String Theory is currently one of the most important theories in fundamental physics, with applications to a variety of subfields including black holes and cosmology, nuclear physics others. This episode is an introduction to the core ideas of the field, as well as to some of its applications. Our guest is Alexander Westphal of Germany’s particle physics lab DESY. He does a wonderful job of introducing the very abstract topic in a way that could be understood by non-physicists, at least to some degree.
This episode is a conversation with Volker Springel about the Millenium Simulation, which at the time was the largest simulation of the growth of cosmic structure, including a detailed model for the formation of galaxies and supermassive black holes. In the episode we talk about the physical/cosmological background, the simulation process and approach as well as some details about the hard- and software.
