Err, not to be picky or something - it IS the accretion disk.. Very hot plasma around the black hole (but Above horison of course - in fact the closest part of the disk is (should be) about three times the radius of the horizon - depending on the rotation of the black hole)
One number that is very surprising - the matter falling into black hole can convert almost half of its rest mass into energy to radiate! Much more effective than fusion can be.
There is nothing wrong with "chalking it up" to the dark matter. Accepting possibility of MACHO of minimal sypersymmetric neutralinos (I have done simulation on possibilities to detect them, for my thesis - it looks like we will have to wait a bit:) - have less impact on current theories than questioning gravity. And the rule of thumb is - first think about a less radical proposition: question foundations of the theory only when nothing else works. It may sound not very "imaginative" but it is the best approach found so far. This research is hard enough without having to rethink all the basis every week.
Dark matter is a bit more local observation - by looking at the rotation speed and mass distribution of OUR OWN galaxy, we can conclude that most of its mass is not visible as stars. So it is not directly related to observing far away galaxies. - But it affects our estimate of the average density of matter in the universe.
These new galaxies were not visible because x-rays dissipate less over distance. New gamma ray observatory (GLAST) will see even more distant objects.
And not some other beer? Viscosity maybe the key, but I just poured myself a nice cold glass of my favorite lager - even less liquid then the Guiness, and the bubles do not appear to sink near the wall.. Hm.
Maybe my lager is transparent, so I do not notice smaller bubbles near the wall.. Will get my magnifying glass..
Nope. Strange.
Maybe it so cold and dtrong, taht it does not have enough bubbles and convection...
Judging from the number and content of the comments in Russian, I will bet a lot of that credit card holders will be surprised to see their bills soon. Most shops in Russia do not do a good job verifying cards, and it would be kinda hard to get to them to reimburse the charges. Oh, well, not that I will cry for US credit card companies..
..on what you mean by outperform. For my analysis code flexibility of the software solution vastly outperforms lower latency of a possible hardware implementation. In the case of modems (of which I have no knowledge) adaptible code maybe (possibly) be better than rigid hardware solution.. Though I would guess that it is done anyway - just by a chip on the modem board - not by central CPU - that's where Winmodems suck, not because pure hardware/software difference..
No, I am not wrong. Do not you see the difference between discovering "a new and useful blah. blah, blah" and a scientific discovery? The difference being that scientific fact would exist independently from the civilization (let's forget philosophy for now). While discovery requires a man to be acting. If you make some more searches you would find that mathematical formulas, chemical compounds (though you can patent the process of making said compound), physical laws etc. can not be patented. - Altough with the current system I would not be surprized if something like that happened. Software algorithms happened to be patentable as they were originally very related to the ahrdware implementations. Nowdays, it is more of a pure science, and should be treated accordingly. As for protection of independent software developers, I would think they will be much better off not worrying about hundreds of patents big corporations have to crush them.
Patents can not be granted for discovery - only for non-obvious invention. Look it up.
There was no discovery in noticing a sticking plant. It was known. The usage of this knowledge that was inventive. With wavelet data compression, there was nothing inventive - only careful implementation of a scientific knowledge. Copyright protects implementations - not patents.
Additional comment - sure, making a useful algorithm out of a theory deserves to be rewarded. For this copyright protection, trade secrets, NDA's and so on is more than enough.
Look at wavelet or fractal image compression. I would hardly call those "obvious."
Yes it is not obvious. But it was discovered. You can not grant patents for SCIENTIFIC DISCOVERY.
Meyer, Gabor, Daubechies, Donoho and other scientists that made this methods possible do not own any patents on these discoveries. Why should some jerk be able to rip off their hard work, package it nicely and get a monopoly on a useful method? Greatly delaying its widespread use?
Patents are useful - they force to disclose trade sectrets - in exchange for monopoly of course. Nothing that can be discovered may be a trade secret for long. Thus there is no use for this trade off. Software patents should be banned for good.
Yeah, right. And it was not German engineers who designed all US ballistic missles.
Stole nuclear weapons? In my physics lab right now among all graduate and post-doctoral RAs there are two Russians, on Brasilian, one Dutch, one Spaniard, one Chinese, one Japanese and ONE (ONE) American student. It's a government lab. And that's rather typical.
Who stole what? My brains have been bought, that's for sure (not that I complain), but cut the arrogant shit about stealing...
Yeah, maybe I am not on the cutting edge of feature use.. As I have to reuse old C libraries, nice STL style creeps in slowly. What is a shme IMO. Still, considering multiplatform support of the g++ it kicks commercial butt pretty hard....
Huh? How's then my GCC 2.95 code runs faster then VS6.0 (around 4% faster on PIII, it's a heavy duty simulation library) and support more of all the STL features features I need? Besides being able to compile it for the SPARC and AIX farms with no problems. - Unlike MSVC.
And GNU C++ didn't become a reasonably complete C++ compiler years after good commercial implementations were already out there
That's funny. Taking into account that C++ just became a standard, and I still have to see a compiler that implements all the standard library properly.
IMO GCC C++ is one of the better implementations out there that we got faster than many commercial ones (I used all the current versions of Visual Studio, Borland's stuff, KAI and a bunch others..)

due matter falling into the accretion disk
Err, not to be picky or something - it IS the accretion disk.. Very hot plasma around the black hole (but Above horison of course - in fact the closest part of the disk is (should be) about three times the radius of the horizon - depending on the rotation of the black hole)
One number that is very surprising - the matter falling into black hole can convert almost half of its rest mass into energy to radiate! Much more effective than fusion can be.
...I lost my ability to type and read. And you say question gravity. I will die here then.. Let it be Dark Matter...
I meant MACHOS or neutralinos of course. Theses are very different ideas...

Can these non visible galaxies be counted?
Dark matter is a bit more local observation - by looking at the rotation speed and mass distribution of OUR OWN galaxy, we can conclude that most of its mass is not visible as stars. So it is not directly related to observing far away galaxies. - But it affects our estimate of the average density of matter in the universe.

you are right - but you are not a programmer, i guess :) 800 x 255 = 199K (180K = 184,320)
...you will notice that the cheaper model has more pixels per LCD (180K vs 150K) but states twice lower resolution. Why? Mistake?

Says something about progress of that development.
Why do not they open a start-up, get $1B of IPO money, and actually hire somebody to nake the product.
I am only partially kidding
