i've seen badly made thermite shoot gobs of molten iron 10m or so. it can be extremely dangerous as those will burn through you. there is also the danger of setting fire to everything near it. besides, thermite is really boring anyway. it doesn't actually do anything interesting. i'm currently into the silicon analogues of various hydrocarbons. i've managed to produce and contain silane and possibly disilane though not in large enough quantities to be sure of. Sulphur hexa fluoride is another good one to make. can make your voice really deep if you inhale some of it(it is inert in the body, watch out as it displaces oxygen so take a few deep breaths between inhalations.)

the fact he doesn't understand the principles of electrolysis suggests to me he is not at the level where it would be a good desicion to make thermite.

you have bare copper in the electrolyte don't you?

enzymes are biological catalysts yes. as such, they are extremely sensitive to conditions such as temperature, acidity, electric currents, solute content, and well, a lot of things ordinary catalysts like platinum can ignore. heck, enzymes can be destroyed by mechanical actions like stirring. in other words, for a chemical process like this you'll want an inorganic catalyst. platinum is used though other platinum group elements(gold, osmium, iridium, etc.) can be used.

i don't see anything with points in space expanding faster than the speed of light. i'm not an expert on it so it is only opinion. i'm sure that some cosmologist somewhere some when will perform experiments to prove it or disprove it if it hasn't already been done.

It could be considered infinite in volume and matter but finite in time. also, it doesn't have to be infinite in volume at any one time to be consdered infinite in volume. it could be like Hilberts Paradox of the Grand Hotel if the radius of the universe is expanding faster than the speed of light. though if we find a way to travel or communicate faster than the speed of expansion then this would be null and void and we would have to consider it finite.

that 99.006% of the dat discarded is usually noise, or not the phenomenon you are trying to examine. in particle collisions there are a myriad of particles forming an decaying. if you are looking for a certain type of event within the experiment and know at least most of the interactions occuring then you can write a program to discard the known interactions to find the one your looking for. some of the data that is analysed but not used might have been detected on a wierd angle, might nopt have the necessary resolution(or whatever) to form meaningful results. if you want to analyse the rare red balls that are found in a sea of green balls(which have been well studied already) you don't go analysing ALL of the sea. you just select the red balls and analyse those. or another analytical method where most of the data is discarded automatically, if you want to analyse the isotopes of argon in the atmosphere you'll take a sample of air and run it through a mass spectrometer without separating anything. the peaks for oxygen, nitrogen, CO2 etc etc. will be discarded as they have no bearing on what you are trying to find. you will only take peaks corresponding the the argon isotopes. it would be silly to analyse the isotopes of the other elements there if you are only interested in the argon. i recommend elas takes an introductory science course with some data analysing aspect and he'll see why some data is discarded.

its only about 500MJ per strike. not worth it. and considering the intermittent nature of lightning and the sparseness of it it would be impractical in not cost effective.

a tiny lightning bolt(tinier than you would see in nature) is going to be on the order of 1 MV (1000000V) a big one could conceivably reach a few giga volts(1000000000 V) really big ones could maybe reach 10GV. 10000V is below the static shocks you get from a TV. you need about 3MV for every meter. so yours is about 3.3 mm real powerful that. i've had 10mm off my tv screen.

no it would not be just as accurate. thats like saying a sand glass works on the principle that emptiness falls up. gas pressure works on things bashing into each other this means that only high pressure can exhert a force.

no, the low pressure doesn't draw it up, the high pressure below pushes it up.

its more or less homogenous. there is little variation in ooxygen content through out the troposphere. volcanoes and other major anomalies do exist though.

well, start off by showing you know which substance gets removed by which process. if you know how the process works then it will be easy to figure out the arrangement. we won't just give a straight answer for homework but we will get you to do it. and make you get it right.

learn them by groups. it makes it so much easier. for instance, on monday you could try and remember group 1, tuesday group 2 and so on in a cycle till you don't need to look at the table anymore. of course, anyone working in the field of chemistry is going to have at least 5 handy at all times anyway. so technically its not necessary even though if you just use it often enough you'll pick it up. i never sat down and memorized it but i can tell you where an element is on it without looking it up.

bacteria get their energy from food/sunlight/whereever the point is they have an energy source. it is an open system. remove the energy source the bacteria will either go into stasis or die.

well, the new processor will probably clock back with the slower bus speed. check the BIOS and see if there is options to increase core voltage and bus speed. if there isn't just sell it with the 450MHz processor. there'll be a geek out there that'll want it.

yeah, you won't be able to run at 1GHz with that hardware. and i think, considering the age of that hardware, you might be cheaper(and end up with a more powerful system) by just getting a second hand computer than trying to pry one of those processors off a hardware nerd.

i think i have that episode on DVD somewhere. i'll get back to you with the name if i can find it.

most vehicles on the road today are chemical powered. only the solar ones aren't.

some kevlar put in the mix wouldn't go amiss either. that stuffs hard to cut. hence its application in stab and bullet proof vests

don't use activeX? most people have it switched off for security reasons.

that would produce elemental hydrogen but not elemental chlorine. you'd get managanese tetrachloride and hydrogen gas. EDIT: actually, are you talking about Weldon process? if you do then you are missing some reactants.

i will be watching

yep, some people have the ability to smell cyanide. not sure if i have it as i've never been tempted to have a whiff of cyanide before. might try it sometime though just to see.

an online translator from 'norman albers' to english would be good.
