I will review some recent joint work with Francis Brown on the structure of genus zero amplitudes in string theory. Inspired by conjectures made by physicists, we constructed motivic versions of the amplitudes and used them to prove a relation between the amplitudes associated to open strings and those associated to closed strings. They show up as two variants of a universal object on the moduli space of genus zero curves with marked points.
