Our latest paper will hopefully be useful to people new to crystal plasticity and explains our code starting from the fundamental equations. Code, examples and paper are open access. OXFORD-UMAT: An efficient and versatile crystal plasticity framework doi.org/10.1016/j.ijso…

@thezachmeister @ZPEdisclosure Helion’s Polaris demos fusion pulses at insane temperatures. It’s a big step forward but there is still a long way to go before net energy generation.

@edtarleton @ZPEdisclosure Also, to respond to the second take, Helion has already shown it can be done but I don't know what's considered "compact" because the size of a truck doesn't seem compact. Compared to a massive facility it IS compact though.

Skunk Works has a decades-long pattern: Build something insane in secret → fly it for years before anyone knows → eventually declassify it when it's already obsolete and they've moved on to the next thing. U-2: flew 4 years before the public knew. SR-71: classified for years. F-117: flew for 7 years before they admitted it existed. Have Blue: still barely talked about. So when Charles Chase says "we have compact fusion" and then goes dark — that's not failure. That's the pattern working exactly as designed.

@Imperator047 @ZPEdisclosure I’m not saying a compact fusion reactor will never happen in the future. I’m saying it hasn’t happened yet. It’s not being suppressed or kept secret from the public; it’s just extremely difficult to achieve, and so far no one has managed it.

@edtarleton @ZPEdisclosure uh huh... yet TAE has solved fusion and is scaling for commercial use literally right now...

@thezachmeister @ZPEdisclosure Pressurised water reactors (PWRs) compact fission designs very different to fusion.

@edtarleton @ZPEdisclosure So what kind of reactors are on the nuclear submarines and aircraft carriers?

@Kekius_Sage To spend time with dogs.

Can all humans share one ultimate reason for living?

@ayushphy Also. Professor Roger Penrose is a genius!

Why did Roger Penrose, an Englishman, discover singularity theorems for black holes? Kip Thorne suggests it’s because British universities emphasized advanced math, particularly topology, far more than American universities: "The reason, I suspect, was the undergraduate training of British theoretical physicists. They typically major in mathematics as undergraduates, then do Ph.D. research in departments of applied mathematics or departments of applied mathematics and theoretical physics. In America, by contrast, aspiring theoretical physicists typically major in physics as undergraduates, and then do Ph.D. research in physics departments. Thus, young British theoretical physicists are well versed in esoteric branches of mathematics which have not yet seen much physics application, but they may have a weak background in “gutsy” physics topics such as the behaviors of molecules, atoms, and atomic nuclei. By contrast, young American theoretical physicists know little mathematics beyond what their physics professors have taught them, but are deeply versed in the lore of molecules, atoms, and nuclei. To a great extent, we Americans have dominated theoretical physics since World War II, and we have foisted on the world's physics community our scandalously low mathematical standards. Most of us use the mathematics of fifty years ago and are incapable of communicating with modern mathematicians. With our poor mathematical training, it was difficult for us Americans to absorb and start using the topological methods when Penrose introduced them."

@mathladyhazel Dalton’s model was more like ~1800 I think 🤔

Atom model evolution.

@WolfofX ❤️❤️

Growing old together is a good thing

🔥New preprint Thermomigration can dominate hydrogen transport in heat-carrying metals like iron/nickel heat exchangers and zirconium nuclear cladding. The first thermodynamically consistent framework for thermomigration and a simple graphical method. doi.org/10.48550/arXiv…

@TheProjectUnity What is it made of? Aluminium Alloy? Maybe titanium alloy if it’s newer. It looks like a modified spherical rocket fuel tank. What are people claiming it to be? Actually I don’t think I want to know 🙈

What are peoples thoughts on The Buga Sphere? An ancient and potentially technological relic from over 12,500 years ago or a clever hoax?

@oprydai In QM, these symmetries are generated by operators and their commutation relations place limits on what can be known Space translations => momentum operator [x, p] = iℏ => Δx Δp ≥ ℏ/2 Time translations => energy (Hamiltonian) => leads to the energy–time uncertainty relation

stop memorizing formulas look for what doesn’t change that’s the whole game Noether’s theorem: if a system has a symmetry it has something it cannot lose → time looks the same → energy stays constant → space looks the same → momentum stays constant → rotation looks the same → angular momentum stays constant not a coincidence not a trick a rule change the perspective if the system doesn’t care something is being preserved underneath this is why physics works not because of equations but because reality has structure find the symmetry you find the invariant everything else is surface noise

@JonahMessinger @ZPEdisclosure Interesting thank you. I’ll have a look at it, 234 pages - that’s a book not a paper!

@edtarleton @ZPEdisclosure So there’s more than meets the eye here even if the generic discourse about the topic in the zeitgeist leaves much to be desired. With regard to if it’s possible I’ll point you to our arxiv manuscript: arxiv.org/abs/2501.08338 We’ll submit an updated version to a journal this year

Why did Google spend $10 million investigating cold fusion in 2019 if it was conclusively debunked in 1989? Google employs some of the smartest scientists on Earth. They have access to every paper ever published. They know the history. They spent $10 million anyway. Either Google's scientists are stupid, or the "debunking" left enough questions unanswered to justify eight figures of research. Which seems more likely?

@PaulParkerG @AshtonForbes Scientists love being proven wrong, means we learned something new. Science runs on falsification. No physicist or engineer I know fears radical ideas. We just need solid evidence. So far there’s none for net useful ZPE extraction, and thermodynamics implies it’s impossible.

@AshtonForbes They are just terrified that if ZPE extraction turns out viable (Casimir ≠ zero, negative energy exists), their whole career defending thermodynamic purity looks like 17th-century geocentrism.

I'm a healthcare IT guy. So why are all these PhD physicists terrified to debate me about Zero Point Energy? It should be easy to prove me wrong. They dodge because they can't answer basic questions about the Universe. Academia has become the clergy, devoid of scientific thinking.

@Andercot Very few systems are massive enough to worry about gravity and small enough to need quantum theory at the same time. Physics works so incredibly well in almost every situation that any grand unified theory would have to reduce to our current theories at low energies.

Physicists: "The greatest issue of our time is that physics is fundamentally incomplete, that we have no firm footing from which to explain our best theories" Also Physicists: "That's completely impossible, the laws of physics forbid it."

@Yearyy_ Yes exactly, it’s really weird. I’ve never seen it this bad before. There are so many of them and they are all so convinced they are right and know better than actual experts.

@edtarleton They aren’t even capable of prompting the ai for harsh peer review! I mean come the fuck on. Dunning Krueger.

So many men on this app think they have developed a grand unified theory of physics. I must have seen >100 bios which claim they have discovered revolutionary new physics. BTW None of them have, it’s always either flawed or just total nonsense. This is why we have peer review!

@JoeECusick @Samuel_Gregson Photons are neutral. Charge is conserved because positron (+1) + electron (−1) = 0. Energy, momentum, everything checks out. No ‘spacetime conversion’ needed just standard QED. You can look it up in any undergrad textbook.

@edtarleton @Samuel_Gregson The .511 MeV photons energy exactly equals the mass of the particles. Only the mass. Says nothing about the charge.

Explained here! youtu.be/GaPEoyITTXc?si…

@drdwhitehouse 🎯

The fake videos mask a hard truth. If you lack the basic foundations of physics you cannot go beyond meaningless sci fi memes that explain everything and thus nothing. Science is a way of thinking so you don't get fooled. This is a way of fooling yourself.

@JoeECusick @Samuel_Gregson No electron positron annihilation produced a pair of 0.511 MeV photons. I did the experiment myself when at school! The rest of your post is just word salad.

@Samuel_Gregson In electron/positron annihilation, the charge converts to spacetime, indicating Quantum Gravity is two plus two dimensional spacetime t,x and y,z.
