Science from the Poles:  South Pole Telescope: Getting There & Starting to Build (Webcast)
Running Time:
00:34:45
After years of preparation, scientists from the University of Chicago are making the long journey to the South Pole to begin construction on the new 10-meter telescope. Join us as we talk to scientists at the pole about their long journey, learn about the pre-building of the telescope in Texas last summer; and find out what challenges they face in constructing a major scientific instrument in freezing conditions.

Ancient Writings Revealed:  The Evidence Project Presents: Ancient Writings Revealed! (Webcast)
Running Time:
00:58:32
Watch ancient text revealed and read for the first time in a thousand years! Archimedes was one of the world's greatest scientific and mathematical minds. His thoughts were inscribed on goatskin parchment, but the letters and diagrams were scraped off and written over by Greek monks in the Middle Ages. Now, using an intense x-ray beam generated at Stanford University's linear accelerator, some of the original Greek text will be revealed for the first time in the modern world.
