Biological realism of movie scenes megathread?
Are you under the impression that people didn't sleep before beds were invented? That people don't sleep on a floor or the ground?

Exiobiology and Alien life:
It might be interesting to see how these odds were calculated. Or perhaps not, because there are a number of sources for these odds (from creationists) that use "analyses" that are mind-numbingly naive.

Assessing the realism of fictional portrayals of chemistry
Is there a point for looking for realism in cartoons, which exist without having to conform to real-world limitations (other than financial), and looking for realism in parody?

Arizona House Legislature Passes Unconstitutional Bill...
You can cite all you want, but that does not change the fact that courts have made horrendous decisions over the years. Were any of these a case in which a local court ruled that a law violated the federal constitution? I had asked you for such an example. (a peace treaty is not the constitution)

how do you interpret multiplied units?
No, it’s not. m/s^2 is “meters per second, per second” because acceleration is a rate of change of speed. s^2 is in the denominator, which is crucial. Seconds per second is s/s, which would cancel

Arizona House Legislature Passes Unconstitutional Bill...
Do you have a citation of any local judge ruling a law unconstitutional (not in reference to a state constitution)? And yet the 14th amendment was deemed necessary

No guarantee that life that might have existed there is the kind that would leave a corpse.

That’s working so well with abortion rights.

War Games: Russia Takes Ukraine, China Takes Taiwan. US Response?
I think perhaps that a RTS game won't incorporate the phenomenon of "poorly-maintained equipment because the system has been looted by corrupt higher-ups and widespread incompetence/apathy" along with scores of other impacts that can't be programmed in to a simulation. So even if logistics matters it's unlikely that it goes into the level of detail that real people encounter in real situations There are computer games where you just happen to find ammo and 'health' hidden behind odd-looking bricks in a wall, which is great for game play but not realistic at all, though the phenomenon of finding enemy equipment abandoned might be under-represented. Douglas Bader, WWII RAF pilot, gave a talk to a prestigious girls’ school, and was describing the German planes attacking him: "I had two f*ckers to the left of me, two f*ckers to the right" The horrified schoolmistress interrupted with, “Ladies, the Fokker was a type of German aircraft,” to which Bader replied: “That’s as may be, Madam, but these f*ckers were in Messerschmitts.” (Paraphrased. there are various versions of this all over the internet)

Did the American education system did such a poor job at promoting STEM that "Millennials" were less interested in becoming astronauts?
! Moderator Note This has gotten very old. Demonstrate it with actual data, rather than assertion and anecdote.

War Games: Russia Takes Ukraine, China Takes Taiwan. US Response?
Which was what I was trying to point out when I said “There is no moral factor in blowing up images on a computer screen” In a simulation, if there are points for blowing up a school or hospital, you blow it up. That’s not reality, though. IOW, simulations don’t model things completely. It omits aspects of reality. You’re moving the goalposts here. You had made claims that a 15-17 year-old could make better decisions because they had more experience than a “true general” by playing RTS games. Do you think that actual military people don’t do simulations? aka war games? They do. In addition to training that you don’t get with computer games.

Why is there less talk about medicinal herbs, herbal medicines , herbs , mushrooms in west today
I've had difficulty explaining to some family members that e.g. a water molecule doesn't know if it was released in a "natural" or a synthetic process. It's just a water molecule.

War Games: Russia Takes Ukraine, China Takes Taiwan. US Response?
I don't think I did, or perhaps the point was made badly. You're talking about propaganda, which was in the latter half of the post, and has nothing to do with playing the computer games in question, AFAIK. Two distinct topics, and I wasn't talking about the second one.

War Games: Russia Takes Ukraine, China Takes Taiwan. US Response?
Please let's not pretend that a RTS game has any valid relevance to this. There is no moral factor in blowing up images on a computer screen, and no risk to your person for doing anything. If you mess up you might not win the game. That really doesn't merit any discussion whatsoever. I've played a turn-based (rather than real-time) strategy game and the decision to go to war and the details of how you go about that has is in no way preparation for the real thing for any rational adult. I'm really disappointed this has to be explained to anyone. And points to the earlier comment about how nobody would waste ammo blowing up a kindergarten. It is barbaric and demoralizing. There are reasons why the Russians are engaging in such tactics, but it's also one reason why (most of) the rest of the world is united against them. In WWII you didn't have the ability to do precision bombing and avoid hitting civilian targets. Everybody was doing it. That's not the case today.

War Games: Russia Takes Ukraine, China Takes Taiwan. US Response?
I'm not sure "they are committing war crimes so we should, too" is a good strategy. I think you lose support for your cause if there is credible evidence that you're doing that. I think you might stop getting military aid. Do they even have that kind of weaponry (missiles that can travel hundreds of km)? I would be a little surprised if other countries were selling/sending them what would clearly be offensive weaponry.

steam thermal efficiency in the transportation sector
In addition to exchemist's observations, you'd be in a situation like the old steam locomotives you mentioned - an engine but also a place to store the fuel, which you have to lug around with you. Along with the storage container and the fuel delivery system, which are likely to be more massive than a fuel tank and piping. That's an additional drain on your efficiency. That worked for trains, but not so much for other applications.

Stephen Hawking's black hole paradox
The first stumbling block, I would think, is not having a theory. I’m not sure the SSC was going to test quantum gravity

Stephen Hawking's black hole paradox
I don’t think so. It’s a matter of basing it in QM vs extrapolating from classical physics, as they currently do Also nobody observes gravitational effects at the Planck scale.

Solar heating efficiency ?
It depends. If you are just making hot water it’s 60-70%. If you are generating electricity it’s significantly lower.

Nuclear reactor technical discussion (split form War Games: Russia Takes Ukraine)
Meaning it has no place in a technical discussion based on fact. As I pointed out, they pulled more rods out of the core than they were supposed to, As I recall, this was because of a buildup of Xe-135. Had they waited for it to decay, the situation would have been quite different.

The second coming of Donald Trump: Can he become president again? | 60 Minutes Australia
I'd say it does matter, because by and large it's one party is repeating Kremlin talking points and subverting democracy, while the other isn't. That there isn't a clear distinction on some aspects of government, that doesn't extend to all aspects of government. These are the acute effects, but I worry about the long-term. I think we will be seeing the effect of TFG for some time, as things bubble through the courts. Roe v Wade is likely to be gone soon, and that won't be the end of it. All because of justices he appointed.

Precision - The Magic Bullet
While I would hesitate to call a nuclear weapon a precision instrument, there are treatments in medicine that you can describe as precise. Proton therapy, for example. You send a beam of protons at a tumor, and tune the energy so that the protons will deposit the bulk of their energy in the tumor rather than the healthy tissue, so you disrupt the tumor. (They have a proton therapy center at TRIUMF, where I did a postdoc)
