I didn't say everyone can control all emotions. I'm also no psychologist, and I don't know why other people can't control theirs. I guess my realisation that emotions are nothing more than a bunch of chemicals helped. I don't think stammering, Tourette's or anorexia are emotions, though. I don't know about phobia's, but I guess my fear of heights or public speaking weren't "real" phobia's, just the regular non-pathological kind of anxiety.

Nonsense. I have chosen a long time ago never to be angry or stressed, and I haven't been angry or stressed since. I used to fear heights, but decided not to a while ago, and now when I cross e.g. a rope bridge 100 m high, I don't even feel a thrill.

You could use a propagating electromagnetic field, such as a laser or a focused microwave beam. I know of no way to trap a quasi-static magnetic field, short of a ferromagnetic core (which isn't perfect), or superconductors on the outside. In retrospect, the superconductor thing might not even work, because induced currents in the superconductor would counteract the magnetic field.

In the examples given, the values for single words range from 38 to 94. Even if we assume homogeneous distribution that gives a chance of 1 in 60 for two random words to have the same value, or 1 in 20 if you include consecutive values. It isn't difficult to come up with thousands of pairs of related words, 5% of them will either have the same value or consecutive values. In reality, the chances could be even higher. Now put the words in groups of 10 related words. I'm too lazy to do the math right now, but the chance of two of them having the same value is going to be close to 100%. You'll even find triplets and perhaps quadruplets. In conclusion: there is absolutely nothing strange or peculiar about this. It is simple statistic certainty that a lot of these combinations exist.

Not sure what you are trying to do. That's just a picture of an electromagnet.

It is fairly simple: if you want to trap the magnetic field, you need something to trap it in. That something is going to be more complex and more expensive than a wire. Or could you use a focused electromagnetic beam, such as a laser.

Right. There is also (a lot) more empty space than matter in a solid piece of lead, to illustrate how pointless the concept of a microscopic vacuum is.

Ok, so I guess you refer to resonant inductive coupling. I don't think there is much sense in some contraption to trap the magnetic field. Simply using wires is going to be much simpler and more efficient. You might also be interested in laser power transfer.

Are you talking about wireless chargers? In that case: transformers are pretty efficient and "carry AC current over a magnetic field".

On top of all that: a wave doesn't go up and down relative to the wave.

Going faster than light would yield imaginary time. I'm not sure how to interpret that, but let's just say it is generally considered impossible. Someone going at the speed of light (also impossible) would experience nothing, as no time passes, ever. The universe would instantly end as far as that person knows.

What do you mean by "carry an AC current" in this context?

No, because magnetic field lines need to be closed. It could only work if your shape closes in on itself, and even then there will be stray field lines. I guess you could create a field in a closed space surrounded by superconductors, which expel any magnetic field. Even then, the shape would need to be a thin toroid to be approximately equal throughout the whole shape.

Obviously the correct unit for ordering posts is meter. Try ordering 400 m of posts next time, if only to see what they come up with. It would be silly and confusing, but it would not be wrong . Except perhaps the terminology of "deliver", but my English is insufficient to make that call; in Dutch, it would work.

Air drag will slow it down considerably, so it won't come out the other side. Your object would also melt. However, if you managed to pull the tunnel vacuum, and you manage to avoid the object hitting the sides of the tunnel, your object would get close to the south pole. However, the south pole is 2,835 metres above sea level, while the North pole is at sea level, with the ice only a couple of metres thick. This means that your object would be almost 3 km short. Reversed, dropping an item in at the South pole, it would shoot out the North pole at considerable speed.

('"#A#"') I'm pretty sure the first bacteria didn't have any beliefs. ('"#B#"') You didn't invent it. You might have invented the word, but the concept is not particularly new. ('"#C#"') This should be in philosophy.

Vacuum is zero pressure. Pressure is a statistical, macroscopic property. It is meaningless to talk about pressure (or the absence thereof) on the scale of particles.

The noise probably comes from stick-slip. Removing or sufficiently reducing static friction solves the issue. This could be done by adding ball bearings, oil, layer of air, magnetic levitation or possibly changing the material to low friction material such as Teflon. Changing the load and/or the speed could also help. Perhaps surprisingly, increasing the dynamic friction can also help (because it is the difference between static and dynamic friction that causes stick-slip), which can be done by roughening the surfaces. The squieking noise will probably be replaced by grinding noise, though.

Not sure what you mean without figure. Are you referring to the mechanism that converts shaking motion to electricity in some flashlights? There are plenty of ways to convert mechanical energy to electricity using magnets. All of them require you to put in more mechanical energy than the electrical energy you get in return.

It would be unethical not to talk about ethics.

Simply postponing death by a couple of years is not a problem, as long as we remain productive for sufficiently long. This condition seems trivial since we are already so productive that governments have to invent pointless jobs to keep people occupied. If we cure ageing completely, we will need rules for child-bearing to prevent overpopulation. E.g. to get a child you would need to commit yourself to be euthanized a couple of decades later. There could also be a waiting list for a "child-bearing permit" to replace the people that die without having procreated. I think we need to be very strict about not allowing such a permit to be transferred in exchange for money, as that would lead to all kind of horror-scenarios.

Posts and panels aren't conventional dimensions but "number of something", which is in general dimensionless.

cons: - even really strong magnets don't magically create energy: you can only generate as much energy as you put in, less since you cannot have 100% efficiency - powerful magnets use rare elements and are not renewable - mining these elements causes environmental harm - certainly doesn't make any sense

Of course you can have a parabola of velocity vs time. Nobody is talking about infinite graphs here, otherwise it would make no sense to calculate the arc length, which would also be infinite, regardless of anything else.

Good video about it
