Do Not Imagine That Mathematics Is Hard

I Believe That The More Thoroughly Science Is Studied, The Further Does It Take Us From Anything Comparable To Atheism.

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.

You Know Only Insofar As You Can Measure.

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