Surely you understand what a prototype is, meaning the “Ruskies” aren’t using this technology yet. They’re trying to develop it, and there are no guarantees of success.

Which is not what we were talking about, but Russia’s overall inflation rate far exceeds the US’s over the last several years. https://tradingeconomics.com/russia/inflation-cpi Is the reason that you won’t address my point that you can’t back it up with facts?

Prove it. Given how you make stuff up, I will not assume that any assertion of yours is true without proof. The FED “collects” inflation? Do explain, please. US inflation is a problem for US exports, but we import far mor than we export, and there’s not a lot of exports I can think of that couldn’t be replaced from other sources. And the US is doing pretty well, inflation-wise https://gfmag.com/data/economic-data/worlds-highest-lowest-inflation-rates/ https://data.worldbank.org/indicator/FP.CPI.TOTL.ZG?locations=OE&most_recent_value_desc=false

Lots of it start-up costs, I imagine. Paying for the R&D paths that didn’t pan out, and a whole lot of testing. It’s hard, in part, because it’s dangerous. Mitigating risk can be difficult and expensive. And has nothing to do with DEI. Nothing to do with DEI.

It’s hard to tell if this is a serious question. Partly because of your “jokes” and partly because you don’t seem to have done a lick of research on the question. Incessant whining, based on ignorance, is hard to take seriously. The Apollo missions cost more than $300 billion in today’s dollars. (2023) https://taxfoundation.org/blog/apollo-moon-space-race-industrial-policy-cost/ (original cost was ~$25 billion) This shows that each mission cost less than $500 million, so even if you shave off the last 6 missions, that’s less than 1/8 of the overall cost (3 billion out of 25) https://www.statista.com/statistics/1028322/total-cost-apollo-missions/ So the new program is a lot cheaper, because certain things don’t have to be re-discovered, even as the hardware is remade with modern technology. But it’s not simple and it’s not easy.

And now we have the crypto reserve, so the government can contribute to the ponzi scheme while others cash out.

Not that distance, but the spacing between the ships (much like the circumference of the rotating disk does not require a solid rim; it would be the same with just spokes). But this ignores the fact that the distance doesn’t change, and as one ship lands another is launched, and the new ship is not moving at v. So there are always N ships in the distance L. Neither N nor L changes. N because it’s invariant, and L because the path itself is not moving, and that’s what matters. Since there is motion, there’s no issue with applying it. As the citations in my link address, it gives the explanation for the repulsion/attraction of parallel wires. Or you can apply relativity to come up with magnetism. Different explanations for the result.

! Moderator Note First rule in speculations is that it must be backed up by evidence or some sort of proof. It can’t be untestable, and you must provide evidence or a prediction that is testable. That typically requires a model of some sort. Your next post on the topic must comply with this.

Not to defend the Bible as being literally true, but this is an argument from silence, i.e. a fallacy. (related: absence of evidence is not evidence of absence) Does the Bible say how much food and water/wine Noah loaded on board? Or how many times they urinated/defecated? Do we assume the answer is zero because it’s not mentioned?

a) does it? (is this another joke?) b) the cost has nothing to do with DEI

So, the answer would be a “no, I won’t” (to “Can you put some effort into your “analysis”?”) “global elites are controlling the educational system” is just cheap, lazy, conspiracy theory Again, no analysis, no data. Just assertion. Inflation can be measured and compared with other countries that did not do quantitative easing. Why is it that they had even worse inflation? So-called cryptocurrencies are a scam, so it’s no wonder Trump supports them (he launched his own to cash in) and pardoned am associated scam artist, but surprising given his stance on drug dealers.

The wire is not length-contracted, because it is not moving. The electrons enter and leave at the end of the wire. So the number of electrons in that section is the same, regardless of this length contraction. This might be related to the rotating disk paradox; the radius is not changed but the circumference is not 2*pi*r. The solution is because there’s an acceleration involved (when the electrons turn the corner, in our case) which means you can’t naively apply Euclidean geometry to the description. https://simple.m.wikipedia.org/wiki/Rigidly_rotating_disk_paradox

Just to note, Th-90 is the wrong notation. The number in that format should be the atomic mass number, e.g. Th-233, U-235, O-16

They’re both men. See? Exactly the same. Can you put some effort into your “analysis”? This is pathetic. And arguably in bad faith (i.e. trolling) In any event, “Trump and Biden are two sides of the same coin, that the middle class is disappearing in the Western society, and that the inflation is a hidden taxation (for the poor, but not for the wealthy” are three separate topics, only loosely related to each other. Biden expanded the staffing and budget of the IRS, to go after wealth tax cheats. Trump is firing a bunch of them, to enable cheating. Biden tried to expand the reach of the CFPB, protecting consumers against predation by the wealthy, while Trump is gutting it. Very different actions, and one is a threat to money and power.

Thorium has 90 protons, so it’s not Th-60 “experts estimate it contains up to 500 times more energy potential than conventional uranium-232” Conventional fission uses U-235. U-232 has a half-life of 69 years, and I’m not sure it’s fissile. I don’t think anyone uses it. It’s curious they mention 233 sites, when Th-233 is one of the isotopes you would find. Could be right, or they misunderstood what finding 233Th sites means, especially if the text is displayed as “233 Th sites”

I think you’re right. With their last post it’s clearer to me what their misconception is. The wire’s length is only contracted in the electron’s frame, not the lab frame, so there’s no reason to expect the result they claim.

If you post off-topic stuff, one possible outcome is that it goes into the trash. Especially if there’s little chance of fruitful discussion on the new subject.

In the lab frame, what is length-contracted? Not the wire, because it’s in the lab frame. The length contraction giving the charge imbalance is the electron frame (the one giving rise to the current)

You’re still misunderstanding the scenario. The number of balls (N) is invariant but L decreases, so I don’t see how N/L can do anything but increase. Same with charge density. The answer to the OP’s question is that we do notice the situation, as I hinted at with my first response. Two current-carrying wires will attract or repel. We call it magnetism, but that’s just the name we give it, since we know magnetism is just electrodynamics that includes relativity. https://physicsworld.com/a/the-invisibility-of-length contraction/#:~:text=Length contraction has never been,in the other wire's frame. “Length contraction has never been directly measured. But its effects show up in the magnetic force that acts between parallel, current-carrying wires. Bizarrely, this force, which is purely magnetostatic, appears in one wire due to length contraction as experienced by the charge carriers in the other wire’s frame. (It’s complicated)” (references are given, for anyone interested)

How would you assess whether or not it’s quality work? You might have to explain what you mean by this. If a woman was chosen because of DEI (the actual meaning, not the GOP caricature) it means the woman is more qualified. DEI ensured she got considered. What constitutes a passing score, and the divisions between grade levels is subjective. Partial credit exists for “wrong” answers.

What happens to the number of balls per unit length (the ball density)?

I would imagine aerosols falling to the surface (which would include the ocean) and then accumulating in the ocean would be measured in years, which is negligible in this scenario. So there should be a layer that has a spike in Be-10 from any short-duration event. If it’s forming a layer on land and later eroded, that’s going to be spread out in time with much lower Be contributions. And the rate need not be continuous if you’re measuring the Be-10/B-10 ratio to get the date.

A perturbation in the electromagnetic field, moving at c, is one way to look at them. Being quantum particles, classical descriptions don’t always cover all of the behavior. (angular momentum being one thing that might not be a property that is obvious from the above description)
