This evening I was wondering how our brain can comprehend this complex universe under the mathematical and philosophical way. These scientific methods involve people being able to speculate and hence learn on the basis of mistakes made by others. Thats why communication is so so important: you do not end up re-inventing the wheel!
I did some nice and extensive study of General Theory of Relativity (GTR) when I was Master's student in Tribhuvan University in Nepal. Today, after finding the Original Manuscript by Einstein on Relativity, I was equally amazed on its simplicity and compactness.
This is an awesome paper: No doubt!
In the paper, he starts from very basic formulation of the theory and justifies his theory with compelling examples. WOW!!!
Of course, you will need some background of mathematics but it is real fun.
The paper which revealed the fact that "matter tells space how to bend; space tells matter how to move" can be found here ...
If you are further interested, you can contact Prof. UdayRaj Khanal in Tribhuvan University. (He was my Thesis supervisor in M.Sc., Physics)
