Something a bit different: translations of classic mathematical texts (!)
During his retirement, my father has been able to spend much time indulging his love of mathematics. This included, amongst other impressive endeavours, attending Cambridge at a more advanced age than average to take (and pass!) the Part III of the Mathematical Tripos, often considered one of the hardest taught courses in maths in the world.
Having completed this monumental piece of work, it seemed only proper to share it a little more widely so that other students might benefit from his efforts – and that’s where I come in, since I’m the one with the website. So if you have any passing interest in 19th / 20th century modern algebra, I encourage you to check out Noel Robinson’s translation of “Theory of Algebraic Functions of One Variable”, hosted on this site.
