objects with the opposite electric charge(like an electron and a proton) attract each other, this force is far stronger than gravity, and gravity on that sort of scale (especially newtonian gravity) is just insignificant.

carbon 3? thats an impossible isotope. what you should have got from that was, 3 carbon atoms and 8 hydrogen atoms.

LASER, not lazer. laser stands for Light Amplification by the Stimulated Emission of Radiation. what you are talking about by having a proton 'bullet' is a plasma weapon. this would be inneffective in an atmosphere beyond a few meters but may have applications in space-to-space weaponry, again it would have limited range. inserting a males genes into the egg can be done. this effectively uses the 'mother' as an incubator massive amounts of information are required for this, and if you have the technology to reconstruct an entire human at the subatomic scale then you are going to be able to give that body life. there's more to it than that, but biologists are still working on an actual answer. actually, this is quite plausible, when someone dies the body is still technically living as the biochemical reactions are still taking place, muscles will still respond to nerve impulse and so on its just that the body is no longer functioning on an electrical level. and it would take something a bit more complex than a jolt from a lightning bolt to set it right. lack of evidence is not evidence of lack. but the curently known laws of physics disallow it for other reasons.

but if its charged then the atoms are going to be in the excited state, which isn't stable, so it would self trigger like in a normal laser.

not really, you could split the column up into more manageable chunks and just pump to top stream from the previous column into the bottom stream of the next. but its still going to be impractical. you would need hundreds of columns and all just for one feed. and your product stream is going to be just a trickle compared to the torrent thats going into feed. not to mention distillation columns are expensive, expensive to build and expensive to run. especially when the relative volatilities are so close. EDIT: whoops, mean to say, bottom stream of the previous into the next column.

isn't that ow the photon multiplier tubes in night vision goggles work? edit: yep http://en.wikipedia.org/wiki/Image_intensifier

why have you used 17.09g as the mass of propane and not 17.60g like the question says? and the errors you are getting look like simple rounding errors, try using more significant figures.

lets see, do climate models make predictions? yes, they predict that the temperature should continue to rise, they also predict by how much it should rise. are these predictions testable? yes, we wait and take temperature measurements. is this science? yes.

the fuel to oxygen ratio is well outside combustion limits it would not ignite.

filtration won't get you anywhere. distillation will only be slightly better, rough back of the envelope calculations tell me that to get a 50% mole fraction of heavy water your going to need a distillation column at least 25km high.

i know the pole isn't at true north now which is why i used the word 'further'. and bt that i meant a far larger drift than the current wander it does.

B&Q(a hardware store for those outside the UK) no idea what the equivalent wattage is but they're pretty bright.

i'm going to go ahead and guess carbon.

i already have some. they look very cool

yes, someone should. seeing as they seem to be part of a 'ZOMG! WE'RE ALL GONNA DIE IN 2012!' group, i don't think they can be used as a reliable source or even a well intentioned source. the pole reversal can be successfully modeled using scientific theories and we have evidence that it has happened lots of times in earths history, even with humans about so we can be sure it isn't going to wipe us out or even detriment us significantly. our technology will be more exposed to solar flares and the like BUT we know it is coming so we can prepare contingency plans and effective shielding. radiation exposure on our person will also increase, but it should be significant enough to kill people by the millions and we definitely won't be getting giant mutated cockroaches as one 'ZOMG MAGNETIC FIELDS ARE GONNA KILL US ALL' person has claimed. they are far more likely to be found under george w bush's bed as thats where i put them. basically, the field reversal is situation normal, just don't trust your compass.

yes, i should probably clarify that i am not saying humans are not a factor in GW just not the biggest... yet. i'm sure a large change in energy influx from the sun would have a much larger and more sudden effect than us doubling or halfing the rate we pump out CO2 and other gases. or if the yellowstone caldera erupts. nature is currently holding the trump cards in GW. economics is almost entirely a human influenced construct. nature can still play a role if it leads to a bad crop or a particularly nasty storm wipes out a large number of oil pumps but humans can have an even greater effect and nothing has to happen bar a few stock brokers panicing and dumping a company like a tonne of bricks with no real cause other than they thought it was probably a good idea. unlike people, the earth does not panic.

lol, none of those are signs of a pole shift. the first signs of a pole shift are a weakening magnetic field with magnetic north straying further from true north which is what we see now. over the next few hundred years the field will continue to weaken before becoming slightly chaotic and the earth having more than two magnetic poles before the field settles down and strengthens again but the other way round. nothing disasterous happens, just compasses point the opposite way.

well, in the economic environment humans play a much larger role than in the climate. the climate obeys the laws of physics and chemistry and human influence plays a small role so can't really cause a sharp, severe disturbance. economics however, is entirely dependant on humans and doesn't really follow all that many rules. and the rules in place can be broken.

So, What exactly is stopping you from leaving the house and going to meet her, or anyone else? it sounds like fear of what your parents will do to stop you. but really what do you have to be afraid of? you are too young for them to evict you from the house legally. sure, they'll probably be mad at you but you'll probably make some friends that will help you deal with it if its a problem for you. and, seeing as they are religious, the excuse, 'i went to meet a friend from sunday school' will probably lessen any anger they do have.

yes, we know all that, what the hell is your point, seriously you are acting as if biologists(specifically biochemists) haven't quite caught onto the fact that, wait for it.... water is involved in biochemistry. seriously, they concentrated on the other stuff because without that water would be bloody useless. what you are doing is the equivalent of looking at a design for an engine, where some mechanical engineer has spent months making detailed calculations on exactly how much fuel it'll need how much airflow will be required, so on, so on and then claiming that he really hasn't understood the importance of the air as it will work differently if you feed it water instead of air. your position makes no sense whatsoever and makes you look quite the fool.

well, the fossil fuels don't need to be entirely depleted, they just need to be low enough so that extraction becomes increasingly expensive. power prices will rise dues to power companies trying to keep themselves afloat(assuming they do not have a nuclear base for which the costs would stay roughly constant because of the relative abundance of fuels.) and yes, nuclear will take time to roll out, but the point is, we can roll out a viable generation of nuclear plants before solar/wind approaches large scale viability.

yes, power storage provides a buffer, but the most you can reasonably expect in the next 25-50 years is perhaps a day of energy storage. now, this is fine if you only have a deficit for a short period of time, but long drawn out deficits are possible. not to mention that due to the variable nature of the energy sources you want to draw from, we will need to build far far more of them than the theoretical minimum. at current even if we use the theoretical minimum we will not recoup the energy required for their construction within the lifetime of the equipment. not to mention the cost. until we can develop a sustainable sustainable energy economy we will need nuclear, especially as oil reserves continue to fall. we NEED nuclear. to say otherwise is to blatantly ignore we have no actually viable alternative at present. please note that i am not saying we will never have a viable alternative just that we do not have one that could be implemented on a global scale before fossil fuels are depleted. And just to make my point on nuclear(fission) perfectly clear, i do think it is a crap solution as fissile materials are also a finite source(and tend to deplete themselves) and is hence not sustainable. BUT it is the best solution we have as the technology and resources to SUCCESSFULLY implement it are available NOW, not later. when the technology to switch to a truely sustainably resource becomes viable then i fully agree we should transition to them, but as it currently stands they are not viable.

mirror matter? never heard of it. what is it supposed to do?

yeah, with the current renewable energy sources they are far too variable to be effectively used, especially for base load applications. lets say the uk switched to a mix of solar and wind power. now, its winter time so solar isn't quite pulling its weight and we have a high pressure system sitting over the country(as happens on occasion) so wind is also not pulling its weight. couple this with the fact that we will not have a substantial base in either coal oil or gas energy production at this stage we're going to be experiencing at the very least, rolling blackouts. if this continues for long enough then important infrastructure will fail, like water treatment plants. if water treatment plants fail then river pollution will go up and bring the dissolved oxygen level down and kill off the british fish farming industry. and thats just one way its a stupid idea to build up reliance on inherently unreliable power sources. we NEED something to provide a solid, never gonna fail base power production day and night. whether its been dark and calm for a night or a year. nuclear is an excellent way to go until we can develop something better.

wait your saying water and acids are tuned to fit the pH scale? wtf? NO! we invented the pH scale to represent the concentration ratio of H+ an OH- ions in solution. and of course if you have a different thing its going to behave differently. time for you to stop talking like you are the omnibrain and actually go take a look at what actually happens.
