A Theory With Mathematical Beauty

A Physical Law Must Possess Mathematical Beauty.

I Admired Bohr Very Much. We Had Long Talks Together, Long Talks In Which Bohr Did Practically All The Talking.

Scientific Progress Is Measured In Units Of Courage, Not Intelligence.

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.

I Should Like To Suggest To You That The Cause Of All The Economic Troubles Is That We Have An Economic System Which Tries To Maintain An Equality Of Value Between Two Things, Which It Would Be Better To Recognise From The Beginning As Of Unequal Value.
