Richard Feynman — The Key to Science

“If it disagrees with experiment, it is wrong.”

In this video from the 60s Richard Feynman explains the key to science with his timeless wisdom. It is the capacity to be wrong that moves us forward.

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.
