I’m saying if you lift something with a magnet, you are supplying the energy, not the magnet. It’s not different, conceptually, from attaching a chain to something and lifting it. The chain is involved, but it’s not supplying the effort to lift the object. The chain doesn’t have a store of energy that does the lifting. It doesn’t matter how convoluted or clever a scenario you come up with. The energy to do the lifting (which is what work is, in physics - the energy supplied by exerting a force through a displacement) comes from somewhere else.

Dodge? You’ve been told that the work is done by external, mechanical means. All dipole magnets act like a current loop (permanent magnets, too) and the force on a current is IL X B. That’s a cross product - the force is perpendicular to the current and external field. Work is a dot product of the force and displacement. The work is in the common direction of the force and displacement. Since the force is always perpendicular, this dot product is zero. There is no work done. No energy comes at the expense of the magnetic field. It doesn’t matter if the magnetic field is from a permanent magnet. It doesn’t change if you try coming up with some clever configuration. The work is always mechanical or electrical. The magnet isn’t depleted, which must happen if the magnet is doing the work, and this would happen pretty quickly if that’s what was happening.

Do you understand that “fixed” is only an approximation? There is no such thing as a perfectly rigid structure. Which means that the mechanical structure flexes. There are mechanical forces, and they act through a displacement, i.e. they do work. Because that’s involved in magnetic attraction. You have to understand a bit of physics to appreciate the answer. If you don’t, then the answers might look like obfuscation or irrelevance. But you have an obligation here, because demanding an answer that involves a couple of semesters worth of physics, without having that knowledge, isn’t reasonable.

Is the magnet hovering in space? I don’t think that’s happening. (Further, what happens in the metal? You get an eddy current. The force doing work there is electric, not magnetic.) The work - the energy input - is not the magnet. It’s something else. Magnets don’t get energy depleted by being used. They are not the source of the change in energy of the system.

Just like with any other product. Trump markup. That’s the point of this grift. Or there is no copyright attached, which would be the case for the Bible. I’m shocked, shocked, that deceit is going on here. A scam? Involving Trump? The deuce, you say! </s>

I’m saying you aren’t looking very closely at what happens. A magnet does not magically move into place to lift something, and when it is moved, work must be done in doing so, and during the lifting process. By the system or person moving the magnet. The magnet is an agent of transferring the force you are exerting, but the work done is by you, not the magnet.

The work done is provided by whatever or whoever is holding the magnet. The magnet does not move into position where it can lift by itself.

Magnets are another example of redirecting; magnetic forces are perpendicular to motion, so they do no work.

! Moderator Note Countries not banning it is not evidence of safety, the information about adverse reactions including death are easily found with a search, and it is not for you to set the limits of what can be consumed.

So the input is where the work is done. And the work will be done by you in moving the magnet - it takes more effort to move a magnet in the presence of another than it does in free space. That’s you doing work, not the magnet.

Magnetic forces don’t do work. If you built this, you would see that it doesn’t run on its own. If you stop cranking, it will cease motion.

The work in this system would be provided by whatever is turning the input rotor. Nothing inside the device is supplying energy; there are only losses to be found there.

! Moderator Note This is very much the forum for getting testable predictions. It’s a requirement. Teasing that you’ll get to “the meat” is something we’ve seen before, and it never pans out. You’ve not given any indication that this will be different, and if you don’t deliver (and soon) the thread will be locked. A journal? With peer review? Are you going to make preprints available? I don’t understand. What are “these problems”? How are they growing larger? How do you conclude that standard physics won’t solve the problems? Cosmology isn’t a huge slice of physics, though it’s more visible (as it were) than other areas.

The second side was not brought up in the OP, which was simply asking if there are ways to password-protect files.

I’ve had documents sent to me that were password protected. Microsoft docs and pdf files

I hope H didn’t stand for “Hugh”

To me a shortened version of a first name is not a nickname. i.e. I don’t consider ”Tom” to be my nickname. Nicknames I’ve had are Swanny (grade school) Stouffer (college), Puft (navy OIS), none of which are gender-specific. SNL had a series of sketches about gender-neutral nicknames. The lead character was Pat, and nobody knew their gender. Also mentioned are Terry and Chris, and homophonic names like Frances/Francis, Jean/Gene

It’s random - any pick has the same odds of winning. Picking unpopular number increases the odds that, if you win, you will be sole winner, or at least have to share with fewer people, as your quote says. So the expected payout increases.

Animals (specified in the OP) ≠ organisms Plants can be male & female Where does the other genetic material come from if the individual self-fertilizes? If there are two, then you’re doing what sexual reproduction does, so it it’s an advantage, then it’s an advantage. And AFAIK most hermaphroditic animals are invertebrates so there might be some limits on that mode of reproduction.

It describes a magnet in terms of the torque the magnet would feel in an external field A magnetic dipole (e.g. a bar magnet) with moment u in a magnetic field (B) feels a torque of u X B (u is a vector) The magnetic moment of a wire loop with area A and current I is u = IA (with a direction given by the right-hand rule)

Genetic diversity. You’re getting genes from two different individuals each generation, or possibly each instance of mating.

There’s no fixed reference, so how can you say the sun is moving at all? Or are you referring to the green crescent, which is due to an internal reflection in the lens? That moves because the camera is moving.

I think it’s “perturbed” and it’s from pointing to issues that we already know about and account for as if they are unknown, and somehow a problem. You might be befuddled by the ramifications of a finite speed of light but I assure you that others are not.

(multiple threads merged) How is your idea testable/falsifiable? What specific predictions does it make?

In physics we use instrumentation when it’s needed, which avoids the issue. Eyesight is exceedingly nonlinear and not easily calibrated. In areas where eyesight is used it’s generally where delay issues have no impact. None of this is unknown, nor unaccounted for.
