Every Tool Carries With It The Spirit

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.

Nature Allows Only Experimental Situations To Occur Which Can Be Described Within The Framework Of The Formalism Of Quantum Mechanics

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.

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.

An Expert Is Someone Who Knows Some Of The Worst Mistakes That Can Be Made In His Subject And How To Avoid Them.
