Summary
In the sixties and seventies of the last century physicists developed procedures to renormalize infinities appearing in quantum field theory. We explain recent work of Connes-Kreimer and Connes-Marcolli, giving a conceptual understanding of these procedures and indicating unexpected links to number theory.
