Abstract: I describe the connection between scattering amplitudes in the planar N=4 SYM theory and the Amplituhedron, geometric space which generalizes convex polytopes to Grassmannians. The tree-level amplitudes and loop integrands in this theory can be then calculated as differential forms with logarithmic singularities on the boundary of this geometry. In this picture the physics problem of particle scattering is translated to the non-trivial math problem of triangulations.
