>What is happening in the Energy sector right now

American perspective on domestic trends:

fossil fuel is heavily subsidized to the point it is not representative or a real free market what so ever.

Fossil fuel special political interests groups heavily fund all major political party candidates to ensure the continuation of their subsidies.

Laws are being passed on the state levels to make point source renewable energy systems (roof solar panels) impossible to own/operate due to convoluted regulations designed to maintain fossil fuel monopolies.

All financial and political powers are aligned against renewable energy development and will remain so for the for see able future.

Also President Trump, I do not believe, will have an interest in spending political capital to address this issue.

So you want a job or are interested in making money in the energy sector maybe look into land leasing in the newly accessible northern polar region oil fields. I anticipate lots of money will be made extracting those relatively easy to tap deposits.

Solar has pretty much just hit its stride, its probably too late to be rockefeller but, you can still make good money (as an EE for example) all over the world in it

This is not true, I'm actually in the solar industry and I'd say the only place this is a problem is Arizona, and it's not so much that they're impossible to own, they simply aren't profitable. Furthermore even if all said powers were aligned against renewable energy, which they aren't, I and many other professionals believe the markets will be going strong regardless.

>>8546943
Yes, that's their main feature.
You can (probably, assuming exotic particles) warp spacetime arbitrarily fast.

Of course it costs incredible amounts of energy, to the point it's not worth it even if it's possible.

>>8546946
How much energy? What would the energy required be comparable to?

>>8546955
>What would the energy required be comparable to?
something between the mass of jupiter and the entire energy production of humans a whole year. Even the best case scenario (which is not exactly proven to be possible) is completely unfeasable.

>>8546867
No.

>>8546867
It's probably a width value. I'm not going to bother.

>>8546867
You're just having a pattern and then doubling the distance each time between them

>>8546719
I know plenty of people who are very aware it makes you stupider and they couldn't care less. Why do you?

Also, as far as I know you can't clean out your lungs. Again, they don't care about this either, why do you? You're going to die anyway.

Emphysema is when your alveoli are permanently impaired due to their shape changing so they're less effective in getting oxygen into your blood. It is not simply having smoke in them, they can't be cleaned off.

>>8546719
Do a lot of cardio. Your lungs start healing the day you quit smoking. It just takes time. I was unaware MDMA had acute neurotoxicity. I always attributed my decline in abstract reasoning to heavy LSD use.

>Once time has been "rewound" sufficiently inside the bubble, we could move into it

No, not theoretically possible.

Evolution is an example of reverse entropy, chaos to order. Life itself is the exception.

So is the more order representation here from the time prior to the Big Bang?

About 30 IQ points, minimum.

>>8546247
this sadly

cool programmers are 30 IQ points smarter

no one believed in your ridiculous endeavour.

Rest in peace, OP
It was a valiant attempt

Kek, I (barely) passed my first three analysis courses while attending <30% of the lectures and studying only 4 days per course.

Those 4 days studying per course were very intense on the other hand (16 hours per day and lots of coffee).

So the hyperloop meme is dead already?

>>8546043
For science!

>>8545987
It got me out of having to take courses with people who had no interest in academics.
Also, it made the school staff give us extra leeway and my friends and I would just skip classes every other day. It was fun.

>>8545995
This.


Also, I do think compared to the AP classes I took, it prepared me for uni better. The grind for exams got me a lot of the study tactics I needed for grinding for midterms and finals, and the actual materials covered ended up really in-depth. Chemistry in particular covered pretty much all of first year uni chem and a good portion of organic, which essentially made it so I didn't have to study all that hard in those classes.

What's your beef with it, OP?

>>8546008
I figured if I was going to learn all that shit in college anyway why bother with all the extra shit I don't need. English for example is stupidly emphasized and I only need it to write reports.

its already happening mate, i have a relative who specializes in the field, china, brazil, and the us let their cows essentially drink the stuff.

there will most likely be a worldwide pandemic in our lifetime where billions will die. Not even hyperbole

>human race will become too resistant to antibiotics

sci pls

>x(x-1) = 0
i meant = 1

I've got this:

>0:
0(1-0)=1 obviously not
>1:
1(1-1)=1 obviously not
>t:
t(t-1) = t^2 - t
subtract irreducible polynome t^2 + t + 1 and I get
t^2 - t - t^2 - t -1 = -1
1 = -1

now is 1 = -1 then t is a root. Is 1 = -1 though? I don't know when I should use modulo 2 and when I should use modulo t+1

>t+1:
(t+1)(t+1-1) = 1
t^2 + t = 1
subtract irreducible polynome
t^2 + t - t^2 - t - 1 = 1
-1 = 1

which works too in mod 2

therefore roots are t and t+1

is this right?
Why am I using modulo 2 though, and not modulo t+1

If [math] F [/math] is a field, [math] (F - \{0\}, \cdot ) [/math] is a group, so every element of F other than 0 should have a multiplicative inverse.
In particular, F(4) isn't a field because 2 doesn't have an inverse.

x^2 = x
x = 0 is a trivial solution.
If x isn't 0, x^-1 exists so multiply both sides by x^-1 :
x = 1
x = 0 is a trivial solution.
If x != 0, x^-1 exists. So multiply both sides by x^-1 to get:
x = 1

Honey, you're opening Pandora's box right now. There are entire courses on entropy alone.

To help answer your question, no it does not break the law of conservation of energy. In terms of a mechanical system, a steam engine for example, there must always be a heat transfer out process to return the system to it original state, but both the source and sink exchange the same amount of energy, one losing energy and the other gaining the same amount (assuming no friction and no ambient losses).

In terms of the whole universe, energy is always conserved even if it is distributed evenly, down to individual molecules and atoms. Whether it be the kinetic energy or even potential energy between individual atoms, it's always conserved.

Sure you could go out into deep space in 10 trillion years after the heat-death of the universe and scoop up a bag of seemingly nothing, whatever little particals you scoop up would still have SOME amount of energy to it. The issue is that the amount energy is so negligible, that it would have no meaning to us; no practical use or purpose.

Not sure if that fully answered your question, but hopefully it clears some things up.

>>8545293
Entropy is disorder

>>8545293
Entropy is essentially a transformation of energy in a system so no problems with conservation.

Also, temperature is a measure of velocity, so entropy is closer to being unit less than anything.
