There Are Things That Are

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.

The Problems Of Language Here Are Really Serious. We Wish To Speak In Some Way About The Structure Of The Atoms. But We Cannot Speak About Atoms In Ordinary Language.

Therefore, The Two Processes, That Of Science And That Of Art, Are Not Very Different. Both Science And Art Form In The Course Of The Centuries A Human Language By Which We Can Speak About The More Remote Parts Of Reality, And The Coherent Sets Of Concepts As Well As The Different Styles Of Art Are Different Words Or Groups Of Words In This Language.

The Reality We Can Put Into Words Is Never Reality Itself.

The Physicist May Be Satisfied When He Has The Mathematical Scheme And Knows How To Use For The Interpretation Of The Experiments. But He Has To Speak About His Results Also To Non-physicists Who Will Not Be Satisfied Unless Some Explanation Is Given In Plain Language. Even For The Physicist The Description In Plain Language Will Be The Criterion Of The Degree Of Understanding That Has Been Reached.
