Psychology is not really a sicence in my mind because it's only really been recently they have indulged themselves in any form of experimentation.I think we might need to get a Neurologist and a psychologist together to have a debate.
Actually ...... you are skimming somewhere near the truth Ainsley but I'd beg to differ when you look at what the likes of what Einstein, Bohr, Heisenberg and Newton discovered .... I agree the mathematics of what they discovered came along shortly afterwards to formalise their new thinking but their thought processes were not purely mathematical, they were scientific.I would class intelligence as 'deeper understanding'. There are a lot of people who can retain facts and regurgitate them when needed but can never truly apply them.
Over physicists, I would class mathematicians as the brightest. Most headway in any field of science is brought on by its purest common language.....maths. Sure, physicists get all the glory but behind it all is a maths geek....and I use 'geek' as a term of endearment.
However there is that quote from someone along the lines of being a professor - 'the more you know about less and less'
I like to work in metaphors/pictures, I have a visual mindOddJob, send me some of the stuff you're smoking please mate, I'll PM you my address!
