So in other words, "a little bit of knowledge is a dangerous thing".
I'm on the fence as to whether or not I agree with you (probably a good thing I don't have mod points right now).
I have been in situations where I have had people say exactly that to me and it is interesting to see the results when you say - "Wow, that's great, please show me." The responses are generally: - 80%, "I'm paying you to do the work and I'm too busy". - 15%, go off and I never hear from them again. - 5%, actually follow through, fail and see the complexity of what is actually being done (this is the best case) - 0.00001%, can actually do it and produce something meaningful. Note this number is my guess as I've never seen it happen.
A "Failure" means loss of the mission. This is an unsuccessful test and is part of the process to ensure the hardware will work with a high degree of confidence so that the mission won't "fail" in its actual landing on the moon.
It should be obvious to anyone with an advanced degree in polygonal quantum mechanics that you can encode information "in the polarization of photons, either horizontal or vertical" and using a Chinese group that began by "creating a single photon that is in a superposition of both horizontal and vertical polarization states. They then convert this single photon into a pair of lower energy photons that are entangled, a process called parametric down conversion. Both of these photons are also in a superposition of polarization states. The router works by using the polarization of one of these photons as the control signal to determine the route of the other, the data signal. The device is simple, little more than a collection of half mirrors for guiding photons and waveplates for rotating their polarization."
Can anybody explain this using something simple, like stuffed bunnies?
The article isn't very helpful and the paper is only available for sale.
In the article it states that Bessel beams are unlike laser beams which "diffract or spread out as they propagate". I know laser beams diffract but I didn't think they spread out (and that was the whole point of them).
Can anybody explain exactly what's going on here and why are the Bessel beams imparting force/energy on the objects toward the beam source?
If the company's employees aren't familiar with the Ap (which seems strange as it is something they are all getting at least some of their salary on) shouldn't this be indication one for the marketeers that it isn't very good? Maybe it's for an obscure market or target customer, but I would still think that people had opinions on it if it was useful in any way.
When I think back to the various companies at which I have worked, *everybody* had an opinion of the company's products and generally used them.
If the majority of employees have no experience with it, I would think the most positive action the company could take would be to fire the Ap's product manager because if the Ap can't generate any interest in the company, then clearly it's NFG.
I would argue that Encarta, rather than supplanting encylopedia's in people's houses showed how unnecessary they are (which was confirmed by Wikipedia).
I confess to buying a couple of copies of Encarta, looking through them and seeing that they were okay - not as good as a set of Encyclopedia Britannica but you could toodle around and look up stuff. But, I was always disappointed in Encarta's depth of information as well as the limited pictures and videos (which were why you were supposed to buy the darn thing in the first place). So, it fell into disuse pretty quickly and the kids used the library for their projects (which is arguably where they should have been doing it in the first place). People got out of the habit of looking to an encyclopedia in the home.
Then along came Wikipedia which really fulfills the promise of a computer based encylopedia with links to images, videos, references you could cite/confirm, etc. which reduced an encyclopedia's usefulness to just being raw materials for quirky leather bound furniture.

Interesting to see the number of posts saying that this is absolutely not possible - reading through the article, it seems possible and maybe there is enough here to study the phenomena enough to warrant more investigations.
The LED seems to be emitting 69 picowatts (pico = 10^-12) when only 30 picowatts of electricity is being pumped in with a measurable decrease in the temperature of the LED. This implies that the LED is acting as a heat pump, converting heat energy into light. If you've ever seen a Peltier cooler in action (or worked through the operation), it seems like to me this is possible.
Note that the power level this phenomenon is observed at is extremely low - the result is maybe good enough for cooling a few molecules of beer - but I think there is something here that should be investigated to see if any usable applications could come out of it.
Thanx to everybody that replied - I realize that the authors and suggested books are well recognized.
But, I should have noted that they are books that a younger reader (for lack of a better term) will probably have not read, even though they are listed.

The most interesting aspect of the article was reading that Qualcomm regularly invests in technology that may not pay back for 10 years.

How is reporting on an eBay sale (for the second time in what two, three days) "news" of any kind, much less for nerds?
Now that it's happened twice, I wonder if /. is hurting so bad that they must resort to advertising stuff their putting on eBay.
What's next, IBM is in trouble because you can find PCjrs on Craigslist for under $1.00?
C'mon guys, pull it together,

This is an eBay sale of a discontinued netbook.
As somebody pointed out, if you wanted a $50 netbook, they can look on Craigslist or eBay themselves.

Skipping over the editorializing in the summary, I would like to point out that the Military using Hollywood for promotion is not a recent occurence.
It should be noted that Abbot and Costello's "Buck Privates" was used to help spur enlistment.
As was "The Green Berets".
As was "Top Gun".
As was a number of other films (these three jump out at me as being some of the best examples).

Actually, the Government had just about nothing to do with the Space Shuttle code.
The group that did it was founded by IBM and has been passed around to a number of other vendors (I believe they have ended up at LockMart).
