My school did similar shit, but good god I didn't think anyone would cancel a fucking test.

>My school did similar shit

What? I was a college freshman when Obama was elected president in 08 and we didn't do this shit.

>>8467540
Except Obama is a liberal so it did not hurt the little kiddies' feewings.

well thats fucken disturbing

someone tell me its a hoax plz

>>8470877
Well, fucked up as it is, at least sea ice melting doesn't raise sea levels. How's the land ice doing?

Also, link to the paper please.

50 billion to prototyping O'Neil cylinder style colonies

30 billion split 3 ways towards basic research in physics, chemistry, and biology, with an allocation committee made up of respected scientists in each field.

20 billion to be allocated equally between fighting climate change and researching ways to convince people it is a real threat that must be acted on.

Catgirl robot sex slaves. All of it

$100bn to autism research. I want to get cured before I turn 21.

how about you put a real candidate at the front of the Democratic party instead of a joke the caliber of Shitlary next time?

The multimillion companies behind her would probably have got their carbon footprints to shit countries should she had been elected anyway.

>>8472186
I wasn't even a democrat before the election and I registered to vote Sanders so Clinton would lose. Dems are dead to me and I no longer believe a political solution is coming ever.

Second part of your post isn't intelligible.

>>8472004
lol idk they probably just can't program. seems to me there's just a whole lot of autism going on around here

It's because CS is both interesting from a philosophical point of view and extremely useful and practical and often lucrative.

/sci/ only wants to talk about useless branches of abstract math and science that produce nonsensical or ambiguous results. [math]- \frac{1}{12}[/math], divide by zero, 0.999... etc.

>>8472004
I don't think it's comp sci itself, it's because ppl feel like comp sci turns people into shills, although comp sci has plenty of theoretically interesting stuff

>>8472121
no

Sounds to me like you just did

[math]
f(x) = \left\{\begin{matrix}
1, \: x\in (0,1) \\
0, \: x\notin (0,1) &
\end{matrix}\right.
[/math]

[eqn]\begin{array}{cccl} f: & \mathbf R & \longrightarrow & \mathbf R \\ & x & \longmapsto & \begin{cases} 1 \quad \text{if } 0 \,<\, x \,<\, 1 \\ 0 \quad \text{otherwise} \end{cases} \end{array}[/eqn]

Wrong, obviously

>to_what_import.bmp
you could at least give the definition. afair it's the integral rudin uses in his book

also from what I remember
>riemann integral
sum up rectangles under graph.
chop up domain (blue)

>lebesgue integral
same thing, but chop up codomain (red)

where does the riemann-stieltjes integral fit in between these two?

>>8470623
Well to give you a tl;dr of the definition:

You have two functions [math]f [/math] and [math] \alpha [/math] from [math] \mathbb{R} \supseteq D \to \mathbb{R} [/math], then the Riemann-Stieltjes integral is defined as

[eqn] \int_A f \mathrm{d} \alpha = \sum_{j = 0}^{n} f(t_j) (\alpha(x_{j+1}) - \alpha(x_j)) [/eqn]

With each [math] t_j \in [x_j, x_{j+1}] [/math]. This is under the condition that [math] \alpha [/math] is of "bounded variation", meaning:

[eqn] \sum_{j = 0}^{n} (\alpha(x_{j+1}) - \alpha(x_j))^{2} < \infty [/eqn]

Whenever [math] \mathrm{mesh} \mathcal{P} \to 0[/math], with [math] \mathcal{P} [/math] the partition of the interval.

This shit is useful, Reiman version is a special case (pretty much). The reason you have seen it in stochastic calculus is because with it you can more or less introduce Ito integration without talking about measure theory.

>>8470623
Do you not have google? Either way it is the RIeman integral if you only have countable many discontinuities (defined in the obvious fashion).
