Origin of the Solar System - Motion of Planets - Sun-Centered Vs. Earth-Centered Solar SystemCarl Sagan brings us the Cosmos, everything that ever was and ever will be, in an approach that is easily accessible even for those of us that are not science wizards. This series covers everything from the history of astronomy, the challenges it faced at its creation, how the universe was created and how it all might end, to the evolution of life on Earth, and the nature of the human brain.First aired in 1980 as a 13 part series, it has been broadcast in 60 countries and has been seen by an estimated 500 million to 1 billion viewers worldwide.The series was awarded an Emmy and a Peabody Award.http://www.carlsagan.com/These clips are modified from their original version; they have been updated and revised exclusively for youtube.

Includes about 100 beautiful photos taken from various space probes and the Hubble Space Telescope. Seattle Creation Conference, 2006.Spike clearly disagrees with the Big Bang Theory, as do I. However, while he would propose creation in seven 24-hour days, I believe we live in an electric universe.

Ralph C. Merkle is a pioneer in public key cryptography, and more recently a researcher and speaker on molecular nanotechnology and cryonics.Molecular nanotechnology is the concept of engineering functional mechanical systems at the molecular scale. An equivalent definition would be \"machines at the molecular scale designed and built atom-by-atom\". Divided in 3 parts. Enjoy. [المزيد] [مختصر]

A fun project for me and my son to build. We were inspired by two solar motors on display by Tom K. at the 2007/08 First Lego League state tournament in Illinois. We included the levitation after watching http://youtube.com/watch?v=N3NU22KxDaQ, details at http://mtinfopage.com/mendocin.htm. Special thanks to Tom for providing guidance. All parts, besides the legos, came from Radio Shack [المزيد] [مختصر]
