Opis

A lively and erudite introduction for readers with a background in undergraduate mathematics but no previous knowledge of physics.

Recenzje

'The text has many exercises and sixteen (!) appendices from which one can learn quite a bit. This shows the dedication of the author to the subject and his wish to share his knowledge with others. The book hits the point between mathematics and physics where the first is not too abstract and the second not too phenomenological … In short, the book is exceptional and might set standards.' Marek Nowakowski, MathSciNet
