NASA bitches absolutely BTFO

Can someone post that picture of Elon smiling and Bezos crying? I need it for future shitposting

Fucking great

So does Tesla just repackage other people's stiff, slap a "Tesla" sticker on it and then charge through the nose for it?

>>8234369
equations are a type, you can write
E = x*y == 4;
then you can use solve, reduce and eliminate
you could have googled this in 5 minutes

>>8234379
Google brought me here

>>8234413
did you google "4chan sci"?

Gravity. The atmosphere has enough mass to be pulled towards earth.

>>8234062
gravity

>>8234071
Yeah, but then how are rockets, satellites, etc able to escape Earth's gravity? Of course they have added thrust but isn't the whole idea that gravity gradually diminishes the higher up, or the further into the atmosphere, you go? At the outer limits of the atmosphere there should be very little gravity holding it to the Earth. At some point, shouldn't the vacuum of space outweigh the effects of gravity on some portion of the outer atmosphere?

You should go up to the lecture hall, pull out a shotgun and kill yourself in front of your students.

>>8234054
Go back to /g/ this board is for scientists only

>>8234054
I learned python this year, for a class I took. Yeap, there are a lot of retarded things in it, but the libraries were really helpful.

Define entropy

>>8234009
The tendency of an orderly system to get in disorder.
(am i retarded?)

What if entropy is its own inverse?

You know you can graph it any way you want, right?

>>8233916
Yeah but this changes the method that it is using to get the value and doesn't even mention it.

To any moron it just looks like (and I've seen this been said before)
>It goes to infinity so far that it then comes back to negative infinity and then goes to -1/12

This is probably because Wolfram Alpha uses Mathematica internally which doesn't automatically generate conditions for sums.

Physics isn't mathematics

more like

2+2=17
4+2=19
10+2=27

>oh, hey, look, it's always off by 15, what if we redefine the formula to account for that and call it dark matter because we don't know what it is yet

Nothing. Enjoy your holidays.

>>8233909
Really? I mean guess okay. I figure if I study 2 hours a day every day I will do well enough.

>>8233907

Learn all about Fourier Series and Transforms BEFORE you get to phasors/Laplace Transforms
Study up on matrix algebra and solving system of equations with matrices
Be familiar with how to switch between complex numbers in polar and rectangle forms, e^ix=cos(x)+isin(x)

"no"

>>8233808
Why did you put it in quotes?

Because they want meaning, and science doesn't give it.
Humans will cling to anything, unless it interferes with something else of which they need to or want to understand its rational workings.

>>8233759
It can feel hard to accept there isn't some higher order to reality. People just tend to make connections and see patterns when coincidences happen. The lore of mysticism is intriguing, and becomes a matrix for those false connections.

Hmm, nice cringe inducing opinion, anyways you should do some studying.

SETI@Home is a botnet.
Anybody who runs it is a moron.
Literally giving government actors full access to your PC.
Then again any Intel CPU made after 2005 is literally botnet enabled with a hidden coprocesser that nobody is allowed to audit except American government agencies. (seriously look this up).
But yeah go ahead, it's not like you have any privacy left anyway.

>>8233701
you sound paranoid, all networked computers are accessible

>>8233747
It's not paranoia. It's literally facts. Look it up, or don't I don't care. You're just another good little goy installing botnets and NSA approved CPUs.

>>8233445
Because is much easier to use liquid water?

>>8233449
But the volume of water you have is the volume that is useable. The dry ice sublimates and covers a much larger area than the original block's volume making it several times more efficient than water in terms of transporting volume to effected area of fire. Also in California where there's a severe drought and constant wildfires it seems like this would be a better option.

SpaceX charges $6500 per pound of additional space they have available. These are usually booked months in advance and there's a long waiting list.

Our University has launched a Cubesat.

>>8233431
Well, how can I build my own? I don't want to wait possibly years to send something into a stable orbit.

>>8233434
>Well, how can I build my own?

You can't. Even if you had the money and an Phd in aerospace it would be really hard without NASA, Russian or help of other space agencies. This is because the metallurgy used in rockets is a closely guarded secret. It's why only a handful of nations have a space program.
