Engineering is a pretty big subject. if you can tell us the type of engineering oyu're interested in and possibly what type of references your looking for then we can help you more.

its going to be 2 significant figures with a rough error of +/- 0.25 -ish.

yeah, a safER level. its still pretty dangerous stuff.

heh, in chemical engineering cubic metres is the most appropriate unit for most cases (in a couple of centuries i wouldn't be surprised to see cubic kilometers up there as well.)

white gold is actually an alloy which is pretty much just a metallic mixture solidified. or it can be normal gold plated with rhodium and palladium which isn't an alloy or mixture.

all coffee tastes like mud to me. no idea why. i really really like the smell of it too.

i used to drink tea with milk and sugar, the works, but i just gradually began to take less and less (no known reason) and i've hit the furthest i can go, no milk, no sugar. i'll still take milk and sugar on occasion but not often, usually once every three months or something.

okay imagine you have a molecule of hydrogen. A very simple molecule consisting of 2 hydrogen atoms next to each other with one single bond between them. the bond axis is an imaginary line that runs through both atoms and along the bond. thats pretty much it. it can be applied to any bond(even double and triple ones) in any molecule nomatter it size. if you still have questions just ask way.

ahh, i thought he was talking about spectral emmision lines, hence absorbtion lines seeing as they are the same phenomenon only in different directions. i was actually thinking o a light to shine through the torso but thats cos i was slightly bored and it would include all parts of the body. ace, the white light source i was reffering to has nothing to do with 'spiritual experiences' its merely an objet that emits electromagnetic radiation pretty evenly at all wavelwgnths. particularly in the visible light region for this experiment as that is where nearly all of the absorbtion/emission lines are.

so your basically saying that if you have a white light source bright enough to shine through a human you'll see spectral absoption lines. thats pretty damn obvious though it would probably kill the person from the sheer amount of energy s/he would absorb. this would not give rise to unique spectral patterns per individual as the chemical composition of humans seems to be pretty much constant with ratios varying only with diet. even with other species you would see identical absorbtion spectra. basically, its not a rare and unique phenomenon, its as common as muck(commoner actually since there is more than muck in the universe).

its a socio-psycological experiment. or at least thats what we want you to think.

and indigo obviously has no idea how science works. step1: observe step2: hypothesize step3: experiment step4: go back to step1 and repeat. step5: nothing gets to step 5. ever.

wow, i thought there were many types of tea plants for green tea and black tea. oh well, guess you learn something new everyday.

dude, you do realise that they launch from a floating platform and not under the sea right? or, was it a horrible attempt at irony?

could be either or both, i drink a lot of red wine too and that has a lot of tannin as well.

i drink my tea without milk anyway. just a teabag and boiling water is all i need.

The public transport here in scotland is a right mess. i use it only out of necessity. every morning i get either the 8am or 9am train to glasgow from my local station and the trains are always packed. now, the trains that run on this route come in two varieties(other than old and crappy and new and shiny) 3 carriges and 6 carriges. both the trains i need to get are the 3 carriage ones. i don't know why can't the shove another 3 carriages on and then the train into glasgow might be plesant. plesant meaning not crammed in like sardines (literaly). coming home about 2 pm there seems to be an abundance of 6 carriage trains on the line though.

well, once they put a couple of sheets of plywood over the big gaping hole thats likely there i'm sure they'll be fine. might want to stick on some ducttape and rubber bands to make sure though.

what the fizzycist said.

uhh houston, we're going the wrong direction.

Work = Force x Distance. always go back to basics. I assume you know how to work out the force on the electron and you know the distance between the plates.

okay, imagine a continent about the size of north america covered in a slab of ice about 2 and a half miles thick. thats how much ice we're talking about for land based ice(and hen it melts the land is going to rise up a bit because of the great weight thats been taken off it, it happened in the UK after the iceage, it'll happen in antartica) the sea based ice is considerably less but still a heck of a lot of ice.

my neighbours cat, along with the help of three other local cats are out to get me. i just got attacked by all 4 of them walking home today. its a bloody conspiracy. i thought cats didn't hunt in packs.

never heard of that one either. it would also be very hard to determine the lifespan in that case. and, it would say that an athelete(breathe a lot faster when training) that lived to 60 would have a longer lifespan than someone with a very relaxed job and never got worked up (slower than average breathing) but lived till 65. years works. stick with it.

umm, just an observation from 1am, but aren't centripetal forces(in this case gravity) always acting towards the axis of rotation by definition?
