Bethany Cobb, a UC Berkeley postdoctoral fellow, explains Edwin Hubble's discovery that the universe is constantly expanding. She describes how galaxies are free to move through space, claiming in a few billion years Earth will "slam into the Andromeda Galaxy." ----- Learn about the great astronomy pioneer Edwin Hubble and how his use of a 100-inch telescope at the Mount Wilson Observatory in California not only resolved the "Great Debate" over the scale of the universe but also provided radical evidence that the universe is expanding. - Commonwealth Club Bethany Cobb is a National Science Foundation Astronomy and Astrophysics Postdoctoral Fellow at UC Berkeley. She received her Ph.D. at Yale University for research on massive stellar explosions called gamma-ray bursts. She is dedicated to sharing her love of astronomy with others and is the astronomer for The Old Farmer's Almanac.

He pioneered exobiology and promoted the Search for Extra-Terrestrial Intelligence (SETI). He is world-famous for writing popular science books and for co-writing and presenting the award-winning 1980 television series "Cosmos: A Personal Voyage", which has been seen by more than 600 million people in over 60 countries, making it the most widely watched PBS program in history. A book to accompany the program was also published. He also wrote the novel "Contact", the basis for the 1997 Robert Zemecki's film of the same name starring Jodie Foster. During his lifetime, Sagan published more than 600 scientific papers and popular articles and was author, co-author, or editor of more than 20 books. In his works, he frequently advocated skeptical inquiry, secular humanism, and the scientific method. http://www.carlsagan.com .

The Power of Doubt 4/6 (Science and Islam - Episode 3 of 3) By ISLAMIC0NTENT Part-5; http://www.youtube.com/watch?v=JI187i... Physicist Jim Al-Khalili tells the story of the great leap in scientific knowledge that took place in the Islamic world between the 8th and 14th centuries. Al-Khalili turns detective, hunting for clues that show how the scientific revolution that took place in the 16th and 17th centuries in Europe had its roots in the earlier world of medieval Islam. He travels across Iran, Syria and Egypt to discover the huge astronomical advances made by Islamic scholars through their obsession with accurate measurement and coherent and rigorous mathematics. He then visits Italy to see how those Islamic ideas permeated into the West and ultimately helped shape the works of the great European astronomer Copernicus, and investigates why science in the Islamic world appeared to go into decline after the 16th and 17th centuries, only for it to re-emerge in the present day. Al-Khalili ends his journey in the Royan Institute in the Iranian capital Tehran, looking at how science is now regarded in the Islamic world.
