Richard Feynman used to go up to people all the time and he'd say "You won't believe what happened to me today... you won't believe what happened to me" and people would say "What?" and he'd say "Absolutely nothing". Because we humans believe that everything that happens to us is special and significant. And that, and Carl Sagan wrote beautifully about that in The Demon-Haunted World - that is much of the source of religion. Everything that happens is unusual and I expect that the likelihood that Richard and I ever would've met. If you think about all the variables: the probability that we were in the same place at the same time, ate breakfast the same. Whatever. It's zero. Every event that happens has small probability... but it happens and then when it happens; if it's weird, if you dream one million nights and it's nonsense but one night you dream that your friend is gonna break his leg and the next day he breaks his arm - *sound of revelation*. So, the thing that physics tell us about the universe is that it's big, rare event happens all the time - including life - and that doesn't mean it's special.

There is a maxim about the universe which I always tell my students: That which is not explicitly forbidden is guaranteed to occur.

Every atom in your body came from a star that exploded. And, the atoms in your left hand probably came from a different star than your right hand. It really is the most poetic thing I know about physics: You are all stardust. You couldn’t be here if stars hadn’t exploded, because the elements - the carbon, nitrogen, oxygen, iron, all the things that matter for evolution and for life - weren’t created at the beginning of time. They were created in the nuclear furnaces of stars, and the only way for them to get into your body is if those stars were kind enough to explode. So, forget Jesus. The stars died so that you could be here today.

My area of research is something that in all fairness has no practical usability whatsoever and the thing is I'm often asked to apologize for that. It is interesting to me that people ask 'what's the point of doing that if it's not useful?' But they never ask that, or do they very rarely ask that about art or literature or music. Those things are not gonna produce a better toaster.

Now, since the time of Newton there had been a debate about whether light was a wave - that is, a traveling disturbance in some background medium - or a particle, which travels regardless of the presence of a background medium. The observation of Maxwell that electromagnetic waves must exist and that their speed was identical to that of light ended the debate: light was an electromagnetic wave.

The purpose of education is not to validate ignorance but to overcome it.

Education, Science, Skeptic

Share

And if you think about it, teaching kids - or allowing the notion that the earth is 6,000 years old to be promulgated in schools is like teaching kids that the distance across the United States is 17 feet. That’s how big an error it is. Now you might say, look, a lot of people believe that, so don’t we owe it to them to allow their views to be present in school? Well, as I’ve often said, the purpose of education is not to validate ignorance but to overcome it.
