Happy Ada Lovelace day! This is the day that bloggers all over the world post about women in science as part of a global day of awareness and appreciation for the (often underreported) role that women play in the sciences.
My contribution is this fantastic presentation by physicist Lisa Randall at the Origins conference in Tallahassee Florida, broadcast last Friday as part of NPR's Science Friday show. Randall is the author of Warped Passages: Unraveling the Mysteries of the Universe's Hidden Dimensions, a popular science book that addresses fundamental questions about the nature of the universe. On this show, Randall explains what an expanding universe is expanding into, the relationship of gravity, magnetism and hidden time-space dimensions, and other mind-benders about the origin of the universe (she also talks a little about the role of women in science).
