191 – String Theory
Guests: Alexander Westphal Host: Markus Voelter Shownoter: Alexander Grote
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.
Once again I forgot to mention those of you (listeners) who suggested questions, so I am doing it here: Stefan Hacker, Brent Knickerbocker, Christopher Schuster and David Liaromatis.
