[math-fun] A Jewel at the Heart of Quantum Physics

https://www.simonsfoundation.org/quanta/20130917-a-jewel-at-the-heart-of-qua... Physicists have discovered a jewel-like geometric object that dramatically simplifies calculations of particle interactions and challenges the notion that space and time are fundamental components of reality. "This is completely new and very much simpler than anything that has been done before," said Andrew Hodges, a mathematical physicist at Oxford University who has been following the work. --- co-chair http://ocjug.org/
