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.
When people hear voices others can’t, the prevailing scientific model describes this as psychosis due to brain abnormality, chemical imbalance, or other affliction. But scientists have now reliably induced auditory hallucinations in some people not diagnosed with psychosis.
Tiny micromotors about the width of a human hair traveled through a mouse’s stomach delivering antibiotics to treat a stomach ulcer. The motors are powered by bubbles. According to the researchers from the University of California San Diego, the microrobot-based treatment proved more effective than regular doses of the medicine. From New Scientist: The tiny […]
In 1971, astronomer Frank Drake, the father of the search for extraterrestrial intelligence, drew a map pinpointing Earth in our galaxy. That diagram, a “pulsar map,” was etched on a plaque designed by Frank and Carl Sagan and first carried into space in 1972 by the Pioneer 10 and 11 spacecraft. In 1977, the pulsar […]
