yes as the earths magnetic field is quite weak so you would need to generate a rather large magnetic field to get a significant amount of force.

answer my question please, do you consider magma to be alive?

a barrier between them works. we would be able to help more if we knew what application this was for.

just thinking about this thread, and i have to ask, seeing as you interpret the crust to be dead, does that mean that you interpret magma to be alive?

that depends on the curvature of the universe. current readings suggest it is very flat so light will not have had time to come round the universe yet

yep. pretty much. a linux system will actually get faster the longer you leave it running because it optimizes the cache and filesystem as you go along.

oh the pre loading system, yeah, linux has two of those, preload and prefetch. they perform slightly different tasks but it amounts to the same, caching your favourite programs on startup.

something similar can be done on linux as well. put your swap partition on a USB drive and you can get a bit more speed. technically, linux has the more versatile implementation as you can do it with any arbitrary storage device from USB flash drives to floppy drives(although floppy drives will detract from performance.

if you're posting properly the posts merged shouldn't affect you except in unordinary circumstances like when the forums mess up a bit and you have a double post.

i am free to say that airplanes fly because of the colour of their cockpit furnishings and not the wings but if i try to implement this my 'plane' would not get off the ground. being correct is not free, it has very severe limits imposed on it by reality.

i imagine PETA would freak if you tried that nowadays IMM herself would probably turn up on your doorstep to try that experiment on you. but, ethical issues aside, it is an interesting experiment, and if done today it would probably be a bit more than a head attached to a heart/lung machine. we could probably keep it alive longer by providing nutrients, artifical kidney functions and so on. possibly even hooking the nerves up to artificial appendages. it would be interesting to see if we could do this with a human head as well as then we could get some meaningful feedback from the patient, although this would be even more illegal and so on. damn ethics, they get in the way of the really cool stuff.

well, its not really the cost of the fuel. its the cost of expanding the power production/storage capabilities of the ISS, you need a LOT of power for ones with decent thrust and power isn't in such a big supply for the ISS its not as if it can just plug into the mains.

talk to the people at ubuntuforums.org. they'll get you set up. Adrian, linux supports more hardware than windows, its just that manufacturers either do not produce drivers for linux or have very poor drivers for linux so they have to be reverse engineered by developers which results in newer hardware not being fully supported. i have 3 machines running linux of various flavours and all of the hardware is fully supported, including dual monitors.

more space. might have some stars in it, might not. whats above/below your dinner plate? might be some chicken, might not be.

a frictionless fluid. its called a super fluid because it behaves more like a perfect fluid than normal fluids like water.

yes it does, the direction of the forces tells you if a force is a force of attraction or a force of repulsion. vectors allow you to not only calculate the magnitude of the force but also its direction which will tell you if it is attractive or repulsive.

I use evolution too. same reason as klaynos.

as i said, simple hydrostatic analysis.... same goes for doGs one, even without considering friction on wither of the two. can't comment of ed's quantum one as i don't know enough about QM

i doubt it as the dose would be incredibly tiny. even if your hypersensitive to it he dose just wouldn't do much.

bingo, you hit the nail on the head there. the outer core doesn't have enough pressure on it to solidify, so it can remain fluid. but the inner core does so it crystalises. this is off topic but it may interest you to know that there are some mixture that are liquid at room temperature but become solid upon heating before turning liquid again. this requires some interesting solubility characteristics.

i can assure you your case is the exception rather than the rule, i mean, you even had to modify your BIOS to boot from the CD, i've NEVER had to do that for a computer unless i specifically set the BIOS to not boot from cd for some reason. if it works in one OS but not the other then it is a driver issue and not the hardware.

no it will not, the only place in the tube that will be at 14.7psi is the bit level with the surface of the water on the outside, the pressure above this point will be 1atm-rho*g*h where h is the the distance between the arbitrary point and the atmospheric pressure line. the positive direction for the height is up. the pressure at the top of the fluid will be that of the partial vacuum. there will be a gradient of pressure in the water from this to the end of the tube which if submerged will be greater than atmospheric. You do not seem to understand hydrostatics properly

the pressure at the valve would be less than atmospheric pressure, the air would keep the one way valve shut. hence no flow. amazing what a simple hydrostatic analysis can do.

YT is still building mad stuff including radiation resistant crops for making beer and nuclear reactors.

well, the ion thrusters for the sattelites don't have to deal with anything close to the friction found at such low altitudes (yes, i just called 200 odd km low). multiple ones could be done but would be very expensive. they have an absolutely crap power to weight ratio. the most powerful ones in exitence cannot even produce a single newton of thrust (getting close though). EDIT: actually there is one that can produce 2.9N highly experimental ones can produce more than 10N but start to lose that ultra high impulse. it also requires 75kW to run which would drain the ISS's power for the months it would require to get back up to altitude.[/EDIT] the trick they have is that they can pruduce a much larger impulse than any other type for the same fuel mass. this is down to the extremely high exhaust velocity.
