To Measure Is To Know.

If You Study Science Deep Enough And Long Enough, It Will Force You To Believe In God.

When You Are Face To Face With A Difficulty, You Are Up Against A Discovery.

All Of Science Can Be Divided Into Physics And Stamp-collecting.

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.

To Measure Is To Know.
