Nobel Laureate Ahmed Zewail: "Light and Life" plenary talk at International Year of Light kickoff

Ahmed Zewail plenary talk at UNESCO headquarters in Paris on 19 January 2015.
Light was an integral part of the creation of the universe. For millions of years, light has defined the life of homo sapiens. Through photosynthesis, light has given us food, energy, and the atmosphere. Using light we communicate information, see planets and moons far from us in the heavens, and see the microscopic objects -- cells and bacteria -- our naked eye cannot resolve. Our life becomes invisible without light. Where does light get this transcending power? spie.org/x11233...
