it could mean after the lava has solidified, maybe. unless it gives you a heat of fusion just use dH=mCpdT

you can use the effect to make a pump its just not very good for anything though. not too efficient either.

marconi carb? well, thats one i've never come across before. sounds like seafood.

i'd say animals are both intelligent and conscious. perhaps consciousness is a product of intelligence? i don't know. probably never will.

yes. we already have 'weak' AI. programs that are aware of the surroundings and apply a simple set of rules that are influenced by variables in the environment. i wouldn't call the machines conscious but they do have a limited intelligence.

alright, i'll take that reason. they could still be public, it might motivate people to be helpful and get some good threads going.

why is it a nice thing only? i mean if we gave te more persistant trolls negative points (and made them viewable) then it might let newbies know that the troll isn't to be trusted. then again, its your call.

righto

i also can't see a way to add reputation points.

i doubt there is one single database on polymers. especially a free online version. you MIGHT be able to find one on a particular type of polymer but even that is doubtful. have you tried google yet?

and if you got a friend to drink it, it'll expand out through his nose too.

you just observed a nice example of supercooling. what happens is that the the ones in the middle cooled down slower so they didn't have a really big temperature gradient. this caused the fluid to remain pretty stationary and undisturbed which lets them cool below their freezing point and remain liquid. when you moved them, you provided a disturbance that produced a nucleation site which allowed the mixture to freeze. its a really cool effect and makes a nice party trick.

yes but virtual trees mean virtual O2.

thats the same EVERYWHERE not just pakistan.

tree, i think we're trying to apply proper physical laws to unphysical situations here. i was thinking that maybe the extra mass would have came from space dust colliding with the earth(even though there isn't enough up there) so it would already have a decent momentum. although, that would just have buried all the land. if the earth just ind of gained mass in situ then who the hell can say what would happen. things don't just expand from the size of mars to the size of earth without any addition of material.

okay trigger, i'll accept that the earth can vary in size due to known phenomenon(thermal expansion, bombardment and i'll even through in the creation of decay products, two atoms have more volume than 1 usually.). The only one that seriously changed the size of earth was bombardment in the early life of the planet. it took earth from a dust particle to what it is today. in that stage it did expand. although at that time it was a ball of molten rock. as it started to cool it would have contracted but it was also still being bombarded so the effects would negate each other and probably lean towards expansion. since the large majority of the earth (mantle downwards) is still pretty damn hot from the bombardment i think we can assume that it isn't varying much in terms of temperature so thermal contraction isn't going to be very noticable even over a billion years or 2. either way, if the earth expanded from a pangea in the time of the dinosaurs call it 128 million years ago. to the size it is today the shear amount of mass needed would have liquidized the earth again. and we can only assume that the earth was even smaller than that before, so maybe 3 billion years ago earth would have been smaller than an atom.

well, the orbit around the earth wouldn't be affected much if the earth maintained the same velocity.

not so much our orbit around the sun but the moons orbit around us (or lack thereof if it was true)

well, if good doctors are also biologist it doesn't mean they have to be good biologists. they just know a small field of biology. the same works up the rest of that chain.

oo oo how about the fact that pythagoras calculated the diameter of earth to within a few kilometers of what we know it to be today? the error he got is well within the error margin for his measurements and its enough to bork expanding earth because the earth should have been well smaller than that. also, what about the observed subduction zones and the mid atlantic ridge? the growing himalayas as well. dear god the stupidity. it hurts my hungover brain. if i said what i wanted to say to you right now i would probably get a lifetime ban so i won't. seriously, we know science doesn't have the perfect view of reality but it is a self correcting and working approximation of reality. as new evidence is uncovered the theories are adapted to explain this. expanding earth is discarded through actual observations of geological processes, and the fact it requires massive amounts of matter to be deposited on the earth with no obvious source and the planet is much colder than it would be if it were falling from space. also, there is no government propaganda here. what would the political purpose be? the continents have not moved very far in the 200,000 years humans have been here and insignificantly in the past 100 years which would actually matter for political reasons. as for global warming, there are a multitude of factors and CO2 is the one that has increased the most. thus it has the greatest effect even though it is not the most effective.

well the question seems like homework. forum policy is to point you in the right direction and not to just give you the answer

correct me if i'm wrong here but don't muons have a mean-life instead of a half-life? i'm pretty sure i read something about the detection of muons at groundlevel (something: that old 100% reliable source ;P) where the muons had an average lifetime. which isn't the same as a half life.

use open office? never seen any mathematical discretions with that

no he said he wanted the impact force it would have on the pole. i'm not sure how you would go about calculating that though.

well, i've never known a noble gas to conduct electricity(appart from when its ionized but thats a whole different shebang). or be solid at room temperature. so you can't use them. its fine that you were a bit confused, it happens to the best of us. you got something out of this and thats the main point.
