Why is it so hard for black people to annunciate?

I have never met one that doesn't speak like a stereotype. I've only seen a couple british blacks on tv that speak clearly and without ebonics.

I am not a racist, but I'm also not very well versed in biology or physiology. Is there a fundamental physical difference that causes this?

It's the same reason why british people speak like retards, or why frogs speak like frogs. People that you interact with in early stages of your life speak with a determined accent, and you pick it while learning how to speak.

you are wrong.
x+y=0

this overdeterminate system has an infinite number of solutions.

>>7806687
It's not overderminate since the equations are linear dependent.

No, he was a white knight cuck like pic related. He could have been from lib arts or business, as it usually is.

Never pick up a woman who was a slut, because she will forever be a slut. You may fuck her one or more times. You can use her for all I care. Actually, even have her as your gf if that will secure easy sex.

BUT NEVER EVER EVER AND I MEAN EVER MARRY AN EX-SLUT.

Hi, can someone here help me with some python?

I am trying to generate a list of random length (but between 3-15; in following example), containing random integers (between 1-10 in following example).

At first I tried using the random.sample function:
>a=random.sample(range(1,10) , random.randrange(3,15))
But then learnt that it picks unique elements from the given population - hence the length of my first argument must be greater than the value of my second argument.

What other methods are there that I can generate a list to suit my requirements?
I want to try keeping it compact and only one line of code too please.

>>
>>7810261
You could try numpy
def ran_list():
return np.random.randint(3,16,random.randint(1,10))
>>
>>7810263
thank you. that fixed it for me.

i slightly modified it and am now using:
>testlist=[random.randrange(0,100) for i in range(random.randrange(2,20))]

(ignore the different number ranges i selected).

thanks, bye!

Ok so Man of Steel kind of sucked but it does make me wonder

will people ever evolve to the point where we are no longer creatures who reproduce sexually? I mean, think of how convenient it would be if we could just facilitate the whole process through futuristic technology, and no longer have to spend so much time bending to the will of your primitive instincts which beg you to begin a relationship and have sex and all that stuff. It takes up so much of our lives.

Of course we will. One day in the future babies will be made in artificial wombs, allowing women to be more productive and less exposed.

More genetic extremes will be women born without a womb or any of that bullshit that make them bleed each month.
The most crazy would be removing the men's balls, removing the sperm and all the mess that brings.

Sex can continue for fun and socializing but all the hassle of nature will be removed.

Ein paar deutsche Anons hier die mir bei diesem Rätsel helfen können?
(Bild relatiert auch)
Es ist eine verschlüsselte Matrix. Der Schlüssel ist
A=5 -3
. -3 2

Es muss von links kodiert werden
245 215 285 515 275 345
378 348 448 818 428 558

(Die Zahlen und der Schlüssel stehen so übereinander wie hier nur halt in einer klammer wie bei einer Bruchrechnung)

Wenn die Matrix decodiert ist setze für a=11, b=21, c31usw bis y=251, z=261

I bet you are one of those spergs who think that geniuses are just autists who didn't even have to work all that hard, they just naturally knew everything.

Yeah yeah, fuck off.

If you're a strong fundamental reasoner/algorithmic intelligence then yes there's a way for you to learn at a more rapid pace provided a specific kind of post-singularity information that only people like us can generate. If someone comes to you asking for solutions to NP-hard or NP-complete problems, tell them to kindly fuck off and solve negotiation theory in their own timeline and stop concealing their temporally parasitic aspect using time travel.

NP stands for non-polynomial. There's a thread on this board right now where you can see a shill soliciting for methods to solve NP-hard problems. He's careful not to use the term NP-hard despite how common the category is for reasons that you can figure out on your own if you come from a post-singularity region of time. Make sure you have a good grasp on problem complexity theory before you let anyone use your brain for their as of yet unconveyed purposes.

Well, I'm studying engineering, but I found that the engineering method for learning calculus (rote memorization) is shitty as fuck.

Learn things "the hard way". In this case, learn calculus as a math major would, read and understand the proofs, and then things will stop being a clusterfuck of stamp-collecting and will turn into simple logic.

any introductory material science textbook. hopefully you took general chemistry.

Majority of engineers take a fairly large course that serves as an introduction to Materials Sciences.

My book for that class was called "Materials Sciences and Engineering: An Introduction".

http://www.amazon.ca/Materials-Science-Engineering-An-Introduction/dp/0470419970

There are a billion similar books out there. They all cover roughly the same material.

You'll struggle to understand without a decent grasp on first-year engineering concepts (think, basic Chemistry and Mechanics)

hi /sci/ i have to study for a test tommorow about residue theorem. Id like to have some exemples .
Can you pls solve me these exercises .

>>7810206
The first one is trivial. The next two are also pretty easy.

You suck op.
>>
If you want to study, imo, do lots of problems. The more you do, the more you get a feel of what to look for on each one.

Some general ones:
1. Draw the region described.
2. Find the number of poles, if any, and the order of each.
3. Compare them to the given region. Which ones lie in it? Which ones don't?
4. Then just apply Cauchy Residue Theorem.

Anything else, and it gets problem-specific.

I hope this helps a little.
>>
>>7810206

Those are pretty easy OP, just use the cauchy integral formula

https://en.wikipedia.org/wiki/Cauchy%27s_integral_formula

Has anyone read this book?
is it pseudo-science or a good critic of materialism?
can you also recommend more literature which criticizes materialism?

About negative temperature:

I understand how you can get it in a system and so on, but why does it not break the second law of thermodynamics, as entropy is decreasing in the system? Obviously I did not fully understand the second law, but what is the explanation?

>>7810143
It's a sliding scale thing; the universe's most cold temperature is absolute zero. In worlds that allow for non-entropic energy system, cold magic can dip down into the negative millions. It's often a very good way to put a permanent end to something.
