while i have no problem with the whole universe expanding thing, i have qualms with the balloon idea. you take an uninflated balloon, draw a dot on it, and blow it up. as well as the balloon increasing in size, the dot does also. if (ignoring the X^2/3 law :P) the human body was expanding...

thg.de just made a rig with 2 dual core versions of these, in SLI. quad core graphics. 1800 bucks for the cards. or you could get a whole pc. I know which id choose.

sorry if this sounds a tad retarded but astronomical topics arent my forte...how do know if something is red-shifted without prior knowledge? say you've got light emitted from galaxy far far away at 500nm, and it ends up on Earth at 510nm. how can you differentiate between 510nm actual...

really? no-one?

hiya a few months ago i got a canon g3, upgrade from a eos 300. first stab in the digital world. now with non digital cams you had a shutter release input, which you could build your own sensors and whatnot for, for taking high speed pics etc etc. it was pretty much a case of applying the...

can anyone explain how this little baby works as a reducing agent? I've heard rumours of H- ions, but that's just weird

no i can attest to this observation as well, I've thought about it to no avail. i think he's talking about when its roundabout 2-3am, late into the night, so there's no sun lighting the clouds just below the horizon. the clouds do appear a dark red that is v bright compared to, say, a normal...

that doesn't plot that relationship as a straight line though does it? i was under impression you had to transform [said equation] into a y=mx+c type form

i have a deceptively simple question you see: X^3 = (cY+d)^2 where c and d are constants, with x and y the variables. how would you plot the 2 variables as a straight line graph. I'm having an idiocy attack and can only think "log it..."

make y the subject of the 2nd one, equate the two, and solve it like a quadratic...? ie. x+2=x^2-x-6

anyoen know how to expand this? i can't think of any obvious way...

there is actually a published printed manual on how to survive zombie attacks, saw it in waterstones (english book chain)...look on amazon. myself, id prefer an m-14 with APLP rounds (can't remember exactly what it stands for, but they pass through hard objects=walls, wood etc, but fragment...

hi guys, doing damped and forced harmonic motion at college at the moment, but i don't do further maths...hence I'm a tad behind compared to those who do (half the class). we don't need to know it for the exam itself, but you know...curiosity. does anyone know of any good online resources...

looked in books/googled for info about this...i know what it IS, but don't understand why it happens. anyone?
