Hi,
sorry for asking but:
What should a person do ( like me for example) who is not very good in math but wants to work in a IT Job ?

/sci/, is it possible for the white race to be completely wiped out from the world through reproduction seeing as white babies can only be made by white babies? if so, how many years will that take? What would this cause?

Interesting question, OP

I'm trying to decide where I want to go to college. I want the best I can afford, but how do I tell whether a degree from one school is better then another? Besides the obvious that universities are better then community colleges, etc. I'm going into computer science. My top choices right now are Ohio State, and New Mexico Tech. Any help deciding?

Hello /sci/ i wonder if you can help me.

I'm not in school or anything so this is not homework. Anyways i have always been fascinated with the thought of atoms and such so i decided to educate myself a wee bit. I know its very basic chemistry but i'm a little confused.

1s2 2s2 2p6 3s2 3p6 3d5 4s1 is the electronic structure of Chromium. I know that usually the 4s orbital would get filled before the 3d orbitals but not in this case.

At this point '1s2 2s2 2p6 3s2 3p6' there a six electrons yet to find their homes.

My question is, has one of the electrons been taken from the 4s orbital and shared with the 3d orbitals, as to fill them up with one each?

I apologize if this is a stupid question.

So my little brother found a way to test divisibility by 11. Here is the semi-formal description of the basic rule:

<span class="math">11 \mid n \iff 11 \mid q + r[/spoiler] where q and r are the quotient and remainder of division of n by 100.

This rule can be applied repeatedly until a number that is obviously divisible by 11 is found. Experimentally, it seems to work out. 121 is divisible by 11 because 1 + 21 = 22 is divisble by 11. 10032 is divisible by 11 because 100 + 32 = 132 and 1 + 32 = 33.

So can anybody offer an explanation as to why this works? And if it doesn't work, can somebody point out where and why?
