  3. #Physicists think they've resolved the #proton size puzzle
    There has been considerable debate among physicists over the last 15 years about conflicting measurements of the charge radius of a hydrogen atom’s proton—some confirming the predictions of our strongest theoretical models, others suggesting it was smaller than expected. The evidence has tilted in favor of a smaller proton radius and against new #physics.

  13. 🤓 Ah, yes, because the world was just clamoring for yet another rehash of the Manhattan Project. We *totally* needed a reminder that dropping atomic bombs was a big news story—did you know #physicists were involved? 🚀 The real bombshell here is how a few paragraphs can feel longer than the entirety of #WWII. 📚💥

    The new work adds to some interesting questions about what #physicists deem relevant in their #studies of #time. ❜❜

  17. 2/2…many are generally confused by a certain cadre of #Physicists on the one hand describing tools from #StringTheory they know and love on while calling out it’s flaws on the other (that generally being the failure to cough up a viable #TheoryOfEverything) while failing to mention that these are problems with which the entirety of #Physics has also failed at spectacularly. Watch and you’ll know when folks r using string theory tools as explainers while dissing string theory.

  19. Hey #physicists. Could there be a kind of quark matter (maybe with top quarks) that was so dense a lump of it could fit inside its own Schwartzschild radius?

    If so, from outside the event horizon, how would that even in principle be distinguishable from a black hole with a singularity inside?

  20. How Plausible Is ‘#ProjectHailMary’? #Astrophysicists Have Thoughts
    Based on hard #sciencefiction, a genre that prioritizes scientific accuracy, the blockbuster gets a lot right but misses a few things, experts say.
    Armchair #physicists and even some actual physicists have powered countless online threads with questions around interstellar travel, alien life and why Grace, who has a doctorate in microbiology, can’t seem to balance a centrifuge.

  21. #physicists #engineers, #electricians and #roofers

    I've got a wooden house. A new roof has gone on. After the removing of solar hotwater pipes, there is no longer any path to ground from the corrugated steel roof.
    (How do I know? One of the screws cut into a cable and electrified the whole thing. No RCD tripped. Golly.)

    Would you strap it to earth? To a sacrificial anode? Neither? What reasoning please? We live on top of a hill and have lovely thunderstorms.

  22. #Physicists dream up ‘spacetime #quasicrystals’ that could underpin universe
    Orderly structures that never repeat can exist in melded space and time of Einstein’s relativity
    Instead of existing in two or three spatial dimensions, these quasicrystals’ structures would bridge space and time. Although theoretical, the researchers suggest that such spacetime quasicrystals may appear in nature, perhaps even underlying the structure of the universe.

  23. 1/n Notes on #UAP Discussions : This particular exploration is a milestone. If we map what they eventually wind up talking about to vexing questions in current #Physics we have a direct confrontation with #GeneralRelativity, #QuantumMechanics, and the applied mass- energy firewall problem that lies at at the heart of several open problems in #Cosmology and the SM. It should be noted that the intuition of #Engineers in this case is capable of beating #Physicists to the punch.
    There is a bit…

  24. #Fusion #Physicists Found a Way Around a Long-Standing Density Limit
    For a long time, the #GreenwaldLimit was accepted as a given and incorporated into fusion reactor engineering. The new work shows that precise control over how the #plasma is created and interacts with the reactor walls can push it beyond this limit into what physicists call a 'density-free' regime.

  25. “While the Avcoat material is very similar to the one used in the Apollo missions, it has been reformulated slightly for #Artemis. This is partially due to having to re-engineer the technology, and partially to meet environmental legislation outlawing certain compounds. The other change is the way the Avcoat has been applied. In the #Apollo missions, one large piece of #Avcoat was used throughout the bottom of the spacecraft, but in the Artemis I and II missions, the heat shield is made up of more than 186 blocks or tiles.

    It's got a major inherent problem … a structural problem, and they do not understand the #physics of that problem," — Dr Charlie Camarda, Astronaut (STS-114), NASA Thermal Structure Laboratory.

    1960s Apollo era #Engineers & #Physicists are still peak rocket engineering.

  26. #Physicists discovered# neutrinos 70 years ago. The ghostly #particles still have secrets to tell
    Exist they do. Not in scarcity, either. They are most abundant massive #particle in universe, outnumbering protons about a billion to one. Scientists are still grappling with what these particles are about. And neutrinos are not just one type of particle, either, but trio of particles — electron neutrinos, muon neutrinos, and tau neutrinos — and corresponding antimatter.

  27. Eldest of 3 daughters of Delaware shipbuilder/state senator Wilson Cannon & Mary Jump, Annie’s mom taught her the constellations & encouraged her to pursue her own interests. She studied physics with Sarah Frances Whiting, 1 of few US women #physicists at the time, at Wellesley & became valedictorian in 1884. She returned home, worked various jobs, & published her photos over next decade. She lost most of her hearing possibly due to scarlet fever. 🧵2/

  28. 🌰🔬 A team of scientists just threw a bunch of random junk (peanuts and leaves?!🍂) into a blender and somehow got lasers out of it. 🚀⚡ Meanwhile, actual #physicists everywhere are questioning their life choices. 🤦‍♂️

  31. In a promising breakthrough, MIT #physicists have today reported their observation of new key evidence of unconventional superconductivity in “magic-angle” twisted tri-layer #graphene (MATTG) — a material that is made by stacking three atomically-thin sheets of graphene at a specific angle, or twist, that then allows exotic properties to emerge.
