These are the show notes for episode 20 of the Travels in a Mathematical World podcast.In a game of chess both players have 20 first moves from which to choose. More about 20 from Number Gossip.

For episode 20 I visited the University of Greenwich and met Professor Choi-Hong Lai, who talked through some applications of fluid dynamics. The Wikipedia page on fluid dynamics seems fairly readable as an overview. If you’re in a university your university library will hold introductory books on fluid dynamics. You can find further information about Choi-Hong’s research on his website.
