I though about it a long time ago because I know we are using the same kind of technology in the airports.
Near the landing strips you can sometimes find some "sound reflectors" which just reflect the sound wave they receive from the planes. The sound is then cancelled by itself.
I saw it once in an airport in France and it works really well and costs next to nothing. AFAIK there's no sound wave modification in that system but I'm not sure (maybe the surface of the reflectors is made in a certain shape to change the sound wave a little).
But in this case it's different because the "box" must produce the counter sound wave. It's not just reflection, there is sound generation here. It means that the microphone and the speakers must be very precise or you just end up with more sound.
But if this guy can do it with 20 bucks it means that it's much easier than I though.
Yes it does. We tried to do everything to prevent that law from being voted.
We wrote and signed petitions but nothing worked, we lost and now this law is very effective.
It's very bad for all the computer industry in France.
But I've heard that at least 25 other countries in the World do the same (including Canada AFAIK). So I guess it's gonna be everywhere in one form or another soon.
First MS is not the first company to be condamned by a Europe court. You want to sell things in Europe? So you have to follow Europe's rules wether you are American or European. I have countless examples. The biggest difference here is that unlike in America, MS is not allowed to inject millions of dollars in Europeans governments. Lobbies can't buy European politics. Sorry, try again.
Yes, the Evil Europe is subsidizing the Evil Airbus and the Good US is trying to compete with the Good Boeing.
Wake up, US and Europe both agreed to a treatie in 1992 which regulates government funding in companies.
Both are allowed to subsidizing up to 33% of the investments in their companies, in direct and indirect fundings.
Indirect fundings happen when the US government gives billions to Boeing for designing new military planes and when Boeing uses this research to create civilian airplanes. Airbus suffered from that for years.
The difference here is that the 1992 treatie implies the refunding of all direct investments but not indirect investments. So Airbus has 17 years to give the government back it's money where Boeing will never have to give to R&D money back to the US government.
The surrounding fluid within which the atoms being forced together is cold.
The fluid is cold of course, but the middle of the bubble is very hot due to compression, it's in the article. And the reaction takes place in this little area (middle of the bubble) that *is* very hot.
The palladium rods which "contained" and "violently forced together" the atoms in "cold fusion" was cold.
Yes but here the atoms themselves were hot, not the surrounding material. That's a huge difference because in the other experiment that's the surrounding material that is hot.
It's not cold fusion, it's called sonofusion. It's in the article too.
... they squeezed tiny gas bubbles in the liquid so quickly and violently that temperatures reached millions of degrees and some of the hydrogen atoms in the solvent molecules fused, producing a flash of light and energy.
Actually WYSIWYG is maybe the worst thing that ever happened to word processors.
Because of that 'feature' nobody knows how to use a Word processor nowadays. I've seen so many people putting in spaces to get some tabulations and stuff like that...
It's amazing, it reminds me of the Manhattan Project.
At the time the scientists were looking to get enough Uranium (238) and Plutonium to build the bomb. Everything else around was ready but they were producing only grams of the required materials a week.
In only 2 years they improved the production quality and quantity dramatically to levels they didn't even dreamed of before.
That's when they understood that what they though was granted long before (the 'rest' of the engineering needed for the bomb) was the actual hardest part to 'build'.
Maybe this will happen to the space elevator with the nanotubes.
Getting 100 GPa for carbon nanotubes composite is one thing. Getting 100 GPa on a 100000 kilometers carbon nanotube composite is another.
I'm more interested in the length of the nanotubes than in their strengh since increasing the strengh is quite easy (basically all we need is to increase the fraction of carbon nanotubes in the composite) compared to increasing the length of the composite.
We're the richest, most powerful, most prosperous country in the history of mankind. You can just add this to the list that the US leads in. Leading in spam is a small price to pay for this.
Which is because you are financed by all the others countries in the World. Do you know what the national debt means? It means you bought an amount of 7 000 billions of goods to other countries without paying them. You owe that money to the rest of the World and it's the biggest debt the world has ever seen.
Easy to be World's first when you can print as many Dollar bills as you want without creating domestic inflation.
Read the link in my sig to understand that and to see what will happen when the world decides to stop using only the Dollar as a reserve currency.

Ok listen everybody. Let's try to go on the website one by one.
Scenarios to be considered include the threat of a 360-foot-wide asteroid destined to hit Europe, a comet aimed at the Mississippi Valley and a small asteroid headed for the Pacific Ocean 200 miles off the California coast.
No scenario about Asia and Africa? Weird, last time I checked most of the population of the World was in Asia. It would make sense to at least think about it...
If you want to see this effect try this (a teacher told me about that 10 years ago): on a day without wind go in a light boat with something like 300 pounds of rocks. Go in the middle of a lake and launch all the rocks in the same direction as far as possible. After a while you'll notice that the boat is moving slowly in the opposite direction (depending on the weight and speed of the launches).
Nice trick that makes lot of sense in vaccum, with hundreds of 'rock launchers' and continous launches over a very long time.
As we say in French, "toute action entraine une reaction".

Of course he is much smarter than I am, otherwise I wouldn't be posting on slashdot.

Ok I was waiting for this one. Not surprising.

Because you really think that NASA will go to the moon or Mars like Bush said?
Because you really think the Congress will let him do that with a half trillion deficit?
Well, it's election year guys. NASA will go nowhere, the Congress will never vote for it and one year from now we won't even talk about it.
No it's not.

It's not cold fusion, it's called sonofusion. It's in the article too.
No, not the same principle, cold fusion means fusion reactions *without* the need for a very high temperature.
Here we clearly have very high temperatures. Enough to create hot fusion reactions, the same we can produce in tokamaks and H bombs.
Actually after a while the walls of a tokamak have to be changed because neutrons makes them radioactive on the long run.
So yes this would produce radioactive material too, but a material less nasty and lesser material than a fission reaction.
... they squeezed tiny gas bubbles in the liquid so quickly and violently that temperatures reached millions of degrees and some of the hydrogen atoms in the solvent molecules fused, producing a flash of light and energy.
Please note that this is *NOT* cold fusion.

From this page:
Pixels are unique prototypes, and are not for sale. I am sorry for all those who would like to buy one.
Too bad I can't buy one... Do you know if it's possible to buy an equivalent or to build my own? Is it a hard work?
Looking at the pictures it doesn't seem hard to do...
... although the amount of exports to China are so small we really could do without them.
I'm not sure guy, you already have a huge trade deficit and it wouldn't be a good idea to make it bigger. Follow the link in my sig to understand why.
And that's the solution, Japan did the same with car factories in the US.
Microsoft will do it because China will soon become the biggest market of the 21th century.

How do you do that? You catch them with a giant Swiffer mop?

It seems this plane needs a very light but very strong structure, could nanotubes be helpful for that kind of design?

Of course, they spent SO MUCH MONEY in promoting their 'Intel Inside' logo and music on TV...
It shouldn't be associated with anyhting else.

When the powder exploses it pushes the bullet forward but the explosion also pushes in the opposite direction.
Yes that's in part why you have a strong kick backward with a gun when you fire a bullet.
