The modern day telescopes bring with them a wide array of accessories and it is with the aid of these accessories that it becomes much more easier to successfully put the telescopes into proper use. Let us see what are the important accessories that go well and are a must-have for most telescope users: -

Filters- These are very essential for telescope users because they reduce the glare on the eyepiece and scatter the light thereby making it less strenuous for us to view distant objects.

Eyepiece- this is a very important piece of equipment and its absence can render a telescope useless. Eyepieces come in a variety of sizes and if you add more than one eyepiece to your telescopes then you can have the pleasure of viewing even the tiniest and distant objects with clarity.

Mounts- Mounts are the stands for telescopes. It is a mount on which the telescope rests. Since a telescope wont function favorably in vibrations therefore you should ensure that it is placed on a stable mount.

Barlow lens- A Barlow lens helps in the magnification of telescopes. These lenses are available in different sizes and we must be careful in choosing the size that best fits the eyepiece.

There are two main types of telescopes, the refractor (Galileo) telescopes and the reflector (Newton) telescopes. The refractor telescope uses an objective lens that bends the light towards the eyepiece. While the reflector telescope uses a mirror, which collects the light and then directs it towards the eyepiece.

Though both the refractors as well as the reflector telescopes are easily available in the market we should take the following points into consideration before buying a telescope.

Do not get impressed by the magnification of the telescopes. This is because magnification alone is of no use if it just produces large but hazy images.

Aperture- This is the most important factor while deciding on a telescope. Aperture is the opening that collects light so its important to choose a telescope with a larger aperture that will ensure a clearer and a more detailed image quality.

Resolution- This enables the telescopes to produce a more detailed image. So always opt for a telescope, which has a higher resolution. Moreover since resolution is also determined by the aperture, therefore the larger the aperture the better the resolution.

Focal length- The distance between the optical center of the lens or the mirror and the optical center of the eyepiece is known as the focal length. The focal length is what determines the magnification in telescopes. Larger focal lengths imply more magnification.

If we are careful about remembering the above points then it wont take us long to choose a telescope the next time we want to buy one for ourselves.

The National Science Foundation mostly provides research funding in the form of grants. These grants are most often given in the form of individual grants to graduate students and professors. In fact, with an annual budget of approximately $5.5 billion, the National Science Foundation provides about 20% of federally supported funding for basic research to Americas universities and colleges.

Under the leadership of its director, Dr. Arden L. Bement, Jr., the National Science Board meets six times per year to determine the policies of the National Science Foundation. The National Science Board consists of 24 members, all of which are appointed by the President of the United States to 6 year terms.

History of the National Science Foundation

The National Science Foundation was originally established as the result of the 1950 National Science Foundation Act. The mission of the National Science Foundation, as stated within this act, was To promote the progress of science; to advance the national health, prosperity, and welfare; and to secure the national defense.

The National Science Foundation has competed with defense research agencies, such as the Office of Naval Research, the Defense Advanced Research Projects Agency, and the Air Force Office of Scientific Research, for funding. This battle for funding has led many science historians to claim that the National Science Foundation is an inept compromise between visions within the federal government in regards to the scope and purpose of the foundation.

Programs of the National Science Foundation

Fields within the National Science Foundation include: astronomy, physics, behavioral science, biology, chemistry, and computer science. Economic science, social sciences, science education, engineering, environmental science and education, polar research, geoscience, mathematics, and statistics are also fields covered by the National Science Foundation.

In addition to working within its regular fields, the National Science Foundation promotes a variety of special programs. These programs are sometimes put into place in order to increase the participation of under-represented minorities in the sciences. The Research Experience for Undergraduates program, for example, targets minorities and women. This program provides grants to institutions in order to assist them in providing opportunities for summer research to undergraduate students.

In addition, the GK-12 Crosscutting Program was established by the National Science Foundation to provide universities with money to encourage graduate students to interact with k-12 students. The goal of this program is to increase science retention in children at an early age.

The National Science Foundation also funds projects on a national scale. One such project is the National Science Digital Library. Also, the National Science Foundation helps pay for the establishment of the Materials Research Science and Engineering Centers that are located in some research universities.

Space exploration and the National Science Foundation

At times, there is conflict between the National Science Foundation and the National Aeronautics and Space Administration (NASA). This is because both agencies strive to increase knowledge regarding the universe, space, and the human body. Neither, however, wants to pay more than its fair share for this research. Furthermore, clear guidelines concerning which agency is responsible for which aspects of the fields have not been established.

Currently, the two agencies have developed a truce of sorts. Under the unofficially structured guidelines, NASA is responsible for paying form space based operations. These include projects such as Chandra, the Hubble Space Telescope, and the Spitzer Space Telescope. The National Science Foundation, on the other hand, funds ground based operations. These include the National Radio Astronomy Observatory, the Atacama Large Millimeter Array, and Kitt Peak.

Generating electricity from the sun is all about converting sunlight into power. Importantly, the process has nothing to do with converting the heat produced by sunlight into energy. This common misconception leads to a lot of confusion regarding solar systems.

The technology behind solar systems is known as photovoltaic technology. Essentially, this technology involves using sunlight to create a chemical reaction. During the chemical reaction, electrons are released from the relevant material and collected by tiny wires. This process creates a direct current of electricity. The electricity is then converted to usable alternating current electricity and stored in a battery or fed into a utility grid system.

Solar platforms use this exact process to produce energy. The arrays are made up of small squares called photovoltaic cells. A collection of these cells forms a single panel and a collection of panels makes up a solar array. The size of your array is entirely dependent upon the amount of electricity you want to produce.

The photovoltaic cells in a solar array are where the action happens. The cells are typically made with crystalline silicon under a glass cover. When sunlight hits the crystalline silicon, the material reacts by kicking off electrons. Tiny wires built into the cells collect the electrons in the form of an electrical current. This current is then sent to an inverter, which converts it to usable electricity.

The biggest issue with solar platforms is how efficiently they convert sunlight into electricity. The answer depends on how much you want to spend. Top brands will convert at roughly 15 percent efficiency. Less expensive brands will convert at 5 to 10 percent efficiency. The more efficient the panels, the fewer you will need.

It has become clear that our reliance on fossil fuels is only going to lead to further problems, whether political, environmental or economic. Advancements in solar technology as well as incredible tax breaks and rebates make using the Sun as an energy source a viable solution for you.

Using Biomass Power for Our Electric Needs

Biomass is a term used to describe natural, biological materials that can be used as fuel to produce energy. Biomass is a broad term that includes many different types of fuels, from garbage to landfill gas to ethanol. The electricity biomass produces can be used to power many different things from industries to homes, and once properly researched and put into use, biomass will definitely cut down on the world’s use of fossil fuels and other harmful sources of energy.

The most common types of biomass can be grouped into one of three categories. Wood (and related) products are things like lawn clippings, wood chips, leftover wood scraps from lumber production, dead trees and leaves. Garbage products are items within garbage that people generate that can be used to burn as fuel, or landfill gases, which are produced when garbage rots (methane). Ethanol and biodiesel are both fossil fuel replacements made from either corn or other crops (ethanol) or vegetable oil and animal fat (biodiesel). All of these can result in biomass fuel to produce electricity.

The landfill gas, also known as biogas or methane, is often collected by landfill owners or farmers to be used as fuel. The burning of this fuel can either power a generator for electricity or be used to heat property. The vegetation or wood related products can be pressed into pellets, and then used as fuel for heat and electricity generation. Ethanol and biodiesel are of even more interest in the world climate these days, as they are both used to power cars and other vehicles. Ethanol and biodiesel are much cleaner burning than fossil fuels, and less expensive to produce since they come from waste which is easy to find in our modern world. Both types of fuel are also biodegradable, making them safer for the environment. While neither fuel can be used in all types of cars at present, car manufacturers are working to make more vehicles that will run on these alternative fuels. Any of these approaches can be used as electricity biomass platforms.

While the idea of using electricity biomass as a power platform may seem far-fetched at present, the resources are already in place to use biomass as fuel. What needs to be done right now is more research on how to use these biomass fuels efficiently, and without the stigma of burning garbage. Other fuels at present are much more user-friendly and easy to store, as they are concentrated and in familiar formats.

Once we learn to concentrate biomass and make it easily usable, it will be a great alternative to any of the other energy sources available today with the possible exception of nano-solar technology. Electricity biomass as an energy platform is definite a concept coming into its own.

Here is my seven step description of the scientific method.

1. Define the question 2. Gather information and resources 3. Form hypothesis 4. Perform experiment and collect data 5. Analyze data 6. Interpret data and draw conclusions that serve as a starting point for new hypotheses 7. Publish results

In science fair competitions, if you can show that you are following the scientific method, you are well on your way to impressing the judges.

Basically, start out by defining your question and topic. After that, form a hypothesis and perform your experiments. Step 6 is where you use that data to make any new hypotheses or theories about your science topic. If you want, you can take that new hypothesis you just developed and start again from step 3, then move your way back to 6. Follow this cycle as much as you want. The more focused your information and experiments the better.

Would you like an example to clarify how to use the scientific method?

Imagine you are doing your project on “Hot water” and we are going to follow the scientific method steps.

1. Define your question.

How about something silly, like “Will boiling water burn a person’s hand?”

2. Find lots of information about hot water and learn everything you can about it.

3. Now form a hypothesis based on your research. Our hypothesis is, “A person will not suffer any burns due to contact with boiling water.” Hopefully you are smart enough to know this isn’t true, but let’s pretend we aren’t just for the sake of the example.

4. Now we do perform our experiements. In real life we know we will burn ourselves with boiling water, and we should never touch it! But, suppose the experimenter has no idea. They run tests to see if contact with boiling water burns a person. BAD IDEA!

5. Now look at your data. Probably everyone in the experiments burned their skin during the tests. Looks like boiling water does cause burns! DUH!

6. Interpret the data. Hmm…our hypothesis was completely wrong. Our experiments showed that boiling water can cause burns.

7. Publish your results. I certainly hope you never make a project just like this, but here’s your chance to show the world what happens when you touch boiling water!

Keep in mind, don’t change your hypothesis because your final data did not agree with it. You don’t get more credit for having a correct hypothesis. You get credit for following the scientific method and coming to a correct conclusion based on your data.

Don’t forget to include possible reasons for experimental error.

If you follow these steps your project or experiment will make sense to anyone who views it and you have a good chance of succeeding!

How the ECM works:

A number of sensors are available that provide the ECM with the information it needs, such inputs are engine and ambient temperature, vehicle speed and load. The ECM makes adjustments by advancing or retarding the ignition timing, adds or subtracts fuel or increases and decreases the idle speed.

In the exhaust, before the catalytic converter, an oxygen sensor monitors the quality of the combustion produced in the cylinders. The sensor produces a feedback that is then used by the ECM to make fine adjustments to the fuel-air mixture with the objective to reduce emissions. After the catalytic converter, another sensor in the exhaust monitors it’s efficiency

Other additional emission control systems exist, such as the Evaporative System, or EVAP. The objective of EVAP is to prevent vapors of gasoline, from the gas tank, from being released into the atmosphere. There are also a number of sensors and actuators that are controlled by the ECM.

The operation of sensors and other engine components is constantly tested by the self-diagnostic capability of the ECM. If one of the signals is missing or if it’s not in the normal range then the Check Engine light is illuminated and the Diagnostic Trouble Code, DTC, is stored in the memory of the ECM. The Check Engine light will be illuminated also if a mechanical component, such as the EGR valve, fails.

With a special scan tool, the stored code can be retrieved by a technician, that will then know only a direction where to look for. The code doesn’t tell specific information about the failure, certain tests have to be performed for each code, in order to find the exact cause of the problem.

The Phoenix schools would not know what doubling the per student spending rate might do for the achievement of their students. They, along with the rest of the states schools, rank 49th in per student spending next to the bottom! This is according to the Quality Counts 2004 study by Education Week.

Currently, the Arizona legislators have the opportunity to correct this grossly unjust oversight but are still in debate. The state has a $1.2 billion budget surplus to spend. The Phoenix schools and the other schools in Arizona are in dire need of this money, which is a nationally known fact. The state is becoming a laughing stock over its neglected educational system. Yet, those in the State Capitol are debating between using the surplus for education funding, in support of biosciences, or property tax cuts. All areas are important to the state and in need of funding relief; however, as in the Phoenix schools, if you do not graduate students prepared for college and the workplace, the states economy will suffer in the future.

Business groups see education in the Phoenix schools as top priority. They know that to survive in business today, and especially tomorrow, it takes qualified job candidates with college degrees and the skills to succeed. Otherwise, the businesses will not succeed. Historically in such situations, businesses eventually relocate to areas that graduate higher-skilled high school graduates, knowing that many will return to the area after college. Currently, Phoenix schools, along with the remainder of the state, are consistently ranked at the bottom nationally for the number of students who graduate from high school. Is it any wonder that businesses are concerned.

Many parents seek alternatives to the Phoenix schools, unhappy with the school system. Many home school their children. Some move to specific areas in order to enroll their children into better schools. For those parents who can afford it, their children attend private schools. The majority, however, are stuck in the Phoenix schools, because they cannot afford to do otherwise.

The legislature will definitely increase spending for education this year for K-12, of which the Phoenix schools will receive their portion. With all the attention on per student spending, how can they do otherwise? Yet, will the allocated increase be enough? Without quality education in the Phoenix schools, many of the youth of Phoenix will be destined to low-wage, dead-end jobs with little opportunity to succeed. Very few will even consider college, let alone fulfilling such a dream.
