The Simons Center for Geometry and Physics in Stony Brook is going to be running the program Physics and Mathematics of Scattering Amplitudes during the fall 2013 semester. It started last week with talks by Henriette Elvang and Johannes Henn. Sadly, I am going to miss the talks in person. But thankfully, there are going to be videos of most of the talks. The talks from last week can be found here and here.
