The talk itself is great and covers some important stuff. (Of course, it's Feynman!) The key thing here is the connection between theoretical understandings of how the universe works and practical observations. Theories are used to make predictions. When the predictions turn out to be correct, we get some more evidence that the theory is on the right track. Here, Feynman talks about how the theory of gravity led to the discovery of the speed of light, and how knowledge of the effect of gravity on planetary orbits led to the discovery of the planet Neptune. Very cool stuff.
But what stood out to me—and what makes this different from all the old!Feynman videos I've seen—is the persona his younger self projects. Born and raised in Queens, the young Feynman comes across, at least in accent and physical mannerisms, like some big mafia palooka straight out of central casting. Most likely, my startled reaction to this is due to Midwestern bias and being raised in an era where American regional differences in accent and culture have been largely flattened out. But it's still fascinating ... and amusing as hell to hear a guy who looks and sounds like he should be guarding hostages or threatening shop owners instead talking about gravitational theory.
Tomorrow the final hammer goes down on an archive of original Nikola Tesla patents, lightbulb design drawings by Thomas Edison, a World War II Enigma Machine, Stephen Hawking’s personal Simpsons figure, and many other science-related curiosities in Christie’s “Eureka!” auction.
Every year, hundreds of thousands of horseshoe crabs, a threatened species, are “milked” for up to 30% of their blood that’s used to test new medical drugs, including possible COVID-19 vaccines, for bacterial contamination. The animals are eventually released but, surprise, a large percentage of them die. Revive & Restore, the wildlife conservation organization most […]
Exploding Head Syndrome (EHS) is an actual medical condition in which an individual sometimes experiences an explosive sound inside their head when drifting off to sleep or just waking up. The big boom may also be accompanied by a flash of light. Also called “episodic cranial sensory shock,” cases have been reported in the medical […]
Unlike the unquestioned effectiveness of a solid strip of duct tape, you never quite know what you’re going to get when you try to repair something with glue, do you? Whether it’s the material itself that you’re gluing or how much glue you apply or how long you let it sit before testing, there’s always […]
Now that we’re past July 4th, we’re truly turning smack into the sharpened teeth of the summer heatwave season. As temperatures and humidity spike, it just makes all the rest of the nation’s current problems that just tiniest bit more irritating, doesn’t it? Hey, we’re all in this together. So if we can help chill […]
While we obviously don’t ever want to lose sight of exactly why we’re all wearing face coverings now in the first place, it’s also impossible to ignore that masks have already started to evolve in the public consciousness. The mask started as simply a means of combating infection. Then, it became an avenue of free […]
