NASA isn´t a Spacial Organization to explore the lie "they" (the famous and rich 1% of people who runs this sad World) call "Universe", their ambition is to explore Antartic, the forgotten Continet, since they find out about "what" really is behind that intimidating ice/snow wall´s. We can think/imagine about so many possible and credible reasons for this constant lies and corrupt educational system, for exemple:
-> one reason we can´t even imagine, behind that ice walls in Antartic is a military resistance for this fake sociaty (like MATRIX);...

Hey. If you want to be fucking retarded, you are in the wrong place.
why you calling me retarded? I´m only want to know some opinion´s.....
All matter is composed of waves. Particles don't actually exist outside of the mathematical model. Photons, Electrons, Bosons etc do not exist as individual ball-like particles, and are a mathematical quantification of a wave-like phenomena.
Am I correct?
Discuss...
Also, with Einsteins' wave theories on gravity due to be confirmed, can we finally stop looking for the "Graviton" etc and switch to Quantum Field Theory?
OP here, I just saw this thread..
>>7843901
.. And I have to say I'm disappointed with the level of discussion. Is /sci/ a serious discussion board? I assumed it was.
>>7845948
The general gist is that things are not intuitive. You are trying to map something that happens at a completely different scale to something you can relate to like a wave.
The reason waves to you behave a certain way is because of lots of observation and matching waves to a certain pattern.
When you talk about things at a very small scale they don't behave along the same patterns as at bigger scales. So you can't match their actions to any known pattern you can think of.
Your entire...

Why cannot divide by zero? Tell me /Sci/ mathematical dumbos.
>>7845901
You can't divide by real numbers since they don't actually exist
>>7845901
Back to >>>/r/eddit
consider the function 1/x for any real x. as you get really close to 0 from either side, the output of the function gets bigger and bigger.
what should the output be when x = 0? it must be bigger than all the other outputs, which cover all real numbers. so the function must be infinite there. But infinity is not a real number, so 1/0 is undefined.
Friendly reminder that e^(i*pi) + 1 = 0
>>7845900
THANKS REDDIT
Was euler a redditor?
So (e^i*pi)/0=1.

Applied math, duh.

>>7845887
In my experience it is usually someone from a religious background trying to replace man god with math god
Discussing whether math "exists" or not involves so many ambiguous concepts that it doesn't drive us anywhere because there is literally nothing to know about semantics (they're defined by us), so OP is as much a faggot as the people he's criticizing.

How much math did you have to take to get your CS degree?
How much did you take as electives?
I took quite a few elective courses such as real analysis, abstract algebra and stochastic processes.
Are differential equations useful for CS? Obviously, they are used for simulations, but beyond that?
>>7845852
Diff eqs are also used in signal processing.
>>7845852
signals and circuits both use diffy qs
>wasting billions of dollars on rockets when there are still millions of starving children in the world
Explain yourself spacefags
They should learn how to fucking feed themselves.
They should learn how to build a waste system.
They should stop being so fucking stupid and clinging to retarded beliefs that only make their lives worse.
They should start a real fucking government and actually make it work. Not just have some Jumba Mumba who is the leader for a year and forces everyone to carry him around the place he leads on their shoulders while he praises some false god.
Yes I am mad, all of the stupid fucking idiots who demand help from first-world countries need to get off...

Well, it isn't even this >>7845672 you see they did feed them selves at one time. However, the USA sent them food for a generation or two then removed that food. During that time, farmers stopped farming because they couldn't compete with the free food. By the 2nd generation no one who was physically able to farm knew how to farm properly. The food was cut off from the USA and everything turned to shit.
This is a common method the USA uses to completely...

Because traveling through space will actually enable us to visit new worlds, rich of resources and we also escape the threat of being wiped out by a meteor one day.
And because starving is only the problem of starving people by the way.
Is there a formula to calculate the grey area shown in the picture?
I was thinking about subtracting from the area of the bigger triangle [math]A_T = \frac{r (r\tan x)}{2} = r^2 \frac{\tan x}{2}[/math] the area of the circular sector [math]A_c = r^2 \frac{\pi x}{2\pi}[/math] and the area of the smaller triangle outside the circle [math]A_t = \frac{a b }{2} = \frac{(r - r\cos x) (r\tan x - r\sin x)}{2} = r^2\frac{(1 - \cos x) (\tan x - \sin x)}{2}[/math].
So we get [math]A = A_T - A_c - A_t = r^2 \frac{\tan x}{2} - r^2 \frac{\pi x}{2\pi} - r^2\frac{(1 - \cos x) (\tan x...

Your writing is incomprehensible but I'm assuming you are asking you to do this without integrating?
>>7845619
Yeah I need to calculate the grey area but I don't even know if it has a name, on google I couldn't find anything.
That's an attempt I made but I don't know if that's right.
I'll repost the text using the eqn tag, maybe it will be easier to read:
I was thinking about subtracting from the area of the bigger triangle [eqn]A_T = \frac{r (r\tan x)}{2} = r^2 \frac{\tan x}{2}[/eqn] the area of the circular sector [eqn]A_c = r^2 \frac{\pi x}{2\pi}[/eqn] and the area of the smaller...

specifically, how does it avoid destructive pre-ignition detonation?

/co/ couldn't figure it out. Let's give sci a try.
Two men of equal intelligence attempt to outwit each other. One can see the future and one can read minds. Who outsmarts the other?
>>7845474
No one wins, because one cannot win without the other
>>7845475
If one of them knows the answer, then it depends on who shouts first
>>7845474
Assuming only one of them know the answer, then it is the future reading guy, he can see the answer immediately, while the mind reader has to go through the other guy's thought process which takes time
I really don't like how the multiverse theory has just become a meme for fedora tipping plebs
What are some good arguments that dismiss the muliverse? It's almost like becoming the next flat earth/hollow earth expansion pack for next wave of bandwagoning trolls

Scientists are now fedora tipping plebs. Thanks /sci/
If you believe in Schrödinger's Cat, then there's multiple universes existing simultaneously for all quantum events. You can say that when we observe anything, the other universes don't exist, or maybe they do.
Or you can say that there were other big bangs in higher dimensions. The big bang was possibly just a quantum fluctuation.
>>7845464
>What are some good arguments that dismiss the muliverse?
They are about the same that dismiss the existence of god : there is absolutely no evidence.
What are some good introductory and intermediate texts on non-standard analysis?
any physics text that uses infinitesimals :^)

Am I blind?

What drugs should I take if I want to be completely emotionless and apathetic?
>>7845334
try heroin. I hear it works great for the apathetic side of thing
>IV or bust!
Alcohol, xanax etc anxiolytics
why would you want to be apathetic? you lose motivation to do anything or to interact with anyone
your best chocie for that is anti-psychotics like seroquel. they're well known for zombifying people as a side effect
Can somebody explain the difference between the 3 Ways of measuring Temperature? Celsius, Fahrenheit, Kelvin.
Oh, and do explain thoroughly
>>7845333
your pic sucks
Thats the best I could find tho
>>7845333
Celsius and Kelvin are the same scale, Celsius is just more appropriate to humans.
Fahrenheit is american and I'm not quite sure the significance, plus that picture is fucking retarded and doesn't make any sense
