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.
The Australian Acoustic Observatory project, described by its creators as a kind of “Google Street View of sound,” is a new acoustic sensor network of hundreds of microphones and digital audio recorders distributed across multiple remote ecosystems on the continent. The solar-powered system will record animal and natural sounds continuously for 5 years. According to […]

Weighted blankets are officially a thing. And if you’ve ever tried one, you know there’s a reason for the fuss. Parents have known for generations that swaddling a baby has a profound calming effect, and the gentle pressure that blanket weights provide can have the same effect on restless sleepers. Pretty much all parts of […]

In the early days of the web, everyone wanted a .com domain for their site. As a result, all the good ones got snapped up. But .com no longer has the cachet it once did. In fact, many new businesses and individuals are opting for other top-level domain extensions. One of the most memorable is […]
