He is best known for his eponymous laws of planetary motion, codified by later astronomers based on his works "Astronomia nova", "Harmonices Mundi", and "Epitome of Copernican Astrononomy". They also provided one of the foundations for Isaac Newton's theory of universal gravitation. During his career, Kepler was a mathematics teacher at a seminary school in Graz, Austria, an assistant to astronomer Tycho Brahe, the court mathematician to Emperor Rudolf II, a mathematics teacher in Linz, Austria, and an adviser to General Wallenstein. He also did fundamental work in the field of optics, invented an improved version of the refracting telescope (the Keplerian Telescope), and helped to legitimize the telescopic discoveries of his contemporary Galileo Galilei. Kepler lived in an era when there was no clear distinction between astronomy and astrology, but there was a strong division between astronomy (a branch of mathematics within the liberal arts) and physics (a branch of natural philosophy). • http://en.wikipedia.org/wiki/Johannes_Kepler .

Stephen Hawking - We must colonize space in order to survive
Note: I edited this video, here is the full 10mins. Stephen Hawking: Asking big questions about the universe http://www.youtube.com/watch?v=xjBIsp8mS-c http://www.ted.com In keeping with the theme of TED2008, professor Stephen Hawking asks some Big Questions about our universe -- How did the universe begin? How did life begin? Are we alone? -- and discusses how we might go about answering them. PLEASE SUBSCRIBE TO: http://www.youtube.com/user/TEDtalksDirector "Since, in the long run, every planetary civilization will be endangered by impacts from space, every surviving civilization is obliged to become spacefaring--not because of exploratory or romantic zeal, but for the most practical reason imaginable: staying alive... If our long-term survival is at stake, we have a basic responsibility to our species to venture to other worlds." Carl Sagan, Pale Blue Dot, 1994 "We need the stars... We need purpose! We need the image the Destiny [to take root among the stars] gives us of ourselves as a purposeful, growing species. We need to become the adult species that the Destiny can help us become! If we're to be anything other than smooth dinosaurs who evolve, specialize and die, we need the stars.... When we have no difficult, long-term purpose to strive toward, we fight each other. We destroy ourselves. We have these chaotic, apocalyptic periods of murderous craziness." Octavia Butler, Parable of the Talents, 1998 "I don't think the human race will survive the next thousand years, unless we spread into space. There are too many accidents that can befall life on a single planet. But I'm an optimist. We will reach out to the stars." Stephen Hawking, interview with Daily Telegraph, 2001 "The dinosaurs became extinct because they didn't have a space program. And if we become extinct because we don't have a space program, it'll serve us right!" Larry Niven, quoted by Arthur Clarke in interview at space.com, 2001 "In time, [a Martian] colony would grow to the point of being self- sustaining. When this stage was reached, humanity would have a precious insurance policy against catastrophe at home. During the next millennium there is a significant chance that civilization on Earth will be destroyed by an asteroid, a killer plague or a global war. A Martian colony could keep the flame of civilization and culture alive until Earth could be reverse- colonized from Mars." Paul Davies, The New York Times, 2004 "We must turn our guns away from each other and outwards, to defend the Earth, creating a global and in space network of sensors and telescopes to find asteroids that could destroy our planet and create the systems to stop them. It makes no sense to dream great dreams while waiting to be hit by a train." Buzz Aldrin and Rick Tumlinson, Ad Astra Online, 2006

Universe 114 Beyond Big Bang 17 Copernicus
The History Channel Australia & New Zealand The Universe : 1/14 Beyond The Big Bang : 1/7 Copernicus Learn about Copernicus' theories of a sun-centered universe. --- It all began inside a violent, blinding explosion that threw everything into chaos. Ever since, our greatest thinkers have peered into that chaos in search of order, logic & the answers to where we began. As earlier generations learned to decipher the cosmic clues of how we came to be, we stepped from revelation to revelation; epiphany to epiphany. Aristotle told us the world was round. Ptolemy conceived of a system of planets, stars & sun. Copernicus placed the sun at the center of this system. Galileo confirmed it. Newton explained what held it all together. Einstein offered insight into what fueled it. Hubble proposed it started with a "Big Bang". Our search for answers has shaped how we have evolved as thinking creatures. The Big Bang is the history of why & how we think about who & what we are. We'll contemplate how various cultures believe the world began & how it will all end...& what comes after. & for the first time, we'll be able to see what it might have all looked like, sitting in God's front row seats. Using unprecedented cutting edge animation, The Big Bang will recreate that amazing moment when everything started. With interviews from the world's leading physicists, engineers & historians we will employ every storytelling tool to make complex & confusing ideas clear, exciting & dramatic. Recreations, visual metaphors & first-person accounts will explain concepts like: the formation of galaxies, the existence of other dimensions & the idea of a parallel universe. The Big Bang will pose one of history's greatest questions, Where do we begin? --- http://www.thehistorychannel.com.au

2007© As Seen On Television (US) Season 1 Episode 14: Beyond the Big Bang SUMMARY: The universe began with a massive expansion, billions and billions of years ago, and it continues to expand with every passing second. The idea that the universe, and man's very existence, began with a "Big Bang" is no longer a topic of debate among most scientists--it is essentially taken as fact. How has man come to this conclusion, and how has our knowledge evolved so that we can recreate the very first seconds of our universe and all that has developed since? Interviews with the world's leading physicists and historians are woven together with animated recreations and first-person accounts to explain concepts such as the formation of galaxies, the creation of elements and the formation of Earth itself.
