Description
I will introduce the language of on-shell diagrams for calculating scattering amplitudes via BCFW recursion in $\mathcal{N} = 4$ super Yang Mills theory, and then explain how they can be extended to $\mathcal{N} = 8$ supergravity. I will describe how this approach relates scattering amplitudes to the Grassmannian Gr$(k,n)$, a purely geometric object describing the space of $k$ planes in $n$ dimensions. This link to the Grassmannian exposes a duality between on-shell diagrams and ambi-twistor string theory, and I will present my work in progress in this area.
