“What is Color?” was the dominant question submitted by more than 26,000 curious eleven-year olds around the world in this year’s Flame Challenge, issued by the Alan Alda Center for Communicating Science at Stony Brook University. The Challenge asks scientists to answer the chosen question in a manner understandable and engaging to eleven-year olds (past questions were: What is a Flame? What is Time?), and this year, almost 400 scientists responded. The 2014 winners were announced on Sunday.
