These are the show notes for episode 16 of the Travels in a Mathematical World Podcast. 16 is the only number of the form x^y=y^x with x and y as different integers, being both 2^4 and 4^2. More about the number 16 from Number Gossip.

I visited the University of Greenwich last summer and spoke with Professor Chris Bailey, who is working on the conservation of the Cutty Sark project. You can read more about the Cutty Sark at the Cutty Sark website. There is an article about Chris’ work on the Cutty Sark from the Independent, read “How Greenwich University is helping to rebuild the Cutty Sark“. You can read a good introduction with plenty of suggestions for further readings on the Wikipedia page for Reliability engineering.
