Are those β angles meant to b equal? Because that's a shitty diagram nigga

We do not yet know the answer to "how do observations or memories affect neuron structure".

Birch Swinnerton-Dyer conjecture is essentially the bridge between the analytic theory and the algebro-geometric theory of elliptic curves. It's been extremely useful for predicting behaviour in these areas of study, yielding results that would have been otherwise difficult to suggest.

The Riemann hypothesis is the key to understanding the behaviour of primes but as far as I know the more interesting question is the generalized Riemann hypothesis, which gives well, more information about how primes behave.

Essentially anyone working in number theory takes the above two for granted when doing research.

The Hodge conjecture would probably take a semester to explain depending on background

Yang-Mills is the one they threw in so the physicists could be happy

P=NP same deal but for CS majors

Navier-Stokes was put in for the feminists since physics is sexist for being rigid and not fluid enough

I like how this post starts really well and gradually descends to shitposting

>>8091582
It starts as imma shitpost but do so subtly and respectfully, then descends into idk what i'm talking about but i'll shitpost anyway.

Which is the level of quality that we should all strive for.

Its technical and engineering data that is kept secret. The science is available to everyone

>>8091222
because engineering something is harder than sciencing it.

>>8091222
We know about the designs that were used, not about the process to manufacture a core.

Try to invent shit to become rich with internet guides
->80% nothing happens/you get bored and hungry cause no job
->10% something explodes cause no work guidelines
->10% you make something useful, a giant corp notices and they buy you off cause you need money to eat something

Such hard is life

I have Bresser 70/900. Cool telescope, but it comes with some god awful eyepieces. I'm planing on buying gso or synta 10" dob.
PS: anyone know what mount is it?

What is the best cheap refractor telescope for someone that's never owned a telescope?

Wait, does this g-diffuser negate the effect of outside gravity on all objects within the effected area. Or does it negate all gravity in the effected area including gravity caused by objects within the area?

OP here, I mean Newton's First Law.

I was just baiting.

>>8090685
Outside gravity working against the localizied area.

no

Teaching to a bunch of idiots who fucking hate school and teachers and are only there because they are forced to sounds like hell. Nobody respects high school teachers, I sure didn't when I was a teenager brat.

>>8090133
Depends on the school.

I would love to be an AP science and math teacher at a top private school where the average SAT score is above 2000.

I would hate having to teach remedial arithmetic to inner city niglets.

I never understood the hate directed towards evolution (at least scientifically), especially considering films like The Core, 2012, and iOrigins exist. I understand that a certain amount of will suspension needs to take place, but both of those were obnoxioulsly bad. I suppose it's the same with Lucy, everyone jumped on the "hurr using 10% of ur brain is myth", as if science fiction was meant to be an accurate reflection of reality.

>>8090150
2012 is infinitely more believable that Evolution

Just reached the bit where the idiot sings in the shopping mall an supports the dragon

nice bait

Try approaching from the other side of 0 and you'll get -infinity. Also try taking calc 1, that should clear this up.

>>8089770
When the numerator becomes small and approaches zero and the denominator does the same, the division can be anything, depending on how fast the numerator goes to zero relative to the denominator. It could be 0 or 7 or infinity or not converge.

Isn't an equalizer already the special case of a pullback when the two arrows have the same source?

On that note, I have a somewhat stupid question (probably too obscure for /sqt/ though):
According to
https://qchu.wordpress.com/2012/09/29/monomorphisms-and-epimorphisms/
the natural map (m: d --> e in OP's example) is stated to always be a monomorphism, meaning that the pullback is a subobject of the product. Intuitively I can see why, but I can't seem to formally prove it from the definition of monomorphism.
In fact by using uniqeness of the universal map I get that mx = my for any two x,y. What am I doing wrong?

>>8091282
d is not the product here


this is what I know:
when 1 exists,
-the product of 2 objects is the pullback of their unique arrow towards 1
-given two arrows f, g, with same domain, codomain, the equalizer [f, 1_f] and [g, 1_f=1_g] is the pullback of f by g


-if the pullback of two arrows f, g exists, then if f is monic, then g*(f) is monic
this is false when you replace monic by epic

the kernel pair of an arrow f is the pullback of f by itself
-if the kernel pair of f exists, then the projection arrows are epic

f is monic
iff
-its kernel pair exists and it is (dom f, 1_f, 1_f)
iff
its kernel pair exists and the projections are equal

I don't know about stats, but I majored in math and my undergrad advisor literally told me I wasn't good enough to go a good grad school. I had all A's and B's (except for a bio class) and did a decent course load including grad level classes in measure theory and algebraic topology.

>>8087366
god damnit

>>8087359
Why would any grad school want to accept you? Have you done anything encouraging aside from grades? I don't know what you expected to happen.
