If You Cannot Measure It, Then It

[referring To Fourier's Mathematical Theory Of The Conduction Of Heat] ... Fourier's Great Mathematical Poem.

Although Mechanical Energy Is Indestructible, There Is A Universal Tendency To Its Dissipation, Which Produces Throughout The System A Gradual Augmentation And Diffusion Of Heat, Cessation Of Motion And Exhaustion Of The Potential Energy Of The Material Universe

Mathematics Is The Only True Metaphysics.

When You Can Measure What You Are Speaking About, And Express It In Numbers, You Know Something About It.

Suppose That You Could Mark The Molecules In A Glass Of Water; Then Pour The Contents Of The Glass Into The Ocean And Stir The Latter Throughly So As To Distribute The Marked Molecules Uniformly Throughout The Seven Seas; If Then You Took A Glass Of Water Anywhere Out Of The Ocean, You Would Find In It About A Hundred Of Your Marked Molecules.
