The more thoroughly I conduct scientific research, the more I believe that science excludes atheism.

Mathematics is the only good metaphysics.

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

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.

When you are face to face with a difficulty, you are up against a discovery.

If we can't express what we know in the form of numbers, we really don't know much about it.
