The RSK correspondence is a bijection between permutations (more generally nonnegative integer matrices) and certain pairs of tableaux. I will outline a geometric incarnation of this bijection coming from the representation theory of the general linear group. I will describe the link to the Calogero Moser system of particles on a line and to a conjecture of Bonnafe and Rouquier related to Kazhdan--Lusztig cells of finite reflection groups. This is joint work with Adrien Brochier and Iain Gordon.
