back to your containment board, wasteman
Can someone demo how to find the sum to infinity of a series like this:
[eqn]1+ \frac{1} {x} + \frac{1} {x^2} + \frac{1} {x^3}+ \frac{1} {x^4}+... [/eqn]
?

You do see the dollar signs on the left of the poster, right? Last I checked Britain used the pound.
My father is in coma since 2013 because of an aneurysm. Should i begin to lose hope for him to wake up?
Sorry, but yes. The brain is not something to fuck with
>>7987481
No. Never lose hope.
>>7987481
maybe.
maybe you should, maybe you shouldn't.
How did you guys deal with realizing what all of you fags will do will not amount to anything significant in the real world? All your teenage dreams of being the Next Einstein and Feynman slowly being suffocated by reality. Falling for the STEM meme. The contradiction between your ambitions and the impossibility, what do? Pic somewhat related.
>>7987456
I don't know OP, but what caused your life to be such a piece of shit that you have a psychological need to try to make everyone else feel as horrible about their lives, as you so obviously do?
My teenage dream was to kill myself so I'd say I'm pretty happy

How would you improve math education?

Before university:
Someone post it.
After university:
Read textbooks. You're an adult for gods sake.

Don't pass an child who did not achieve a passing grade do to fear of social repercussions to the sudent. If a mixed age class rooms are required then just do it.

How difficult is it to learn trigonometry in a month? I'm considering a summer school course to do it as quickly as possible, but I'm not precisely a math whiz.
>>7986662
>How difficult is it to learn trigonometry in a month?
If you actually care and pay attention? Easy.
>>7986662
SOH CAH TOH
csc=1/sin
sec=1/cos
cot=cos/sin=csc*cos
tan=sin/cos=sin*sec
2π=360°
sin(0, 30, 45, 60, 90) = ½√(0, 1, 2, 3, 4)
cos(0, 30, 45, 60, 90) = ½√(4, 3, 2, 1, 0)
cos^2 + sin^2 = 1
There, you know all of trig.
>>7986662
How much trig?
Like just triangles, or all the way up to integration and Taylor series?
I would say that if you just want triangles, 1 week will be fine if you just put ~2-3 hrs a day.
For everything, 1 month of that study regimen will be sufficient.
Which circuit do you think is better?
>>7986462
second one because it's more compact

I'm pretty sure the first one doesn't even work desu
why dont we use railguns to launch radioactive waste barrels to the moon?
>>7986013
Why do that? Just make a waste disposible company, make the industrial plants pay you to take their waste, dilute it into the public water supply below the levels required by the FDA, and make municipalities pay you for the waste products?
it is win-win-win for you.
>>7986013
Railguns as they currently exist are not powerful enough to do that. Also there is really no issue with storing waste besides politicians and their constituents being dumb.
>>7986013
Because then you would make future moon geologists very angry. Just think, how are they gonna do those isotopic analysis on the moon to learn more about our place in the cosmos if the moon is polluted with radioactive garbage.
Reprocessing is the way to go.
Is it possible?

That's fucking gay.
Why do people spend time thinking these stupid hypothetical things up?
>>7985990
If your image is suggesting our memories. beliefs are false, then so are all our memories of thermodynamic experiments about entropy leading to your theory.
So the pic disproves itself

How can photons interact with matter so heavily even though they're point-like?
Light is an electromagnetic wave. It is not made of "point-like" objects.

Explain double slit experiment then, faggot. And by that I don't mean the one I performed on your sister last night.
If statements A and B are true, how do we know that statements A and B are both true?
Is all logic just made up?
>inb4 classical logic is axiomatic
How do we know that we can suppose things?
For example, let's say I have an axiom that says A is true. I then suppose that if A is true, then B is true. Logically, B should be true.
Why? Because you've never seen or heard of a situation where given the statements "A is true" and "if A is true, B is true" in which B was not true? That doesn't mean there couldn't ever be one.
Note that this is different from saying "if A implies B and B implies C, then A implies C." That is axiomatic.
What I'm saying is "given A is true, and A implies B is true, how do we know that B is true?" This is, as far as I know, not specified axiomatically.
tl;dr: How do we know that just because an axiom is true, any and all implications of said axiom are also true? This is not and cannot be an axiom in itself.
>>7985886
It's called a thought experiment.
Regardless of whether in actuality the premises of an argument are true or not, you assume they are true for the sake of entertaining the *validity*, not soundness, of said argument. Questioning otherwise is a whole separate (perhaps, metaphysical) exercise all together.
Hope this helps! (Unless you're just another semantic troll - in which case, fuck you.)
Daily reminder that you never really produce energy, you only steal it.

Did you just found out about PoCoE or something?
> steal it
you mispelled transform. Also energy doesn't belong to anything to begin with
Energy is never created nor destroyed we know this
what will the next big breakthrough in chemistry be?
MOFs
synthetic catalysts with enzyme-level specificity and reactivity
large scale production of nanomachinery
turning lead into gold
>>7985828
>he fell for the nanomachines meme
>>7985844
MOFs offer a pretty good way to organize molecular machines spatially. While we probably won't get metal gear solid 'nanomachines' we will get useful devices that have nanoscale moving parts.
I started the MOFs nanomachines meme here on /sci/. I am glad it is spreading.
