Experiment Is The Sole Source

The Scientist Does Not Study Nature Because It Is Useful To Do So. He Studies It Because He Takes Pleasure In It, And He Takes Pleasure In It Because It Is Beautiful. If Nature Were Not Beautiful It Would Not Be Worth Knowing, And Life Would Not Be Worth Living. I Am Not Speaking, Of Course, Of The Beauty Which Strikes The Senses, Of The Beauty Of Qualities And Appearances. I Am Far From Despising This, But It Has Nothing To Do With Science. What I Mean Is That More Intimate Beauty Which Comes From The Harmonious Order Of Its Parts, And Which A Pure Intelligence Can Grasp.

A Scientist Worthy Of His Name, About All A Mathematician, Experiences In His Work The Same Impression As An Artist; His Pleasure Is As Great And Of The Same Nature.

But All Of My Efforts Served Only To Make Me Better Acquainted With The Difficulty, Which In Itself Was Something.

Mathematical Discoveries, Small Or Great Are Never Born Of Spontaneous Generation They Always Presuppose A Soil Seeded With Preliminary Knowledge And Well Prepared By Labour, Both Conscious And Subconscious.

Intuition Is More Important To Discovery Than Logic.
