Rich Muller, a Berkeley Lab physicist, discusses Nobel laureate Luis Alvarez and colleagues’ 1979 discovery that an asteroid impact killed the dinosaurs. He also discusses what scientists have learned in the subsequent 27 years. Alvarez’s team detected unusual amounts of iridium in sedimentary layers. They attributed the excess iridium to an impact from a large asteroid. Series: "Lawrence Berkeley National Laboratory " [Science] [Show ID: 11829]

Go behind the famous equation with Hitoshi Murayama. This famous equation, part of the theory of relativity set forth by Einstein, changed our understanding of nature at the most fundamental level. The fascinating story of energy (E) and mass (m) is still evolving a century since Einstein as we understand more of where they come from, how they shape the universe, and the missing pieces of the universe: Dark Matter and Dark Energy.
