• Physics Overview By: Ron Smith2009 - Hi,I want to give brief introduction about Physics.Physics is a natural science. It is the study of matter and its motion through space time and all that derives from these, such as energy and force. Physics is the general analysis of nature, conducted in order to understand how the world and universe behave. Physics is the science of matter and energy and of interactions between the two, grouped in traditional fields such as acoustics, optics, mechanics, thermodynamics, and electromagnetism.
• Aliens, UFOs, Alien Abductions, Close Encounters - Chance or No-chance? By: Andy Chains - I've been a sci-fi fan since before Star Trek's Captain Kirk split his first infinitive ("To boldly go ..") - but I have to doubt if we'll ever encounter any of his intelligent alien friends or even any unintelligent alien microbes.

• Fascinating Facts about Dinosaurs By: David H Urmann - Dinosaurs were believed to have roamed the Earth millions of years ago. It is a dominant species of vertebrate animals whose extinction brought up a lot of questions to scientists until the present day. Dinosaurs used to be the dominant vertebrate animals of our ecosystem. Under the phylogenetic taxonomy, dinosaurs are classified as sole descendants of the most current ancestors of modern birds and Triceratops. It is also suggested that dinosaurs can be classified as the descendants of the most current ancestor of the iguanodon and megalosaurus.
• What Cradle To Cradle Recycling Can Do For Us? By: Michael Arms - We promote and practice the three R's - "reduce, reuse, recycle" to mitigate the disastrous effect of our profligate way of life and frivolous products on nature, after which we sit back, satisfied in the notion that when we go green we're making the right choice. And why not? We've just helped reduce the volume of waste that's going to be dumped into our landfills (or worse, in the oceans), we've done our part in helping protect the environment. But, are we really choosing the best option when we recycle?
• Decoding The MSF-60 UK Radio Time Broadcast By: Dave Evans - The MSF time and frequency broadcast is a radio time signal transmitted from Anthorn, Cumbria in the UK. The signal can be used as an accurate and reliable source of time derived from atomic clocks at the UK National Physics Laboratory. The effective radiated power of the transmitter is 15kW, providing a transmission range of approximately 1000 km. The signal can be received throughout the UK and much of northwestern Europe. It is often used by synchronised clocks and watches and network time servers.
• Is a Plastic Car in Your Future? By: Zach Thompson - Development of plastic cars could rejuvenate the American auto industry. With the recent bankruptcy of Chrysler and the financial problems at the other US based automobile manufacturers; it may be time for the management to take a deeper look at producing cars made of plastic.

This would help stimulate the economy which would increase jobs.
• Glycerol Creation: Reviews In This New Trend In Restorable Energy By: Jo Alesto - Nowadays, the increase in the price of gas is a phenomenon one cannot consider as erratic. It is an occurrence that infuriates the general public. But one which people have to endure, come in terms with, and tighten their belts for them to be able to tide over the situation. The last two decades or so have seen some of the most unusual spikes in the price of gasoline, and consequently, this results to an increase in the cost of other commodities as well. Gasoline and diesel belong to the non-renewable type of energy.
• NASA Lunar Mission Enters the Moon Successfully By: sarte - The Lunar Reconnaissance Orbiter (LRO) has successfully entered orbit around the moon. Engineers at NASA’s Goddard Space Flight Center in Greenbelt, Md., confirmed the spacecraft’s lunar orbit insertion at 6:27 a.m. EDT July23,2009-Tuesday. During transit to the moon, engineers performed a mid-course correction to get the spacecraft in the proper position to reach its lunar destination. Since the moon is always moving, the spacecraft shot for a target point ahead of the moon.
