A few highlights from lecture yesterday at Nordita, about numerical techniques to evolve magnetic fields in cosmological simulations and (try to) simulate small-scale dynamo amplification.

Message 1. there is no best method for all needs: it depends
Message 2: they all are anyway wrong as they probe a different regime of plasma than is in nature - the best we can do is to hope we can extrapolate results to the right regime.
