Neumann, To A Physicist Seeking Help With

The Emphasis On Mathematical Methods Seems To Be Shifted More Towards Combinatorics And Set Theory - And Away From The Algorithm Of Differential Equations Which Dominates Mathematical Physics.

The Sciences Do Not Try To Explain, They Hardly Even Try To Interpret, They Mainly Make Models. By A Model Is Meant A Mathematical Construct Which, With The Addition Of Certain Verbal Interpretations, Describes Observed Phenomena. The Justification Of Such A Mathematical Construct Is Solely And Precisely That It Is Expected To Work-that Is, Correctly To Describe Phenomena From A Reasonably Wide Area.

If People Do Not Believe That Mathematics Is Simple, It Is Only Because They Do Not Realize How Complicated Life Is.

Anyone Who Attempts To Generate Random Numbers By Deterministic Means Is, Of Course, Living In A State Of Sin.

Science, As Well As Technology, Will In The Near And In The Farther Future Increasingly Turn From Problems Of Intensity, Substance, And Energy, To Problems Of Structure, Organization, Information, And Control.
