Associahedra Memories
30 November 2018
When I spoke about associahedra and scattering amplitudes at ANU’s Morgan Phoa Workshop in 2006, nobody else was thinking along those lines, except Francis Brown, who was writing up his beautiful thesis. There was a mixed reaction from the mathematicians in the audience. Ross Street, as always, found the connection between category theory and modern physics fascinating. Michael Batanin was way ahead of everyone else with his new work on operads and higher dimensional ordinals. One algebraic geometer complained that he was not at all interested in physics, and I was far too modest at that time to tell him that he should pay attention. So many memories!
