These are the show notes for episode 37 of the Travels in a Mathematical World Podcast. 37 is prime, the number you get if a three digit number having the same digits is divided by its digit sum. More about 37 from Number Gossip.

This week on the podcast we hear from David Mitchell of the University of Edinburgh, who is doing a collaborative PhD between the Schools of Mathematics and Engineering. David talks about his area channel coding and about the links between mathematics and engineering.

You can view slides from an IBM talk on channel coding for an introduction. You can read careers profiles of mathematicians working in engineering on the Maths Careers website, where you can also find advice on taking postgraduate study.
