In 2012 actor Alan Alda started a competition in which scientists are asked to explain by whatever means a designated phenomenon or concept to 11 year olds. The explanations are judged by students whose schools are participating in the competition worldwide some 26,000 students so far. This challenge was first introduced to PF in 2012 but has not been followed since. The challenges so far have been What is: A Flame, 2012 Time, 2013 Color, 2014 Sleep, 2015 Sound,2016 This year the challenge is Da Da "What is Energy?" Apparently Mr. Alda remembering an unsatisfactory explanation to his question as an eleven year old student, What is a flame? spurred him to initiate this program. His interest in science and its impact on our lives is exemplified in his Center for Communicating Science In a interview in Australia during its National Science Week he talked about his interest in science and the necessity of explaining it effectively to the general public. I'm sure that there is sufficient talent in the Physics Forum to give it a shot.
