I'm really curious about nuclear fusion. If by tomorrow, the US decided to dump 100 billion into fusion research, could we expect significant progress within the next 10 years? Or how about 200 billion? With all these promises you read about in the media about fusion, shouldn't there be a huge global movement to make fusion a thing? I mean, shouldn't it be the #1 priority above ALL else?
nah

Unlike in video games, generally you can't solve scientific problems just by throwing money at them. You have to come up with an experiment first, and then that costs whatever it costs, and it may or may or may not work. You could allot $100 billion for fusion research, but we would have nothing to spend it on because...

Yeah, good luck with that. Before we ever even dream of progress, we must fund analytical number theorists.
Any recommendation for a begginer in this markdown language? Thank you.

Nice bait.

I guess she meant markup.
Today I just realised something. For a dimension to truly be a dimension it needs to be perpendicular to all other dimensions. E.g. In 2 dimensions the x coordinate system is perpendicular to the y dimension. In 3 dimensions the z axis is perpendicular to both the x and y axis. Therefore it's not possible to have a system with dimensions greater than 3 because if you add another there's no way for it to be perpendicular to all three other axises. Now where is my Nobel award?
It can be perpendicular with a dimension greater than 3 based on the scalar product you defined.
If P and Q are vectors of a n-dimensional space :
P _|_ Q \equiv <P,Q> = 0 \equiv (P,Q) = Arcos<P,Q>/(Norm(Q)*Norm(P)) = Pi/2
I meant dot product.

you are seriously responding to a troll thread like it's real.

How long until we see these sorts of hoverboards

with 10 minute flight times? I believe that once that mark is passed they will become commercially viable (extreme sports,emergency response in areas with shit roads etc.)
They'll be banned for public use instantly after the first few deaths.

>emergency response in areas with shit roads
not this bullshit again
the quickest emergency response (one that can actually carry stuff) into an area with shit roads is a paramedic helicopter

How do we know what's in the middle of the earth? No one's been down there, right? Realistically, it could be hollow and have a bunch of dinosaurs living down there.

Not a rock doctor, but I'm pretty sure you can estimate the density of layers of the earth via seismic refraction.

Where does used energy go? If it doesn't go anywhere, and still exists after being used, shouldn't infinite energy exist?
well you see, Billy, the there is a very important distinction between usable work and heat. The laws of thermodynamics dictate that the latter will comprise more and more of the energy in the universe until no usable energy is left, and no work can ever be done. This is called the heat death of the universe.
Energy isn't "used", it is transformed into a different form. The amount of energy in the universe is constant.

Can anyone recommend textbooks/offer advice on higher dimensional integrals? ( d>3)
I've no luck googling/skimming through other books.
>>7844464
Anon I would give up your search.
Only a few of the most brilliant professionals in the world have ever been able to evaluate a triple integral.
No one has ever solved a quadruple integral. In higher dimensions we can't even begin to formulate how one might approach a beginning of a solution.
>>7844464
Look up "vector calculus" and "multivariate calculus".
>>7844470
Engineer here with a question (inb4elitistmathfags), what's the difference between the triple integrals that I've evaluated (for classes like vector calculus and electromagnetic theory) and the triple integrals you're talking about?
How else do you find the volume of an irregular three-dimensional shape?
What are the most well thought out theories of "why" this universe exists?
Obviously this question falls more to the realm of philosophy than science, but I feel that scientific minds are perhaps the only ones capable of tackling it, even if not through science.
I've been reading John Wheeler's Beyond the Blackhole, and also Roger Penrose's fanastic lecture here, https://www.youtube.com/watch?v=kbtxndUJHZI.

What's MIT like? Is it full of nerds that invent crazy stuff just for fun, or is it just like any other uni but with more work? What are the best unis in the world like? Do people there do very wacky stuff instead of drinking and fucking like anywhere else?

420, now fuck off. I just want to know what life is like there, I may want to apply there, because the universities here are terrible so it's not worth me staying here. I just want to know if people pretty much do anything they want for science as I imagine it would be.
>>7844051
I have a friend in MIT currently and I've applied (although I can't really say I'm feeling confident about my chances) and what I've heard is that it's a bit of both, wherein the classes have big workloads but still people find time to work on personal projects. And I mean the school is fucking loaded so getting resources to create something is not too too difficult if you have a good thing going
