Hey /sci/
I'm looking to start learning math from ground up up until college level.
Anyone has any books they recommend? Preferably in order, I don't mind sitting hours on end studying.
Thanks a bunch.

So just hours of videos and interactive problems?
I'd prefer books and pdfs with clear explanations if that's possible because I don't have a Computer, but I do have quite a large pdf reader.

>>8525384
Wanting to do the same as you OP. I have been using Pauls's online notes and would recommend using those to you, but as for books i have no idea so also interested in seeing responses to this.

What is the difference between category theory, group theory, and set theory?
If they aren't fucking synonyms I'm going to beat up a math professor (I would have said shoot up a math class but I don't want the FBI breaking down my door. Now that I've said that let me say I plan to neither beat up a math professor nor shoot up a math class.) Because that shit is ridiculous.

category theory studies objects and arrows between them
group theory studies symmetries

They are completely different.
That being said your professor probably just wanted you to shut up and stop asking pedantic questions so he could teach the class and go home.

honesty it's pretty easy to send someone out of the solar system. The "problems" are.
Bringing them back.
Whats worth sending someone out there.

Do photons exist inside an electron, well, or in any fermion, lepton, that can emit, absorb this package of energy?

Yes; this is why electrons have lower energy levels as they get closer to the nucleus. Once the photons excape from the inside of the electrons, the electron loses mass, and therefrom momentum. Since it loses momentum, it also loses kinetic engergy, resulting in the n=1 energy level being the lowest. glad i could help
>>
>>8527341
oh wow, but about that loses mass, aren't photons massless, particles without mass, what do you mean by that when a photon leaves and electron, electron loses mass?
If 2+3×4=14 then how come 2+3×4÷2=8? Shouldn't it be 7?

Otherwise Zeno's arrow paradox cannot be solved. To reinstate quickly what the "paradox" is:
- An object traveling from A to B has to pass point C, which is 1/2way between A to B. This is of course experimentally observable
- An object traveling from C to B has to pass point D, which is 3/4 way between A to B and halfway between C to D. This is of course experimentally observable
- An object traveling from D to B has to pass point E, which is 7/8th way between A to B and halfway between D to B. This is of course experimentally observable
So on and so on.
The paradox is not solvable without the concept of limits where 1/infinity = 0. This is also the foundation in which Newtonian calculus is built on. Seems like a irrefutable empirical evidence for the concept of mathematical infinity

Nope. Godel's Incompleteness Theorem implies that the axiom of infinity is inconsistent.
>>
>>8524100
How would one solve Zeno's arrow paradox then? Without the concept of limits, the arrow would never reach B as it goes infinitely close to B in [(2^n)-1]/(2^n)

http://www.ibtimes.com/nuclear-fusion-germanys-wendelstein-7-x-stellarator-operating-expected-2456267
>Currently, the approach toward testing the viability of nuclear fusion involves using either a tokamak or a stellarator. A tokamak — one of which is currently being tested by researchers at the Massachusetts Institute of Technology’s Plasma Science and Fusion Center — is a doughnut-shaped device that can contain high-energy plasma using two-dimensional magnetic fields created by a ring of magnets. On the other hand, the stellarator — whose design is still largely untested — performs the same function using twisted, 3D magnetic fields.

I hate chemistry so fucking much. There no fucking logic on it, you're forced to memorise shit. Now memorise this crap, oh but wait there's a billion of exceptions you need to know. I hate even more than biology. Why the fuck my uni forces me to have chemistry in the first semester of my physics degree.
