A Realizability Topos is a topos based on a certain abstract notion of computation. Geometric morphisms of realizability toposes provide an interesting way of comparing these notions of computation. In my talk we will discuss some long-known results as well as some more recent developments in this area. The talk should be enjoyable for any interested student as well as dyed-in-the-wool topos theorists.
