There Are Always More People Who Prefer

I Consider That I Understand An Equation When I Can Predict The Properties Of Its Solutions, Without Actually Solving It.

There Are Always More People Who Prefer To Speak Than To Listen.

The Underlying Physical Laws Necessary For The Mathematical Theory Of A Large Part Of Physics And The Whole Of Chemistry Are Thus Completely Known, And The Difficulty Is Only That The Exact Application Of These Laws Leads To Equations Much Too Complicated To Be Soluble. It Therefore Becomes Desirable That Approximate Practical Methods Of Applying Quantum Mechanics Should Be Developed, Which Can Lead To An Explanation Of The Main Features Of Complex Atomic Systems Without Too Much Computation.

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.

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. In Science You Want To Say Something That Nobody Knew Before, In Words Which Everyone Can Understand. In Poetry You Are Bound To Say ... Something That Everyone Knows Already In Words That Nobody Can Understand. Commenting To Him About The Poetry J. Robert Oppenheimer Wrote.
