Solar power technologies, the harnessing of the renewable energy of the sun for our electrical power, include the use of either photovoltaics or implementation of passive solar heating. Lets take a look at each. Photovoltaics PV for solar power are solar cells whose purpose is to convert the light from the sun directly into electricity. These P

The dinosaurs have always thrilled humans and held them spell bound for their variety of species from small to huge and gigantic dinosaurs. They are no more in existence but their presence is still felt in the museums, books and films. The dinosaurs first appeared on this earth around 230 million years ago and showed their existence for complet

Geometry, the only mention of it can bring an itch to the fingers of many who love the subject. However it can also bring spasms to the stomachs who dislike it. Whatever is the case, but in fact, Geometry is one subject that equally fascinating and practical. That is why; geometry stands out to be one of the most popular and equally important subje

Bulk metallic glass, a.k.a. amorphous metal, appears to have a very bright future. Being twice as strong as titanium, tougher and more elastic than ceramics, and having excellent wear and corrosion resistance makes them attractive for a variety of applications. It can even be cast in a mold to near net shapes. Conventional Metals In an ordin

Below are some quick introductions into two scientific terms, highly simplified to help you understand them to a better degree. Absolute Configuration This is a way of denoting the absolute structure of an optical isomer. Two conventions are in use. The D-L convention relates the structure of the molecule to some reference molecule in the cas

Those who hate to fly would not be thrilled to hear about one of the newest ways to travel: spaceship. It all began back in 1985 when the first non-astronaut, Jake Garn, flew on Discovery from April 12th to April 19th as a specialist. Later, on April 28th, 2001 Dennis Tito became the first space tourist when he paid a fee to visit the Internati

Human Growth Hormone (HGH) or Somatotrophin is a protein which helps in growth and cell production in animals and humans. It is the hormone which is made naturally in the pituitary glands of humans. The pituitary gland is deep inside the brain just behind the eye. The hormone is made in the body throughout a persons life but the development of this

One of the most exciting and controversial phenomenon in medicine is spontaneous healing. There are thousands of cases of spontaneous healing from many diseases including cancer. According to research conducted at the Institute of Noetic Sciences (IONS) there have been over 3,500 well-documented cases of spontaneous healing. At present there is no

Understanding about the positive displacement flow meter is an incredibly important matter, and most people actually do not even know what a displacement flow meter is to begin with. What a positive displacement flow meter does is it measures the volume or flow rate of a moving liquid or gas, and it does this by dividing the media into fixed, meter

When you think of Avionics think of the amazing control systems and monitoring mechanisms that keep aircraft afloat in the skies. Very simply, Avionics is equal to Aviation plus Electronics. It is a play on words; in the 40's most of the operating systems which were involved in aircrafts were either mechanical, electric, radio-frequency based,

Movies like Deep Impact and Space Cowboys presented stories about major meteorite impacts on Earth. These movies discussed what might happen if a meteor or asteroid was discovered on a collision course with Earth. Both movies involved space ships going to the asteroid and trying to blow it up or deflect it with nuclear weapons. In the end, mankind

Stumped for a good idea? Interesting project possibilities can be found almost anywhere you look. During late fall and early winter of every year, at thousands of high schools across the country, hundreds of thousands of prospective science fairers buckle down to the task of selecting a project. Finding a suitable theme or topic is the first and

An emblem is a visual representation that defines an idea, thought, or an entity. It's synonymous with the words symbol and sign. They are written everywhere in our daily lives. Around the world, it is universally accepted that the symbol of a heart represents love; or that a peace sign tattooed on an arm or posted on a wall is a visual reminde

Our home planet Earth is the third planet out from the Sun and is the largest and densest of the four inner planets. Earth is also the first planet out from the Sun that has a Moon and is the only planet in our Solar System where liquid waters exists in large quantities on the surface. It is generally agreed that the existence of liquid water is th

Using something as complex as a thermal mass flow meter may be enough to scare many of us back to the indoors to worry about making dinner and going to sleep, but the fact is that using this piece of equipment is actually very simple and can be detrimental to learning more and more about our industrial output. Using a thermal mass meter is basic
