"The methods of theoretical physics should be applicable to all those branches of thought in which the essential features are expressible with numbers."
~Paul Dirac. 

Theoretical physics is the tool by which we will define the parametres of the universe. Underlying which is the fundamental description provided by mathematics. Mathematics comprise theoretical physics and without out it, we'd be lost. 

I am about to get my graduates degree in theoretical physics. I do not have many friends and so my presence on this site is to allow myself an avenue down which to channel thoughts, in a way that is social.
