I haven’t been JUST listening to YouTube lately, but I’ve got the algorithms delivering me some pretty good stuff. I listened to this one while pulling up carpet today. Krauss had a chance to deliver a bunch of great one liners.
He gets a few moments in the beginning to talk generally, and uses a bunch of great quotes.
After 20 minutes the questions switch to talking about indigenous knowledge in schools. It gets a little repetitive.
“Science can’t prove things to be absolutely true. It can prove things to be absolutely false.” Nothing is true on all scales at all times. Be willing to be proven false.
“When the predictions we make are verified, and the tools we build based on those predictions work, it tells us we caught something crucial about nature.”
“Many scientists may be the opposite of humble, but science itself is perhaps the most humble of activities, because it doesn’t presume the universe was created for us or cares about us.”
Defines science.
“There’s no end of science as far as we know.”
“The process is the only known way to get knowledge about the world.” He says as an aside that “known” is being polite. “Wisdom may come from reflection, but knowledge comes from observation and testing.”
“I make things up all the time, but then I test them to see if they have anything to do with reality. Most of the time they don’t. As humans we’re allowed to do that. What’s anti-scientific is the dogmatic insistence that what you make up is true in advance of, or after testing it.”
Feynman - “First we guess, then we test.”
“Every time a student understands something for the first time, for them it’s the first time in the history of the universe that it’s been understood. It’s a process of discovery that we should celebrate by asking questions, by being willing to say ‘I don’t know’.”
“When journalism puts up two sides on a scientific debate, often, one side is just wrong. That’s great, you don’t have to have a balance. It’s useful to talk about how people went down the wrong path, and found the wrong answer, but you don’t have to give equal time to nonsense.”
“The whole point about science is that it works. It’s quite clear that certain claims are wrong or not useful. We don’t vote on the ideas we like. Nature determines what ideas work. Our job is to try and uncover what ideas do work.”
“There’s a well kept secret, but scientists are human beings. Reason is the slave of fashion. Human beings have a lot of reasons for what they do, they can be fooled, can be dogmatic, but the process of science overcomes the natural tendency to want to believe. If it’s done right.”
