A Triple-Standard Disk

It seems like 2 markets were formed when the companies couldn't agree on one HD disk standard. Some of the same companies that couldn't agree are now going to step in with disks that work in both markets. Kind of lame.
I guess what I am saying is that if there was only BluRay, there would be no need for a disk that had BluRay, HDdvd and DVD. Convenient.
If the 30% solution of borohydride (by mass) has the same density as water (which is not true) then you have.30 g of NaBH4 per mL of solution.
Each gram of NaBH4 of has.108 g of hydrogen in it. So you have.032 g of H per mL of solution.
You get 1 *molecule* of H2 from each atom of H in the original compound. So you multiply the mass of by 2. This gives you.064 g of H2 per mL of solution.
The density of liquid H2 is ~0.68, so that is where the magic number of 30% comes from.
The reaction is: NaBH4 + 2 H20 -> NaBO2 + 4 H2
Liquid H2 is not very dense at all. It's density is.068 g/mL (compared to water, which is 1 g/mL). When the borohydride is added to water, you get NaBO2 and 4 H2 molecules.
Just kidding, I guess there aren't that many people who read slashdot.
In unrelated news, who knew that James Baldwin ghost-wrote for Jack London? Google, that's who.

This seems like a warning sign to me. If you don't know how much it's worth and don't see how it can make money, you probably shouldn't spend a billion dollars on it.
there is still plenty of confusion about the fair value of online video companies. This is because the typical metrics for measuring a company appear to have gone out the window--just like they did during the bubble years of the late 1990s.
Nobody knows whether anyone can make money by hosting user-submitted videos. (None of the top standalone companies in the sector has reported profits.)
1) Player Cally starts the EVE Investment Bank in early 2006
2) A lot of drama goes on in the mean time with people sticking up for the EIB and others calling it a scam
3) Cally's owner decides it's been long enough and cleans out the bank, netting around 700bil in ISK and another 100bil in assets
That's really all the high points.
Regardless of the economics (which you discussed quite well, I think), the moon should be very metal-poor if it was formed via collision. The heavier metals "sank" towards the core when the earth was molten. The collision knocked off the top, lighter material, like silica.
The density of the moon is 3.35 g/cm^3 whereas the density of the earth is 5.51 g/cm^3.
It doesn't say in the article, but I wonder if any of the outputs actually work. On my DVR (a Motorola), there is an ethernet jack, SATA port, USB ports and Firewire ports. The only one that works is one of the (two) Firewire ports.
And since acetone is a VOC, when Mohammed walks up to the scanner, the scanner screams bloody murder... which would be fine, except that it also probably screams bloody murder for every woman with a bottle of nail polish remover in her purse. So Mohammed gets told to move along, too.
No, the scanner would say "acetone."
But since hydrogen peroxide isn't an organic compound, Abdul walks up to the scanner and it says "Nothing to see here. Move along."
There is nothing specific to the technique that prevents it from recognizing things that are not organic. This is just a highlighted capability. It is like assuming that Vista doesn't have a calculator because you haven't seen it mentioned in press releases.
Here's a schematic It also says that it can detect compounds in the ppb levels out of breath (in real time). What I am wondering is how large/portable this machine is. Could a baggage handler walk around with it and wand things, or would you need to put all the bags through the machine on a conveyor belt?
Why do these articles always talk about burning the tracks onto a CD and then ripping that CD to get mp3s? Can't you just use FAAC/D?
I don't have an mp3 player and have never used iTunes. If this means that I == dumb, I'll only need this explained to me once.
To a certain group preoccupied with doomsday, these projects are laudable but share a deep flaw: they are Earth-bound. A global catastrophe -- like a collision with an asteroid or a nuclear winter -- would have to be rather tame in order not to rattle the test tubes in the various ark-style labs around the world. What kind of feeble doomsday would leave London safe and sound?
When the sun goes nova the test tubes on the Moon will be rattled too. We need to put this stuff on something like Voyager. If an asteroid hits it's damage to life is mostly climate-driven. That would have very little effect on the Scandinavian "doomsday vault." Ditto for nukes. Who would waste a nuke on some out of the way Arctic research station? Ever read On the Beach?
Whatever its merits as a film, 'Training Day' has made history by becoming one of the first titles to be released on both the Blu-ray and HD DVD formats. In our first head-to-head comparison, we found the HD DVD to be superior. The unfortunate cropping of the Blu-ray image, coupled with more noticeable compression artifacts and an overall darker cast, can't compete with the more consistently pleasing presentation of the HD DVD. Also a strike against the Blu-ray version is that both the Dolby TrueHD and Dolby Digital-Plus soundtracks have been dropped in favor of plain old Dolby Digital, and even the disc's menu navigation is more clunky and with less interactive functionality. Certainly, this Blu-ray release delivers fine video quality in its own right, but the format's backers will need to step it up if they are going to win the hearts and minds of early adopters over HD DVD.
Kiss Kiss Bang Bang
With our second Blu-ray versus HD DVD battle on 'Kiss Kiss Bang Bang,' we again declare victory (although by a smaller margin) to the HD DVD verison. Most of the same problems we found with 'Training Day' on Blu-ray -- namely the picture cropping (though it is likely a player issue) and darker cast -- reappear again here. The absence of HD DVD's Dolby Digital-Plus tracks on Blu-ray is problematic, and I still find Blu-ray's clunky menu navigation quite irritating. Though with 'Kiss Kiss Bang Bang' Blu-ray has proven it can deliver moments of stunning high-def as good as HD DVD, it is still not delivering that level of quality as consistently. Very close with this one, but still no cigar.
Rumor Has It
I must say, our first Blu-ray versus HD DVD comparisons continue to yield surprises. I wasn't expecting to see much difference in video quality between the two formats with 'Rumor Has It...', yet the two discs did bear noticeable differences, with the HD DVD boasting better detail and a more film-like look. And Warner has again dropped the Dolby Digital-Plus option from the Blu-ray version. However, the Blu-ray is a good $5 cheaper than the pricey $39.95 list price the studio is charging for the HD DVD/DVD combo version, so at least Blu-ray has that going for it. But even with its higher list price, in this reviewer's opinion, the HD DVD release delivers overall better bang for the buck.
The "no hassle" (meaning, you don't have to worry if your old OS and the new one match up) is to get the (most expensive) Ultimate edition. I find that mildly interesting.

It's a superconducting tokamak.
The new part is the fact that it uses superconducting magnets. Tokamaks have been used since the 70's.
The MMOG sounds pretty neat. I will never play it (nothing like enough time) but it sounds like it has the potential to do quite well.

I should also mention that if the full Windows Vista Ultimate costs $450 in the US it will probably cost 450 pounds in the UK. Ouch!
