The Methods Of Theoretical Physics Should Be

A Great Deal Of My Work Is Just Playing With Equations And Seeing What They Give.

When [erwin Schrödinger] Went To The Solvay Conferences In Brussels, He Would Walk From The Station To The Hotel Where The Delegates Stayed, Carrying All His Luggage In A Rucksack And Looking So Like A Tramp That It Needed A Great Deal Of Argument At The Reception Desk Before He Could Claim A Room.

No. I Had Successfully Solved The Difficulty Of Finding A Description Of The Electron Which Was Consistent With Both Relativity And Quantum Mechanics. Of Course, When You Solve One Difficulty, Other New Difficulties Arise. You Then Try To Sove Them. You Can Never Solve All Difficulties At Once.

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

It Is Quite Clear That Beauty Does Depend On One's Culture And Upbringing For Certain Kinds Of Beauty, Pictures, Literature, Poetry And So On...but Mathematical Beauty Is Of A Rather Different Kind. I Should Say Perhaps It Is Of A Completely Different Kind And Transcends These Personal Factors. It Is The Same In All Countries And At All Periods Of Time.
