[of The Ether] It Is No Greater

Accurate And Minute Measurement Seems To The Non-scientific Imagination, A Less Lofty And Dignified Work Than Looking For Something New. But Nearly All The Grandest Discoveries Of Science Have Been But The Rewards Of Accurate Measurement And Patient Long-continued Labour In The Minute Sifting Of Numerical Results.

Questions Of Personal Priority, However Interesting They May Be To The Persons Concerned, Sink Into Insignificance In The Prospect Of Any Gain Of Deeper Insight Into The Secrets Of Nature.

Simplification Of Modes Of Proof Is Not Merely An Indication Of Advance In Our Knowledge Of A Subject, But Is Also The Surest Guarantee Of Readiness For Farther Progress.

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 Cannot Measure It, Then It Is Not Science.
