Why specifically cant QM handle 2 electrons?
Ie what about the schrodinger equation breaks down once the second electrons are added?
Why can't some term just be added to the hamiltonian to account for the second electron?

because according to QM, all electrons are completely interchangeable. Therefore, having "two electrons" is logically incoherent within this framework, since all electrons are the same.
>>
>>8494671
so what do they mean when they say the SE cant be solved for 2 electron systems?
i always took it to mean it was too complex, but i guess it implies a more fundamental reason
>>
>>8494673
It's not even a well-posed question, because QM doesn't allow for the existence of two separate electrons
If conservation of energy is true, then why don't I lose weight when I exercise?

Ford Fulkerson is at the very least applied mathematics. It definitely is taught to CS majors, and graduate students use this text for a course on combinatorial optimization at my uni.

Why do cats hiss when the're scared, yawn when they are bored, scream when they get angry, meow when worry, but they don't ever laugh or manifest the things they find funny with a sound?
Do they just not find things funny ?

Cats are natural born autists, I don't think they have a sense of humour.
>>
>>8491977
The emotional spectrum of cats goes from "not annoyed" to "very annoyed" and that's it.

>>8491977
Humans also laugh when they are nervous.

what are you asking?
>>
>>8490326
Had a concussion once with lesions in the frontal lobe. Symptoms:
>Almost complete loss of long-term memory
>Agitation, restlessness
>Sleeplessness, only few hours of dreamless sleep every night
>No way to focus on anything for longer than a few seconds
>Very limited speech (only "Yes" and "No" responses etc)
>Personality changes
>Eventually depression
None of that was permanent. It took about a year to fully recover. No effect on intelligence was observed.

what do you mean loss in long term memory?

Do you guys think its possible to catch up with algebra, geometry, trigonometry and calculus in less than 2-3 months? I plan to start college in February 2017. I would like to know your opinion about learning these in less than 2-3 months. I have basic knowledge of precalc, I finished high school in 2008, but since then i had 0 practice in maths, now I plan to retake college in 2017, to major in mechatronics.

They are all extremely easy, yes.

>>8490573
yo fuck off
OP, depends entirely on you, the effort you put in, & how practiced you are at learning. if you're used to problem solving & diligently attempting to wrap your brain around new concepts, well that'll help
>>
It's definitely possible. Just read a section or two each day and end your day with multiple practice problems. The more problems you try (and sometimes fail at) the more you'll understand the concepts.

Outsourcing is yesterday's big thing. Today smarter robots and 3D printing means outsourcing is less needed. Insourcing means your own workers now can afford to buy what you make, that is what Ford counted on.

So I'm trying to prove that the light cone [math] \eta _{ \mu \nu } dx ^{ \mu } dx ^{ \nu } = 0 [/math] is invariant under a couple of transformations. The way I'm thinking of doing this is to act on the metric with a couple of Jacobians, so given a discrete transformation [math] x _{ \mu } \to x _{ \mu } / x^2 [/math] I'd have: [eqn] \eta _{ \mu \nu } \Lambda ^{ \mu } _{ \rho } \Lambda ^{ \nu } _{ \sigma } dx ^{ \rho } dx ^{ \sigma } \\ \text { Where } ~ \Lambda ^{ \mu } _{ \rho } = \frac { \delta ^{ \mu } _{ \rho } } { x^2 } - 2 \frac { x ^{ \mu } x _{ \nu } } { x^4 } [/eqn] So after some algebra [eqn] \eta _{ \mu \nu } \Lambda ^{ \mu } _{ \rho } \Lambda ^{ \nu } _{ \sigma } dx ^{ \rho } dx ^{ \sigma } = \frac { \eta _{ \rho \sigma } } { x^2 } dx ^{ \rho } dx ^{ \sigma } =0 [/eqn] Is that it? Does that imply that the interval is invariant? And if it does, is that a general method for solving these types of problems? I'm sure I've done this before in the past but that would have been some years ago.
