Michio Kaku was a theoretically physicist at one time. He basically admitted that at one point he realized you get a massive divide by zero error as you consider things like black holes, or the total amount of matter in the Universe.
Then he left. He’s making more money now too.
I like him, in that he subscribes to Feynman and Jacques Barzun’s position that a real scientist can make the universe available to regular people.
It had nothing to do with being egalitarian. If you understand the universe, really understand it, you should be able to explain it to a reasonably prudent person.
Feynman was on the blue ribbon panel examining the Challenger explosion. Lots of politics, and lots of arguing.
Feynman knew it came down to the gaskets. Said that they weren’t rated for the cold weather that was present at the launch.
They began to shout him down. He had obtained a gasket. Rather than say a word, he put the gasket into the pitcher of ice water that they gave the panelists. He waited a minute, then took the gasket out. Brittle, it basically came apart in his hand.
End of discussion. That’s a scientist - just go out and prove it. Design an experiment and prove your theory.
Einstein said, “If you can’t explain it simply, you don’t understand it well enough.”
