Does it get affected? if you're in the presence of a strong electrostatic field, or a strong magnetic field, will it affect the ability of an EM signal to reach you?
>>
>>16829338
electrostatic how?
metals put up quite a large electrostatic field in a sense and will reflect em radiation
solar radiation is heavily reflected by the earth's magnetic field so yes as well
>>
>>16829338
I'm pretty sure waves can superimpose over it, since the EM field is linear. However stuff like power lines can generate radio waves which interfere with other radio waves

The field itself will not affect it, unless it's in a special material, or it's strong enough to cause significant photon-photon scattering.

taking both the /sci/ and /x/ pills is the only rational choice. any intelligent anon will realize you need both to even attempt to understand the full picture. of course you will find a ton of bullshit in both and have to sift through the crap, thats the hard part.

how many hours a day do you have to study to do well in medical school?

Its just important to have the right parents, the right friends etc, for example if both your parents are doctors , that shit will be pretty easy, unless youre born handicapped or something. However if your parents are *crying noises* that will just be a pipedream

Not saying there arent exceptions to the rule

Man, German schools really are fucking terrible. Your university is so obsessed with appearing "advanced" that they have convinced you that you've been taught material you know absolutely nothing about. One look at Amann & Escher is everything you need to know about how shit German real analysis education is. So obsessed with a cargo cult notion of "rigor" that your students don't actually learn anything about real analysis by the end of it. They'd literally have been better off doing an American undergrad course because then they'd at least understand the material they were taught instead of getting this veneer of "rigorous mathematics" that's a micron thick.

[math] S \in \text{Ker}(f) [/math] makes no sense. If you meant to say S = Ker(f), then it should be pretty clear what your answer is. Are V and W groups? Is f a group homomorphism?

If you meant to say [math] S \subseteq \text{Ker}(f) [/math], then you can't really apply the theorem since the map f' (used in the theorem proof) taking V/S to W via f'(aS) = f(a) isn't be one-to-one unless S = Ker(f). Intuitively, that wouldn't even sound right; if V/Ker(f) is isomorphic to f(V), it wouldn't sound right to be able to mod V out smaller and still be isomorphic to both f(V) and V/Ker(f)

I think everybody in this board knows math is pretty awesome. So, I thought I would dedicate the many hours of free time I have to learning math through textbooks.

This is my current reading list:

- AoPS Introduction to Algebra
- AoPS Introduction to Geometry
- AoPS Intermediate Algebra
- AoPS Precalculus
- AoPS Calculus
- Spivak – Calculus
- Axler – Linear Algebra Done Right
- Hubbard & Hubbard – Vector Calculus, Linear Algebra, and Differential Forms
- Arnold – Ordinary Differential Equations
- Bertsekas & Tsitsiklis – Introduction to Probability
- Wasserman – All of Statistics

Is this good enough until I want to move into something specific?

Decent advice actually. I learned far more when I attempt a project and get a roadmap from an AI than just trying to work through a textbook. Having an end goal does wonders for motivation.

>>16830749
Not that guy, but I agree with him. Mainly because I think it’s a bit too basic. It doesn’t prepare you for a real calculus book like Spivak. I know, I know. You guys can go straight to Spivak. I personally couldn’t. Something like AOPS is a better preparation.

that's exactly the point and why imo is good for a rapid refresh or perparatory to "get into math"

I thought modern physics was strange, but then I decided to learn a bit about what mathematicians are doing nowadays and I am completely baffled. I have a pretty good understanding up to vector calculus and linear algebra, but this stuff is beyond so many layers of abstraction it might as well be gibberish to me.

Why? I don't ask how mass bends space-time by the way. I ask why mass bends space-time, so another mass follows that 'curved' path.

The satellites in high earth orbit will last a very long time in orbit, while those in low earth orbit have shorter lifespans, and sometimes have propulsion to boost themselves. And satellites do fall out of orbit from time to time. Anyways that's it from me, you are retarded

Is this "bending" simply a model of how they explain the properties near a gravity well but space-time is not actually bent?
>General Relativity - mass bends light
>Quantum physics - uh we can't explain gravity
>String theory - Gravity is a string just like all the other "particles"

If it's being bent, wouldn't that imply an extra direction where it's being bent?

I think I'm with the string theory folks in that gravity is a force just like all the other forces. It's just there and we have to explain it somehow by quantizing it or some other method.
>>
>>16831133
Space isn't bent - the relationship between time and space in the presence of matter-energy becomes nonlinear, and as a consequence, inertial paths for objects become curved instead of straight.
>>
>>16828225
gravity is probably a dimension not a force. time is maybe a force not a dimension. once you think of it this way it's somewhat easier

I have schizophrenic thought about air rails for biorobots. What do you think — should we, in the near future, expect zones or grades separated by allocated frequencies for medical devices? As biochip technology advances, is it possible that people could enjoy a better quality of life in areas with higher-quality allocated frequency zones than in higher economic class ones? Something such as Ghetto in old nazis style..

0 is also its own opposite, 0 = -0, because it is an incoherent definition that leads to a numerical deductive explosion of logic, all statements of truth made by arithmetic are trivial truths among infinite truths because the original number is a self negating logical contradiction that inevitably imbues self contradiction upon all values since x = x*1 = sqrt(x*x)*sqrt(1*1) = x*sqrt(-1*-1) = x*sqrt(-1)*sqrt(-1) = x*i*i = x*i^2 = -x.
