We Will Have To Abandon The Philosophy

The Incomplete Knowledge Of A System Must Be An Essential Part Of Every Formulation In Quantum Theory. Quantum Theoretical Laws Must Be Of A Statistical Kind. To Give An Example: We Know That The Radium Atom Emits Alpha-radiation. Quantum Theory Can Give Us An Indication Of The Probability That The Alpha-particle Will Leave The Nucleus In Unit Time, But It Cannot Predict At What Precise Point In Time The Emission Will Occur, For This Is Uncertain In Principle.

There Is A Fundamental Error In Separating The Parts From The Whole, The Mistake Of Atomizing What Should Not Be Atomized. Unity And Complementarity Constitute Reality.

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.

Can Quantum Mechanics Represent The Fact That An Electron Finds Itself Approximately In A Given Place And That It Moves Approximately With A Given Velocity, And Can We Make These Approximations So Close That They Do Not Cause Experimental Difficulties?

What We Observe Is Not Nature Itself But Nature Exposed To Our Method Of Questioning. Our Scientific Work In Physics Consists In Asking Questions About Nature In The Language That We Possess And Trying To Get An Answer From Experiment By The Means That Are At Our Disposal.
