Charlie tells us about an unexpected lesson in his audio diary. Patrick talks a little about his placement at MIT Haystack telescope. Thomas worries about how to teach when there is no practical or demo to be done.

Charlie’s audio diary kicks off the podcast, telling us how he has not taught forces at all yet as he had to finish off the induction topic. Thomas then gets excited about the water vapour spotted on a planet 110 light years away from Earth. Amazing precision! Patrick then plays us the interview with Colin Lonsdale from the MIT Haystack observatory. Patrick did a placement there over the summer. Thomas then talks about teaching without practicals and demos and gets some advice from Patrick before deciding it is too big a topic; it needs a whole podcast. At the end of the episode we talk about Fermi questions and estimating and introduce a new Ways to teach… episode.
