A Physical Law Must Possess Mathematical Beauty.

A Theory With Mathematical Beauty Is More Likely To Be Correct Than An Ugly One That Fits Some Experimental Data.

If We Are Honest - And Scientists Have To Be - We Must Admit That Religion Is A Jumble Of False Assertions, With No Basis In Reality.

I Learnt To Distrust All Physical Concepts As The Basis For A Theory. Instead One Should Put One's Trust In A Mathematical Scheme, Even If The Scheme Does Not Appear At First Sight To Be Connected With Physics. One Should Concentrate On Getting Interesting Mathematics.

I Think It Is The General Rule That The Originator Of A New Idea Is Not The Most Suitable Person To Develop It, Because His Fears Of Something Going Wrong Are Really Too Strong... At Age 69.

I Do Not See How A Man Can Work On The Frontiers Of Physics And Write Poetry At The Same Time. They Are In Opposition.
