Amplituhedron

This is where I’ll talk about higher-dimensional generalizations and linearizations of hard problems to make them simpler, easier, and faster to analyze or solve. The amplituhedron is a good example because it takes a previously challenging problem of calculating the particle interactions and reduces it to a geometry problem. This concept is the central idea that I like (and hope to see more of) wherein geoemetry and geometrical/dimensional structure is shown to have a direct application in and relationship with the physical world and the analysis of it that we do.
