well... the only sort of effect i can think of is pheromones being given off by our bodies and then dissolving in the water. but then its not pure water anymore.

LCD's are pretty much all the same now. for choosing one, go for DVI connectors (much better signal) and 8ms response times. that will be clear as a bell and no ghosting effects.

i take it that it was an alcohol free affair then.

how exactly, can it look different under a microscope? as far as i know, molecules are not visible under a microscope. the only way we can view molecules is under an electron microscope and if you have an appreciable amount of water then its going to be a very very messy picture and certainly not a liquid.

yeah the goal posts in science are defined as being in a certain range, we don't know where they are in that range maybe but they're there. new more accurate theories just bring us closer to the location of the goal posts.

you call that a mocking? that sucked. i expected better of the SFN community.

scrape the wood off of pencils and use the graphite from that. or you could buy them from a chemistry supplier.

they use an RCS (reaction control system) for this or have the pannels on a gimbal system if the sattelite has to point down at earth(telecommunication systems) if it doesn#t then the sattelite will not rotate much if left alone.

it will emit some ultra violet an even some x-rays but the amount is negligble most of the radiation emitted is in the infrared spectrum (heat basically) and there should also be a small amount of microwaves and radio. for the distrobution, look up "boltzman distrobution". the peak depends on the temperature of the fire.

Yeah, been meaning to get round to this for a while... so, anyway here i am. mock if you will. in hindsight i should have removed my earphones but my speakers on my laptop suck and it was a really good song(hysteria by muse). EDIT: crap forgot to resize

abskebabs, yeah i'm at strathclyde. you do need to be reasonably good with the practical side but its nothing too complicated. if you know how to set up a still, a reflux condenser, do recrystalization and titrate you'll be fine. (you should be taught these in your first year anyways)

Since when was perpetual downgraded from infinity to 2?

well, we do get down and dirty with the machinery on occasion, but it is mostly designing and improving the efficiency of chemical plants. Say, for instance, a new drug is discovered by a lab(purpose is irrelevant). and you need to produce LOTS of it, a chemical engineer is going to design the process and a factory for large scale production. this is actually a whole lot different from very small scale like in a lab. Half our lecturers wear blue overalls so you might be on the mark with that one. Abskebabs: you missed out the math subjects thats what i don't like.

yup thats an 8 hour shift.

it could in theory be done on the spot, but adapting the equipment for working without a lot of power would be expensive. until we set up a base, we are going to have to rely on returning samples

Well in chemcal engineering(my degree) you have to consider a lot of the economical factors. the business managment practices is part of the compulsory curriculum and the entrepeneurship class is an elective i picked(i needed to pick an elective to get the required amount of credits) it was either that or a language or a biology type class(i haven't done biology for 5 years now)

the C-C bond in graphite(not the one between the layers) is kind of like the C-C bonds in benzene because there are delocalised electrons involved and each carbon only has 3 bonds. this is also what allows it to conduct. nothing miraculous about it. Edit since neil went ninja on my post: the C-C bonds in graphite are actualy stronger than those in diamond because they have some double bond character. although the bonds between layers are incredibly weak. in a diamond however all the bonds are your average sigma bonds. hence it doesn't conduct. and the lattice structure also gives it an appearence of stregnth.

Foundation Engineering Mechanics semesters 1&2 Process Analysis 1 semesters 1&2 Process Heat Transfer semesters 1&2 Process Fluid Flow semesters 1&2 Chemical Engineering Practise semesters 1&2 Business Management Practices semester 2 Process Thermodynamics semesters 1&2 Mathematics 3b semester 1 Mathematics 4b semester 2 Entrepeneurship(Personal Creativity and New Venture Creation) semesters 1&2 sounds fun, no? i don't want to do the business management practices but its compulsory and the entrepeneurship is the lesser of 2 evils

I wonder why you were getting sleepy...</sarcasm> are you wanting to do this constantly or just for a week or so. if its constant its VERY VERY dangerous, your body is not designed to cope with 5 hours sleep a day for prolonged periods. you could maybe take it for up to 3 weeks, maybe even a month, but eventually your going to have a mental breakdown. temporary insanity is a definate and not the fun kind either. i don't recommend this at all.

mooey, the ice caps are not completely CO2 ice, there is still a lot of H2O the CO2 ice comes from the atmosphere freezing.

shrinks the disks so the read/write heads don't impact the surface as often. Its only a few nanometers but its enough to work.

yes earthed means grounded. it means the voltage on it is 0V

well, if its true then the whole field of quantum mechanics and a fair bit of chemistry is complete and utter bullcrap. so chances are its a loon seeing as quantum mechanics(or whatever the current theory is) works pretty much how we predict it to.

the picture of the sun is somewhere in the X-ray part of the spectrum i believe the green colour is a product of the post capture image processing. skeptic lance said everything that needed to be said on the mars picture except that most of the ice is frozen CO2 but not without a considerable amount of water ice as well

Tartaglia, please don't just tell him/her the answer. show him/her the method to work it out, even use an example with different digits if you want, but don't just give it to them on a plate.
