Newswise — Math: does it explain existence, or is it really just a tool of the brain? This isn't a curiosity; it's a deep and powerful question. According to many astrophysicists, math is at the heart of understanding our universe - and may even one day be the key to explaining our existence. But now neuroscientists are finding evidence that math may actually be a concept developed by the brain - a way for us to make sense of the natural world. So which is the truth? Or is there a middle ground?

On Aug. 7, Noon-12:30 PDT, three leading scientists - two neuroscientists and one astrophysicist -- will answer your questions about this debate. Join us for a special Google Hangout with neuroscientists Brian Butterworth and Rafael Núñez, and astrophysicist Max Tegmark. To submit your questions, email to [email protected] or post on Twitter with hashtag #KavliLive.

PARTICIPANTS- BRIAN BUTTERWORTH - Emeritus Professor of Cognitive Neuropsychology at the Institute of Cognitive Neuroscience at University College London; - RAFAEL NÚÑEZ - Professor of Cognitive Science at the University of California, San Diego and member of UCSD's Kavli Institute for Brain and Mind; - MAX TEGMARK - Professor of Physics at the Massachusetts Institute of Technology, and member of MIT's Kavli Institute for Astrophysics and Space Research.

Moderator BRUCE LIEBERMAN is a freelance journalist with more than 20 years of experience in the news business. Along with The Kavli Foundation, he has written for Scientific American, Smithsonian Air & Space magazine, and Nature about a variety of science topics.
