Well, I guess that could make a spambot the first AI then - given that it's build to make people do things. Given the complexity of the spam/antispam race and the size of botnets it even starts to seem pseudoplausible. It would screw up the net though, and some of us might get some sun...
We found that Europeans are much less price sensitive and much more willing to be early adopters
Maybe the Americans using a piece of software have lower wage and/or prestige in the company than the corresponding Europeans? In that case I guess the European companies would be willing to spend more on the software, which would eventually reflect in the prices.
BTW, for those of you who hate the Maths package available in Microsoft Office, I would recommend Texpoint. That lets you edit your formulas in Latex inside powerpoint, and creates an image (png IIRC)
If you don't need to do it from inside Powerpoint, you can try laeqed, a small cross-platform java program that converts LaTeX formulas to.png. It even saves the latex code in the png comment, so you don't need to have to separate files. I've had good use of it when doing posters. Oh, and it's GPLed:-)
Yes, this heat can be used for things, but its tricky to find a customer for that much heat all of the time.
In Denmark, 60% of housing is connected to district heating. 95% of that heat is "waste" from power plants. If you have cities of more than a few thousand people in temperate/cold areas it's a viable strategy.
Because if you actually studied Economics instead of minority languages, you would understand that Russia is already overspending on its social programmes. Giving money to the poor is the best way to fuel the inflation.
If they can really build spacecraft to bring back frigging soil samples from a martian moon for only 60 MBucks, wouldn't economy rather dictate that other nations out-sourced their development to Russia? It might actually help their economy and total global friendship and all that. And the budget of {NA|E}SA.
Nope, core is ferromagnetic. Ferromagnetic materials are named after "Ferrum" (iron), because they are alike in that when you put them in a strong magnetic field they'll become little magnets and stay that way, even when the field is gone. Incidentally core was made of ferrite (iron oxide).
Ferroelectric is named after ferromagnetic, because it's the same, only with electric polarization: If you put a ferroelectric in a strong electric field it will become positively charged on one end, and negatively on the other, and then stay that way even if the field is removed. Some crystals (Barium titanate and others) can do that by all the molecules in the array distorting, so the positive and negative ions move a little in opposite directions.
Now, if you put a little piece of crystal between two leads you can polarize it that way, and if you put the gate of a transistor near one end, it will open or close depending on the charge there. Now you can write the bit by choosing the polarity of the two leads, and read it by measuring the current through the transistor.
First, the real links. I don't know why the blogger didnt't include them, and I don't think this should have gone on the front page without them. Oh well, there's always the comments...
This is NOT flash ram, it's ferroelectric RAM. This doesn't matter much to the consumer who can use it much the same way, but it's a different principle. Apparently they've (semi-)tested 100 million r/w cycles, and expect that it can hold data for 10 years (extrapolated from some curve). Besides, it uses a lower voltage than flash, and they expect it to scale down further. Nice. It even looks like it might work. SSDs for teh win:-)
As far as physics goes there's only sense in learning languages other than English (and maybe Russian, French or Japanese for a few obscure articles) if you're interested in history. The final polished version of a theory is easier to get from textbooks.
Correlation does not equal causation! And if Union is so great, can you tell me what happened in the US 1861-65? Not to mention the Soviet breakup.
It's a know fact that democratic countries fight each other very rarely or not at all. Now given that, how hard is it to keep the peace in a club that only allows already democratic members?
Or perphaps Europe was just scared shitless by the Soviets?
Yeah, doubling in 10 years. The price has doubled in 1 year in the US. How would you feel if it went up to 3.24 euros/litre over the course of the next few months? Well, if everyone in Europe is just so happy, then what's up with the spanish truckers?
That's what you have to ask yourself everytime you read something like this. Who is interested in playing up the rogue nuclear threat at the moment? The US of course, to put pressure on Iran (through Europe etc.)
Could you show your math? After all, these guys do, and they get that at 8% efficiency, half of NM would cover all US energy consumption. I don't know if that includes transport and conversion losses, though.
This thing is probably Very Nice (if it wasn't slashdotted) but I'd want to pass the raw output to my own data analysis algorithms. Why should it just be a gaming device? I guess it can double as a sleep rythm detector, or maybe I can tune it to work with me, instead of the other way around.
Legalize the transmission and possession of child porn I don't think anyone who'd been abused would want the pictures freely available. In this case it's close to certain that the guardian of the child (or the child when it comes of age) would want an injunction on the material. Having it illegal achieves the same effect, but with much less bureaucracy. Besides, there'd always be economic demand for "fresh" material, I guess.
Criminal code 235 (my danish-english legalese translation is shaky):
"...Who possesses or for money acquires adulterous photos or film, other adulterous visual reproductions or similar of persons under 18 is punished by fine or prison up to 1 year." As far as I've understood the law is only thought to apply if the material is graphic enough to be confused with reality. I think there's a proposed EU directive on this. I'm ashamed of my country.
With nuclear, we have Yucca Mountain. As far as I have understood, the waste takes about 300 years to decay to the level of radioactivity present in the mined material. (Can anyone corroborate this figure??). In that case our storage plans need only extend for 300 years, and after that the same precautions are needed as for unworked uranium mines. (Hint: none).
In fact, nuclear plants have somewhat the same problem as wind power: You can't regulate production as you'd like. (Nuclear plants generally operate a lot better keeping a stable base load).
My department develops fuel cells, and we recently had a professor from the Sustainable Energy Planning Group give a talk on how to move away from fossil fuels. The main part of the solution is combined heat and power plants (CHP). In Denmark such plants already supply the heating for even small towns. The trick is that these can adjust towards producing either heat or electricity, and heat is way easier to store. (On the Nordic electricity market electricity prices hit zero once or twice a year due to abundant wind power, so any storage tech will earn money, though of course capital prices have to be offset). His scenario for Denmark on sustainable energy included greatly expanded heat storage. He also noted that while Denmark needs heating for housing around two thirds of the year, CHP is also relevant in a place like Thailand, where the heat is used in industrial processes.
I don't know if nuclear power is suited for CHP, in that case it would make a cheap, efficient and carbon neutral complement to wind energy.
Yeah, I've got to second that. There's lots of good stuff there, and I've spent too much money on their e-books. Apart from that they're just so bloody sensible.
No, I've never heard of spintrons. I think it's just a construction to sound like electronics while implying that it's about spin. I don't know who invented the term, but I don't mind it - it's relatively descriptive after all, and it's used in a number of scientific articles. The one problem might be that it can become a bit over-hyped, but in general too few people know about it for that to be a problem.

The President's actual budget for 2007 totals $2.8 trillion [...] The total requested military budget of the United States for 2007 was $699 billion.
Social security is the biggest domestic at 586G$, unemployment/welfare is 294 G$. Your point still stands, though.
"The courts might not work anymore, but as long as everyone is videotaping everyone else, justice will be served."
Very funny. But who was videotaping when it was decided how to award the no-bid contracts for the Iraq war? We're catching the small fish here...

Yes! And open source it! My DNA is GPL!

Bohr was Danish. His correspondence is in Danish, English, German, French and Swedish.

I think you should reconsider how IMing is being used to communicate with the locals. No reason to be Luddite here ;-)
I always think of room temperature as 25 meV...
That's what you have to ask yourself everytime you read something like this. Who is interested in playing up the rogue nuclear threat at the moment? The US of course, to put pressure on Iran (through Europe etc.)
Not in Denmark - here people usually use km/l. YMMV (at least the unit!)
