These are the show notes for episode 34 of the Travels in a Mathematical World Podcast. 34 is the magic constant of a 4 by 4 normal magic square. More about 34 from Number Gossip. There is a good page on magic squares from markfarrar.co.uk.
This week on the podcast I speak to Dr. Eugenia Cheng from the University of Sheffield who talks about category theory. You can find out more about Eugenia’s work at her website. If you are interested to find out more about category theory, an excellent place to start is to watch Eugenia on TheCatsters YouTube channel. There are an interesting set of slides, “Category Theory for Beginners” by Dr Steve Easterbrook of the University of Toronto and a set of notes “An ABC of Category Theory” by Tom Leinster of the University of Glasgow.
