Did Trump Steal the 2024 Election?
Oh sure, a lot of people in Europe have compared Trump to Mussolini for quite a few years. In fact some of us even compared the UK's "Mini Me" version, Boris Johnson, to Mussolini as well, though he was never in Trump's league of course. Trump is behaving like a copybook dictator taking over a democracy: going for the justice system, the electoral system and the media. But El Douche makes him sound like a S American dictator rather than Italian - which is better in a way as S America has had more than its share of fly-by-night, tinpot dictators. Anyway, it's a very apposite nickname.

I very much like “El Douche”, combining as it does the sinister with the contemptible. Is this a thing now in the US, or have you just invented it?

REVIEW INVITATION : Awakening the Sleeping Giant: Rediscovering Archimedes' Density Method for Fingerprinting of Multicomponent Alloys
No, that paper is behind a paywall, so not acceptable here. Kindly explain how you overcome the objection we are raising, here on the forum, in your own words, with reference to the diagram posted by @John Cuthber.

Gravity
Which theory are you talking about? Newton’s, or Einstein’s? Or both, perhaps, if you are a Flat Earther? 🤪

compounds for 12yo's ❤️ molecules for 12 yo's
The smallest would be a monatomic molecule, for instance any of the inert gases (Helium, Neon, Argon, Krypton, Xenon). These atoms don't form chemical bonds at all, or only with great difficulty, so as substances they are composed of single atoms. So in this case, the atom and the molecule are one and the same.

compounds for 12yo's ❤️ molecules for 12 yo's
A molecule is a group of atoms joined by chemical bonds, constituting the smallest complete subunit of a chemical compound that can take part in chemical reactions. In the case of giant structures there is no such subunit. You could almost say that, with a giant structure, the whole structure could be thought of as one giant molecule, but even that would not be entirely right as it has no fixed size: it's size simply depends on how big the entire crystal is!

Who will be the first to go?
Hmm, could be. From what I read about him in the Financial Times, Musk is a hardcore free-market tech bro, thinking that most functions of the state should be outsourced to private enterprise IT companies to obtain efficiencies. The full "Robocop" scenario, in fact! To me - as to the makers of "Robocop" - this is a vision of a dystopian hell, with the populace fed a diet of comforting lies and cheap consumerism ("I'll buy that for a dollar"), while IT corporations make decisions about society based solely on profit-driven self-interest.

Actually this is not correct, because not all compounds are molecules. There are also giant structures, both ionic (such as common salt) and covalent, (such as quartz). These compounds are not molecular in nature but are indefinitely extended arrays of atoms, with regular repeating units that correspond to the formula of the compound: NaCl i.e. one Na+ to every Cl-, and SiO₂, i.e. one Si atom with 4 covalent bonds to every 2 O atoms with 2 covalent bonds each. (Metals are also a 3rd type of giant structure, but these are generally not chemical compounds.) But yes, you are right that oxygen and nitrogen are both diatomic molecules: O=O and N≡N. Carbon dioxide is a triatomic molecule: O=C=O. (Oxygen also forms a triatomic molecule, ozone, but that is very reactive and not good to breathe at all - though it does find some application in disinfecting public swimming baths.)

That sounds about right. Meanwhile Musk, famous for his impatience, will become more and more frustrated and angry. And then a fuse will blow and he’ll storm out. Probably.

Force on the rocket in the rocket problem
I don’t follow you here. Sure, the absolute value of the momentum depends on the choice of inertial frame, but the change in it does not. Just as the velocity of a thrown cricket ball is different as seen from the ground vs. a passing car, whereas the change in velocity when it is caught is the same for both frames of reference. Or am I missing something?

Who will put Musk’s recommendations into effect, then? Trump himself?

Help with examination work of eggs vs salts
I found this which may help to explain: https://en.wikipedia.org/wiki/Egg_white. esp. this passage: "Copper bowls have been used in France since the 18th century to stabilize egg foams. The copper in the bowl assists in creating a tighter bond in reactive sulfur items such as egg whites. The bond created is so tight that the sulfurs are prevented from reacting with any other material. A silver-plated bowl has the same result as the copper bowl, as will a pinch of powdered copper supplement from a health store used in a glass bowl. " I believe there are disulphide and thiol (-SH) groups in egg albumen which will react with Cu and Ag. The reason why Cu and Ag bond in this way while Group I and II metals don't will be to do with the nature of the bonding. Gp I and II metals will only form fully ionic bonds, whereas Cu and Ag can form bonds with more covalent character, possibly with some π-contribution in the case of a 3rd row element like S. I can't remember much about this, though, so maybe someone else can help.

REVIEW INVITATION : Awakening the Sleeping Giant: Rediscovering Archimedes' Density Method for Fingerprinting of Multicomponent Alloys
I'm amazed this is still going on. A pattern has emerged. A simple question is asked - and the answer is several paragraphs of verbiage, dancing around the issue and introducing newly invented terminology, but not answering the question. At the end of the day, no answer has been given to explain how, given that, as @John Cuthber and others have pointed out, a range of compositions can have the identical density, one composition can be positively identified without any extra information being provided. Unless a succinct answer to this can be provided, one is forced to conclude this is all bullshit.

What does it mean for the US now? Like what does second term of Trump mean for the US now?
As far as I know, there is no workable system of democracy other than electoral democracy. So I think your distinction is of little significance in practice.

Why Biden doesn't broadcast nuclear threats for Russians and for China?
Because sabre-rattling is a sign of insecurity and makes war more likely, not less. Everyone knows the USA has the power to destroy Russia. Talking about it is cheap. What gets the Russians’ attention is demonstration of resolve. The re-election of Trump shows that the USA lacks that resolve. I share your hope that Putin may eventually get deposed by internal revolt, but that won’t come from talk by the US president. In fact, now that Trump has been re-elected, Putin will feel quite safe from any threat from the USA. Trump is on his side.

Cuban Missile Crisis Hypothetical
No, because the tense of the question is wrong for that. It would have read “how many missiles would have been launched” , if it was a question about 1962. Asking how many the US “would launch” places the hypothetical question firmly in the present/near future, to my mind.

Resistance
I'm an outside observer from across the Atlantic but it seems to me the most vital thing is to be alert for and challenge attempts at state level to alter the electoral process and the electoral arithmetic by unfair means. And also to oppose by means of vigorous campaigning any whisper of attempts to bypass the 2 term rule. I think it more than possible that Trump and/or Vance may try this, e.g. by fabricating a "state of emergency" or one of the other methods favoured by autocrats and one party states. I would agree there is little point in opposing specific policies: one has to watch them fail and then allow their proponents to reap what they have sowed. But the undermining of the country's system of democracy cannot pass unchallenged, as that easily becomes a one way street.

What are resources to prevent school shootings and mass shootings?
Comparing rape statistics between countries is a poor measure for estimating violence in society, due to the different legal definitions and differences in willingness of victims to report it. There is some discussion of the issues here: I quote one paragraph relating to Germany, as you mention it: https://worldpopulationreview.com/country-rankings/rape-statistics-by-country " Sweden's seemingly oversized rape rate is perhaps the best-known example of this scenario. During the years 2013-2017, Sweden averaged 64 reported rapes per 100,000 inhabitants—a rate that tied for the highest in Europe. However, when the data was examined, it became clear that Sweden's high numbers were fueled in large part by Sweden's broader definition of rape and more inclusive reporting rules compared to other European countries. When the data was recalculated using Germany's narrower guidelines, for example, Sweden's average reported rapes per 100,000 people fell from 64 to 15, a decrease of 76.56%."
