In everything that relates to science, I am a whole Encyclopaedia behind the rest of the world.

Science is the systematic classification of experience.

There is no greater impediment to progress in the sciences than the desire to see it take place too quickly.

It is a good morning exercise for a research scientist to discard a pet hypothesis every day before breakfast. It keeps him young.
