“Heavier-than-air flying machines are impossible.”

“In science there is only physics; all the rest is stamp collecting.”

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

“The true measure of a man is what he would do if he knew he would never be caught.”

“The atheistic idea is so nonsensical that I cannot put it into words.”

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

“Large increases in cost with questionable increases in performance can be tolerated only in race horses and women.”
