I can't understand!

From the book : Surely you are joking Mr.Feynman! ...by Richard Feynman

 

Feynman tells his Sister:  

I can't understand these things that Lee and Young are saying (in their research Paper). Its all so complicated. 

to which his Sister responds : 

No! What you mean is not that you can't understand; but you did'nt invent it

you did not figure it your own way from hearing the clue; 

What you should do is imagine you're a student again - and take this paper upstairs

and read every line of it , and check the equations -

then you'll understand it very easily!

My notes: 

Oh! wow! 

Even Feynman, the noble-prize winning scientist does not understand many things!

So who am I ? if I don't understand, its natural - I don't need to freak out - 

rather Imagine that I am a student again - and get back to the basics : do the calculations myself and seek to understand it!
