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.

In this program, he describes how new model organisms are established for studying basic physiology, recounts his reaction to seeing Watson and Crick's DNA model for the first time, and offers advice to young scientists just starting out.
