water IS compressible. not by much but you can squash it to the point where it will form a type of ice.

i think we can assume by 'aircraft' that 'spacecraft' are outside the requirements. as for the fighters with the excessive thrust, there was nothing specified about the amount of difficulty in launching or landing requirements so i guess we could include them

how about a Xe cylinder. one atom of that has more mass than a couple of water molecules

yes it is entirely possible. the JSF(joint strike fighter) or X-35 is the closest we have to one at the moment. it can land vertically and can take off in a really short space(not quite vertical takeoff i know) and its super sonic. eventually we will have supersonic VTOL aircraft.

yeah this happens. its more like a rocket than a jet though. if you could get it to go in a straight line then there is the potential for a kilometer or two of flight with some of the bigger cylinders. typical pressures are around 300Barg (rougly 300 atmospheres). most cylinders have a big plastic bit to prevent the neck being smashed off.

civil engineers get stuff that the architect designed built by using contractors. i think thats how it works.

sounds like thermal shock. i doubt the top would be airtight enough to cause any significant buildup of pressure. if nothing cold enough was touching it then the only thing i can think of is that thermal expansion against its frame produced enough force to shatter it although that is very very unlikely as it would be factored into the design.

can we choose not to answer that?

yes and you obviously rushed into it without thinking as you didn't nominate me for anything.

oh come on snail. you know what the chat is like. its a big insult fest. we don't mean it(well maybe some of the stuff about stu) you should know by now the combined mental age on the chat is maybe around 5 years

b) and its because of friction and the viscosity of air. if it didn't then we would have 900 mile per hour winds at the equator. not a nice situation.

in an infinite universe there could be another you going 'oh god you'll never believe how much of a pillock another version of me is being'

you mean you don't have black-hole insurance yet? i can sell you some for a mere £500. ***kicks the insurance salesman out of his house*** if these were going to happen they would have happened naturally already. by the time we can shove more energy than nature can into a particle then we can wonder about what happens.

you just know this is a sad little geeky kid of about 11 staying up past his bed-time. probably thinks 56k modems are the best thing ever and has few(1 or 2) friends if any. turn the computer off, take a reality check and go do something outside.

the electron shells combine to form a lower energy state(more stable) this is accompanied by the release of energy.

did you ever think that the orbital variations(which are well understtod and pretty simple) may be a cause for the natural heating and cooling of our planet?

how about force every member who hasn't voted to vote before they can do anything? it isn't a democracy afterall

still suspicious though. but i guess i owe you that fiver anyway. ***sends 5 pings of death over capns way***

hmm, so linux itself only violates 42 'patents'. it won't affect webhosting prices till microsoft prove that it violates patents and if MS does that then the software will be changed so it doesn't violate anything. so i'm going to go with, no. this won't affect webhosting fees.

math guys can be fun. they usually have some interesting personality traits that only make an apperance when theres alcohol involved. it makes up for the sheer dullness of the subject.

hmm, usually its us(chemical engineers) discriminating against physicists because a lot of them can't hold their alcohol and are surprisingly rubbish at pool even though they should understand the principles behind it(you'd be amazed how many of them hit the ball on the wrong side)

a real application(although a simple one) would be a graph showing the variation of pressure in a system with respect to temperature and volume. say the x-axis is temperature and the y-axis is volume the z axis would be pressure of course.

ahh so this was all a spamming ploy. who wants to bet a fiver that tim and intensive are on the same IP and macaddress?

yeah, really. didn't mean that i hadn't already had several times too much and tried to spark up a conversation about the mechanics of donuts with my wall.

ahh my favourite of the non-existant ex-russian states
