Div Grad Curl and All ThatI found this lovely book in Folyes Book Shop in London. Folyes, especially the old one is one of my favorite book shops in the world. In fact it is one of my favorite places in the world to be full stop!
Well I was in the physics section one day minding my own business when a rather strange but friendly man started chatting with me.
"So you like Physics eh? What do u like about it and why?" "Uh, I am really trying to wrap my head around General Relativity, I am fascinated by the theory but can't quite wrap my head around all the math...", I replied. "Well have a look at Div Grad Curl", he said and proceed to nimbly hop round the shop till he had actually found me a copy. "It worked for me", he said, as he hand over the small red curious book.And that's how I got it.
