“Spontaneous” is actually the correct word to use here, using its definition in statistical mechanics.

Cephalopod eye transplant!
I wouldn’t be surprised if the brain could figure out how to use a cephalopod style eye, especially if it was given young.

Basically.
They slowly decay as hawking radiation, but there’s nothing you can do to speed up the process.

I think I have had an instructor put a mirror in the pool before lol
- Comment on Is possible to learn to swim, just by reading a lot about it? 1 month ago:
I doubt someone who has only ever read about swimming could do it in deep, cold water. But they are talking about taking it to a swimming pool to practice. I think they’ll be fine.
- Comment on Is possible to learn to swim, just by reading a lot about it? 1 month ago:
Probably. Take it to the shallow part of a pool (where you can stand up if you need to) and practice until you are comfortable trying more.
Also, watch some videos. I think it’s easier to learn something like swimming by watching others than by reading about it.
- Comment on call of the void 1 month ago:
It’s a tool without a use case, and there’s a lot of ongoing debate about what the use case for the tool should be.
It’s completely valid to want the tool to just be a tool and “nothing more”.

But can electromagnetism at all emerge if the quantum mechanics dont exist to emerge things like magnetism and some of the behavior of electrons?
Short answer: yes.
Technically the world can’t exist without all of its physics. But that’s kinda backwards from how you study it. Quantum mechanics isn’t “more correct” than classical mechanics, it’s more that it’s “more detailed”.
If you want to model an electromagnet, an electronic circuit, light (in most macroscopic situations), how permanent magnets interact, electrostatic situations like how static electricity makes your hair stand up, lightning, the magnetic fields of celestial bodies like the Earth and Sun (they are big electromagnets), etc. you will use “classical” electromagnetism (meaning Newton’s mechanics, possibly with Einstein’s modifications, and Maxwell’s equations).
If you want to model material science situations, like determining what material to make a diode or transistor out of, or if a given material can become a permanent magnet, you will likely need quantum mechanics to help model the interactions of electrons on the atomic scale. The section on Wikipedia you were looking at is about this kind of material science. You do this by combining the same “classical electromagnetic” equations with Schrödinger’s equations for quantum mechanics.
- Comment on Gravity 1 month ago:
diamagnetism, paramagnetism and ferromagnetism can be fully explained only using quantum theory
The magnetic properties of certain materials (e.g. why an unmagnetized piece of iron sticks to a magnet of either polarization), the way permanent magnets work, is best explained by quantum mechanics.
However, the electromagnetic force itself doesn’t “arise” from quantum mechanics, and you can explain things like electromagnets quite will without considering quantum mechanics.
Usually you take the “classical” formula for a force and to inform your quantum mechanical model of particles, and that’s how you can arrive at things like deriving how permanent magnets work with the help of w quantum mechanics.
Generally, a lot of material science and chemistry is inherently quantum mechanical because the way atomic orbitals and molecular bonds work is heavily quantum mechanical.

Fundamental means it cannot be explained by being caused by something else.
Fundamental force means we expect a carrier particle to explain it (for gravity that’s the Graviton, although it hasn’t been detected yet).
electromagnetism is caused by quantum phenomena.
Not even remotely true.
What is the cause for spacetime or quantummechanics? Idk but somehow they don’t make it on the list of fundamental forces.
Quantum mechanics is mostly that statistics is more complicated than we all thought . Seeking a cause for spacetime is interesting. It might be relevant to mention that there is a fundamental particle that imparts mass, which we call the Higgs Boson. I guess that could make mass and inertia something of a “fundamental force”.

Windows is designed to work on a very wide range of specs, so older devices as well as low-end newer devices should be able to run it.
That’s even more true about Linux. Many popular distros can be run on a raspberry pi, a 20 year old MacBook, or a state-of-the-art gaming desktop.
It’s less true about macOS because Apple has more control over the hardware so they can be pickier. Mobile developers also have more control over the hardware and can be pickier, although that’s less true about Android than iPhone.

- Comment on If we replace most plastic with a non plastic alternative and would that really be better? 2 months ago:
If you use reusable bags, bottles, and other containers, that’s way more sustainable than any single use product.
But using paper is still better than plastic, and yes, trees can be and are sustainably farmed in many parts of the world.
I have seen some shifts away from plastic. For example, Apple seems to have removed almost all if not all plastic from their packaging, replacing it with paper.
