chemistry definition of chemical: substance composed of atoms and/or ions. also includes single atoms/ions.

doesn't that go against EVERYTHING your nation has accomplished in the last few centuries? think its time to have a new revolution over there.

you have a flaw here. you replace a variable, V, with a constant, c. justify this substitution or you cannot say E=mc^2 was derived from these two equations(and we know that it wasn't). also, why do we have to do trivial math problems for you to post equations? post them or shut up.

if they are in the relevant field and are reading scientific papers in english then their technical vocabulary is going to include any words they come across. if its not then they are probably going to have to learn it anyway. the fact of the matter is that the words used are used for a reason. they describe some concept not easily expressed using simpler words. either because they are too ambiguous and have multiple meanings(which would likely be more confusing for a non-native speaker). if using simpler words were adequate THEN THEY WOULD BE USED. i bet nobody complained when television or car were introduced to the language.

we are pretty sure they have sunspots but we do not have telescopes powerful enough for direct observation yet.

i think if you are only using one source for research(be it wikipedia or somewhere proffessional) you are not doing it right. any good research should use multiple sources.

i think it is a perfectly viable source for an overview. i use it purely for the references it gives and then use them.

thats not a wavelength you pointed out. the wave length should be from where the lines are densest to the next part where they are densest. the amplitude is how dense the lines are at the peak versus how not dense they are in the trough.

Some graphics cards use the system RAM but those are generally the less powerful and integrated graphics chips rather than a seperate card. but the only purpose it serves across all PC's is as a fast cache so it doesn't have to read/write from the really really slow harddrive. Bookworm: try being helpful and interact with other users not just fob them off on a link to wikipedia.

the thing is, simpler words tend to be ambiguous, have multiple meanings and so on. so, you lose precision. the words used were invented for a reason.

i'd be in favour of you guys lowering i. when your underage it is EASY to get booze. i done it her in the UK before i was 18 and i managed just fine in vegas where the legal age is 21 and i'm only 20. openly drinking is much better than having to drink in secret. its safer.

the s-block consists of the alkali metals and alkali earth metals. if your looking at the periodic table its the two colums on the left. where the element is placed depends on the number of protons. it could be just below francium or radium or it could be several below them

its only gobbledegook if you don't know the background, and if you don't know the background you'd have no real hope of understanding it even if you did know what the words meant. a science paper isn't going to include an entire field from the ground up just to discuss some small phenomenon.

you do realise that clean coal pumps out slightly more CO2 than 'normal' coal. this is due to the fact that there is no soot(it is turned into CO2) also in removing the impurities you increase the density sso you get more CO2/kg. renewable stuff will reduce the CO2 especially if it is 20% of the energy requirements.

we haven't sampled the core as klay said so we can't give very accurate results but what we can do is run tests using various alloys to see which have similar characteristics to what we can tell about the core. iron and nickel seems to fit very very well and we can make reasonable estimates of the ratio.

the umbra is at a lower temperature because it is the volume that is in total shadow. you cannot see the sun at all from the umbra(maybe a faint ring like during a total eclipse(that is actually you in the umbra). this means you do not have a lot of radiation hitting you(mostly thermal IR from the planet whos umbra you are in) where as further out you can be bathed in the full force of the suns glow. basically, the guy is trying to argue that it should be hotter in shadows. seeing as people seek out shadows to keep cool even here on the surface of the earth i think we can quite clearly say that he is talking rubbish.

yes, this is the speculation section but as this is a science forum we tend to put speculation through a bit of rigor as speculation doesn't mean 'pull anything out your ass and its fine by us'.

if they are crackpot(which they are) then they have absolutely no scientific value whatsoever. no potential except maybe as a plot device in a science fiction story.

stuff grows in warm humid environments which are incidentally found in cooling towers. this can range from the nuisance problems like algae and scaling to biohazards like legionaires disease. it is best to prevent these forming hence the cooling water needs a treatment(anti bacterial and such). as it is also exposed to the atmosphere you are limited on what it can contain(no volatile toxins or carcinogens.)

i think he is talking about making the mold rather than casting at this stage.

well, we can predict the movement of the planets. so you could compensate for that. and if your machine can't teleport as well as travel through time then you could always go forward or back to a time when the earth is in the same position.

thats the definition now, thats not the definition then however.

perhaps you need a few more posts before it will let you create a new group. to make sure your not just going to be here far a few days then abandon the site.

well, the AI could hire some human employees until it has developed robots to replace them.
