Feynman, the scientific method and evolution.

I'm sure I've mentioned it before but science is an evolutionary algorithm. And I love how well Feynman's explanation of science fits into the algorithm itself.

Guess -> Compute consequences of guess -> Agrees with reality?

If it fails to agree with experiment, the guess is absolutely wrong, even if it's beautiful. That's very closely akin to the typical algorithm employed by biology:

Mutation -> Develop organism out of DNA -> Dies?

If it fails to thrive, the mutation was less fit. The fact is that without the unforgiving nature of science or the unforgiving nature of nature, things don't work at all.
