Unless You Stake Your Life, Life Will

It Seems Sensible To Discard All Hope Of Observing Hitherto Unobservable Quantities, Such As The Position And Period Of The Electron... Instead It Seems More Reasonable To Try To Establish A Theoretical Quantum Mechanics, Analogous To Classical Mechanics, But In Which Only Relations Between Observable Quantities Occur.

[t]he Atoms Or Elementary Particles Themselves Are Not Real; They Form A World Of Potentialities Or Possibilities Rather Than One Of Things Or Facts.

Many People Will Tell You That An Expert Is Someone Who Knows A Great Deal About The Subject. To This I Would Object That One Can Never Know Much About Any Subject. I Would Much Prefer The Following Definition: An Expert Is Someone Who Knows Some Of The Worst Mistakes That Can Be Made In The Subject, And How To Avoid Them.

Modern Physics Has Changed Nothing In The Great Classical Disciplines Of, For Instance, Mechanics, Optics, And Heat. Only The Conception Of Hitherto Unexplored Regions, Formed Prematurely From A Knowledge Of Only Certain Parts Of The World, Has Undergone A Decisive Transformation. This Conception, However, Is Always Decisive For The Future Course Of Research.

The Existing Scientific Concepts Cover Always Only A Very Limited Part Of Reality, And The Other Part That Has Not Yet Been Understood Is Infinite.
