What are the applications of QM really?

>Applications
Pleb.
Science is about understanding the universe not making gadgets.
- Molecule models, explaining different "states", which let us compute reaction rates.
- Solid models of crystals/metals, letting us compute specific heat capacities, conductivity etc.
- Atom-photon models, theories of the [L]ight [A]mplification by [S]timulated [E]mission of [R]adiation
etc.

Plebs like you hold down humanity.

No sir, you are the pleb

That's not what I wrote, you jumped the gun there bucko.

Pretty much everything solid state
90% of chemistry
Particle accelerators
it's basically everywhere.

These have never worked right though. I've never seen as much distrust in any estimation method as I have in QM methods. It's literally regarded lower than dimensionless correlations with +-30% accuracy.

She looks like a young Dana Scully.
>OP: What are the applications?
>(You): Well, see we can use it to describe the theory behind this classical theory which is used to try and explain these applications.
>(You): Also we can use it to develop other theories.
Why are you (You) even replying when you don't know the answer?
proper Li-Fi
also magnet locks
>>7683440
they apply on you every fucking second
>>7683459
We currently fucking use it you condescending ignorant prick

Mental wanker

Making autists feel like they're geniuses
>>7685641
how is her condescending?
>>7683440
Well when we reduce transistors to nanoscale then particular problems arise. Thus we resort to QM to help solve these problems
Modern electronics rely on it.

As some people have already mentioned, there's a phenomenon called "barrier tunneling" that can be observed with electrons. In classical mechanics, when you have a potential energy barrier (let's think of a puck trying to crest over a hill of ice), it requires a specific amount of kenetic energy to actually get over that barrier, or it slides back down.
If it's an electron, however, and you have some kind of potential barrier, like air, it has a chance of just going through said barrier.
Most undergrad physics texts will give you a way to approximate the chance of this happening.
The thing is that this will only happen for something as small as an electron. Nothing as massive as, say, an electron, will actually do this.

O I c.
>>7686520
What distinguishes this from probability, or just guess work?
>>7686520
>as massive as, say, a proton*
No idea why I wrote "electron" there.
>>7687246
I'm not sure what you mean. Each electron has the same probability of tunneling, if that's what you're asking, so given a current and constant potential barrier, you'll measure a consistent current of electrons. STM machines use this.

>Science is about understanding the universe
Understanding in what way? Or do you mean it's about "finding" a more "accurate" "description" of how "the universe" "works".
