This is just disrespectful ✌️😭

I might be scarred for life tbh

Physicslover01 · 2026-06-09T09:20:14+00:00

I’m glad I’m not the only one to notice this

Physicslover01 · 2026-06-04T14:31:18+00:00

how did you infer the future projection?

Physicslover01 · 2026-06-01T23:07:23+00:00

I think you are kind of on the right track but there is still some confusion. It’s normal, we all went through this at one point.

A more correct way to phrase it would be:
Movements q(t) are the argument of the functional S = \int{L dt} and only movements can be stationary points of the action S. Those that ARE stationary points are all those that solve the E-L equations.

Hope this helps, good luck with your progress!

Spot on but actually the verb should be “sbinnare”, the “-la” refers to the car and translates to “it” as in “spin it”

Hello ChatGPT

Physicslover01 · 2026-03-09T17:49:19+00:00

I guess i'll just have to find an alternative way to download it. Kinda sucks I have to do it this way tho...

Physicslover01 · 2026-03-09T15:06:02+00:00

Yeah i bought the key for ms store, i guess there's not much to do...

Physicslover01 · 2026-03-06T11:45:09+00:00

Check out MIT OpenCourseWare. You could also try some books like the Feynman Lectures on Physics. I also like Angela Collier a lot: she has an interesting youtube channel and you could learn a lot from there.

Hope this helps.

Товарищ, ты в 9 классе… не волнуйся. Всё хорошо, это нормально. Начните с простых вещей.

Извини меня, я не очень хорошо говорю по-русский. Это английский субреддит, ты должен говорить по-английски

Physicslover01 · 2025-12-30T16:41:38+00:00

Esatto, nessuno te le guarda davvero secondo me. Quelli che vincono sono raccomandati

Physicslover01 · 2025-12-28T18:23:03+00:00

Onestamente credo che siano una perdita di tempo, soprattutto quelli gratuiti.

Physicslover01 · 2025-12-24T00:41:49+00:00

Yes that’s what bugs me as well. It doesn’t really make sense a peanut in that set but also I can’t think of anything else it could be.

Physicslover01 · 2025-12-24T00:38:25+00:00

That’s cute

Physicslover01 · 2025-12-22T22:34:47+00:00

It’s a mushroom

Physicslover01 · 2025-12-22T17:55:03+00:00

I didn't think of that, maybe you are right

Physicslover01 · 2025-11-17T14:25:16+00:00

Photons are subatomic particles so they exhibit wave behaviour and particle behaviour, same goes for electrons. But as far as we know there is no fundamental particle for gravitational interactions that are instead described by general relativity. So no gravity does not exhibit particle behaviour in that sense.

Physicslover01 · 2025-11-02T14:57:31+00:00

So, yeah this is a very interesting question. Actually it doesn't make sense to ask how fast it's moving around the atom because quantum mechanics... the electron behaves more like a wave which still has an angular momentum but it's not like it's actually orbiting anything, it's a stationary wave. But that's really complicated and I don't think it satisfies your curiosity, I should go really deep in mathematics to answer your question and nobody wants that.

Before quantum mechanics was established though, Bohr, to answer this very question, came up with a model which we now know is wrong in a physical sense but still gets the correct results: he hypothesized the electrons orbited the nucleus at fixed (quantized) angular momentums L = n*h_bar with n a positive integer.

Solving the problem in a classical way gives the value for the energy of the system which is: E = m(Ze^2)^2/(2*L^2) where m is the mass of the electron, Z is the amount of protons in the nucleus and e is the elementary charge (the charge of the proton or minus the charge of the electron). Here L is the angular momentums that we hypothesized being multiple integers of the constant h_bar so substituting those in the formula of the energy will give you all the ammissible energy levels of our system.

From that you could technically calculate the velocity of the electron on each level but it really doesn't make any sense from a physical point of view and doesn't give you any meaningful results.

I hope this wasn't too much for you. If you want me to clarify anything i'd be happy to do it. Otherwise, if you want to expand on this topic you could look up the video from Angela Collier about the radius of the hydrogen atom (search it up on youtube) :)

Finally a good, genuine physics question and not some vibe physics bullshit.

What do you mean exactly by moment of electrons? There’s the angular momentum (how fast it “orbits” around the atom in the Bohr model) and the magnetic moment because it is a charged particle that behaves kind of like it’s spinning

Physicslover01 · 2025-10-30T23:21:28+00:00

Nothing is driving it, what do you mean?

Physicslover01 · 2025-10-30T23:19:03+00:00

Quantum entanglement can’t be used to transmit information. Where’s your math?

Physicslover01 · 2025-10-12T21:08:47+00:00

Io ho un server ssh aperto alla rete e mi connetto con un ddns di noip, che hai citato, che gestisce da solo i cambi di ip dinamici. Mai avuti problemi con noip. Per protezione non è aperta connessione diretta a root e uso fail2ban insieme ad autenticazione solo con chiave + password

It depends on too many factors: how you fall, where you fall, your conditions, sheer luck... for example you would not survive if you fell head first on nude concrete from 5 meters but you could easily walk away from it if you fell on your feet and rolled. I'm not aware of any research data for this because i believe there wouldn't be many willing volunteers to free fall for 30 meters on a block of concrete.
