Young Man, In Mathematics You Don't Understand

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.

I Am A Little Troubled About The Tea Service In The Electronic Computer Building. Apparently The Members Of Your Staff Consume Several Times As Much Supplies As The Same Number Of People Do In Fuld Hall And They Have Been Especially Unfair In The Matter Of Sugar.... I Should Like To Raise The Question Whether It Would Not Be Better For The Computer People To Come Up To Fuld Hall At The End Of The Day At 5 O'clock And Have Their Tea Here Under Proper Supervision.

All Stable Processes We Shall Predict. All Unstable Processes We Shall Control.

Problems Are Often Stated In Vague Terms... Because It Is Quite Uncertain What The Problems Really Are.

The Total Subject Of Mathematics Is Clearly Too Broad For Any Of Us. I Do Not Think That Any Mathematician Since Gauss Has Covered It Uniformly And Fully; Even Hilbert Did Not And All Of Us Are Of Considerably Lesser Width Quite Apart From The Question Of Depth Than Hilbert.
