An old controversy has 'flared up' among scientists who are still trying to explain the high temperature of the Sun's corona. The problem is that the temperature of the thin outer atmosphere of the Sun (the corona) is as high as 2 million degrees F while the surface (photosphere) is only 10,000 F and the region immediately above, (the chromosphere)

Sometimes I feel sorry for the local weatherman. He or she has to get in front of the television camera every day and give forecasts up to a week in advance knowing full well that those forecasts are apt to be wrong. Here's why. Weather forecasting is based on computer modeling and these computer models are based on two things; the physics and

Technology is playing an ever-increasing role in our daily lives. From the cars we drive, the homes we live in and the places we work and learn, we are faced with technology by the bucket load, aiming to improve efficiency and encourage competitiveness on a modern scale. The fact of the matter is, today technology is an irretrievable constant in

You've gone to the store, and seen a telescope. It is the only telescope available, and says you can see the entire universe. It looks so good, that NASA's Hubble Space Telescope doesn't look like it can compare to this 'best telescope in the world'! There are some things to consider before buying your first telescope. * Buying Telescope Myths

With all of the different flow meters that there are to choose from, it is no wonder that people tend to become so frustrated when they are sitting down and trying to determine which type of flow meter they actually need; there are variable area flow meters, positive displacement flow meters, nitrogen flow meters, portable flow meters, oil flow met

Do you have the right tools for the job? How about materials? Here are a few tips on practical projecteering Supervision is required for experiments involving animals. If your tools are inadequate for building a project, check your high school shop. Chances are they will have everything you need including power tools and special equipment t

Amid the much hype being created about this alternative fuel, sceptics are asking if it will be promoted at the cost of edible oils. For many years now, many environmentalists and energy experts have been projecting bio-fuel as an ideal solution for the energy crunch and environmental pollution bedeviling the overcrowded and overheated planet Ea

After all the buzz about the new water for fuel technology, which actually is a concept that was first discovered more than two centuries ago, way back in 1800 as a matter of fact. I wanted to take a close look at some important facts. With all the ads and websites talking about using hydrogen Fuel abstracted from water and ethanol, which was th

In three to ten years, expect the major announcement this country has been waiting for -- that artificial life has been officially created. Whether one is vehemently opposed to such technology, or believes it the greatest scientific breakthrough of the modern era, get ready. Scientists in the obscure field of "wet artificial life" are making st

It took years of research before the solar oven was eventually introduced to the world. It is low-cost, it is long-lasting and it is highly efficient. The solar oven was designed to stand almost any weather condition and it is also energy efficient. The temperatures the solar oven reach are incredible and enough to produce meals that are wonderful

The helicopter is, together with the airplane, the most important invention of the 20th century's aeronautical industry. People have fantasized flying for millennia now. As early as Leonardo da Vinci, the genius who drew a sketch of a manually piloted helicopter, the concept was around. The first modern helicopter was built much later though, in th

There are many airplane parts that do not worry me too much. But all matters and parts related to safety better be safe. And instead of being paranoid, I choose to be informed. Today I am going to introduce you to aeroplane parts. Knowledge and familiarity should clear some apprehensions that ignorance might create. We have all seen a plane.

You can find many uses for a telescope camera, if you look far enough. Indeed, telescopes themselves have been around for a long time, shedding light on the mysteries that are above us. For years and years, people have been using telescopes to record the night sky. In the past, this recording was done with a pen and paper, and people would draw wha

We earthlings love to look up at the moon. So much does the moon enamor us; we write movies, songs and poems by the droves that contain the name of the earth's super satellite. A case in point is the fact that one of the biggest selling record albums of all time is Pink Floyd's "Dark Side of the Moon." For all its romance inspiring awesomeness

Wikipedia describes UV (Ultra Violet) Light as electromagnetic radiation with a wavelength shorter than that of visible light but longer than soft x-rays. It is called ultra violet because the spectrum consists of electromagnetic waves with frequencies higher than those that humans identify as the colour violet. Below are 46 fascinating facts rel
