The International Year of the Light Symposium: Session 3

We are visual beings, and qualities such as “insight” and “vision” describe our understanding well beyond sensory input. Light and more generally, electromagnetic radiation, has dramatically changed our knowledge of the physical world. It is also the source of the oxygen we breathe, the food we eat, and the energy that has powered the world since the beginning of the industrial revolution. Nobel Laureate Steven Chu, Professor of Physics, Professor Molecular & Cellular Physiology, Stanford University, discusses how light will continue to expand our scientific horizons and redefine our daily lives: from the measurement of time, to biology, medicine, and combating climate change.
