Richard Feynman on the uncertainty of knowledge - video

[mklotz]

One of the first things I learned in college, though not in any classroom, was that most of what is wrong in the world stems from man's need to have an explanation for everything, even if that means conjuring up magical beings with unrealistic capabilities.

Real science doesn't need immediate explanations; packaging observations into an after the fact theory is good enough so long as one is willing to discard that theory as soon as a contradiction is observed and proved genuine.
