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.
Texas State University’s Body Farm (AKA Forensic Anthropology Center at Texas State University or FACTS) is a 45-year-old facility where the corpses of medical body donors are left to decompose so that researchers can observe the rate at which human remains are consumed by the elements, scavengers and microbes, allowing them to accurately date the […]
A better understanding how a sperm swims its way toward an egg could help inform new treatments for male infertility. Researchers from the University of York have now come up with a mathematical formula to model how large numbers of moving sperm interact with fluid they’re swimming through. From the University: By analysing the head […]
Dr Gale Ridge is a public entomologist at the Connecticut Agricultural Experiment Station, where an average of 23 people a day call, write or visit; an increasing proportion of them aren’t inquiring about actual insects, they’re suffering from delusional parasitosis, and they’re desperate and even suicidal.
When you can’t wait for the world’s longest meeting to end, the mindless leg bouncing makes your boredom obvious and just annoys everybody else. Everyone knows the TPS reports need the damn cover sheet, but some sadistic colleague keeps forgetting, probably on purpose just to eat into your lunch hour. Enough is enough!While serving a […]
What could be more fun than a slingshot that shoots tiny airplanes? A slingshot that shoots tiny glowing airplanes of course! These toy planes are outfitted with ultra-bright LEDs, so you can fly all night without losing them in the trees.Whether you are a regular-sized child, or an overgrown adult one, these light-up flyers offer […]
You know the drill. You go to the dentist and they ask you how often you floss. You lie through your teeth and say, “every day!” (Bonus points if you have some cilantro or chives stuck in your gums from lunch). You don’t want to keep up the charade any longer, but rubbing that tiny strand […]
