Richard Feynman

“For a successful technology, reality must take precedence over public relations, for nature cannot be fooled.”

“Tell your son to stop trying to fill your head with science — for to fill your heart with love is enough!”

“I don't know anything, but I do know that everything is interesting if you go into it deeply enough.”

“You can recognize truth by its beauty and simplicity.”

“I can live with doubt, and uncertainty, and not knowing. I think it's much more interesting to live not knowing than to have answers which might be wrong.”

“I learned very early the difference between knowing the name of something and knowing something.”

“What I cannot create, I do not understand.”

“I think I can safely say that nobody understands quantum mechanics.”

“Nature uses only the longest threads to weave her patterns, so each small piece of her fabric reveals the organization of the entire tapestry.”

“The first principle is that you must not fool yourself — and you are the easiest person to fool.”

“Science is the belief in the ignorance of experts.”
