What is an atomic clock?

2009-05-25T04:08:00.000-07:00

Atomic clock is a special type clock that shows almost accurate time. Atomic clock maintains continuous and stable time scale. the first model of atomic clock was build on 1949 by the U.S National Bureau of standards. First successful atomic clock was designed on 1955 in UK by National physical laboratory. A chip scale atomic clock designed in august 2004 by NIST scientists. Chip type atomic clock consumes only 75 mw current. Major application of atomic clocks are to generate standard frequency and serve time signals to time signal sites. They also installed at navigation transmitters and broadcasting stations. By the help of this atomic clock signals broadcasting stations produces accurate carries frequency. GPS navigation systems base signals are also from atomic clock.

How many languages are in the World?

2009-05-23T08:33:00.000-07:00

When people are asked how many languages they think there are in the world, the answers vary quite a bit. One random sampling of New Yorkers, for instance, resulted in answers like “probably several hundred.” However we choose to count them, though, this is not close. When we look at reference works, we find estimates that have escalated over time. The 1911 (11th) edition of the Encyclopedia Britannica, for example, implies a figure somewhere around 1,000, a number that climbs steadily over the course of the twentieth century. That is not due to any increase in the number of languages, but rather to our increased understanding of how many languages are actually spoken in areas that had previously been underdescribed. Much pioneering work in documenting the languages of the world has been done by missionary organizations (such as the Summer Institute of Linguistics) with an interest in translating the Christian Bible. As of 1997, at least a portion of the Bible had been translated into 2,197 different languages, still a long way short of full coverage. The most extensive catalog of the world’s languages, generally taken to be as authoritative as any, is that of the Ethnologue organization

(http://www.ethnologue.com), whose detailed classified list currently includes 6,809 distinct languages.

How "Ida" named new fossil help the study about human origins?

2009-05-21T08:33:00.000-07:00

Ida is a new fossil found in Germany that will help to created a good media attention and will likely continue to make waves among those who study human origins.

The paleontologist team that analyzed the 47-million-year-old fossil seen above, suggests Ida is a critical missing-link species in primate evolution. This fossil, reduces the gap between higher primates (monkeys, apes, and humans) and their more distant relatives such as lemurs.

What is Casimir force?

2009-05-19T20:40:00.000-07:00

When two uncharged metals are kept micrometers away from each other in a vaccum. There is a quantum force betwen them (repulsion or attraction) depending upon the arrangement of the metals. The repulsion properties of casimir force can be used in levitationg micro objects. Casimir force is very significant in nanotechnology as this helps to reduce the friction between submicromillimeters parts. Since this force is created in vaccum It is also described as force from nothing.

What Is Biogas?

2009-05-03T00:22:00.000-07:00

Biogas is a mixture of carbon dioxide, methane and some other gases. It is produced by some kinds of microorganisms, usually when air or oxygen is absent. (The absence of oxygen is called “anaerobic conditions.”) Animals that eat a lot of plant material, particularly grazing animals such as cattle, produce large amounts of biogas. The biogas is produced not by the cow or elephant, but by billions of microorganisms living in its digestive system. Biogas also develops in bogs and at the bottom of lakes, where decaying organic matter builds up under wet and anaerobic conditions.

When was history made in twelve seconds?

2009-03-05T16:53:00.000-08:00

The date was 17 December 1903; the scene: the cold windy hills of North Carolina; the name of the place which was to go down in history: Kitty Hawk; the occasion: man’s first powered flight. The aero plane had arrived. Orville Wright was at the controls. The aircraft, powered by a four cylinder engine, careered through space for twelve seconds at 48Km. p.h. airspeed, swept down and landed in soft sand. Orville wrote: ‘This flight lasted only twelve seconds but it was, nevertheless, the first in the history of the world in which a machine, carrying a man, had raised itself by its own power into the air in full flight, had sailed forward without reduction of speed and had finally landed at a point as high as that from which it started’. The Wrights’ aircraft was called flyer. Only five people were there to watch it make history. One photograph recorded the scene. It was not until three years after Kitty Hawk that the Scientific American wrote” ‘In all the history of invention there is probably no parallel to the unostentatious manner in which the Wright Brothers of Dayton, Ohio, ushered into the world their epoch-making invention of the first successful aeroplane flying machine’.

How do we see?

2008-12-02T00:42:00.000-08:00

The human eye is shaped like a ball with a bulge in the front. In the middle of this bulge is a hole called the pupil, which is the part we see as the black circle in the middle of the colored iris. The pupil lets in light to the eye. Behind it is the lens, which focuses the picture of what we can see. When light passes through the lens. It is turned upside down, so that an upside down pictures is the image which hits the retina.
The retina is the part of the eye which actually makes sense of what we see. It is sensitive to light, and can sort out all the different colors we see. When light hits the cells of the retina, a chemical change takes place in the cells. This starts message or impulses in the optic nerve at the back of the eye, which takes these messages to the brain. The brain turns the images the right way up, and identifies them as something we can recognize. Have you ever wondered why the pupils of the eyes grow bigger and smaller? This happens according to the amount of light available. In bright light, the pupil closes up to black speck, letting through only enough light to be able to see without damaging the retina. When the light is very dim, the pupil opens up to let in as much light as possible, so that, again, we can
see.

What is a Dowser?

2008-12-01T18:36:00.000-08:00

A dowser is another name for a water-diviner – someone who can tell where there is water lying underground. The dowser uses a whole variety of tools to find the water, but one of the most common is the Y-shaped twig from a hazel tree. The dowser holds the twig by the two prongs of the Y, with the long stem pointing upwards. When the twig is above a spot where there is water beneath the surface of the earth, the stem of the twig will suddenly dip downwards, or in some cases it will twist itself violently out of the hands of the dowser.

Nobody knows exactly how this is done, not even the dowsers themselves, but it may be that they have some special powers which the rest of us don’t possess – it is certainly true that only a very few people can do this.

Why don’t we all have the same color hair?

2008-11-13T05:38:00.000-08:00

Melanin, as brown pigment which gives color to skin, also gives color to hair. Because some people have more melanin, they have darker hair. Hair colors range from blond to black. People who have a shortage of pigment have very pale skin, hair and eyes. They are known as albinos.
Old people have grey hair because as the body gets older it produces less melanin, so the natural hair color fades.

What are nerves?

2008-11-13T05:24:00.000-08:00

Nerves are the organs which tell us what is going on in the world outside our bodies, and which take messages about this world outside our bodies, and which take messages about this world to the brain, which translates the messages into feelings. There are four types of nerve in the body. The first is the one which picks up messages like pain, light, cold and heat. The second type of nerve receives these messages and sends others to parts of the body which cause swift action to be taken. For example if you touch a hot iron, the first type of nerve tells you it is hot, and a spilt second late the second sort of nerve makes your muscles pull your hand away in what is called a reflex action. The third type of nerve takes messages over longer distances in the body, and is the type of nerve which makes our body do the things our brain orders it to do, such as moving parts of the body to perform certain actions. The final sort of nerve is that which transmits messages from the first type, called sensory nerves, to the brain where the messages are translated into feeling. This is why, having touched the iron, we may not feel the pain until just after we have pulled our hand away. We have nerves all over our body, although there are more in certain parts than in others. The central nervous system, through which all messages pass, is composed of the brain and the spinal cord, which is why we have to take special care not to damage our head or backs.

Which animals and plants are in the most danger?

2008-10-01T00:44:00.000-07:00

In this question, the ‘word’ danger does not refer to the danger to which individuals of any species may be subjected. Danger in this case means the danger to which a whole species is liable. In other words, species may be in danger of becoming extinct, and disappearing for ever from the face of the planet. Of course, we can tell from the fossil record that hundreds of species of animals and plants have come and gone throughout the span of life on Earth. In the past, however, those species that have died out have done as a result of natural causes. The animals and plants that disappeared were those that were unable to adapt fast enough to changing conditions or were unable to compete with their rivals for the available food supplies. There are instance, however, such as that of the dinosaurs, in which it is not at all clear why they became extinct. Many dieas have been suggested, but none of them is wholly satisfactory.
For today’s wild life, there is another, more terrible threat to their existence – man. Man is endangering the lives of many species of animals and plants which are unable to adapt to the pressure of man’s increasing numbers and his changes to the natural environment. On the other hand, there are those species that have certainly benefited from man’s activities. In Britain, for example, birds such as the black headed gull have increased in numbers quite dramatically in the last fifty years, adapting well to a semi-urban environment and feeding on man’s waste. Even the fox has been able to survive by adapting to become an urban scavenger in many large cities. Unfortunately, the lack of suitable foods has led to the foxes becoming deformed so that individual probably spends a great deal of their lives in considerable pain.
But man is threatening wild life in many ways. Firstly by his spread further and further into the rural areas, man is reducing the areas in which wild life can live. This also includes the effects of widespread farming where forests and heaths come under the plough and many kilometers of hedges are removed. Secondly, man has hunted many animals to extinction. A good example of this is the destruction of the great auk during the last century or perhaps even more famous the death of the dodo. More recently the fate of many species of the giant sea mammals, whales, has been in the news, as their numbers fall to the more efficient whaler’s harpoon gun with its explosive harpoon. Pollution is also affecting the lives of many animals. Millions of sea birds die very unpleasant deaths as a result of their feathers becoming covered in sticky, black oil waste.
It is sometimes argued that if an animal or plant cannot survive man’s ravages, then this is just the course of evolution. Unfortunately, many beautiful and valuable species, on which man himself depends, may never be seen again.

What is Unicorn?

2008-09-19T23:49:00.000-07:00

On the royal coat of arms of Britain there are two creatures, one on either side of the shield. One animal is, of course, the lion and the other is a strange, horse-like creature with a long elegant horn on its forehead. This is the unicorn. It is a creature of legend, and probably never existed; the tales of it brought back by ancient travelers were probably the result of sighting of rhinoceroses and a good deal of imagination. Nowadays, nobody believes in the unicorn except as a legendary animal, and a heraldic beast, but years ago people did believe in its existence.

Queen Elizabeth the First was supposed to have possessed a unicorn’s horn, which was worth an enormous sum of money, and the horn was supposed to have healing powers and could protect people against poison. There were special rules and down about how to catch a unicorn. A Young girls was the effective bait, and unicorn would lay its head in her lap while the hunters crept up to do their work. The Unicorn became part of the British coat of arms when Scotland and England were first united under King James the First. Before that England’s heraldic beasts were a lion and a dragon and Scotland’s were two unicorns. Legend has it that the two beasts, the lion and the unicorn, were deadly enemies and that the only way to stop them killing one another.
