It's probably a large-ish vent thing, which would be pretty hard to break or clog enough to stop it from working.

Sounds like a challenge to me...
Thermodynamics time.
You know that equation that tells us that heat transfer (in joules per second) via a rod is equal to the area of surface x delta T x something I can't remember, all dividing by the length of the rod? Well, when the length tends towards 0, heat transfer tends towards infinity. this means that, when an objects enters in contact with another object directly, it transmits infinite energy per second. I'm guessing since we consider heat transfer to be continuous so we just take that infinity x positive infinitesimal is an indetermination?
Sounds interesting, could you tell me more about this fascinating phenomena?
Sarcasm? 'Cause mate, I don't know shit about thermodynamics, just the really basic shit, that's why I'm asking v:v:v
guys I'm gonna find a way to travel 99.999999999% the speed of light until armageddon happens and jesus comes to rapture me up and I'll go "NO IT'S NOT THE END TIMES YET IN MY REFERENCE FRAME"
What if you accidentally stay at top speed for a millisecond too long and you overshoot by a few billion years?
The rapture already happened what's the difference
You won't be able to diss Jesus.
sure I can just really slowly
I read some book when I was like 11, and it had this really interesting concept on it.
these people were launched from earth and put to sleep for thounsands of years in these cryogenic storage things, but one kid's brain doesn't turn off somehow, so he's stuck there for thousands of years unable to move, but completely awake.
By the end of it, time has seemed to speed up a lot for him, so everything he does is really slow, and he perceives everyone else as moving really fast.
I wonder if you were somehow able to live for thousands of years, would your perception of time speed up?

Your perception of time DOES speed up as you age.
Think about it, when you're a kid things like the summer holidays always seemed to last for an insanely long time. You'd wake up every day and the day'd seem to be like... 3 or 4 times as long as it seems when you get older.
Then as you get older, during December of everywhere everyone starts quipping, "man, this year went by fast!"
Apparently it's because as you get older every individual year or day represents a smaller portion of your life than past years/days did. If you're 100 living an extra year only adds an extra 1% to your life. If you're 1 living to 2 doubles the time of your life! By comparison in that year you've experienced, learned, and seen a shit load more than you could between the ages of 100 and 101.
Makes sense, the younger you are, the more you have the learn.
But I'll tell you this, if someone was trapped inside their own body, fully awake for 1000 years, the first thing he would do would be to start screaming at the top of their lungs and kill himself, even if the brain would defend itself with an accelerated time sense.
Sorry, I worded it badly
I know it speeds up, but would it ever get to the point where everyone around you seems to be moving at an incredibly fast pace, and to them you are moving incredibly slowly?
Moment to moment your perception of time doesn't really change, it's just in the long run it feels different.
I always find it laughable when I ask someone (like a teacher when I was at school) how magnetism works (and I mean at the fundamental level) and they start their explanation with something along the lines of:
"Imagine every little electron acts like a little magnet..."
Really? You're gonna use the properties OF a magnet to EXPLAIN magnetism? Circular logic FTW.
that's a pretty bad question though
particles exchange virtual photons with each other and that's how a force is created
Hey, if the photons for both EM forces are the same? Is it the direction of the photon? The field lines' orientation? But for that to happen, photons would have to appear behind the test charge for at least one type of force. How can a charge fuck shit up everywhere in the universe without any interaction? Same for gravity, I guess.
What?
A negative charge will push away a negative charge, but attract a positive one. How, if both forces are carried by the same particle?

It's not a bad question. Questions that fundamental are basically the basis of trying to develop something like a GUT.
no it's a bad question. It's far too general to have a good, meaningful answer.

"how does x work" seems like an okay enough question but if you ask it enough it has to turn into a "why are things this way" question. "What mechanism is responsible for electromagnetic force" is more precise and in this case it requires a working knowledge of gauge theory I don't have so I can't really answer your question mountainwatcher
[editline]21st July 2011[/editline]
It's like, "Why does shit have mass" (because it fucking does) vs. "what mechanism is responsible for giving matter mass" (probably Higgs)

:science:
"Because it does" isn't a proper answer, even for that wording. A proper answer would be "because the mechanisms that governs it allows for it" which is not the same.
Also, I was thinking (I think the pressure-thing on ice is wrong, it's now explained with friction or shit, isn't it?) if that's true, other solids should melt if you shoved air inside of it, forcing it to expand, or fluids should evaporate in the same way.
yeah that was exactly the video I was thinking of :D Feynman was such a baller
but don't worry you're right stlungle that answer makes me want to punch newborns

Worthy of a repost.
There's a difference between asking something like "why is the sky blue?" which is a simple question with an answer that you can really go in-depth in, and asking something like "why do we see it as blue", which you can really only answer "because we do"
Some questions just aren't that great.
Not really, you can still go in depth about the nature of consciousness with the second one.

ok so disregarding the fact that it is just an example, and not one that I carefully picked out, there are [i]still[/i] some questions without real answers.
Only ones I can think of is why happiness is good and why formal logic is correct.
I am currently constructing a demonstration IEC (inertial electrostatic confinement) fusion reactor that will be capable of nuclear fusion, however I don't have an advisor who's certified to obtain the gas I would like do use (deuterium).
I have a couple questions to ask if anyone here has ever attempted something like this:
1. Can deuterium gas be acquired through a university on my behalf?
2. The last component that has yet to be fit is a diffusion pump to further pressurize the chamber in order to produce measurable fusion. I have a roughing pump right now but this creates a vacuum of only a few dozen millitorr (increasing amperage within the inner grid doesn't burn off excess air even at 50mA [limit of my PSU]). I need a diffusion pump to obviously bring the vacuum down to less than one millitorr. Can anyone familiar with vacuum systems possibly recommend an affordable pump? Since I'm using a roughing pump as well I can keep the cost down and purchase a booster diffusion pump but I just can't seem to find anything on ebay right now as far as used and affordable pumps can go. Are there any machines that incorporate diffusion pumps that could potentially be salvaged from scrap yards?
Also, I am a member on fusor.net and I have looked around on there but the only diffusion pumps I can see being recommended are very expensive. I'm a student and can't afford to spend 500 dollars on a booster pump alone and in the FAQ it states that a pump of this type can be purchased used for $75, but I have yet to actually find this.
Jesus fuck, that's amazing. What's that for? Energy engineering?
