Ah, i have to disagree. Having spent my early youth with chemistry mostly, electrolysis was my neverending source for fun things like hydrogen, oxygen and chlorine. I started with batteries which indeed produce no noticable heat. For economic reasons i soon switched to a different setup, connecting the transformer for my model railway with a crude rectifier made from scrap parts from a tv, thus being able to use the power outlet in a safe manner. To my disappointment, I couldn't use maximal setting on the transformer, or the water would start heating up to the boiling point. That is to say, any industrial sized form of electrolysis produces can produce a lot of heat.
Infact, the usual process of producing Aluminium is electrolysis of certain Aluminium salts, as you mentioned. The salt has to be molten first in order to be conductive at all, but after that the heat from electrolysis in sufficient to keep it molten and melt the salt that is added to sustain the process (at several hundered degrees Celsius).
GP:... and which isn't all that much slower due to the Turbocache architecture...
P:...the system is a lot slower...
mmmkay that didn't make much sense... was your point that nvidia is lying about the TurboCache performance ? Did you try to debunk GP's quoted assumption?
Doesnt really matter, since even if it is true, we could simply build breeder type reactors, where you generate more fissionable material than you use.
And of course the foundation of the EU was laid by a Franco-German pact to create a counter-weight to the US, decades before Dubya ever entered office.
No. After WWII there where several efforts to bring peace to Europe by having them build unions. The OEEC was actually a necessity for the Marshall Plan, which later evolved into a free trade union. So the US itself layed part of the foundation of the EU. A unified Europe was also in the interested of the US as a counterpart for Russia. Seriously, the founding of the EU has little or nothing to do with "counter-weighing the US". The European nations mostly realized that pillaging each other every other decade is not a good thing. They, at least Germany and France, had to fear each other far more than some far away, barely post-isolationist nation that one day might aspire to become a super-power.
Ah, there was a discussion about this in a recent thread... can't remember which though. The electrons cannot travel with the speed of light because they have mass. But they don't need travel much anyway, because the information is transmitted via the electrostatic force which can be explained as the exchange of virtual (light-speed fast) photons. So the first electron in the wire gets pushed a bit and in turn pushes the second electron in the wire and so forth, much like when you push one end of a stick and automagically the other end moves too. In both cases the effect is not light-speedy but speedy nonetheless.
Actually this one would decrease the heat generated, as SiC is a better conductor, especially at higher frequencies. The nature article is a bit more interesting if you sometimes like to RT(F)A.
But then again the SiC chips will be pushed to their limit eventually, where they will be glowing red or something.
Actually they should interact both des- and constructively with eachother, and on average not at all, otherwise you would have the opposite of a laser: A light source that is dark because all rays annihilate eachother.
I cant really remember the PIN for my bank account, but when i'm standing in front of the cash automat i remember the moves i have to do with my fingers without problem. If i wanted to remember the PIN as a number i can close my eyes and pretend to type it though, so there is a way for me to know it consciously.
It is true that "chen" is a standard diminutive appendix, and all diminutives are neuter. (as a side note: Maedchen stems from Magd i think, (the "g" was lost over time and the Umlaut comes naturally with the diminutive) but only Maedchen survived the times as Magd is used only very rarely).
But "Sonne" is not a diminutive so it should be the gender of the word, I have to admit though that i am not sure what you mean with the gender of the thing to which the word refers.
Definitely interesting and disenchanting. Are you sure it's not the leaked windows source?;)
Unfortunately I don't have 2.6 kernel available to check but here's a 2.4.22 instead:
Well i am sure he didn't say "there is no place for anything like a GOTO". It is quite practical when you ask for directions on the street.
Now in programming languages the use of GOTO usually means that the programmer didn't really think about reasonable controlling structures and it tends to generate nondeterministic-for-practical-purposes behaviour. And finally, having GOTO in html surely is beyond the scope of a markup(!=programming)language. It is a skript that is being parsed once, from top to bottom. Having the capability to implement its own dynamic generation is bloat when there are already dozens of ways to generate html dynamically.
Thanks for the link, that map is really interesting. I would have never guessed that the ISS was so close. The huge areas of nothingness are a bit dissapointing but I guess space is just that mostly.
At
a distance of over 8 billion miles, Sedna is so far away it is reduced
to one picture element (pixel) in the image taken in high-resolution
mode with Hubble's Advanced Camera for Surveys. This surprised me a lot. Hubble can take pretty (for me as a non-astronomer) pictures of objects far away and in the past (wasn't only recently something so old that it is almost the beginning of the universe?), and yet it can't take a picture of something within our system larger than a pixel... Anyone with some knowledge care to elaborate on that?
a) no more html email. Period. There's no reason for it other than making email look pretty. I've never run into a situtation where an informational email couldn't live without html.
Maybe you didn't have that that problem and neither do I. But i know a lot of less technically inclined people, who would send an email simply because it is pretty (say, because their new email program has these pretty templates with pictures of hawaii as a background.). Same goes for attachments. Email isn't only used for short, important messages. People use it to socialize, and as such they send stuff they think is funny, pretty or shiny.
I think viruses over email will stop as soon as sexually transmitted diseases will stop because people stopped to have recreational, unprotected sex.
The car looks somewhat like a mercedes A-class/smart hybrid. It looks like a perfectly normal city-size car to me (albeit not the prettiest one), but I guess that depends on where you live and what you are used to.
The whole biometrics discussion only became more than a stupid idea after the 9th September. I guess everyone knows by now that the terrorists lived and studied in Germany before thay attacked the world trade center (or some of them, i forgot). But the point is, that they haven't shown any suspicious behaviour before their attack.
So most sane people have argued that the problem wasn't identifying the terrorists, for which this would be a possible solution. The problem is to know who is a terrorist, criminal etc while their actions still lie in the future. Obviuosly this problem is not solved at all.
The government is simply using this as a placebo to soothe the fear of terrorism in the gullible general public and as a neat side effect they increase their control over people. imho of course
doh..., i forgot
so suppose you have 10mol/l hydrochloric acid, HCl. It will be almost comletely dissociated, hence you have a H+ concentration of 10mol/l => -log(10) = -1. so the acid has a pH of -1.
close....
pH = -log([H+]), where [H+] is a usual way to denote the Proton/Hydrogen cation concentration. So for pH 7 we have the natural concentration of 10e-7 mol/l of H+. The pH may however be larger than 14 for very strong bases and smaller than 0 for strong acids. For the latter case, it simply means that [H+]>1 mol/l. Concentrated hydrochloric acid has a negative pH e.g.
Also, Hydronium ions are hydratized H+, H30+, while OH- are called hydroxide ions.
it distorts the space-time-continuum. look at second picture. why can you see the screen both in the actual laptop and in the reflection on the table ???
no, no. Of course white phosphorous is even more reactive and may even ignite itself when in contact with oxygen. But red phsphorous burns pretty good, too. makes a lot of smoke as well (good for smoke bombs, the smoke forms phosphoric acid thogether with the air humidity though) and together with potassium chlorate (KCl03) it makes nice explosions.

Not invaded Kuwait
Not swiped $20 Billion
Not spent his cash on the Military
Complied with UN orders
Had the best interests of his people in mind when he made decisions
Complied with international pressure
Not been a crook i would say then he would have been a better leader than GWB

red phoshorous as a flame retardend??? it always burned quite nicely when I used to play with it...
