If We Can't Express What We Know

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

To Measure Is To Know.

I Often Say That When You Can Measure What You Are Speaking About, And Express It In Numbers, You Know Something About It; But When You Cannot Measure It, When You Cannot Express It In Numbers, Your Knowledge Is Of A Meagre And Unsatisfactory Kind.

If You Can Not Measure It, You Can Not Improve It.

Ether Is The Only Substance We Are Confident Of In Dynamics. One Thing We Are Sure Of And That Is The Reality And Substantiality Of The Luminferous Ether.
