Tom has that rare gift of being able to communicate and explain difficult concepts in a way that is engaging, informative and fun… and he does it all with an enthusiasm that is infectious. His memorably colourful explanation of the mathematics and mechanism of the famous Enigma machine, which I have often enjoyed, is something that I can only aspire to. His students are fortunate indeed to have been taught by him.
