I Admired Bohr Very Much. We Had

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

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.

A Book On The New Physics, If Not Purely Descriptive Of Experimental Work, Must Essentially Be Mathematical.

As Time Goes On, It Becomes Increasingly Evident That The Rules Which The Mathematician Finds Interesting Are The Same As Those Which Nature Has Chosen.

Mathematics Is The Tool Specially Suited For Dealing With Abstract Concepts Of Any Kind And There Is No Limit To Its Power In This Field.
