I spent a few $1000 on the computer, I’ll spend $100 more to make it look fancy

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.

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 and a lot of common electric circuits (until you need a transistor) quite well 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”.

Supporters seem to be under the impression that companies have a “sever.exe” file they purposefully don’t provide players because they’re evil and hate you.

There is some truth to this

They could also be contracting out matchmaking services to a third party and don’t actually do it in-house. Software development is complex and building something that will be used by 100,000 people simultaneously isn’t easy.

There is some truth to this too.

Making an MMO maintainable by the userbase might be complicated. But way more common are games that could easily have LAN based multiplayer but the company decides not to add it, or even singleplayer games that require an internet connection, just so the company can put limits on how and when the game is played.

That’s kinda the way of the world in general unfortunately.

They want to be a sport and betting on high-level sports is quite common.

I think you mean grizzly bear. Black bears are usually more timid, although I still wouldn’t try to mess with one.

I’ve been working on my own macOS tiling window manager inspired by Gtile for gnome. I’ll probably put it on github at some point.

Tbf when they do change to pride logos everyone is quick to call it hollow virtue signaling

Hydrophobic coating loosely means a thin water proof coating on a material that otherwise isn’t waterproof.

Example: the previously mentioned popcorn bags are paper based but with a thin plastic based coating. (Historically we used to use wax for this kind of thing but in the modern day it’s almost always plastic)

Not that containers made of glass, ceramic, or metals that don’t corrode don’t need and typically don’t have hydrophobic coatings.

I think there’s an aspect of having it generate a train of thought helps it generate better answers.

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.

It’s still there, buried in the settings. TBF I wouldn’t expect them to remove it, because some people probably do use it.

Rumble has been basically a variant of a traditional speaker in many devices for a while now.

Also it can still heat up, although it might not be as prone to burnout as a motor.

HDDs consist of a metal disk spinning very fast with a magnetic needle held very close to it. Enough of a bump and the needle can run into the disk, potentially destroying both needle and disk in the process.

Honestly services like Blue Apron help with this. It’s more expensive than buying your own groceries, but still cheaper than eating out. It also helps you learn meal planning to eventually be able to buy the right amount of food on your own.

(It is easier to do if you have more people to feed though, like ideally at least one friend/partner/roommate to share the subscription with you. You can do a 2-3x a week meals for 2 subscription for one person, but it’s a bit much.)
