Ok so this is kinda wishy washy but I don't know how else to explain this other than I feel like Im missing a critical piece of information as far as fundamental "math" goes. Im highly intelligent and and am a Mechanical Engineering Major who gets all A's, but I feel like Im missing a "foundation." Ive been watching these http://www.youtube.com/watch?v=dW8Cy6WrO94&feature=list_related&playnext=1&list=SP55C7C83781CF4316 videos which is a lectures series on the history of math/algebra/calculus and It is helping somewhat. I know this is a very hard question to answer and I know myself better than any of you of course. However Im curious to know what some of guys think about my desire to have a "ground up" understanding, I was very uninterested on High School and have just recently discovered my geeky/intellectual nature at 26 years old and my life has been completely reinvigorated with a desire to learn anything and everything about anything especially physics and calculus/math/number theory. Sorry to rant but Im very curious to see you guys thoughts on going back to fundamentals! Any book recommendations or comments are highly appreciated!
