Science is bound, by the everlasting vow of honour, to face fearlessly every problem which can be fairly presented to it.

Nothing can be more fatal to progress than a too confident reliance on mathematical symbols; for the student is only too apt to take the easier course, and consider the formula not the fact as the physical reality.

Overwhelmingly strong proofs of intelligent and benevolent design lie around us... the atheistic idea is so nonsensical that I cannot put it into words.

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.

The atheistic idea is so nonsensical that I do not see how I can put it in words.

There is nothing new to be discovered in physics now. All that remains is more and more precise measurement.

There is nothing in science which teaches the origin of anything at all.
