Well, I had a chance to go through this book titled, "Surely you Are Joking, Mr. Feynman", again after quite a while and it made a great read.
Now, I use Google a lot to acquire whatever I can’t keep in my small head. The question has always been about what needs space and what can be acquired from sources like Google. Professor. Feynman was a freak in every sense. While in Princeton he used to move around various groups like Philosophy and life Sciences. So, he was given a task to related to physics while attending a Biology Class(something he was not working on as his main interest). He was studying nerve impulses in living beings and the creature being studied was a cat. So, he starts his lecture by drawing a picture of a cat and naming a few muscles.
The other students in the class interrupt him saying, we know all that. This is his reply and I have used a similar statement before and you might find it answers a part of the question I talked about earlier.
"Oh," I say, you do? Then no wonder I can catch up with you so fast after you have had 4 years of biology."
They had wasted all their time memorizing stuff like that, when it could be looked up in 15 minutes.
Selective memory rocks.
