   Re RAISE and ARISE: they are not pointers to the same place in wordspace in the same way that 1+2+3 and 2+3+1 are in sumspace. Re your second point: I love wordle. I'd love a game with similar game play that obeyed mathematical prin

   I finished about 20 seconds slower than I would have if the animation hadn't lagged as much.

   The cosmic microwave background makes even deep intergalactic space warmer (3 or 4 K) than the inside of Earth’s best fridges (the best as low as nanoK). 3 or 4 K is easy to achieve using liquid helium cooling, which is presumably why eg.

    I am a LQCD practitioner. “Very hard” means that even with a nontrivial fraction of all the available leadership-class supercomputing in the world we don’t have enough computer power.

    That’s just a back-of-the-envelope calculation. Nobody knows how to do a bone-fide calculation because we don’t have an accepted quantum theory of gravity.

    Resonances are like vibrations on a trampoline; stable particles are more like lumps in a carpet. Usually what keeps particles stable is that they carry some quantum number(s) that is/are conserved, and no lighter combination of partic

    Not for nothing but Shockley, Bardeen, and Brattain were physicists awarded a Nobel "for their researches on semiconductors and their discovery of the transistor effect". Bardeen also won a separate Nobel for a theory of superco

    If you're ever in Bonn, I very strongly recommend the Arithmeum, a museum full of devices built for computation: abaci, clocks, mechanical calculators, vacuum tube devices, modern machines. https://www.arithmeum.uni-bonn.de&

    I think you may be over-simplifying. We have relativistic quantum-mechanical theories, and we can formulate quantum field theories on curved background spacetimes.

    It seems this article went into the second-chance pool, which is great! It didn't get much discussion last time around but might spurn a lot of interesting threads. However, something I find a little upsetting: I commented the first

    I appreciate what you’re trying to get at, but it’s not right. Gravitational waves exist in GR even in theories with no matter / Higgs. The Higgs is a scalar field; gravitational waves are spin-2.

    I would push back on this. Irredeemably suspect? The Nobel committee doesn't make theory awards until they are supported by experiment. There was basically no new particle physics data for 30 years. Then they found the Higgs and th

    The Nobel Prize in Physics often goes to "tooling" experimental work. Think: blue LEDs, CCDs, fiber optics, optical tweezers, things like that. Not that anybody asks me, but I would advocate a similar tooling award split between

    We're not all the way there yet, but this is a hot and rapidly-advancing topic. See, eg. https://arxiv.org/abs/2111.06948 and sources therein.

    As a physicist I'd say these things are well understood. - Why do certain particles decay into other particles? Quantum mechanics is totalitarian: what ever is not forbidden is mandatory. Forbidden: excluded by some symmetry principle
