You do realize that is a very valid fictitious force in regards to non-inertial frames of reference, right? You have taken even a basic classical mechanics class, right? You are not just some freshman/high school Gen ed student who just learned about rotating bodies, right? Come on.

I've noticed that when I do this the light shifts to blue.
Blue fire is hotter than red fire, so is the light just getting hotter due to friction?

How did they get away with this?

Do you know anything about this kind of physics? Just asking

What I'd like to know is how they got away with basing quantum physics on probability, rather than just trying harder to figure out a measuring method that doesn't influence the result.

>trying harder to figure out a measuring method that doesn't influence the result.
If you want to try and figure that out go ahead. But according to current physics theories there is a hard fundamental limit on how much uncertainty exists in your measurement.

I want to be smart, /sci/. I'm interested in quantum mechanics, astronomy and computer science. Can you recommend me some books of these fields? I feel like I'm not getting any smarter by watching youtube videos about, it seems like just the "for dumbs" version.

First you need to learn some math. You don't learn quantum mechanics through pop sci metaphors, you learn it by making sense of the math.
>>
>>8724977
Well, that's a beginning. I only know the high school math, is this enough?
>>
All of those books are useless unless your algebra and trig skills are good. In order to understand CS books you need a solid foundation in combinatorics, go read Rosen's textbook. CS really has the lowest "knowledge" entry point, but it can get much more complicated once you pass that threshold.

Help me understand how does electricity travels inside a wire.

They teach us in school that there is electrical current when there is a difference in potential so the charge carriers travel from higher potential to lower to balance itself out and we use this desire for balance to power up stuff. Somewhat similar analogy with gravitational potential energy.

But I dont understand how do we make points of high potential in the first place?
I thought that electrons do not move that much in a wire, they are just a medium for the electrical force, just like air is for the sound.

So how do we make electrons that also repel each other be in the same place so when we let them go they discharge toward low potential point and thus invoking the current? I mean if they actually never move much that means there is not excess of electrons in one place right? Its the excess of the "electricity"? I dont get it sorry

Electrons don't actually move, they are energized so the matter itself becomes energized in a way that creates imbalance. Magnets.
>>
>>8724915
yeah, magnets. look up Faraday's work, its pretty easy stuff.
>>
They don't move that much, but they are very tightly compacted and push against one another.

google for the complicated explanation. for treatment, just log off and suffer until you get bored enough to deal with whatever your real problem is. good luck.
