sea surface temperatures. Coccolithophores are of particular interest to those studying global climate change because as ocean acidity increases, their coccoliths may become even more important as a carbon sink.

Rotifers

The rotifers are commonly called wheel animals or wheel animalcules. make up a phylum of microscopic and near-microscopic pseudo coelomate animals. Rotifers, sometimes called “wheel animals,” are common microorganisms famous for their bizarre mouthparts. In front, two rings of cilia beat in synchronized motions to sweep food into the mouth. Behind these rotary organs lies a set of bony, highly articulated jaws.

They were first described by Rev. John Harris in 1696, and other forms were described by Antonie van Leeuwenhoek in 1703. Most rotifers are around 0.1–0.5 mm long (although their size can range from 50 μm to over 2 mm) and are common in freshwater environments throughout the world with few saltwater species. Some rotifers are free-swimming and truly planktonic, others move by inch worming along a substrate, and some are sessile, living inside tubes or gelatinous holdfasts that are attached to a substrate.

Rotifers are an important part of the freshwater zooplankton, being a major food source and with many species also contributing to the decomposition of soil organic matter.

A rotifer’s jaws are just as intricate. As zoologist Dr. Ross Piper puts it, “For an animal so small and with only around 1,000 cells in its entire body, this structure is amazingly complex; an assemblage of muscles, ligaments, and toothed plates all working together to macerate the food before it’s digested.”

Loriciferans

Loricifera is a phylum of very small to microscopic marine cycloneuralian sediment-dwelling animals with 37 described species, in nine genera. there are approximately 100 more that have been collected and not yet described. Their sizes range from 100 μm to ca. 1 mm.

Referred to as “masters of miniaturization,” loriciferans are multicellular animals the size of most single-celled ones. A set of about 10,000 specialized cells allows them to have a disproportionately complex body.

Sensory spines called scales blossom like a bouquet from its vase-shaped body. At the center of this spiny crown is a mouth-cone that unfolds and emerges from the abdomen like a telescope.

The newly reported animals complete their life cycle in the total absence of light and oxygen, and they are less than a millimeter in size. They were collected from a deep basin at the bottom of the Mediterranean Sea, where they inhabit a nearly salt-saturated brine that, because of its density (> 1.2 g/cm³), does not mix with the waters above. As a consequence, this environment is completely anoxic and, due to the activity of sulfate reducers, contains sulphide at a concentration of 2.9 mM. Despite such harsh conditions, this anoxic and sulphidic environment is teeming with microbial life, both chemosynthetic prokaryotes that are primary producers, and a broad diversity of eukaryotic heterotrophs at the next trophic level.

Foraminifera (Forams)

Foraminifera is single-celled organisms, members of a phylum or class of amoeboid protists characterized by streaming granular ectoplasm for catching food and other uses; and commonly an external shell (called a "test") of diverse forms and materials.

These shells are commonly made of calcium carbonate (CaCO3) or agglutinated

sediment particles. Over 50,000 species are recognized, both living (10,000) and fossil (40,000). They are usually less than 1 mm in size, but some are much larger, the largest species reaching up to 20 cm.

These tests are miniature superstructures. Despite being less than 1 millimeter (.04 in) in size, a foram’s test can be as simple as a few fused spheres or cathedral-like, with countless winding chambers and arches hidden within.

Forams also grow pseudopodia, which are temporary fibrous growths seen in other unicellular protists. Forams, however, will combine their pseudopodia into living nets that capture their prey. The growths making up the nets are hollow and can act as a rudimentary circulatory system.

Osperalycus tenerphagus

In 2014, entomologist Samuel Bolton discovered a bizarre new species of mite outside the main campus of Ohio State University. Described as both “dragon-like” and “worm-like,” it was strange enough to warrant the creation of a whole new genus.

It lives in the space between particles in sandy, impoverished soils. Despite its dragon-like appearance, Osperalycus tenerphagus is a vulnerable creature and, out of necessity, a recluse.

“These mites are seldom found in soil with high organic content. This is probably because more things live there, including competitors and predators,” says Samuel Bolton, the entomologist who discovered the mite. They do better in adverse habitats where there are few other organisms, even others of their kind. Because these mites abstain from sex, “there is no reason for them to look for mates,” Bolton says

The mite’s long, soft body is covered in exquisite arrays of interlocking ridges and scales. The evolutionary history behind its unique way of moving is still a mystery. Using hydraulic pressure, its body stretches and contracts in an accordion-like motion to maneuver through microscopic gaps.

Enterobacteria Phage T4

Escherichia virus T4 is a species of bacteriophages that infect Escherichia coli bacteria. It is a double-stranded DNA virus in the subfamily Tevenvirinae from the family Myoviridae. T4 is capable of undergoing only a lytic lifecycle and not the lysogenic lifecycle. The species was formerly named T-even bacteriophage, a name which also encompasses, among other strains (or isolates), Enterobacteria phage T2, Enterobacteria phage T4, and Enterobacteria phage T6.

The specific time and place of T4 virus isolation remain unclear, though they were likely found in sewage or fecal material. T4 and similar viruses were described in a paper by Thomas F. Anderson, Max Delbrück, and Milislav Demerec in November 1944.

The complete genome sequence of phage T4 contains 168,903 base pairs and encodes about 300 gene products. These virulent viruses have played a key role in the development of virology and molecular biology.

Phage T4 is a type of virus that has provided us with a wealth of information on genetics. It synthesizes some of the most complex particles seen in molecular biology and has become a sort of celebrity specimen due to its instantly recognizable structure.

The T4 is distinctly mechanical and bears a striking resemblance to NASA’s moon landing modules. Its “head,” a polyhedron with 20 faces, is carried atop a long rod that is structurally similar to the pipeline of an oil rig.

Dinoflagellates

The dinoflagellates are single-celled eukaryotes constituting the phylum Dinoflagellata. Usually considered algae, dinoflagellates are mostly marine plankton, but they also are common in freshwater habitats. Their populations are distributed depending on sea surface temperature, salinity, or depth. Many dinoflagellates are known to be photosynthetic, but a large fraction of these are in fact mixotrophic, combining photosynthesis with ingestion of prey.

To be specific, one dinoflagellate nucleus can contain as much as 250 picograms (pg) of DNA per cell. A human nucleus contains a mere 3.2 pg. Stranger still, some dinoflagellate species have nuclei that are triangular, tetragonal, kidney-shaped, or U-shaped.

Dinoflagellates are one of the largest groups of marine eukaryotes, although this group is substantially smaller than diatoms. Some species are endosymbionts of marine animals and play an important part in the biology of coral reefs. Other dinoflagellates are unpigmented predators on other protozoa, and a few forms are parasitic. Some dinoflagellates produce resting stages, called dinoflagellate cysts or dinocysts, as part of their lifecycles, and are known from 84 of the 350 described freshwater species, and from a little more than 10% of the known marine species. Dinoflagellates are alveolates possessing two flagella, the ancestral condition of bikonts.

Copepods

Copepods are a group of small crustaceans found in nearly every freshwater and saltwater habitat. Some species are planktonic (inhabiting sea waters), some are benthic (living on the ocean floor), a number of species have parasitic phases, and some continental species may live in limnoterrestrial habitats and other wet terrestrial places, such as swamps, under leaf fall in wet forests, bogs, springs, ephemeral ponds, and puddles, damp moss, or water-filled recesses (phytotelmata) of plants such as bromeliads and pitcher plants. Many live undergrounds in marine and freshwater caves, sinkholes, or stream beds. Copepods are sometimes used as biodiversity indicators.

These crustaceans are so tiny that they can simply absorb oxygen. They have no need for a heart or circulatory system. Yet they have a remarkably well-organized, myelin-based nervous system, a trait previously thought to be exclusive to invertebrates.

Their specialized neural pathways give them acrobatic abilities that aren’t seen anywhere else in the animal kingdom. Proportionally speaking, the copepod is technically the world’s fastest and strongest animal. At less than 1 millimeter (.04 in) in size, they are capable of traveling 0.5 meters (1.6 ft) per second, within a few thousandths of a second. This is a feat of mechanical efficiency not yet achieved by any man-made motor.

Planktonic copepods are important to global ecology and the carbon cycle. They are usually the dominant members of the zooplankton and are major food organisms for small fish such as the dragonet, banded killifish, Alaska pollock, and other crustaceans such as krill in the ocean and in freshwater. Some scientists say they form the largest animal biomass on earth.

Diatoms

Diatoms are a major group of algae, specifically microalgae, found in the oceans, waterways, and soils of the world. Living diatoms make up a significant portion of the Earth's biomass: they generate about 20 to 50 percent of the oxygen produced on the planet each year, take in over 6.7 billion metric tons of silicon each year from the waters in which they live, and constitute nearly half of the organic material found in the oceans.

Diatoms also have a robust urea cycle, which is otherwise unique to animals. This feature allows them to make use of carbon and nitrogen more efficiently and may explain why diatoms exist in such huge numbers today.

Diatoms are unicellular: they occur either as solitary cells or in colonies, which can take the shape of ribbons, fans, zigzags, or stars. Individual cells range in size from 2 to 200 micrometers. In the presence of adequate nutrients and sunlight, an assemblage of living diatoms doubles approximately every 24 hours by asexual multiple fission; the maximum life span of individual cells is about six days.

They have only 6 days to live. We have a lifespan of approximately 60-70 years. If we lose what they do for us in 6 days, we will not live as long as they do.

Radiolarians

The Radiolaria, also called Radiozoa, are protozoa of diameter 0.1–0.2 mm that produce intricate mineral skeletons, typically with a central capsule dividing the cell into the inner and outer portions of endoplasm and ectoplasm. The elaborate mineral skeleton is usually made of silica. Radiolarians of this kind have existed for at least 600 million years, and slightly simpler variants existed long before then.

They are found as zooplankton throughout the global ocean. As zooplankton, radiolarians are primarily heterotrophic, but many have photosynthetic endosymbionts and are, therefore, considered mixotrophs. The skeletal remains of some types of radiolarians make up a large part of the cover of the ocean floor as siliceous ooze. Due to their rapid change as species and intricate skeletons, radiolarians represent an important diagnostic fossil found from the Cambrian onwards.

Those Microscopic Organisms are incredible definitely as well as they do a lot of things for us but we don't know about that. actually, we should thank them for those things. If they stop their work, that will be the end of us.

Top 10 Places On Earth With Unsolved Mysteries

2021-03-09T03:12:00.002-08:00

The universe is an amazing place. It has lots of mysterious things since its beginning. Actually, we haven’t a clear idea about the beginning of the universe but lots of scientists accept the Big Bang theory. The Big Bang was the moment 13.8 billion years ago when the universe began as a tiny, dense, fireball that exploded. According to that theory, there are neither planets nor living things before the big bang. After that big bang, planets formed and then gradually came into living things.

13.8 billion years later, one thing has existed ever since. It is the mystery of the universe. We couldn’t solve those things until now but people are sorry for that. Because the universe is a huge and amazing place that we can’t understand. It hasn’t measurable height, width, or depth.

Earth is a very small part compares with the universe but we don’t know a lot of things about our world. Some places people haven’t even seen yet but some places are very famous. People aren’t sorry for that. Now you can study 10 places among them. You may have seen some places but the mystery of those places is still unsolved. Do you know those mysteries?

Bermuda Triangle

Bermuda Triangle is a very famous mysterious place. Some call it the Devil's Triangle. It covers around 500 000 square miles of the Atlantic Ocean between Miami in Florida, San Juan in Puerto Rico, and the island of Bermuda where dozens of ships and airplanes have disappeared. There are lots of mysteries about the Devil's Triangle. It has a long history.

The Bermuda triangle legend begins in 1492, on the night of October 11. Christopher Columbus reportedly saw an unknown light falling into the sea during his first voyage, shortly before landing in Guanahani.
William Shakespeare’s play “The Tempest,” which some scholars claim was based on a real-life Bermuda shipwreck, may have enhanced the area’s aura of mystery
In March 1918, the USS Cyclops, a 542-foot-long Navy cargo ship with over 300 men and 10,000 tons of manganese ore onboard, sank somewhere between Barbados and the Chesapeake Bay. The Cyclops never sent out an SOS distress call despite being equipped to do so, and an extensive search found no wreckage.
In 1941 two of the Cyclops’ sister ships similarly vanished without a trace along nearly the same route.
Flight 19 was a training flight of five TBM Avenger torpedo bombers that disappeared on December 5, 1945, while over the Atlantic. The squadron's flight plan was scheduled to take them due east from Fort Lauderdale but the flight never returned to base.
G-AHNP Star Tiger disappeared on January 30, 1948, on a flight from the Azores to Bermuda
G-AGRE Star Ariel disappeared on January 17, 1949, on a flight from Bermuda to Kingston, Jamaica.
On August 28, 1963, a pair of US Air Force KC-135 Stratotanker aircraft collided and crashed into the Atlantic 300 miles west of Bermuda

The authors tried to explain by using aliens, Atlantis, and sea monsters, and reverse gravity fields, whereas more scientifically minded theorists have pointed to magnetic anomalies, waterspouts, or huge eruptions of methane gas from the ocean floor. In all probability, however, there is no single theory that solves the mystery.

The Nazca Lines in Peru

The Nazca Lines is another very famous mysterious place. The Nazca Lines are a group of very large geoglyphs made in the soil of the Nazca Desert in southern Peru. They were created between 500 BCE and 500 CE by people. Peru dessert depicts various shapes, including 70 identifiable animals and plants. These images can only be seen properly from above. The lines are massive, some measuring over a kilometer. Scientists studied for over 80 years then they were designated a UNESCO World Heritage Site in 1994.

What can you see there?

There are more than 800 straight lines on the coastal plain, some of which are 30 miles (48 km) long.
There are over 300 geometric designs, which include basic shapes such as triangles, rectangles, and trapezoids, as well as spirals, arrows, zig-zags, and wavy lines.
It is best known for the representations of about 70 animals and plants, some of which measure up to 1,200 feet (370 meters) long.
spider, hummingbird, cactus plant, monkey, whale, llama, duck, flower, tree, lizard, and dog are some of the animals.

The desert floor is covered in a layer of iron oxide-coated pebbles of a deep rust color. The ancient peoples created their designs by removing the top 12 to 15 inches of rock, revealing the lighter-colored sand below. More recent research suggested that the Nazca Lines’ purpose was related to water. The geoglyphs weren’t used as an irrigation system or a guide to find water but rather as part of a ritual to the gods to bring much-needed rain. All things are suggestions but those geoglyphs are still a mystery to researchers.

Hidden people and Elves in Iceland

Iceland, just like other Nordic countries, is known for its strong folk belief. There are many sagas and tales which describe Hidden people, Elves, and Other mythological creatures such as monsters, serpents, wurms, chimeras, nuggles, and more. ). These mysterious creatures are thought to be hardly visible for humans; hidden in rocks, hills, and lava fields. They look and behave similarly to humans, but live in a parallel world.

Hidden People are the human size and look and behave like humans. However, they are invisible to humans and live in wild nature. They are eternal and immortal. The difference between the Hidden People and Elves is uncertain and there may be none at all. Traditional folklore and ancient fairy tales do not make a clear distinction. Often Elves are smaller, but even the size is not a clear guideline. Hidden People, however, often seem to have more and closer interactions with humans than (other) Elves. Numerous stories recount how they frequently overstep or transcend the invisible border between the sphere of the human and ethereal race. They mingle and mess with people, for better or worse.

So Many Icelanders Still Believe in Invisible Elves. In one 1998 survey, 54.4 percent of Icelanders said they believed in the existence of elves. In addition to that, according to an academic paper published in 2000 titled “The Elves’ Point of View" by Valdimar Hafstein, who now is a folkloristics professor at the University of Iceland. “If this was just one crazy lady talking about invisible friends, it's really easy to laugh about that,” Jónsdóttir said. “But to have people through hundreds of years talking about the same things, it’s beyond one or two crazy ladies. It is part of the nation.” I agree 100% with him because it became a part of their culture.

A 2006 survey found that "54% of respondents did not distinguish between elves and hidden people, 20% did and 26% said they were not sure. That is the situation now in Iceland but I have an unclear point. If it is the only folk tale, Why 20% of people believe that until then. Peoples are very educated and smart now so they can easily tell if it is a folk tale or not.

The Eternal Flame in New York

New York is home to one of the most curious unsolved mysteries. The Eternal Flame in New York is a special place among them. Fire and water may be opposing elements. Did you see fire and water in one place at one time without fighting? but here these two forces create a magical spectacle. If you need to see the friendship between water and fire, you should go to the Eternal Flame.

The Eternal Flame Falls is a small waterfall located in the Shale Creek Preserve, a section of Chestnut Ridge Park in Western New York. Its total height is only 30 feet. A small grotto at the foot of the waterfall emits natural gas. Geologists from Indiana University Bloomington and Italy's National Institute of Geophysics and Volcanology studied Eternal Flame Falls in 2013. They found that the 'macro seep' at Eternal Flame Falls had higher concentrations of ethane and propane (about 35%) than other known natural gas seeps, which typically contain a greater proportion of methane. They estimated that the seep at the falls emits approximately one kilogram of methane per day.

It isn't enough to explain that situation. Typically, shale must be hot (around 100 °C) for its carbon structures to break down and form smaller natural gas molecules. However, the shale from which Eternal Flame Falls draws its gas is much cooler, in addition to being younger and shallower than typical gas-bearing shale. This may indicate that additional, as yet undemonstrated, processes can contribute to the creation of natural gas in shale; one possibility is that a catalyst capable of breaking down shale in cooler conditions is present.

The Crooked Forest of Poland

You can see crooked people around the world but you can't see the crooked forests except in Poland. If you need to see the crooked forest, you should go to the town of Gryfino, West Pomerania, Poland.

This groovy grove of trees is a weird wonderland of some 400 pines that took a definite detour in the ol’ “growing straight as a tree” routine. This grove of pines was planted in the village of Nowe Czarnowo around the 1930s and whatever caused them to waver in their sky-striving happened when they were seven to 10 years old. Each pine tree bends sharply to the north, just above ground level, then curves back upright after a sideways excursion of three to nine feet (1–3 m). The curved pines are enclosed by a surrounding forest of straight pine trees.

There are many theories on the mystery.

Some hypothesize that a unique gravitational pull in this particular area caused the trees to grow curved northwards.
Others guess that the heavy snowfall in the area weighed down the trees as they were sprouting, causing them to grow crookedly at the base.
Some suspect that the trees were grown for the rims of wooden cartwheels as the grain direction would have produced very tough wheels.
The most widespread and most likely explanation is that local farmers planted and manipulated the trees when they planted them in 1930.

All of these theories are guesses only. A lot of guesses haven't even a scientific base. In conclusion, I can say one thing people can say anything and they also can guess some things but until trees can talk, we may never know the real story.

Uluru in Australia

The huge red rock of Uluru is one of Australia’s most iconic attractions. Uluru is known as Ayers Rock. Uluru is a large sandstone rock formation in the southern part of the Northern Territory in Australia. It lies 335 km southwest of the nearest large town, Alice Springs. It rises dramatically from the Central Australian desert. Its origins date back to around 600 million years, just as old as the Australian continent itself. Historically, 46 species of native mammals are known to have been living near Uluru. Furthermore, Uluru is a UNESCO World Heritage since 1987.

Uluru has been a popular destination for tourists since the late 1930s. Uluru was first mapped by Europeans in 1872 during the expeditionary period made possible by the construction of the Australian Overland Telegraph Line. In separate expeditions, Ernest Giles and William Gosse were the first European explorers to this area. While exploring the area in 1872, Gosse observed Uluru and named it Ayers' Rock, in honor of the Chief Secretary of South Australia, Sir Henry Ayers.

This rock has an unsolved mystery thing. That mystery is how Uluru changes colour depending on the position of the sun. It is a huge red stone that turns into a magical vibrant pink as the sun rises, shades of amber during noon, and yellow ochre as the sunsets.

In addition to that thing the old traditions of the Australian Aborigines believe it’s one of the last remaining homes of the creator beings who forged the earth. Meanwhile, other folks come here to energise themselves at the fluvial channels that run underneath the rock. What is the meaning of those things?

Easter Island in Polynesia

Easter Island is a mysterious and famous island and special territory of Chile in the southeastern Pacific Ocean, at the southeasternmost point of the Polynesian Triangle in Oceania. Estimated dates of early settlement on Easter Island are c. 300 to 1200 but the name "Easter Island" was given by the island's first recorded European visitor, the Dutch explorer Jacob Roggeveen, who encountered it on Easter Sunday (5 April) in 1722, The island is most famous for its nearly 1,000 extant monumental statues, called moai, which were created by the early Rapa Nui people. That island is a UNESCO World Heritage since 1995, with much of the island protected within Rapa Nui National Park.

When you first see a Moai statue you are drawn to its disproportionately large head (compared to body length) and that is why they are commonly called “Easter Island Heads”. But once you appreciate the size and scale of these massive stone sculptures you begin to wonder; Who put them here? What purpose do they have? How did they transport them across? That is the mystery behind these statuses.

Archaeologists suggest that the statues were a representation of the Polynesian people’s ancestors. The Moai statues face away from the sea and towards the villages, by way of watching over the people. So here at Ahu Tongariki, these Moai look over a flat village site but this suggestion has a hole. The hole is that some Moai faces are against it. In conclusion, I can say one thing this island has a mystery but I don't know who will solve that? Maybe it will remain a mystery.

Lake Natron in Tanzania

Lake Natron is an amazing and dangerous creature of nature. It situated in northern Tanzania on the border with Kenya, lying in the East African Rift System, 70 miles (113 km) northwest of Arusha. The lake is fed principally by the Southern Ewaso Ng'iro River, which rises in central Kenya, and by mineral-rich hot springs. It has a 3-meter depth, a maximum of 57 kilometers length, and 22 kilometers width.

This lake is more special than other lakes because It can do something amazing that no other lake can. This lake has mummification mastery. The alkalinity of the lake can reach a pH of greater than 12. so it can burn the skin and eyes of animals that aren't adapted to it. The water's alkalinity comes from the sodium carbonate and other minerals that flow into the lake from the surrounding hills. And deposits of sodium carbonate which was once used in Egyptian mummification and it also acts as a fantastic type of preservative for those animals unlucky enough to die in the waters of Lake Natron.

On the other hand, Lake Natron's alkaline waters support a thriving ecosystem of salt marshes, freshwater wetlands, flamingos and other wetland birds, tilapia, and the algae on which large flocks of flamingos feed.

Nick Brandt who is the writer of "Across the Ravaged Land" said "I unexpectedly found the creatures — all manner of birds and bats — washed up along the shoreline of Lake Natron," Brandt wrote in his book. "No one knows for certain exactly how they die, but … the water has an extremely high soda and salt content, so high that it would strip the ink off my Kodak film boxes within a few seconds."

This lake supports some beings but It kills some living things. What is the reason for it? That is the mystery.

Devil's Kettle Falls

Devil's Kettle is another famous and unsolved mystery place in the world. It is situated in Judge C. R. Magney State Park in the U.S. state of Minnesota, on the North Shore of Lake Superior. The park is best known for the Devil's Kettle, an unusual waterfall and rock formation in which half of the Brule River disappears into a pothole.

The Devil's Kettle waterfall is located on the Brule River 2.4 km from its mouth. The river splits in two to flow around a mass of rhyolite rock. The eastern flow goes over a two-step 15 m waterfall and continues downstream. The western flow surges into a pothole, falling at least 3.0 m from where it was popularly understood to "disappear underground."

For years, people have tried to figure out where that water goes. Logs and Ping-Pong balls tossed into the churning cauldron seemed to simply vanish, fueling speculation that the lost branch of the river might flow for miles underground, carrying bobbing debris down to the distant shores of Lake Superior or off to some underground cavern.

In February 2017, the Minnesota Department of Natural Resources said that water that disappears into the rock at Devil's Kettle resurges in the stream below the waterfall. Hydrologists compared the amount of water flowing above the waterfall with the amount flowing below it to see if some water was lost somewhere between the two locations.

Green and a team of DNR hydrologists used stream gauging equipment to measure the volume of water flowing above the falls and below. hydrologists measured water flow above Devil's Kettle at 123 cubic feet per second, while several hundred feet below the waterfall, the water was flowing at 121 cubic feet per second.

In the world of stream gauging, Green explained, those readings are nearly identical. The river didn’t go anywhere.

So if the river didn’t stray far, why didn’t the Ping-Pong balls and other debris resurface downriver? That is the question.

Sigiriya in Sri Lanka

Sigiriya is the most famous and iconic place in sri lanka.The 600 foot high rock sits in the Matale District but the ruins of the royal palace are what make it unique. This site was selected by King Kashyapa (477 – 495 CE) for his new capital. It has a long history at least five thousand years It is still a sight to behold with the water gardens, rock gardens, cobra hood frescoes, mirrored wall, lion’s gate, and the remains of the palace at the summit. If you see this fascinating place, you will astonise definitely because it is a so amazing place to see. Sigiriya is a UNESCO World Heritage since 1982.

Water gardens of sigiriya are incredible. Arthur C Clarke drew inspiration from Sigiriya for his book, Fountains of Paradise. Even in their partially restored state, they were magnificent. Pools extended to the left and right of the main walkway leading to Sigiriya Rock. On the right, the pools have been fully excavated while on the left, they remained buried under the jungle soil. Pool after pool, they extend in beautiful symmetry which is an amazing level of urban planning for the time. There are also fountains that still flow during the rainy season that are fed by underground pipes from the cisterns further up the hill.

These underground water pipes still work but anyone don't know about its architecture. It is the major mystery of sigiriya. In addition to that the way water is pumped from the bottom to the top of the rock, the pool which doesn't dry out even during prolonged droughts and the sewage system that only wastewater are other mysteries. 5th century AD urban planning and landscaping, Engineering, Architecture, Arts and crafts and literature are also fascinating and amazing.

Top 10 Multi-Tasking Operating Systems 2021

2021-03-04T03:49:00.006-08:00

In ancient time people were in low-efficiency level but technological evolution changed that issue. Computer act the main role of that change. It could do lots of things correctly and quickly so it became an essential thing for people.

Computer has three parts mainly. They are Hardware, Software, and Firmware. Computer Hardware is the physical components that a computer system requires to function. It encompasses everything with a circuit board that operates within a PC or laptop; including the motherboard, graphics card, CPU (Central Processing Unit), power supply, and so on. Firmware is a specific class of computer software that provides low-level control for a device's specific hardware but without firmware, the most basic of devices would not function. That is why it is often stored on a Read-Only Memory (ROM) chip, ensuring it does not get erased by accident, all while remaining as close as possible to the metal of the device.
Software is a program that enables a computer to perform a specific task, as opposed to the physical components of the system (hardware).

In this article I consider about Operating Systems only because it is the main software part of the computer.

What is an Operating System?

An operating system in its most general definition is the software that allows a user to run crucial applications on his/her computing device. It helps to manage computer hardware, software resources and provides common services for computer programs. It helps to support basic functions like scheduling tasks, and controlling peripherals. In addition to that Operating System controls all input and output devices and it needs to install other software.

There are lots of operating systems but we can include all operating systems into 4 categories.

Single-user operating systems(One time- One user)
Example: MS-Dos Operating System
Multi-User Operating Systems(One time- multi-users)
This type of operating system mainly uses for mainframe computers.
Example: Linux. Windows server
Multi-Tasking operating systems(one time- One user but a lot of works)
Example: Windows 8, Windows 10, Ubuntu, Mac os
Real-time Operating Systems(Quick response)
This type of operating system mainly uses for Automatic machines and scientific equipment.
Example: ATM, calculators

Top 10 Multi-Tasking Operating Systems

Top 10 COVID-19 Vaccines

2021-02-26T08:12:00.020-08:00

VACCINES AND IMMUNIZATION

Part-02

This is the second part of my vaccine and immunization series. In part one, there will be lots of things about vaccines and immunization. If you didn't read it, please read it first.
https://mynettop10.blogspot.com/2021/02/vaccines-and-immunization-what-is.html

In this part, I am going to explain covid 19 vaccines. This is the covid 19 pandemic season so we should have a lite idea about the covid 19 vaccine. Sometimes you already vaccinate but this will be important to both vaccinate and non.

Who is involved in the covid-19
vaccine development?

The vaccine is a successful result of a huge sector, including private pharmaceutical firms teaming up with public health agencies or university labs. We can't explain all of them so some major characters are described here.
The United State aimed at developing an effective vaccine and manufacturing enough doses for all three hundred million Americans. Department of Health and Human Services, the National Institutes of Health (NIH), and the Food and Drug Administration (FDA), and the Department of Defense also join with that.
The European Union, world leaders, organizations, and banks pledged $8 billion for vaccine research.
In China, the government closely monitors land efforts, and state-owned companies such as Sinofarm make up about two-fifths of the country's vaccine industry.
The World Health Organization (WHO) and other multilateral institutions such as the World Bank are focused on financing and manufacturing COVID-19 vaccines for global use.
Norway and India also invest to develop covid vaccines.
The Bill & Melinda Gates Foundation, the UK-based Wellcome Trust, and the World Economic Forum are other major characters.
Many of the COVID-19 vaccine candidates have involved a university or college assisting in preclinical research or clinical trials.
The University of Oxford’s candidate, the research team to develop a covid vaccine.
The Gates Foundation has been the leading nonprofit funding COVID-19 vaccine efforts.

Who are the leading COVID-19

vaccine developers?

Scientists were tried to develop a covid 19 vaccine until December 2019 but, it wasn't an easy target. China, Russia, and the United States are mainly involved to achieve this target.

Pfizer and BioNTech Announced the world's-first high efficient Vaccine in November 2020. The first to receive emergency validation from WHO.
The first human trial in the United States began in March 2020 by Moderna Inc.
UK’s University of Oxford and British-Swedish company AstraZeneca is released cheaper and easier to store and transport than other vaccines.
Beijing has approved four of its candidates, several of which are being used by other nations.
Russia's has released the Sputnik V vaccine and Vector Institute's vaccine
Merck is engaged in research efforts for both the development of medicines and a vaccine for Covid-19.
Johnson & Johnson company entered several smart collaborations with Biomedical Advanced Research and Development Authority (BARDA), Beth Israel Deaconess Medical Center (BIDMC), and Emergent BioSolutions, Inc. to develop a vaccine and enter the U.S. market as the next vaccine.

In addition to those vaccines, EpiVacCorona is a Russian vaccine that is manufactured by Siberia’s Vector Institute, in November.

“According to results of the first and second phases of clinical trials, the immunological effectiveness of the EpiVacCorona vaccine is 100%.”

It was only used in Russia so that result would be changed in another country so I didn’t include it for my top 10. Sometimes it can be a perfect vaccine.

Can vaccines end the

pandemic?

Vaccination is the main treatment against the pandemic. There are lots of vaccines that are already manufactured. Other vaccines will come near future. So we can control this pandemic soon. But it won't an easy target. This is a world pandemic. Our world has a huge population amount. There are lots of vaccines need to vaccinate people around the world. Brazil, China, and India all have large vaccine industries but those facilities aren't enough to manufacture vaccines for the whole world.

On the other hand, wealthy countries including Australia, Canada, and the United States have struck deals with manufacturers to provide their countries with more than enough doses for their populations but lower-income countries unable to fulfill their requirements. ( They can use the COVAX facility but it has a limit )

Meanwhile, several new strains of the coronavirus are raising concerns among scientists and health officials about increased transmission, waning immunity in people already infected with COVID-19, and reduced effectiveness of vaccines that have already been developed.

According to those things, Vaccines can't end this pandemic within one month or two months but they will do it soon definitely. You have a major part of it. If you can spend your daily life, following health rules and regulations, We can eliminate this pandemic soon.

PART-2

This is the second part of the world in the future article series. If you didn't read the first part, please read that article before reading this one.

Super 3D Printing

You can say that 3D printing is old technology and it already uses. But at the end of that explanation, you will understand the fault of that idea. We already use 3D printing to make some vehicle parts, artworks, toys, Pc and mobile phone parts and etc. But this isn’t the depth, this is a small beginning only. In the future, you can see a lot of incredible things that you can’t believe. Super 3D printing will be the biggest thing that you can see in the nearest future. To tell the truth you will live in a 3D printed world in the future.

3D printing can do a lot of things. It will use for every field in the future. As an example, One day in the future you need to buy some clothes so you call for a taxi. After the taxi comes, you can get on to it. You shouldn’t be surprised that this is a 3D printed taxi. Then you can go to the shopping center. Maybe it’s a 3D printed building too, but don’t be surprised. Now you can buy 3D-printed clothes. Among the people, you meet your old friend. It‘s a simple and normal thing but the surprise is that. While the chat she says, ‘I had heart transplant surgery last month.’ Then you say, ‘Oh! How can you find a suitable heart?’ Then she says, ‘It is 3D printed one’. That’s the reality in the future.

How impact 3D printing on our lives?

Automobile industry- 3D printing will involve the design, development, and manufacturing of motor vehicles. To tell the truth automobile industry will be another part of 3D printing. They call as fully 3D printed vehicles. Not only that the potential of metal-based 3D printing allows the creation of rare suspended replacement parts in a variety of applications. Repair shops can handle a wider range of customers, and online retailers can print unique parts, providing more products with up-to-date product inventory access.

Construction industry- As well as the automobile industry 3D printing will involve the design, development, and manufacturing of buildings. Now you can see a lot of peoples on work sites but in the future, it will be totally different. 3D printers will construct buildings. People need to monitor those things only. Not only that 3D printers will repair all broken and old buildings.3D printing is being used to lower costs for companies so they can offer products at lower costs.
Banking- 3D printing shows promise to prevent card fraud, such as point-of-sale systems and ATMs. For example, banks now use 3D printing to design and manufacture automated ATM components that prevent credit card shortages. As the digital and physical security worlds meet, 3D printing will play an important role in creating hardware to combat fraud.
Medicine And Healthcare Applications- 3D printing will connect highly with this field. Lots of medicines will make by 3D printers. It will be a huge help for doctors when they treat incurable patients. Furthermore, hospitals can be their essential things. Such as gloves, masks, and other operating equipment. In addition to that 3D printed organs will be the major advantage for this so this technology will certainly improve the lives of many people.

Living robots

Living robots don't look like traditional robots. They haven’t shiny gears or robotic arms. Instead, they look more like a tiny blob of moving pink flesh. The researchers say this is deliberate. This "biological machine" can achieve things typical robots of steel and plastic cannot.

Scientists have created the world's first living, self-healing robots using stem cells from frogs. That thing was a trending topic last year. It says that people already begin the making of living robots.

https://www.youtube.com/watch?v=XLI7VtjgOyk

In addition to that, named xenobiotics after the African clawed frog from which they take their stem cells, the machines are less than a millimeter (0.04 inches) wide -- small enough to travel inside human bodies. They can walk and swim, survive for weeks without food, and work together in groups.

Algorithms shaped the evolution of xenobiotics. They grew from the skin and heart stem cells into tissue clumps of several hundred cells that moved in pulses generated by heart muscle tissue, said lead study author Sam Kriegman, a doctoral candidate studying evolutionary robotics at the University of Vermont Department of Computer Science, in Burlington.

Is a robot living or nonliving?

Scientists have come up with traits that all living things have in common. They help determine whether something is living or nonliving. A living thing is,

made up of cells
movement
organisms use energy and can get energy from a source
grow and develop
reproduction
respond and adapt to their environment

But something is in the center of this measure, like a virus. There is some doubt as to whether the virus fulfills the same criteria as autoimmune or autoimmune since it must be abducted by another organism to be fully functional.

Life, as I understand it, is tied to the concepts of self-reconstruction, self-organization, and the ability to self-determine from non-self; Man does not need the same consciousness. Except for xenobiotics, all other robots are clearly non-living but that xenobiotics are in center point like a virus.

In the future people will make robots who have self-reconstruction, self-organization, and the ability to self-determine from non-self but I have a doubt about their behaviors.

How impact Living robots on our lives?

Living robots could be used to clean up radioactive waste, collect microplastics in the oceans, carry medicine inside human bodies, or even travel into our arteries to scrape out plaque. The Living robots can survive in aqueous environments without additional nutrients for days or weeks, making them suitable for internal drug delivery.

Aside from these immediate practical tasks, the living robots could also help researchers to learn more about cell biology. Living robots will be opening the doors to future advancement in human health and longevity.

“If you think about birth defects, cancer, age-related diseases, all of these things could be solved if we knew how to make biological structures, to have ultimate control overgrowth and form,” Levin said.

Augmented reality (AR)

Augmented reality (AR) is one of the biggest technology trends right now, and it’s only going to get bigger as AR ready smartphones and other devices become more accessible around the world.

Augmented reality is a view of the real, physical world in which elements are enhanced by computer-generated input. These inputs may range from sound to video, to graphics to GPS overlays, and more. Simply put, AR let us see the real-life environment right in front of us.

AR is a totally different and developed technology than VR. (VR means a set of images and sounds, produced by a computer, that seem to represent a place or a situation that a person can take part in.) Augmented reality (AR) adds digital elements to a live view often by using the camera on a smartphone. Virtual reality (VR) implies a complete immersion experience that shuts out the physical world. Actually, AR is the future of VR.

AR’s History

Augmented reality was first achieved Morton Heilig in 1957
In 1968, Ivan Sutherland the American computer scientist invented the head-mounted display as a kind of window into a virtual world
In 1975, Myron Krueger, an American computer artist developed the first “virtual reality” interface
Steve Mann, a computational photography researcher, gave the world wearable computing in 1980.
virtual reality was coined by Jaron Lainer in 1989
Thomas P Caudell of Boeing coined the phrase “augmented reality” in 1990.
The first properly functioning AR system was probably the one developed at USAF Armstrong’s Research Lab by Louis Rosenberg in 1992.
Bruce Thomas developing an outdoor mobile AR game called ARQuake in 2000
ARToolkit (a design tool) being made available in Adobe Flash in 2009
Google announced its open beta of Google Glass (a project with mixed successes) in 2013
Microsoft announcing the augmented reality support and their augmented reality headset HoloLens in 2015

Future of the AR Technology

Future of the AR will be incredible. It will be a part of your life. Like electricity, Internet facilities and TV connections. Those things aren’t essential for us but now how many hours can you spend without those things? In the future, AR will act the same role. Internet of things (IoT) is a famous topic now. In the future, it will combine with AR so our world will be an amazing place definitely. That combine can do a lot of things. Some of them are,

Transport- In the future, instead of typing in an address into your GPS, you will be able to point to a location and the directions will pop up automatically or you will point at an object or building and receive information about it without even knowing its name. Furthermore, Some times your vehicle will be an AR design. Watch this - https://youtu.be/xBnyWWECHac
Fashion Industry – Many brands will include an AR functionality inside their mobile that will allow you to point your camera at any item and not only obtain all necessary information about it, but you will also see AR images of models wearing the clothes. This way, you will have all of the information necessary to make a smart decision without even going inside the store.
E-commerce- Shoppers can try out individual products or ready-made looks, all thanks to AR. This is an innovative way retailers have been able to bridge the gap between in-store and online shopping while also alleviating the fear of buyer’s remorse.
Digital Marketing – AR technologies will continue to improve the way customers engage with brands. Marketing AR will likely be seen in packaging, on street signs, through gaming apps, and through interactions with other products.
Geolocation – The ability of mobile devices to inform us of our surroundings be greatly improved over time. AR could benefit from everything from real-time travel advisories to restaurant suggestions.
Educational Resources – we had a lot of textbooks, loose-leaf papers, posters, and many other physical print materials. Thanks to AR, all educational materials will be interactive, digital, and available at any time. This will give a lot more people access to education and offers a higher level of student interaction since lessons can be conducted in a game format. In addition to that, you can go on field trips or any place that you study by using AR so you don't need to imagine those things.
Healthcare industry- AR can help patients understand the benefits and risks of certain medications and procedures by providing visual demonstrations or consumer scanning functionalities.AR can help medical students by offering a very intuitive representation of the human body.
Lifestyle- AR will help you to find your car in a crowded parking lot, AR also will help for cooking, shopping, and detect your diseases. To tell the truth, will be essential for you. Sometimes you will addict to it.

Top 10 cryptocurrency 2021

2021-02-16T03:03:00.012-08:00

In ancient times, there wasn’t a currency system. They used simple exchanging methods. As an example, you have a paddy field so you can grow and take vegetables, serials, fruits, and more. I haven’t a paddy field but I have a workshop because I am a blacksmith. I can make hoes, axes, sickles, and more. As a farmer, you need that equipment. At that time we can exchange our goods to fulfill our requirements. But that method has lots of issues. The difference of requirements, the problem of the value of exchanging items, and storage problems are some of them. The money came as a solution for these problems.

After the technological evolution factories were built, banking facilities grew up, product production speed increased, people were so busier so time was more valuable than money. On the other hand, open economic systems and the internet spread around the world so people need a digital system to transfer money. A solution for this problem became a digital and internet-based transfection system. Online banking, online shopping, E-commerce made as a result of that trend.

In addition to those things, by this time many people were inclined to invest money. Some people did this as trading. Somehow that business developed quickly. Trading business and market arose. There was a profitable industry but the unstable situation and currency vary between countries were occurred as the major problem. Meanwhile, cryptocurrencies came to the fore. They could solve those problems.

What is Cryptocurrency?

Cryptocurrency is a digital currency in which transactions are verified and records maintained by a decentralized system using cryptography, rather than by a centralized authority.

It can explain simply as a type of currency that uses digital files as money. Usually, the files are created using the same methods as cryptography. Cryptocurrencies haven’t a physical existence. It has only a value. That value is the same around that world. It is not usually issued by a central authority. When activated with decentralized control, every cryptocurrency operates through distributed ledger technology, usually a blockchain and serves as a public financial transaction database. Cryptocurrencies generally use more decentralized control over centralized digital money and central banking systems so that the currency system has strong protection. In addition to that, all the people can access those currencies.

History of Cryptocurrency

In 1983, an American cryptographer (a specialist in cryptography: such as a clerk who enciphers and deciphers messages.) David Chaum compiled anonymous cryptocurrency electronic money called “E-cash” .a specialist in cryptography: such as a clerk who enciphers and deciphers messages. That was the birth of cryptocurrency. After 12 years, In 1995 he activated it through "Digicash".

In 1996, the National Security Agency published a paper entitled Cryptocurrency, a cryptocurrency of anonymous electronic money. That was the first attempt to describe a Cryptocurrency system.

In 1998, Wei Dai described an electronic anonymous currency variable that calls as “B-Money”. After a short time, Nick Szabo described an anonymous currency that calls as “Bit Gold”

The first decentralized cryptocurrency, Bitcoin was created in 2009 by presumably pseudonymous developer Satoshi Nakamoto. It used SHA-256 which is a cryptographic hash function. After that creation, he developed it until December 2010 That currency was the evolution of that industry.

Are cryptocurrencies a

good investment?

All investments (such as Share market investment, Business investment, and more) have two sides. All of us like get a profit but as well as some times we get lost. That situation is the same through the investment of cryptocurrency. In addition to that cryptocurrency has advantages and disadvantages those things are a specialty for cryptocurrencies.

Advantages :

Protection from inflation
Self-governed and managed
Secure and private
Currency exchanges can be done easily
Decentralized
Cost-effective mode of transaction
A fast way to transfer funds

Disadvantages :

Can be used for illegal transactions
Data losses can cause financial losses
Decentralized but still operated by some organization
Some coins not available in other fiat currencies
Adverse Effects of mining on the environment
Susceptible to hacks
No refund or cancellation policy

I can explain those things only. You can choose your way. But I can say one thing, If you prefer to invest in cryptocurrency, you should get a clear idea about your choice after investment.

How do I buy

Cryptocurrency?

Some cryptocurrencies, including Bitcoin, are available for purchase with U.S. dollars but if you already have Bitcoin or another, you can use them for other cryptocurrencies.

In addition to that, you need another two things definitely. The first thing is a Wallet. That is an online app. You’ll need this wallet to hold your currency. Coinbase Wallet, Exodus, MyEtherWallet, StakedWallet.io. , BitGo Cryptocurrency Wallet, Jaxx, Electrum Wallet and Bitcoin Core Client are some of them.

Then you need an account of an exchange or an online cryptocurrency broker. Then you can transfer real money to buy cryptocurrencies such as Bitcoin, Litecoin, or other. The number of online brokers offers cryptocurrencies. Including:

Coinbase -Access to buy and sell more than 30 cryptocurrencies.
eToro -The trading platform with access to 15 cryptocurrencies.
Robinhood- Seven cryptocurrencies including Bitcoin, Bitcoin Cash and Ethereum.
SoFi Active Investing- Offers three cryptocurrencies for trading: Bitcoin, Ethereum and Litecoin.
TradeStation- Offers trading for five cryptocurrencies, including Bitcoin, Bitcoin Cash, and Ethereum.

Some trading exchange has both things that you need. Coinbase is one popular cryptocurrency trading exchange where you can create both a wallet and buy and sell Bitcoin and other cryptocurrencies.

How to choose a

best cryptocurrency to invest

More than 6,700 different cryptocurrencies are traded publicly, according to CoinMarketCap.com, a market research website. And cryptocurrencies continue to proliferate, raising money through initial coin offerings, or ICOs.

You already decided to invest in a cryptocurrency but you haven’t an idea what is the best crypto for your investment. Don’t afraid, I can help you.

The main things are the Community and Fundamental Analysis. The Community represents the future of a coin so look for cryptocurrencies with strong communities and loyal followers because it shows that people have a genuine interest and trust in cryptocurrency. Fundamental analysis will help you make better investment decisions. And in a market where most people are chasing after low-quality altcoins, fundamental analysis allows you to separate the wheat from the chaff.

Then you need the normal idea about the current price of the cryptocurrency. Then you can measure the market capitalization or market cap of the coin. The term market capitalization (or market cap) refers to a metric that measures the relative size of a cryptocurrency. It is calculated by multiplying the current market price of a particular coin or token with the total number of coins in circulation.

Market Cap = Current Price x Circulating Supply Fundamental Analysis

After you choose the highest or high market cap coin(that depends on your economy) as your choice. That is the way.

What is cryptocurrency trading?

The Internet offers us a lot of possibilities to work online and with the emergence of blockchain, the list of possible sources of income has increased. The biggest part of remote earning comes from cryptocurrency trading.

Cryptocurrency trading is the act of speculating on cryptocurrency price movements via a CFD trading account, or buying and selling the underlying coins via an exchange.

Cryptocurrency trading is one of the main sources of getting profit from cryptocurrency. This type of online trading is almost the same as stocks, currencies, or commodities trading. The main task is to buy when the price is low and to sell when it is higher. There are lots of cryptocurrency trading companies, Some of them are:

TradeStation - Best Trading Platform

What is Cryptocurrency

mining?

The term crypto mining means gaining cryptocurrencies by solving cryptographic equations through the use of computers. This process involves validating data blocks and adding transaction records to a public record (ledger) is known as a blockchain.

Cryptocurrency mining is painstaking, costly, and only sporadically rewarding. Nonetheless, mining has a magnetic appeal for many investors interested in cryptocurrency because of the fact that miners are rewarded for their work with crypto tokens.

There are lots of sites for mining crypto. They mainly used bitcoin for their mining. Some of them are :

Pooling- a public pool based in China, mines about 13% of all blocks
F2pool- based in China mines about 19% of all blocks
BTC.com- a public mining pool mines 1.5% of all block
Antpool- a mining pool based in China and owned by BitMainmines about 11% of all blocks
ViaBTC- targeted towards Chinese miners and mines about 8% of all blocks
1THash & 58coin- a Chinese pool, mine about 6% of the blocks
Slush- the first mining pool and currently mines about 11% of all blocks
BTC.top- a private Chinese mining pool, mines about 2.7% of all blocks
Bitfury- a private pool, mines about 3.5% of all blocks

Disease X vs Covid 19

2021-02-13T12:10:00.013-08:00

31^st December 2019, there was a day of hope because the next day is the 1^st day of 2020. But this wasn’t the case for Chinese doctors, a patient came who has an undetected disease. All doctors were confused because his symptoms were very similar to those of the coronavirus family disease. They already faced the horrible of Severe acute respiratory syndrome-related coronavirus (SARSr-CoV or SARS-CoV) is a species of coronavirus that infects humans, bats, and certain other mammals, and Middle East respiratory syndrome (MERS) is a viral respiratory disease caused by a novel coronavirus (Middle East respiratory syndrome coronavirus, or MERS‐CoV). By the time they know the correct information about it, everything that should have happened is over. That’s not their fault. That’s the danger of a virus.

After a month the virus became a pandemic. It is difficult to say how devastated the virus was. A lot of people thought that this is the disease X but tests showed that this was not the case before work was over. Disease X is so dangerous than Covid 19.

What is Disease X?

Disease X is a placeholder name that was adopted by the World Health Organization (WHO) in February 2018 on their shortlist of blueprint priority diseases to represent a hypothetical, unknown pathogen that could cause a future epidemic.

Professor Jean-Jacques Muyembe Tamfum, the doctor who discovered Ebola warned that a fresh set of deadly viruses will hit mankind as he fears Disease X which could be as fast-spreading as the COVID-19, and as deadly as the Ebola virus, reports CNN.

The average Ebola case fatality rate is around 50% and Covid-19 has 1-1.5 R rate, it means an R of 1.5 would see 100 people infect 150, who would, in turn, infect 225, who would infect 338. According to that disease X can massacre about half of the world. That will become the darkest period of the earth.

Today it’s probably in a forest somewhere miles from the nearest city, but that can change quickly. It’s estimated that a respiratory virus similar to the flu could reach all major global capitals within 60 days. It’s our expertise and multidisciplinary approach that stands between you and the next pandemic.

Disease X patient zero

Patient zero used to refer to the person identified as the first carrier of a communicable disease in an outbreak of related cases.

A few months ago, a patient came by sowing early symptoms of hemorrhagic fever, the patient sits quietly on her bed, wrangling two toddlers desperate to flee the cell-like hospital room in Ingenta, a remote town in the Democratic Republic of the Congo (DRC). She was tested for Ebola and even coronavirus, but all her test reports came out to be negative. This new infection could be more fateful than Ebola and Covid-19, Prof. Tamfum said. His statement is since doing round in world media, raising several questions if this "Disease X" is indeed a news disease. But, you already know the answer by now.

Prof. Tamfum also cautioned that many more zoonotic diseases, specifically those that get transmitted from animals to humans, could arise in the future. He stated that diseases -- namely influenza, rabies, and yellow fever -- have all jumped from animals to humans. These "occurrences are common and could lead to epidemics and pandemics in the future", he said.

That is our luck but one-day disease x will be true. Although it true, the situation will be so dangerous. So I hope, it won't be so. But we can’t escape from nature, we should prepare for it always.

Can we discover

diseases X?

There are 1.67 million unknown viruses on this planet. Using our best estimates, anywhere between 631,000 and 827,000 of those have the ability to infect people. Scientists currently know of only 263 viruses that can infect people, which means that we know almost nothing about 99.96 percent of potential pandemic threats.

We know which species are most likely to be carrying Disease X. We know the viral families to which Disease X is most likely to belong and, therefore, which known viruses are likely to be similar. Thanks to our hotspots map of global pandemic risk, we know the parts of the world where Disease X is most likely to make the jump to people.

EcoHealth Alliance is committed to the Global Virome Project, a visionary undertaking that seeks to find and study the vast majority of the world’s 1.67 million unknown viruses. The hope is that we can learn everything to know about Disease X before it strikes. According to a paper published in Science by many of the Global Virome Project’s architects–including EcoHealth Alliance President Dr. Peter Daszak–in just 10 years we could discover 71 percent of those undiscovered viruses.

Therefore sometimes scientists can be discovered disease x before it spread around the world. But it won't be the end of potential pandemic threats. Because the environment has something that the average mind doesn't understand.

In addition to Disease X, other viruses -- some of them now-well-known deadly viruses -- on WHO's current priority list are:

World in Future-01

2021-02-11T11:01:00.010-08:00

PART-01

Before 3 or 4 centuries, we just didn’t have enough technology for everyday life. But after the evolution of technology, we had a lot of things. It is so fantastic that I like the wild after the rain. All of us know that but one thing acts as the main role behind the screen. We didn’t see it. It is the Science. We can’t touch or see that but the real hero is the science.

Scientists are working every day to make our world a safer, efficient, and more amazing place. Until today, they did it superbly. It will be the same in the future so we will see a lot of fictional things just as true with our own eyes.

I would like to explain my top 10 among them those will fiction Ideas and Technologies that could be possible in the distant future.

Artificial Super

Intelligence

"It [strong AI] would take off on its own, and re-design itself at an ever-increasing rate. Humans, who are limited by slow biological evolution, couldn't compete, and would be superseded."

Stephan Hawking

We can divide AI into three main parts. They are,

Artificial narrow intelligence or applying AI only to specific tasks
Artificial general intelligence – applying AI to several areas and autonomously solving problems that AI software was never even designed for.
Artificial super intelligence – AI capable of scientific creativity, social skills, and general wisdom.

You can say that AI has already come true because people talk about AI normally. We find AI in our phones, computers, and robots. If you know the depth of that topic, you never say it like that. The best example is that the technologies which you use are just in the first stage. Strong AI contrasts with weak AI, which is the application of artificial intelligence to specific tasks or types of problems. IBM's Watson supercomputer, expert systems, and the self-driving car are all examples of weak or narrow AI. Even in the current state of technology, the systems' ability to access and process data is impressive: ROSS, a legal expert system sometimes called the AI attorney, can mine data from about a billion text documents, analyze the information and provide precise responses to complicated questions in less than three seconds. I think now you can understand the power of AI and the depth of the AI.

How impact AI our future?

The machine would require an intelligence equal to humans
Cyborg Technology-One of the main limitations of being human is simply our own bodies—and brains
Taking over dangerous jobs-Robots are already taking over some of the most hazardous jobs available, including bomb-defusing but in the future, it can be dangerous
Solving climate change
Robot as friends
Improved elder care

We can't just explain about the super AI correctly but it will succeed near future. Can imagine our future with super AI?

Brain-Computer Interface

A Brain-Computer Interface (BCI) is a system that measures the activity of the central nervous system (CNS) and converts it into an artificial output that replaces, restores, enhances, supplements, or improves natural CNS output, and thereby changes the ongoing interactions between the CNS and its external or internal environment.

BCI technology allows a human brain and an external device to talk to one another to exchange signals. It gives humans the ability to directly control machines, without the physical constraints of the body.

That technology has already developed and is coming soon. Leading the way is Elon Musk's company "Neuralink" which is looking to add a chip for your brain. The chip, which Neuralink calls the "Link," will wirelessly connect the brain to the digital world, starting by connecting to a smartphone. The resulting computing power, according to Musk, will allow humans to be broadly competitive with rapidly developing AI.

Brain-computer interfaces have contributed to various fields of research. They are involved in;

Medical- Healthcare field has a variety of applications that could take advantage of brain signals in all associated phases including prevention, detection, diagnosis, rehabilitation, and restoration.

Neuroergonomics and the smart environment- Smart environments such as smart houses, workplaces, or transportations could also exploit brain-computer interfaces in offering further safety, luxury, and physiological control to humans’ daily life. that will be the future of the Internet Of Things(IoT).
Neuromarketing and advertisement - As a result of the BCI, EEG evaluation for TV advertisements related to both commercial and political fields, estimating the memorization of TV advertisements thus providing another method for advertising evaluation.
Educational and self-regulation- Neurofeedback is a promising approach for enhancing brain performance via targeting human brain activity modulation. It invades the educational systems, which utilize brain electrical signals to determine the clarity of study information. On the other hand, EEG based emotional intelligence has been applied in sports competitions to control the accompanying stress
Games and Entertainment- Combining the features of existing games with brain-controlling capabilities will be an amazing thing that tends to provide a multi-brain entertainment experience. Furthermore, EEG serious games have been employed for emotional control and/or neuroprosthetic rehabilitation. They are containing either a new game idea or a modified one.
Security and Authentication fields- They have shown to be vulnerable to several drawbacks such as simple insecure passwords, shoulder surfing, theft crime, and cancelable biometrics. Cognitive Biometrics or electrophysiology, where only modalities using biosignals (such as brain signals) are used as sources of identity information, gives a solution for those vulnerabilities EEG signal generated from driving behavior as part of smart driving systems

Mars States

“You want to wake up in the morning and think the future is going to be great - and that’s what being a spacefaring civilization is all about. It’s about believing in the future and thinking that the future will be better than the past. And I can’t think of anything more exciting than going out there and being among the stars.”
-Elon Musk-

Why Mars;

Mars is one of Earth's closest habitable neighbors
It is a little cold, but we can warm it up
We can grow plants on Mars just by compressing the atmosphere
Gravity on Mars is about 38% of that of Earth, so you would be able to lift heavy things and bound around.
The day is remarkably close to that of Earth

If you had seen the Martian film what is a 2015 science fiction film directed by Ridley Scott and starring Matt Damon, you would have an idea about the difficulty of living on Mars.

What are the difficulties of living on Mars?

The atmosphere of Mars is composed mainly of carbon dioxide (95.3%), nitrogen (2.7%), and argon (1.6%), with small amounts of other gases. The surface seems to have abundant silicates and traces of iron oxides, which are responsible for the reddish color (solid).
Mars is about half the size of Earth. If Earth were the size of a nickel, Mars would be about as big as a raspberry.
As Mars orbits the Sun, it completes one rotation every 24.6 hours, which is very similar to one day on Earth (23.9 hours). Martian days are called sols—short for "solar day." A year on Mars lasts 669.6 sols, which is the same as 687 Earth days.
Mars is 1.5 astronomical units away from the Sun. One astronomical unit (abbreviated as AU), is the distance from the Sun to Earth.
Mars is home to the largest volcano in the solar system.
Health Challenges
Food and Water

Although this project is so difficult, scientists could solve a lot of problems. And also they try to achieve other things too.

How do we overcome those problems?

Powerful propulsion systems to get us there (and home!) quicker
Inflatable heat shield to land astronauts on other planets
High-tech Martian spacesuits
Martian home and lab on wheels
Uninterrupted power
Laser communications to send more information home

Scientists are around the world dedicated to achieving these goals. Among them NASA and the SPACE X act the main roles of this film. Not only that UAE, China, Russia, and India also try to achieve that.

SPACE X ;

In 2022, at least 2 Starship cargo vehicles will land on Mars.
- They will confirm water resources and identify hazards.
- They will place power, mining, and life support infrastructure for future missions.
In 2024, 2 Starship crew vehicles will take the first people to Mars.
- 2 Starship cargo vehicles will bring more equipment and supplies.
- They will place a propellant production plant.
- They will build up a base to prepare for expansion.
If these launch windows were missed, the same mission architecture could be carried out in subsequent 2-year intervals.

NASA ;

The first attempt to win Mars- 5 November 1964, Mariner 3( Launch failure)
First successful attempt to win Mars- 28 November 1964, Mariner 4
All missions to Mars-23
Last Mission- July 30, 2020, Mars 2020(The first step to the human mission)
NASA is developing the capabilities needed to send humans to an asteroid by 2025 and Mars in the 2030s.

In my opinion, we can win mars quickly, but it won't be an easy target. Earth is our mother so any other can't replace that place. No substitution for Earth because of that reason We Should protect our planet. Keep that in your mind every day.

My top 10 Upcoming phones 2021

2021-02-09T08:36:00.005-08:00

The 2020 year was rough because all of us faced a pandemic call as “COVID 19”. That case affected all industries around the world. As well as the technology industry faced for it, Smartphone manufacturers have rolled back production in light of the pandemic. Production slowed as a result of global supply chain disruption. In addition to that Falling Demand for New Phones, Declining Production, Rising Smartphone Usage but they wouldn't be able to maintain normal production levels even if it were economically viable, Changing Market Shares for Manufacturers and Mixed 5G adoption treated highly for that industry.

On the other hand, the introduction rates of mobile phones don’t change highly. As an example, there are 80 new smartphones introduced in 2019. It became 72 in 2020 but it hasn’t hugely different. It is a victory for them.

Now we are in 2021. The covid pandemic is not over until now but we are preparing for a new normal lifestyle so lots of companies were back with their best devices. In my opinion, 2021 will be a great season for the smartphone manufactory industry. 2021 has got off to a good start, as we've already seen the Samsung Galaxy S21, Samsung Galaxy S21 Plus, and Samsung Galaxy S21 Ultra from Samsung, Vivo X60 from Vivo, and Xiaomi MI 11 from Xiaomi. That’s only the beginning. Lots of fascinating things are on the way.

Vaccines and Immunization

2021-02-07T02:52:00.076-08:00

Vaccines and Immunization

What is a vaccine?

A vaccine is a type of medicine that can increase the strength of our immune system so it helps to destroy or suppress the pathogen if it has not come into the body before. It uses your body’s natural defenses to build resistance to specific infections and makes your immune system stronger. Vaccines are designed to prevent disease, rather than destroy a disease once you have caught it.

Vaccines train your immune system to produce antibodies, just as it does when it’s exposed to a disease. Vaccines contain only killed or weakened forms of germs like viruses or bacteria therefore they do not cause the disease or put you at risk of its complications. Most vaccines are given by injection, but some are given orally (by mouth) or sprayed into the nose.

Lots of diseases that occur as a pathogen have vaccines so some diseases are almost forgotten because of the vaccine. Some of them are:

Diphtheria
Two shots help protect children against diphtheria: DTaP a Tdap. Both also help protect against tetanus and whooping cough.
Whooping Cough
Five doses of the DTaP shot and a Tdap booster shot are recommended for children and preteens by doctors as the best way to protect against whooping cough (pertussis).
Hepatitis B
Three doses of the hepatitis B shot are recommended for children by doctors as the best way to protect against hepatitis B.
HPV
HPV vaccination is recommended at ages 11-12 to protect against cancers caused by HPV infection.
Measles
Two doses of the MMR vaccine are recommended for children by healthcare providers as the best way to protect against measles, mumps, and rubella.
Meningococcal
Two doses of the meningococcal shot called MenACWY are recommended for preteens and teens by doctors as the best way to protect against meningococcal disease.
Mump
Two doses of the MMR shot are recommended for children by doctors as the best way to protect against measles, mumps, and rubella.
Polio
Four doses of the polio shot for children are recommended by doctors as the best way to protect against polio.
Rotavirus
Two or more doses of a rotavirus vaccine are recommended for children by doctors as the best way to protect against rotavirus.
Tetanus
Five doses of the DTaP shot and a Tdap booster shot are recommended for children and preteens by doctors as the best way to protect against tetanus.

More details-https://www.youtube.com/watch?v=xocY96VaMHA&t=54s

Vaccines are very useful. But sometimes it has some adverse results. It depends on your age, health, or other natural things. The side effects that do occur are usually mild, and may.
include:
Redness, swelling, or pain where the shot was given
Fever
Vomiting
  What is Immunization?

Immunization is the process whereby a person is made immune or resistant to an infectious disease, typically by the administration of a vaccine. Vaccines stimulate the body's own immune system to protect the person against subsequent infection or disease. The vaccine is a one way for immunization but no the only way. There are lots of things that can help with immunization. In my opinion, we should focus on those things. They are:
Dietary patterns
Environmental conditions
Mental health
Life style
Social conditions

In my opinion, if you can consider those things, you can protect from many diseases although have a vaccine or not against a disease. As an example, Lots of cancers haven’t vaccines but we can’t hide from them. SO WHAT CAN WE DO? We must do some essential things. They are the things that I explain above. Not only that but Chagas disease (American trypanosomiasis), Chikungunya, Dengue, Cytomegalovirus, HIV/AIDS, Hookworm infection, Leishmaniasis, MalariaRespiratory, Syncytial Virus, Schistosomiasis also haven’t vaccines.

Loriciferans

Loricifera is a phylum of very small to microscopic marine cycloneuralian sediment-dwelling animals with 37 described species, in nine genera. there are approximately 100 more that have been collected and not yet described. Their sizes range from 100 μm to ca. 1 mm.
