And from your questions, you sound like a total astronomy newb. The site I linked is a great way to get your mind around the scale of our galaxy where the Pleiades live.

That one did, let's try again.

how do I become a ufologist?

Wow that's pretty epic.

Bitch, I have traversed the spiral arms of our magnificent galaxy on a beam of light, watching as it undulated and danced around the gravity wells of heavenly bodies. I have witnessed invisible curvatures in space so deep that they distort any mortal's conception of time and substance. I have been inside perpetually matter reactions so intense they don't let even subatomic particles form. I have straddled a plasma jet as it ejected from the centre of a mathematical singularity and provided a canvas for innumerable astronomical complexities to follow in its wake, including life. So.. no, no I haven't kissed a girl ;_;

Hello my dear friends,
I have a biggest favor to ask here. My girlfriend has to finish her chemistry assessment by Monday and she is not feeling well right now. I am no scientific person and I said to her I know smart people who might help you out! Guys, if you will help with this assessment, we will both be grateful to you!

At a high temperature, equal concentrations of 0.200 mol/L of H2(g) and I2(g) are initially present in a flask. The H2 and I2 react according to the balanced equation below.
H2(g) + I2(g) 2 HI(g)
When equilibrium is reached, the concentration of H2(g) has decreased to 0.046 mol/L. What is the equilibrium constant, Kc, for the reaction?
Answer 3.3
Possible answers:
11

Can someone please help me in understanding
d/dx(a^x) when
a^x = e^xln(a) so that d/dx(e^xln(a)) = a^x ln(a)

I know this is elementary stuff but this one thing seems very counter intuitive to me and I don't like moving on without fully understanding why this is so.

Basically I need a simple proof or a more descriptive explanation as to why this is so.

why does the galactic bulge of the milky way have a yellowish hue? seems to me it should be white with a blue hue, just like the spiral arms (because of the constant star formation). is it because of the higher mass concentration in the center which causes a larger redshift?

Well, Astronomy is the best way to get kids addicted to science.

Why is /sci/ one of the easiest boards to troll? Every time I come here you guys are arguing over more stupid bullshit. Is it because you all have something to prove? You want to seem smart to other people online? It's a goddamn anonymous imageboard, at most someone may remember a tripcode which anyone can change at anytime making them pointless in establishing a personality.

Proving yourself 'intelligent' on /sci/ is absurd, give it up and maybe we'll have better conversations without all the troll.

Government regulations allow for each glass of milk you drink to contain up to 1 eye dropper full of puss. Its been pasteurized but its still puss.

>inb4 homework thread

I decided to catch up a little on EM, and I have 2 questions. The damn book doesn't have any answers.

Suppose you have a surface S being intersected by field lines. And you have a projection <span class="math">S_n[\math] on a plane perpendicular to the field lines.

The number of field lines going through the surface S is equal to the number of lines going through the surface S_n? I answered yes

And the area of Sn = S*cos(alpha) where alpha is the angle between S and Sn.
