Lambert’s proofs that e and pi are irrational

May 10, 2016

The last few weeks I’ve spent revising, in response to an emailed comment, a pdf (revised version here) I attached to a 2010 post about Lambert’s proofs. I’ve started a new page, ‘Rational or Irrational?’, in which I’ve put a link to the revised version and I will add to this page over time material from posts I made some time ago about Hermite’s, Niven’s and Apéry’s work on irrational numbers.
