eleven things tagged “physics”
I was lucky. I went to good schools, I had excellent teachers. I was in the right place at the right time. Paul Dirac Opportunity and luck bestow their benisons upon a once-in-a-generation genius, mathematical mystic, and one of the greatest theoretical physicists to have walked the planet. You…
On Consciousness
It is remarkable that mind enters into our awareness of nature on two separate levels. At the highest level, the level of human consciousness, our minds are somehow directly aware of the complicated flow of electrical and chemical patterns in our brains. At the lowest level, the level of single at…
The Most Perfectly Timed Shot in the History of Television
Fat claim, but I cannot imagine anything more badass than this. /misc/p/perfect-timing.mp4 Here’s the full video. The presenter’s James Burke. From the YouTube comments: I remember seeing an interview with him and the person asking him the question asked him “How was that shot perfectly timed?” He…

Here’s the full graphic. Watch anything by PBS SpaceTime on the subject 💯…
Developer site. A beautiful meditation that’s just the right length. Reminded me of “Osmos”, an all-time favorite. Won an Apple Design Award on 2018 (with “Florence”.)…
Concave Mirror, Ball, Black Hole
This video of a ball swinging in front of concave mirror (starts at 2:00, cannot embed for some reason) reminded me of simulations of what it would be like if one fell into a Black Hole. Here’s a Schwarzschild Black Hole, one “with mass, but with no electric charge, and no spin.” (Source) https://vi…
Timelapse of the Future
Best thing I’ve seen this year. About as spiritual as it gets. https://www.youtube.com/watch?v=uD4izuDMUQA After an unimaginable length of time, even the black holes will have evaporated and the universe will be nothing but a sea of photons, gradually tending towards the same temperature, as the ex…
Muons
Minute Physics on how Muons reaching terrestrial detectors from the upper atmosphere are direct proof of time dilation/length contraction in Special Relativity. https://www.youtube.com/watch?v=rVzDP8SMhPo What a Boss 🙏 💯…
Freeman Dyson on Richard Feynman
When we arrived we were introduced to Henry Bethe, who is now five years old, but he was not at all impressed. The only thing he would say was “I want Dick. You told me Dick was coming,” and finally he had to be sent off to bed, since Dick (alias Feynman) did not materialise. About half an hour lat…
