For those baffled, it's from Isaac Asimov's amazing short story, The Last Question. Which pertains to entropy and curiosity as to the means of reversal thereof, and is definitely worth a read.
Maximum entropy is not about molecular motion, it's about energy distribution; basically, all the energy in the universe will eventually become heat, making it a very warm, very dead place.
@QuarterToTomorrow: wrong, it will become colder. It will be a cold, dead place. There was something in the article that mixed heat death and entropy, but I am too tired to figure out what went wrong there...
@yogibimbi: As I understand it, the universe will get warmer on average, which will leave it still a very cold place.
Most of the universe, now, is really, really cold. We happen to be on a bit that's not. In the entropic death of the universe, all energy would be heat, pretty much evenly distributed. The average would be higher than it is now (but still near 0 Kelvin), but there would be no hot spots like us up at 310 K or wherever we are.
So, yeah, it'll be cold and dead. Dead, because life requires an imbalance in energy distribution to drive it; cold, because it will be only a bit warmer overall than the near-absolute-zero it is now.
More useless theory. Theory based on theories that were at one time based on other theories...it goes on forever. Just one small mistake in some hundred-year-old theory way back in the day could be enough throw this all out the window.
No one ever proves anything anymore, they just want their ideas to be heard so they get more research funding.
And in this case...who's gonna call them on it when they're inevitably wrong (again)? As humans we prove ourselves wrong so much more often than we prove ourselves right.
Does anyone really think molecular motion will actually stop before we all destroy ourselves anyway? Put money into some useful research for once.
@Twinder: Or, maybe you should propose a more appropriate subject of research and have some organization or group fund your activity so that you can potentially bring us more worthwhile discoveries.
You guys obviously don't get science, so just put down your computers and your mobile phones and walk back into the thick undergrowth hiding from predators. Why, you may ask.
Well, it's simple, without scientific pursuits (even some of the most basic, like fashioning tools) you would still be at the bottom of the food chain. Just because a theory is out doesn't mean it has no value. The whole point of science is the evolution of an idea, if you're not willing to accept that (or in your case you wish to restrict this) then you have no place using any technology.
FYI, funding usually comes from governments or organisations for science. So yes, these people are being paid. What for? To do exactly what this report is doing. The both of you need to learn to think a bit more than "oh noes, science made a misatake... bad science, kthxbai".
As old Ben Franklin said, we are all born ignorant, but one must work hard to remain stupid.
Face it, your idea for an electric candle, while absurdly amusing, has not panned out. I have watched you make hundreds of attempts now, using a wide array of filaments to no success. As humans we prove ourselves wrong so much more often than we prove ourselves right.. try putting money into some useful research for once.
@sortius: You're barking up the wrong tree, buddy. Is there any particular reason why this comment is directed to me? I'm very curious, as I made no criticisms against any theory, nor did I display any lack of a firm grasp on what a theory actually is.
Harm me with harmony.

Verse 1
Entropy, how can I explain it? I'll take it frame by frame it,
to have you all jumping, shouting saying it.
Let's just say that it's a measure of disorder,
in a system that is closed, like with a border.
It's sorta, like a, well a measurement of randomness,
proposed in 1850 by a German, but wait I digress.
"What the fuck is entropy?", I hear the people still exclaiming,
it seems I gotta start the explaining.
You ever drop an egg and on the floor you see it break?
You go and get a mop so you can clean up your mistake.
But did you ever stop to ponder why we know it's true,
if you drop a broken egg you will not get an egg that's new.
That's entropy or E-N-T-R-O to the P to the Y,
the reason why the sun will one day all burn out and die.
Order from disorder is a scientific rarity,
allow me to explain it with a little bit more clarity.
Did I say rarity? I meant impossibility,
at least in a closed system there will always be more entropy.
That's entropy and I hope that you're all down with it,
if you are here's your membership.
Chorus
You down with entropy?
Yeah, you know me! (x3)
Who's down with entropy?
Every last homey!
Verse 2
Defining entropy as disorder's not complete,
'cause disorder as a definition doesn't cover heat.
So my first definition I would now like to withdraw,
and offer one that fits thermodynamics second law.
First we need to understand that entropy is energy,
energy that can't be used to state it more specifically.
In a closed system entropy always goes up,
that's the second law, now you know what's up.
You can't win, you can't break even, you can't leave the game,
'cause entropy will take it all 'though it seems a shame.
The second law, as we now know, is quite clear to state,
that entropy must increase and not dissipate.
Creationists always try to use the second law,
to disprove evolution, but their theory has a flaw.
The second law is quite precise about where it applies,
only in a closed system must the entropy count rise.
The earth's not a closed system' it's powered by the sun,
so fuck the damn creationists, Doomsday get my gun!
That, in a nutshell, is what entropy's about,
you're now down with a discount.

Dear Mr. Edison,
Face it, your idea for an electric candle, while absurdly amusing, has not panned out. I have watched you make hundreds of attempts now, using a wide array of filaments to no success. As humans we prove ourselves wrong so much more often than we prove ourselves right.. try putting money into some useful research for once.
