If f(x) is a polynomial, then its derivative f'(x) is the coefficient of t in the expansion of f(x+t):
[math]f(x+t)=f(x) + t \cdot f'(x) + \dots[/math]

I want to program science stuff but I also like messing around with making cool OpenGL shit. I know python but it gets really slow as soon as you run anything a bit complex. What's the best language for my needs? C, Lisp, Matlab?

In the real world anything under 1000 lines of code Matlab, more than that C or FORTRAN.

that's because you suck at programming. you can try C and openGL but then you will just have even more complexity that you can fuck up. learn to program properly and then try again.

>>
>>8124264
would terraforming the moon be possible if we surrounded it with massive superconducting rings to make a magnetic field strong enough that we could sustain an atmosphere? I saw a paper about doing it for earth and they said something like the power from 12 nuclear power stations could easily produce a magnetic field something like 10% the strength of the earth's (i cant find the paper now but anyone else who has read it please correct me if im wrong) and it got me thinking about the moon.
>>
>>8124403
No. Gravity is way too low. Same with Mars though gravity isn't that far off to keep the atmosphere in place for an extended period.

>>8124198
Mathematical contests are more about how well you can apply trivial knowledge in convoluted ways - it has nothing to do with how good of a mathematician you are.
That said, you should definitely feel good if you do well in them, but if you don't do well, you shouldn't feel bad either because it says nothing about how good you are at maths.
I enjoyed the preliminaries to the IMO when I was a kid but I didn't have much time to prepare for it since I wasn't told that I was being entered.
I scored highly enough in the senior maths challenge (gold+) to qualify for the first round of the BMO, but with a day of practice I barely did half of the questions.
The small amount that I practiced was fun though, and it was my first 3 hour long maths anything.

Is it just my shitty UT campus or does every math department not tell you what text you need for the class until the first day of class?

How in the hell can I or should I study all this stuff. There's no logic in biology, to be honest, nothing. You just need to fucking memorise all this crap.

I'm good at math, and I will pass with perfect score, but I'm afraid I will fail to this shit and I will fuck my life.

Is there, at least 1 method how could help me to understand this "science".

nothing you can do, really. just memorize it and maybe make some pictures so you can deceive yourself into thinking you have an intuitive understanding of it
>>
No logic in biology? Bro, unless you're doing taxonomy that's complete bs

Everything revolves around food and reproduction.
Everything is mostly conserved with slight tweaks from molecules utilized for chemical reactions, genetic information and body parts.
Evolution is the change in the frequency of alleles (look up Hardy Weinberg).
DNA encodes RNA encodes Protein.

We know that the space is expanding because of the redshift of the galaxies but, how can we compare the color we are receiving with the color they really are concluding the redshift if we do not even know their colors? Or do we know them?

How do we know that the galaxies are "green apples"?

>>8124043
It's not that the colors are different from what they "really are" it's that we see the color changing (wavelength getting bigger) which must mean the galaxies are receding from us.

Spectral patterns.

Each element and molecule has it's own emission/absorption spectrum determined by it's electronic structure. The spectrum describes the frequencies of light that the atom/molecule can accept or emit, which depends on the differences in energy levels between electron orbitals, which critically depends on the composition of the atom/molecule.

Thus, spectral patterns act as a sort of fingerprint that scientists can use to determine chemical composition by just looking at light.

When redshift occurs, a spectral pattern appears shifted, but otherwise has the same shape. By matching up the "fingerprints" and seeing how much they shifted, we can determine redshift.

Make sense?

in MKultra style mind control what is the exact method of programming done on the brain to cause it to retain information?

I want to program a brain, however without splitting it into multiple personalities. Is trauma a required part of the programming or is it only necessary to split the subject into multiple personalities?

Repetition should be fine. If a person sees or hears the same mantra again and again over a period of weeks or even months, he will inevitably store it in his brain. This is a fundamental principle of propaganda. Just make sure the message isn't too long or too complicated. The shorter the memetic mantra, the easier it will spread.
