Flame Challenge 2: The Answers Are In
Last year, actor and science advocate Alan Alda and the Center for Communicating Science, sponsored the inaugural Flame Challenge by asking scientists around the world to answer “What is a flame?” so that an 11-year-old could understand. This year, the American Chemical Society and the American Association for Advancement of Science have joined in on the sponsorship, and the question scientists have been asked to answer is, “What is time?”
Nearly 20,000 students from around the world have voted on the hundreds of submissions that made it through an initial screening by trained scientists, and the six best answers–three videos and three written responses–have been unveiled on the Flame Challenge website. The finalists each use unique examples to explain time. Some mention Einstein’s theory of relativity, some go into the details of the space-time continuum, and some rely on time being an invented concept that keeps track of events. One thing mentioned in each entry: time only has one direction and that’s forward.
Registered schools can vote for their favorite answers until May 5. This year, rather than recognizing one overall winner, the best entry for each format will be recognized. That will happen at an event on June 2 at the World Science Festival, in New York City.
