In previous work it has been observed that the singularity structure of multi-loop scattering amplitudes in planar N=4

super-Yang-Mills theory is evidently dictated by cluster algebras. In my talk I will discuss the interplay between this mathematical

observation and the physical principle that the singularities of Feynman integrals are encoded in the Landau equations.
