I would read a few seeing as you don't have references in front of you.

Guys, I think I just managed to create carbon in a metallic state. Where do I go from here?

Quick math question sci.

One of the fundamental theorems of integrals is that S(b top, a bottom) f(x) = - S(a top, b bottom) f(x)

Why exactly is this? I understand why all area underneath the X axis is negative, but I don't understand why flipping the way you "read" it will change the sign.

Also, in integrals, do you always do the top number of the S first, then the bottom, or raither, do you always "read" from the greater value to the lesser, and do it in that ordeR?

Sorry if I'm not clear, my math teacher doesn't really explain things at all, we just do it. Let me know if I need to clarify anything

Looks like she used to be kinda cute, but she's hambeasted out with age. The years aren't kind to this one at all. At any rate, why the fuck these threads again guys? She's has the dumb, bad.

Laugh at her shit replies (EK = level of average layman), sage, and move along.

the underage b& is strong in this one

protip: shut the fuck up, kid. You don't have strong leadership qualities, or a vast intellect. You are 15. You have shown the world nothing. Humble yourself. That's step one.

I went for the biology shit course cause I'm going to med school and there are LITERALLY no guys in these classes, only girls. I was joined by one male friend of mine, that's it.. and guess fucking what; THEY ARE FUCKING BORING, GIRLS HAVE NO SENSE OF HUMOR AND CHATTING WITH THEM IS LIKE TALKING TO A DOG, THEY ALL REACT THE SAME WAY AND HAVE THE SAME CRAPPY HUMOR LAUGH AT THE SAME FUCKING FUCKKKKKKK
KKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKDIEIIII

yes, imad. I always go eat lunch with my buddies in the physics course. now there we can raise some hell and have fun.

But yeah, some of those chicks are hot and all that. That doesn't mean chatting with them is any fun. fucking retards.
