Energy demands are too large for just solar and wind at the moment. Nuclear works nicely to supplement those until they become more efficient but nuclear has its own issues. Nuclear is still infinitely better than any type of fossil fuel so don't worry about the issues with adding more nuclear plants until we completely eliminate fossil fuel production.

OP here. I've heard arguments that they're really fucking expensive, but I've also heard argument that they're cheap as shit. What are they?

Like, are they just cheap once you get standardized reactors and economy of scale or?
Also, why the fuck is no one using IFR style breeder reactors? Whats with all the LWR, aren't those wasteful as heck?

(pls help, I'm not scientifically bright, but I've been trying to learn).

>>8491316
like what??? the first derivative of [math] x^{2}[/math]? the pythagorean theorem?

get a life moron or youre gonna end up dieing alone.

I can count really really high.

I can almost instantanously approximate the amount of degrees to turn a wheel in order to stay on a path while simultaneously applying appropriate thrust to maintain my bering and velocity.

mfw when watching the shitmentary

Studying theory is pointless. It's better to follow the algorithms and play around with different input combinations on your calculator or computer. Looking at Greek notation all day makes you a homo. Get up and do something.

>>8495930
Bullshit. Studying theory is more than enough to start doing solving problems.

Think about people in your class who are not retarded. Those who do not ask questions to the professor because they get the material. How do you think they managed to answer the first problems of the topic? The only thing they had was the theory so they must have used that and only that. Maybe later they will gain experience and apply theory + experience but non-retards have to start with only theory.

It is retards who immedately start asking professors to solve problems before they have even attempted to try doing them and then in tests they simply mimick the procedure and because of this they fail when doing the trickier kinds of questions.

I remember when we first had to do improper integrals I was sent to the board to do the first one, after just learning the definition of an improper integral.

To solve it properly I had to separate the integral into two. Explicitly I separated an integral from 0 to infinity to one from 0 to 1 and from 1 to infinity.

Then some girl wanted me to check her procedure and I saw she had also separated the integral... but that wasn't necessary with that function. She applied what little experience she had and forgot about the theory.

This is how retards drop out. Try to not be a retard.

>Wahh, I'm going to get a real job

Yeah, fuck yourself OP.

Pure math can be interesting, but it's useless in the real world past linear algebra and statistics.

>>8495736
Stats is cool. I've heard the best degree combination today is Computer Science + Statistics. You'll get a job, be rich, and have a balance of applicable and theoretical knowledge

Pedos only hear what they want to hear, so there is no point in posting in good faith

The cryptology/ linguistics stuff was really good. Felt like 50s and 60s russian scifi stories.

Sadly it went to shit with the bullshit time travel/ seeing through time stuff. Created too many plotholes.
Also it really portrayed the physicist in a bad light. He didnt do jackshit the entire movie. He just acknowledged the amazing alien tech of antigravity and materials and didnt even bother experimenting with it.

>>8495274
my thoughts exactly

>>8495258
"universal language that lets you see into the future once you understand it" was a nice metaphor for mathematics. at least that's what i think they were going for.

also liked the mathematica product placement. apparently wolfram research did consulting work on the film.

Before diving into a proper study of it: everything I've heard is quite popsci-related, I wonder if there's anything to it or if it's purely mathematical.

After dabbling in some string theory basics: it's a very sensible, physical theory that was bound to be discovered at some point. The properties of the quantized string modes so nicely map onto a usual graviton/photon/gauge particle understanding. The fact that internal consistency reproduces the einstein-maxwell equations is also incredibly satisfying. Overall it's just a very physical theory that makes a whole lot of sense.

Shit-smeared brainlet here. Can you share what literature you used to develop a decent understanding of the theory?

I am going to hijack this thread to ask a related question about integrals.

In his pic he has the integral of sin(x)/x from some constant to infinity and that means that the graph of that function changes sign infinitely many times.

I've learned that to get the total area of your graph you need to separate the integral into intervals that are completely positive and completely negative (and absolute value these ones) and them add them up one by one to get the total area, instead of mixing intervals with both negative and positive so that parts cancel out.

How would this work here? The integral has infinitely many changes of sign. It goes from positive to negative, to positive, to negative, etc.

What would you do?

I asked because today I had a Calc II test where I saw a similar integral (cosx/e^x) and I just computed the integral from 0 to infinity and got 1/2 and then asked the professor if that was 'okay' and she told me that she also got 1/2 so I was fine.

But then I separated the first positive interval from the rest of the integral and computed the two integrals and got then an aswer of 1.

What is the real answer? How do you work with infinitely many fluctuations?

Friend of mine did it. I haven't checked if it's right. Wait... Is that you?

No.

>>8495169
thanks. my chemist friend said it was, i'm not sure why

It is the sugar it contains.

Only if n=1

Godel proved that the answer is independent of ZFC, so we'll never know.

obviously not

> I've been searching information about it but nothing seems clear nor trustable enough

Because a planet like that would be so visible to amateur astronomers to see a x10 thing bigger than Earth.

And let's not talk about how gravity and other solar bodies (planets, astedoid, etc.) would be affected for this.

But of course, some people know how to make money about this... for example, just look all the 300 nibiru-channels there are on youtube right now, to dedicated only about this imaginary fear-porn planet.

>>8495070
It was supposed to hit Earth in 2009. Then retards changed the date to 2012. I don't know when it's supposed to hit us next.

Do you ever recognized that many scientists have curled hair?

He needs to record supercooled water freezing with his thermal camera.

His science videos are better than his political ones. Not sure about his Hyperloop one though because he treats it like the physically impossible stuff he covers when it's just safety and logistics that can be worked out.

>confidence interval

What the fuck? Is this some social science or female science bullshit like 'I know I am wrong but I am confident! I am a strong powerful woman who don't need no man!'.

What the fuck. Why not a 100% confidence interval, pleb?
