It Is A Primitive Form Of Thought

It Is One Thing For The Human Mind To Extract From The Phenomena Of Nature The Laws Which It Has Itself Put Into Them; It May Be A Far Harder Thing To Extract Laws Over Which It Has No Control. It Is Even Possible That Laws Which Have Not Their Origin In The Mind May Be Irrational, And We Can Never Succeed In Formulating Them.

Do Not Put Too Much Confidence In Experimental Results Until They Have Been Confirmed By Theory.

Schrödinger's Wave-mechanics Is Not A Physical Theory, But A Dodge - And A Very Good Dodge Too.

We Have Found That Where Science Has Progressed The Farthest, The Mind Has But Regained From Nature That Which The Mind Has Put Into Nature. We Have Found A Strange Foot-print On The Shores Of The Unknown. We Have Devised Profound Theories, One After Another, To Account For Its Origin. At Last, We Have Succeeded In Reconstructing The Creature That Made The Foot-print. And Lo! It Is Our Own.

Don't Believe The Results Of Experiments Until They're Confirmed By Theory.
