For the same reason that no one wants to have a surgery performed by "independent surgeon". Besides, AI lies a lot about physics. Something you would notice if you had formal training in physics :wink: But anyways, hi! PF is great for learning physics, and I hope that will be the path you'll...

And what does that mean?

How about doing your own reasearch beforehand? You ask questions that can be answered by just basic google search. But as I see in your posting history, you prefere to throw those questions here. And that's not how PF works, at least in principle, because of course there will always be someone...

Can you answer questions you've been asked?

It's OT, sorry,but: I'm 35 and exact same way xD I mean, I'll answer if I have to, but I hate it. Always did, because I was a very shy kid, now I'm not, but still it makes me stressed. But of course you are right about depression and loneliness.

Well, for me the question "Would you marry an AI?", asked randomly on the street or by phone, sounds stupid. I guess for a lot of young people from GenZ it does too. Stupid question, stupid answer. In the meantime, I used ChatGPT zero times. And I'm not willing to change that.

Why? Positively charged sphere is something way different than proton. Real world sphere would consist of milions of atoms itself!

Oh, ok. In Poland not that much, so I guess I didn't notice the context. They are not pedantic, they are sick and should not be close to any children.

You did not check how Lorentz force works, did you? It's a high school topic, so there are plenty of materials. Particles move on a helix on both poles. The difference between poles is the chirality of helix. EDIT: although I think that particles moving away from the star, move on helixes with...

Long time ago I read a set theory textbook where author said that Venn diagrams are way more general tools then most people think. He talked way more about that, but I was reading it just for fun, and it wasn't fun, so I don't remember more. Anyways, in polish schools they are taught just as a...

Why drawings are mentioned so much, when one can write equations without them? Some of you didn't have to make living out of teaching math/physics :wink:

Why exactly? Do you know how Lorentz force works? What does changing the sign of ##\vec{B}## do to particles movement? Hint: magnetic fields don't push particles the way electric fields do. Btw, this is high school level physics.

@Dale also has less than perfect vision, which he stated multiple times, and you seem to deliberately ignore it. EDIT: Oh sorry, I didn't see @Dale that you yourself wrote about it.

##Rcos\theta## is x component of vector ##\vec{r}## not ##d\vec{E}##, where by ##\vec{r}## i mean vector that starts at the origin, and points do ##dQ##.

Yes. Actually that was the way I was taught relativity at my uni. But it's less standard to do so and I guess more suitable for someone who's intersted in theoretical physics. Lecture notes are still online, but they are in polish: https://www.fuw.edu.pl/~wysmolek/Mechanika-2019-2020 "Wykład 2"...
