Just As Houses Are Made Of Stones,

Mathematicians Are Born, Not Made.

Science Is Built Up With Facts, As A House Is With Stones. But A Collection Of Facts Is No More A Science Than A Heap Of Stones Is A House.

If We Knew Exactly The Laws Of Nature And The Situation Of The Universe At The Initial Moment, We Could Predict Exactly The Situation Of The Same Universe At A Succeeding Moment.

...the Feeling Of Mathematical Beauty, Of The Harmony Of Numbers And Of Forms, Of Geometric Elegance. It Is A Genuinely Aesthetic Feeling, Which All Mathematicians Know

A Sane Mind Should Not Be Guilty Of A Logical Fallacy, Yet There Are Very Fine Minds Incapable Of Following Mathematical Demonstrations.
