Zitate von Richard Feynman

John & Mary Gribbin, Richard Feynman, A life in science, S. 178

In general we look for a new law by the following process.

First we guess it.

Then we compute the consequence 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 of 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.

„...Finally, there is a most remarkable coincidence: The equations for many different physical situations have exactly the same appearance. Of course, the symbols may be different – one letter ist substituted for another – but the mathematical form oft he equations is the same. This means that having studied one subject, we immediatly have a great deal of direct and precise knowledge about the solutions of the equations of another...“
