- (1/2) While most physicists don't put stock into numerology, I bet most have one which tickles their brain. For me, it is the Koide formula which relates the lepton masses to a fraction. The ratio Q is 0.666661(7) with the exact fraction 2/3 within the error bars. #Science #Physics 🧪⚛️🧵
- What Is Entropy? A Measure of Just How Little We Really Know.Exactly 200 years ago, a French engineer introduced an idea that would quantify the universe’s inexorable slide into decay. But entropy, as it’s currently understood, is less a fact about the world than a reflection of our growing ignorance. Embracing that truth is leading to a rethink of everything from rational decision-making to the limits of machines.By Zack Savistkyhttps://www.quantamagazine.org/what-is-entropy-a-measure-of-just-how-little-we-really-know-20241213/#books #science #physics #entropy
- Kurt Gödel found a solution to Einstein's equations that depicted a rotating universe, where all the space-time rotates. This universe would have closed timeline curves, that is, time travel would be possible.Gödel presented this result in a conference. John Wheeler was there and wrote that in such a universe you could live your life over and over again. In his book on Gödel, Palle Yourgrau says that Wheeler misunderstood Gödel (!).What Gödel was trying to show was that if time travel is possible, then time, as a subjective experience, can't exist, it's just an illusion. It's not that you repeat […]
- Fermions (half-odd-integer-spin particles) are weird about each other in a standoffish way. Bosons (integer-spin particles) are weird about each other in a 'stand uncomfortably close while talking' kind of way. https://xkcd.com/3027/#physics
- Remember that time when Elon Musk posted his homework from the one #physics class he attended before dropping out, as somehow being really impressive #math?The #billionaires faked being nerds just long enough for us to think they’re like us.It’s not that they wanted to be nerds. They don’t actually like physics. If they did, they’d stayed in college.They are narcissist dominators who can just naturally smell how to scam the most and get most power. #nerds were it.https://youtube.com/watch?v=GmJI6qIqURA
