Natures elemental puzzles—from eccentric particles to dark matter to why our universe is expanding so swiftly—are what Hitoshi Murayama lives to solve. After receiving his Ph.D. in theoretical physics from the University of Tokyo in 1991, Hitoshi went on to become a senior staff member at Lawrence Berkeley National Laboratory and The MacAdams Professor of Physics at the University of California, Berkeley. His clarity of thought, collaborative style, enthusiasm and vision has inspired his fellow scientists and the public. In 2007, Hitoshi was named the founding director of the University of Tokyos Institute for the Physics and Mathematics of the Universe. The institutes goal: use the synergistic perspectives of mathematics, astronomy, and theoretical and experimental physics to reveal how the cosmos was formed, how it runs, and why we exist. http://tedxtokyo.com/tedxtokyo-2010/program/hitoshi-murayama/ About TEDx, x = independently organized event In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.* (*Subject to certain rules and regulations)
