Problems with negative pressure and vacuum energy
And in the quote you provided, it says P>0 So how do you get from that to saying it’s negative?

How best to start including men who are victims of abuse by women into the public discourse (Johny Depp vs Amber Heard)
No link, and nothing about these statements point to him being the victim abuse. They more likely refer to the defamation from her de-facto accusation that he abused her, which is what the trial was about. Especially "the jury gave me my life back" which sounds like the vindication of libel being confirmed. IOW, it's equivalent to "she lied, I was impacted by that lie and the jury confirmed that" which is not in any way acknowledging or suggesting he was the victim of domestic abuse.

That Depp was the subject of abuse. I can't believe how obtuse you are being. I have no skin in this particular game (establishing that Depp was a victim of abuse, and no, being defamed is not automatically the same thing), so I will bow out. If Depp wants to pursue charges for being abused he is free to do so; unlike many victims he's not trapped by lacking resources to break free of his alleged abuser.

It's not a fact just because you say it is. That's not what a fact is, that's an assertion. Maybe it has merit, maybe not. One should investigate You were asked to provide evidence to back up your assertion. You have not done so. All you've done is repeat the assertion, which does not make it a fact.

She admitted to hitting him. "Heard has testified she struck Depp only in self-defense and to protect her sister, Whitney Henriquez." https://www.nbcnews.com/pop-culture/pop-culture-news/key-allegations-johnny-depp-amber-heard-trial-rcna30147 Both she and Depp have alleged the other one was the aggressor, but since the trial wan't about domestic abuse, this is literally a "he said, she said" situation. Either one, or both, could be fabricating events and/or circumstances. (If their testimonies are in conflict, at least one is doing so) So once again, do you have evidence of your claims, and if you do, please post it rather than just repeating the allegation.

Power?
For a torque to become energy (i.e. do work) it needs to happen through some rotation (analogous to a force exerted through a displacement). The angle is unitless, but again it's a dot product (the torque is a vector but typically the angle can only be with the same handedness or opposite, which tells you if you add or subtract energy)

I'm not sure what I have said that leads you to believe that I lack empathy towards any victim of abuse. I will note that others have asked you for evidence of JD being such a victim, but I don't see where you've provided any.

The pen is blue
Most serious science that is published does not generate income for the author(s). On the contrary, it costs money to get published in scientific journals. Popular science writing can generate some modest income, however. But for good writing that lets non-scientific people understand scientific things. So if you just want to get your ideas out there, it's as Bufofrog says - publish it here. But keep in mind that you will have a critical audience. If you don't want that, start a blog somewhere and turn off comments.

The definition of pathetic is "arousing pity." Pity is "the feeling of sorrow and compassion caused by the suffering and misfortunes of others:" You feel sorry/compassion for JD (at least, that's how your posts come across) - that his name was besmirched and he was blacklisted, i.e. he had misfortune. Thus, you feel pity for him. Seems pretty straightforward to me. The situation was pitiful.

Yes, but as you seem to be expressing pity for him, you seem to agree that this is pathetic. But the lawsuit was based on an Op-ed published in the Washington Post. https://www.washingtonpost.com/opinions/ive-seen-how-institutions-protect-men-accused-of-abuse-heres-what-we-can-do/2018/12/18/71fd876a-02ed-11e9-b5df-5d3874f1ac36_story.html a jury found Heard liable on three counts for the following statements, which Depp claimed were false and defamatory: (1) “I spoke up against sexual violence — and faced our culture’s wrath. That has to change.” (2) “Then two years ago, I became a public figure representing domestic abuse, and I felt the full force of our culture’s wrath for women who speak out.” (3) “I had the rare vantage point of seeing, in real time, how institutions protect men accused of abuse.” I'm supposing it's the calling out of "domestic abuse" that defamed Depp I didn't follow the trial, so I'm not sure why she was held liable for three counts. I'm also confused as to what the connection is to her allegedly being an abuser and predator.

What is a living individual and is it naturally universally mobile?
Sorry, what's your point? Stringing together buzzwords is not science. Then go ahead and present evidence to falsify it. What is this mechanism and how can this be tested? What do you mean by individuality? There's a definition that refers to uniqueness, and another that refers to the uniqueness specifically of people and how they express themselves. If you can quantify the uniqueness of something, it would depend on how many different properties, aspects or qualities that something has. Multicellular life has more properties that can be different than if you consider single cells, just from the number of ways you can configure the cells. But you can't use the other definition in this regard; that would be the fallacy of equivocation. How one chooses to express one's self requires a brain. If you think this is being applied to the first definition, you need to back this up with some citations/links.

Power?
Torque is a vector and energy is not. The units for energy and torque are equivalent, but the convention is that torque uses the units N-m rather than joules, because torque is not energy. This is correct, and is described by the work-energy theorem. W = integral of F.dx (dot product, i.e. due to the component of the force in the direction of displacement) F = ma = m dv/dt so we are integrating m dv/dt dx Let's drop the vector notation and look at the components (i.e. we've done a dot product) We rearrange this to be m dx/dt dv which is mv dv Integrate and you get W = 1/2 mv^2, evaluated at some initial and final v. Work is the change in kinetic energy (note that capiert has a tendency to use equations while ignoring any constraints and initial conditions, and try to apply those equations in general, which leads to problems. Also the use of non-standard terminology, labeling, and symbols) It's neither "tradition" nor "brainwashing" It has a very sound basis (time translation symmetry) and protocols on how to apply it. If you ignore those protocols, of course, you get the wrong answer. We don't kick things out because a few people fail to understand them. And mass-energy is famously not a conserved quantity. ∆KE = KEf-KEi i.e. KEf-KEi is the change in kinetic energy, not the kinetic energy. This is a very important distinction. Here is an example of using a specific equation and trying to apply it in general. Power applies to more than the situation of an object falling under gravity, so one cannot make a general claim that force is weight, since there are other forces. If you use weight, then the equation will only apply to a falling object, and also only if you can assume that this is a constant force.

US-Roe vs Wade overturned
Who is they? My teachers? I have no idea if my teachers read the Bible. They certainly didn't write it, and I can read it myself. I cited some entries above. You can read it for yourself. WTF are you talking about?

Gun control, which side wins?
The amendment as written isn't about a civil society, it's about having a militia that can be called up for defense of the country, written in a time when militia members often had their own rifles. At least, up until the Heller decision, which made up a right to own guns for personal protection.

US-Roe vs Wade overturned
I don't need to read the Bible in order to do science or state a scientific position. What's your point? (the analogous position would be to make a scientific claim that's not based on science. Where is this happening?)

What is a living individual and is it naturally universally mobile?
Could you have DNA-based life? Sure. Would you get species that are exactly as they are on earth? No. There are too many variables that would have to be reproduced exactly for this to happen. You're just making stuff up here, using buzzwords

US-Roe vs Wade overturned
Which religion, though? What little the Bible has to say indicates that abortion is not murder (Exodus 21:22; if you cause a miscarriage the penalty is fine, not death, which is the penalty for murder), and a couple of passages which indicate that life and breathing are coupled. In Numbers it describes how to cause a miscarriage (i.e. an abortion) in an unfaithful wife. The problem with the rabid anti-abortion Christians is that they don't read, or conveniently ignore, the Bible.

Are there two kinds of reflection of light?
This is unclear, at best. Light reflecting from a smooth surface tends to become linearly polarized; at Brewster’s angle it is completely polarized, parallel to the surface. There’s no circular polarization involved (symmetry should tell you this - why would one handedness be preferred?) Linearly polarized light can be represented as a superposition of right- and left-handed circular polarizations, but when you say that light is circularly polarized you are implying one handedness is present. There are left- and right-handed polarization, but “to the left” or “to the right” has a different implication. And what is the 90 degree rotation referring to? Light reflected normal to a smooth surface will change handedness (but only at normal incidence) https://en.wikipedia.org/wiki/Circular_polarization#Reflection
