Denis Weaire gave a talk of the "compare and contrast" variety, on:
Two Natural Philosophers: Kelvin and Fitzgerald.
Most of the material can be found in "The Value of Useless Studies", Europhysics News, September 2002, 170-3, and in "Creators of Mathematics: the Irish Connection", University College Dublin Press (2000)
One for our archivists?
Denis Weaire recently found a large physics textbook (Licoes de fisica)
in Portugal, circa 1845 (judging by content) but with no title page.
Any idea who might be the author?
Answers to the editor please.
