Good evening, I am in high school (well we would have called it secondary school but I'm assuming most of you are Americans) in Ireland, I will be a senior (Americanism again.. :p) next year (i.e. finishing in 2011) and I have a keen interest in science (particularly physics) and mathematics, I have represented Ireland at various international.. yada yada yada... I'm looking for a couple of books to supplement my education in the meantime before I go to university etc. What I'm thinking of is: -The Feynman Lectures on Physics. -Euclid's Elements (Not sure about this one, but I've heard it's rather good, any help?) -And maybe a Calculus book, i.e. a big theory/detailed one, as I already know basic inetgral/differential calculus from school and wouldn't mind learning a bit more on this (if this is really necessary or helpful, if it's not please tell me). My main issues are. 1. Do you think this is a good choice? and 2. Which calculus book? (If any), as I have found that many of the classic texts (i.e. Apostol etc.) are ridiculously expensive and I just cannot justify paying that much for a book, however good it is, and any affordable suggestions would be appreciated. Thanks in advance.
