What Is That We Human Beings Ultimately

Physics Is The Belief That A Simple And Consistent Description Of Nature Is Possible.

One Thought Spectra Are Marvellous, But It Is Not Possible To Make Progress There. Just As If You Have The Wing Of A Butterfly Then Certainly It Is Very Regular With The Colors And So On, But Nobody Thought One Could Get The Basis Of Biology From The Coloring Of The Wing Of A Butterfly.

When Asked ... [about] An Underlying Quantum World, Bohr Would Answer, 'there Is No Quantum World. There Is Only An Abstract Quantum Physical Description. It Is Wrong To Think That The Task Of Physics Is To Find Out How Nature Is. Physics Concerns What We Can Say About Nature.'

Our Task Is Not To Penetrate The Essence Of Things, The Meaning Of Which We Do Not Know Anyway, But Rather To Develop Concepts Which Allow Us To Talk In A Productive Way About Phenomena In Nature

The Present State Of Atomic Theory Is Characterized By The Fact That We Not Only Believe The Existence Of Atoms To Be Proved Beyond A Doubt, But Also We Even Believe That We Have An Intimate Knowledge Of The Constituents Of The Individual Atoms.
