How so?
-
Energy doesn't have energy levels. Composite systems with attractive interactions do. How big would these shifts be in a Casimir-type experiment?
-
Sounds more like revenge/vendetta, and mutual assured destruction. Tit-for-tat in game theory.

If you jump in and recreate the experiment, like a few dozen labs did, you either confirm or refute the experiment, and your reputation isn't really on the line. I don't think anyone remembers any names other than Pons and Fleischmann. Similar with theory. There were people who leapt in with theoretical explanations of superluminal neutrinos (which may be a good example to contrast with cold fusion). Did they suffer any harm to their reputation? Probably not, because they didn't go public with their results, they went through the proper channels. I think perhaps being wrong isn't punished much as long as you do that. Or, conspiracy theorists even try and exploit physics. I don't think it's physics, per se, that owns the conspiracy; it's a rejection of mainstream physics that's involved. Perpetual motion has been around for a long time. Physics wants no part of it. As with my comment above, I think it didn't spawn this as much as gave it a new outlet to express itself. Like some other perpetual motion gambits, it's something an isolated crackpot can work on without being outrageously expensive.

They have a 4.2 sigma confidence interval, with more data to analyze, and this is a re-do of a previous experiment.

I think military pilots, and thus many astronauts, tend to be shorter than average. (anecdotally, the pilots and astronauts I’ve met tended to be on the shorter side) Fitting into the cockpit/capsule, and I suspect being shorter might hep you deal with high-g maneuvers.

Who coined the phrase "freedom of speech"?
swansont replied to ScienceNostalgia101's topic in Politics
So many people used “literally” when they should have used “figuratively” (e.g. “I literally died!” while remaining alive) that the definition has changed to incorporate that. So while your examples are extreme, and likely meant to be ridiculous, that’s actually how it works. (I could tell you I was having a gay experience until I tripped over a faggot, with the caveat that you should look up the old definitions and not use the modern lexicon) -

No, that’s not legitimate, or realistic. The reality is that the meaning of words change over time, and the person who coins a phrase may not be the one who popularizes it, possibly in another context. -

Certainly rehabilitation is not on the table if you’re dead.
-
But that’s not the sole goal of the justice system. Protecting society, rehabilitation and impacts on the aggrieved (i.e. “closure”) are factors, too.

! Moderator Note Complaining about reputation points is off-topic, as is vague and unsubstantiated criticism of the research process and the “defective vaccination system” (which also runs afoul of the rule on arguing in good faith)

Take it up with them; I don’t disagree. I was answering the question of why the explanations aren’t making the distinction between matter and antimatter. (i.e. “Why are they keep saying "muons decay to electrons"?”)
-
Because the distinction doesn't matter here. They're talking about muons and electrons as generations of leptons. Sorting out whether it's the matter or antimatter particle is a triviality.
-
I’ve only seen a reference to the Brookhaven result, and it’s not just the same design, it was the same storage ring, shipped to Fermilab and reassembled. CERN did a different experiment with muons which also hints at new physics. https://home.cern/news/news/physics/intriguing-new-result-lhcb-experiment-cern It could be rotation. The discrepancy is the decay energy with opposite orientation of the magnetic moment. Here’s a simplified explanation https://physics.aps.org/articles/v14/47
-
The naming isn’t the issue. This is just moving the problem around, but not solving it. You’d need a model that predicts this imbalance, whichever way you label it.
-
the matter/antimatter asymmetry is the issue of why we have matter and not antimatter around. The amounts are not equal, or symmetric g-2 refers to the muon magnetic moment experiment, in the nature link I added to my previous post I come from atomic physics, which gave us "optical molasses" and "Bose-nova" (both, I think, from the Wieman and/or Cornell research groups) so don't look to me for help.
-
So they say scientists don't know what the force is, exactly, but imply it will explain dark matter, these muon issues, matter/antimatter asymmetry, etc. Also, they imply this is a revelation, when we know the standard model is incomplete. I saw on twitter where it was stated the g-2 results from today used the same storage ring design as the previous results (which showed a similar disagreement with the standard model), meaning you can't rule out some systematic errors. edit: the calculations that incorporate better QCD values narrows the discrepancy between theory and experiment https://www.nature.com/articles/d41586-021-00898-z

Scandinavia isn’t a country https://checkinprice.com/average-and-minimum-salary-in-stockholm-sweden/ Sweden does not have an official minimum salary. Minimum salaries are generally negotiated through workers’ unions. As a reference, the salary for a McDondald’s cashier is hovering around 101 to 125 Swedish Krona, or roughly 15 USD per hour.

A question about radiation from a microvawe oven
swansont replied to Titus's topic in Classical Physics
And it gives off even less energy in microwaves, because those are inside the chamber. (unless it’s broken) A 1 kW microwave that’s 66% efficient at converting electrical energy to microwave energy is dumping 1 kW into the food and 500 W is waste heat, some/most of which is sent off to the outside environment. -
A question about radiation from a microvawe oven
swansont replied to Titus's topic in Classical Physics
I would think heat is much more likely than microwave leakage. I’m not sure how you eliminated that from consideration. There’s a lot more thermal energy involved as compared to microwave, outside of the chamber. -

swansont replied to fredreload's topic in Speculations
Than you aren’t hearing ultrasound, as you had claimed. Yes, you did say this. “I want nanometer resolution of the tissue, if I can see DNA, sure.” Right there in the OP The hubris of claiming you did not say things when there’s a written record in plain sight is astounding Tera, not tetra And there is scientific application here, if you had any interest in learning the science. That’s not defamation. That’s feedback for lazy thinking.
