https://en.m.wikipedia.org/wiki/Ampère%27s_circuital_law H is useful for calculating the flux density in magnetic circuits with different magnetic materials. I find it especially useful when working with permanent magnets. http://www.electronics-tutorials.ws/electromagnetism/magnetic-hysteresis.html When using Hopkinson's law for magnetic circuits, B is the "current density" and H is related to the voltage.

Why concave magnets? I guess the result would be a driven harmonic oscillator. https://en.m.wikipedia.org/wiki/Harmonic_oscillator

Plastic rings filter holders source you may suggest, please ?

The examples you show are aluminum and shouldn't corrode. -
Or old, less important information gets overwritten. In 300 years, we'll probably be able to plug in an external flash drive anyway.

Why are we humans and not robots?

Which definition did I change? -

You would need to define "intelligent decisions" or "awareness". My computer knows its name, its location and can run selfdiagnostics. Even my toaster is "aware" that it is on or off and can make an "intelligent decision" about when to pop out the toast. -
Citation needed.I know I achieve far more with other people if I am not hateful towards them. Hate tends to shut doors, while respect and dialogue opens them. Even in the rare cases violence cannot be avoided, hate is unreliable and needlessly destructive. Did Jesus use hate or love to spread his message? "Going against established order" does not require hate in any way.

Amusing. The scary part is that you might not even be (aware that you are) trolling.

What is the difference between a computer and an AI? It is a gradual transition and every computer has some intelligence. At what point would it stop being ridiculous? Why should we even draw a line? I can't find your definition on Wikipedia, which seems to focus on antisocial behaviour and lack of empathy. Why don't we stick to the common definitions of words?(Link: https://en.m.wikipedia.org/wiki/Psychopathy ) -
You can describe it in words (and perhaps put a link to the youtube, as illustration). If I saw it correctly, it was a butternut pumpkin rocking back and forth in an oven. Is that correct?

If math is about memorisation, the teacher is definitely doing something wrong. It should be the subject that needs the least memorisation. I don't have this experience, but we also don't have standardised tests.

Your computer posted this message of yours for you without personal gain. It even presented you the information in the best way it can, all for your convenience. Nearly all computers and robots only serve others, and not themselves. I didn't know about the selfless psychopaths. My argument obviously doesn't hold for those, but neither do they pose a disadvantage for social groups or do they have an advantage due to selfish behaviour, which is what I reacted to. -
Math was one of my favorite subjects, second only to physics. I enjoy finding the solution. I still enjoy mathematical riddles. I liked math independent of the teacher (I was the teachers favourite anyway). I like it for the problem solving, but also for the math on its own. I guess being good at it helped to enjoy it, but enjoying also helps to be good. I agree with the sentiment that everyone should get it in sufficient amounts to be able to build on it. I may have known I would do something with math/science at age ten, but others only decide after secondary school (age 18). A former colleague of mine only decided to become an engineer after doing something with languages in secondary school. Now he has a PhD in engineering. I doubt that would have been possible if he hadn't had any math among those languages. Moreover, even psychologists need a significant amount of math. I don't think focussing only on the problem solving aspect would work, since it is harder and can only be done well after a solid foundation is established. It usually comes at end of the chapter, often in extras, and is horror for many students who struggle with the basics. What could be done is closer collaboration between math teachers and eg science teachers. There are, however, some subjects that could be handled better. I feel we spent eg too much time on solving all kinds of complex integrals. All the integrals I encountered as engineer can be divided in three categories: - polynomials: by far the most frequent and easy to solve - something that can be found in the list of integrals on Wikipedia - something else, which is easily solved numerically. It would be much more useful to spend more time on composing the integral corretly.

Could it be that the internal pressure inside the mercury, caused by surface tension, is large enough to keep it from boiling.

Death being final impacts our value as human beings

Clearly that doesn't work out for you, so why not broaden your view? Do you think your condition is physiological, psychological, or a combination of both? -
Einstein didn't like quantum mechanics because "God does not play dice". He was also wrong about that. The quote you give is also easy to disproove, since I don't feel a thing when reading gospels (except boredom because it is poorly written fiction).

I seriously doubt I would get aroused by a stripper. I think I would be too uncomfortable. Don't worry about it.

"Who sees the image in the brain and interprets it?" The brain does. Similarly, a computer thinks, therefore it is. "My aim was to establish the role of genetics in social interactions and I gave to examples where the genetic predisposition was important to the development of social personality characteristics." And by doing so, you highlighted (one of) the reason why humans think they are special. "However, it is important to note that psychopaths may be successful in having no empathy or compassion except for themselves and therefore can imitate human qualities in a more complex but similar way to a computer." I already gave an argument how psychopaths are actually less like robots or computers. Computers are generally not selfish and take the well being of others into account. Do I really need to find a reference to proove that a solitary mother is unlikely to raise a child, which is virtually helpless for a decade, in an environment full of predators? Moreover, since human children die quite often without modern medicine, she would have to feed, raise and protect multiple children simultaneously. -

Why limit yourself to your own experience? -
It's the Lorentz factor. Specifically, if you are moving at the speed of light (not possible), no time passes for you, so everything moves infinitely fast.
