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.

...separation Of The Observer From The Phenomenon To Be Observed Is No Longer Possible.

The Very Act Of Observing Disturbs The System.

The Violent Reaction On The Recent Development Of Modern Physics Can Only Be Understood When One Realises That Here The Foundations Of Physics Have Started Moving; And That This Motion Has Caused The Feeling That The Ground Would Be Cut From Science
