  1. umm no. the way fluids rotate has more to do withthe geometry of the vessel and/or the direction of a stirrer than if it is under pressure. if direction of rotation were pressure dependant we should find examples of the the direction of flow varying with depth in a vessel or even ocean where no extraneous factors(like ocean currents, or pumped streams) can be responsible.
  2. -273.15*C according to every bit of literature i've ever read. or even experiments where we derived it empirically, though they were not accurate enough for the two following decimal places. your chem teacher is going to know this value well, it is the preffered temperature scale for chemistry as it makes the mathematics a whole lot easier.
  3. you are holding the magnetometer perpendicular to the field direction. of course it isn't going to work. try rotating 90 degrees.
  4. well no. seeing as it has no rest mass it must always travel at the maximum possible speed or else it would undergo infinite acceleration till it got there anyway.
  5. i will once the leprechauns have left. they're touchy about that sort of stuff. the giraffe doesn't mind though.
  6. gallium is pretty safe. or at least it has never caused enough harm for some to onclusively say it was gallium. just use normal precautions and don't store it near any of the substances in the 'incompatibles' list. the guys metal alloy sounds an awful lot like woods metal. it is far from unique but it does behave similarly to gallium.
  7. indeed OSX 10.5 is much much better than vista, and it will work with everything guaranteed.
  8. still isn't going to behave like you think it is. not to mention you are ripping off the designs of other people nearly exactly.
  9. well, if there is something that can arbitrarily put the laws of physics on hold then the laws of physics do not hold and we can go have tea on the ceiling of a giraffe since that makes about as much sense. also, there is no 'out of universe' frame. there is no transfer of anything across any boundary that might exist(we don't think there even is a boundary per se. and any observer would be part of our universe by definition anyway. you need a valid frame to apply physics.
  10. obviously he is no physics major if he thinks 2 billionths is lower than 1 billionth. if i have 0.000000001(a billionth) and i multiply it by 2 i get 0.000000002(2 billionths). i don't know what he means by 'subtract one' that would give -999,999,999,999 billlionths of a second to go 2 feet. which seems dodgy if light starts going back in time after a foot.
  11. yes well, it is hardly the most accurate book. a lot of it is 'dumbed down' and has all the really technical parts of it stripped out so normal people don't collapse into a gibbering pile of mush at the sight of the mathematics behind it. quite a lot gets lost in the translation from technical language.
  12. well it would still be impossible due to the rate at which the universe is expanding and the fact that there isn't really an edge anyway. i mean, sure wou could make a loop that would be 52 years ship time but you wouldn't have gotten close to going round the universe. you would actually have further to go than when you started.
  13. okay, equations are really useful tools in physics, maths, chemistry, well just about every where. they work because things tend to have basic mathematical relations to each other. they are composed of variables and operators. in our case we have the variables, speed, time and distance. and the only operator is a division. the time is takes you to travel a certain distance is the total distance you have to travel, divided by the distance you travel per second. makes sense. so, we can construct the equation time=distance/speed this equation will work for any distance and or speed you want. all you have to do is keep the units consistent. if your distance is measured in feet and your time in seconds your speed would need to be in feet per second. using something obscure like furlongs per fortnight would give the wrong answer. you have a distance(2 feet) and a speed(983,571,056,159 feet per second) so, the distance variable is equal to 2(that means instead of writing 'distance' you can just write 2 and do the same thing with speed. so you would end up with time= 2/983,571,056,159 and the answer will be in seconds.
  14. just put a 2 in that little equation i gave you and out will pop your answer. just like that.
  15. well, seeing as it is not physically possible for a massive object(like yourself or a spaceship) to reach the speed of light then you can circumnavigate it in as long as you want as the laws of physics obviously do not apply.
  16. what? you can't do division? or is it unit conversion thats getting you?
  17. time=distance/speed. thats all you need to work it out. you know the distance and you know the speed.
  18. whats wrong with using crystals anyway? the whole point is that they are ordered structures so it is relatively easy to back track and see what happened.
  19. i think the move to full 64-bit is defininately a step in the right direction as pretty much all new hardware is 64-bit now. might as well use it if it is there. still, nothing is there to get me over my inherent hatred of macOS. i still find it frustrating to use. for numerous reasons.
  20. so basically you just copied the orion drive, replace lasers with even more power hungry ion accelerators and hope nobody would notice this bit plagiarism? Additional, on further reading, there was a variant that uses electron beams to ignite the fusion pellet. the only significant differences i can see between the two drives is that square wants to inject the fuel in a plasma state rather than in a pellet. which i imagine would be rather inefficient due the vacuum of space and the tendency of positive charges to repel.
  21. if it is vector addition the value could be anywhere between 0 and 2.
  22. same thing for all intents and purposes. though you can get different wallpapers on each desktop. then again with a bit of compiz magic i can do that on linux as well.
  23. technically if you remove the wire you will have an even simpler accelerator. heck, even a charged chunk of whatever would do.
  24. i used it once, noticed how 'spaces' seems much the same as the 'workspaces' in linux do. also seen them pawning it off as 'new'. i didn't really see anything impressive. just seemed like a shinier version of the previous iteration of macOS

    Omg!

    aren't nuclear reactors supposed to be critical anyway? isn't that how they work by sustaining a chain reaction?
