“It doesn't make a difference how beautiful your guess is. It doesn't make a difference how smart you are, who made the guess, or what his name is. If it disagrees with experiment, it's wrong.”

“In general, we look for a new law by the following process: First we guess it; then we compute the consequences of the guess to see what would be implied if this law that we guessed is right; then we compare the result of the computation to nature, with experiment or experience, compare it directly with observation, to see if it works. If it disagrees with experiment, it is wrong. In that simple statement is the key to science. It does not make any difference how beautiful your guess is, it does not make any difference how smart you are, who made the guess, or what his name is — if it disagrees with experiment, it is wrong.”

“It doesn't matter how beautiful your theory is, it doesn't matter how smart you are. If it doesn't agree with experiment, it's wrong.”

“It's your gift, to see the beauty and the horror in ordinary things. It doesn't make you crazy, just different.”

“Don't dare to be different, dare to be yourself - if that doesn't make you different then something is wrong.”

“Clary, you're an artist, like your mother. That means you see the world in ways that other people don't. It's your gift, to see the beauty and the horror in ordinary things. It doesn't make you crazy — just different. There's nothing wrong with being different.”
