Oh thank you. That does sound interesting but I'm absolutely not allowing myself any reading material until I've gotten through these maths books and I have 9 currently to get through. I have to sit an exam in advanced math in June to get into theoretical physics in September. I only decided to do this at the end of Jan haha and considering I left high school 10 yrs ago and was rubbish at maths then, what I've signed up for is plain crazy
but an interesting little quest so far that has very much engaged me. I may well eat my words in June haha
