  1. no, spin is quantized per particle on "Spin Battery" Effect Discovered · · Score: 1

    "More spin" is really "more aligned spin". In normal matter spin is disordered and aligned randomly in either of two states.

  2. isnt that control magnetic energy? on "Spin Battery" Effect Discovered · · Score: 1

    Theres a limit on how much a material can be magnetized before its self-repellent magnetic energy rips it apart.

  3. I think the shuttle program is ended on Discovery Launch a No-Go, Again · · Score: 1

    Broken, old rockets combined with a hyper-cautious NASA means we wont be seeing shuttle launches again.

  4. live music is so much richer on Young People Prefer "Sizzle Sounds" of MP3 Format · · Score: 1

    Listening to electronic mediated music - amplified, broadcasted, analog or digitally recorded always loses something. I try to listen to live performance whenever I can.

  5. trek is a multi-generational series on Could Fuller Take Trek Back To TV? · · Score: 2, Insightful

    44 years spans at least three cultural generations.
    The original Trek was military culture familiar to the WWI and Korean era veterns of the 1960s.
    The New Generation was 'yuppies in space' - well-healed baby boomers, team organization, yada, yada, yada.
    The newer Treks never quite caught the pathos of the younger generations. The GenY's are individualistic and artistic, sort of like "herding cats in space" - not your corporate team players. Another Roddenberry scifi show called Andromeda captured this pathos better.
    I cant really characterize the newest adults - the 9/11, Iraq War, and Second Depression generation. The generation always plugged into electronic communication and networks.

    The New Generation made an interesting prediction that seems to be coming true - the death of television. I recall one episode where some 21st century types were revived from hibernation and asked about television and money and the crew said they didnt do those any more. Roddenberry's uptopia did not have money or TV.

  6. Edison almost invented it on The First Phone Call Was 133 Years Ago · · Score: 1

    Randall Stross , Silicon valley historian and NY Times technology columnist, wrote an interesting biography of Edison a few years back. He compared Edison [favorably] to modern Silicon Valley entrepenuers.

    With regard to telephones, Edison was obssessed with increasing telegraph line capacity. He invented several multiplexing schemes. One scheme would transmit/decode messages at different frwquencies multiplexed on the same line. His competitors made the conceptual leap of using ALL frequencies to transmit the voice instead of clicks. At least Edison developed the first useful microphone for the telephone then.
    Another multiplexing scheme pre-recorded telegraph messages which would be played across the liens at superhuman speeds, recorded at the other end, then played back slow enough to transcribe. The turned into the more successful audio record player then.

  7. technology and race inflation on Could Fuller Take Trek Back To TV? · · Score: 1

    Each series had to trump the previous with more fantastic technology and odder races.
    This became kind of weird int he prequel series Enterprise.

  8. Viewing schedule on Heavens Above on ISS To Become Second Brightest-Object In the Sky · · Score: 1

    I look for the ISS several times a month. A schedule is here In a given month the ISS is visible about one week in the morning sky and one week in the evening. The orbit moves to be optimal for US or Soviet launches at different times.

  9. habitable zone = smaller, slower planets on NASA's Kepler Telescope Launched Successfully · · Score: 1

    Most of planets discovered so far been through the doppler velocity method which is biased to large, fast, close-in planets, because thats what causes the larger and more easily detectable doppler shifts. Kepler use the "transit method" the temporary dimming of a star by a planet crossing in front of it. It should be able see smaller, slower, far out planets.

    Modeling suggests about one in thousand stars will have planets and will be tilted in the right way to see planetary transits. Kepler will watch a couple hundred thousand stars for three years and perhaps discover a couple hundred planets.

  10. technological convergence too on Game Developers Becoming Similar To Hollywood Studios? · · Score: 1

    The main article was about business model convergence. When I go to computer graphics conference like SIGGRAPH the two technology appear to borrow more of each other's ideas. The movie animation house are leverage the cheap and ubiquitous gamer hardware, i.e. GPUs. The gamers are employing more visual and story arts in solidifying their products.

  11. similar with Lynch's Dune, not Harry Potter on Watchmen Watched · · Score: 1

    People hadnt pre-read it were confused. But I thought it was a decent abridgement. I thought the HP movies are better than the books.

  12. filling 'black hole' between Oscars and summer on Watchmen Watched · · Score: 1

    OK, OScar movies are out Dec to Feb and summer starts in May. The studios often put their dogs out inbetween. Nice to have something interesting to watch then.

  13. distribute airbags too on Congress Mulls API For Congressional Data · · Score: 3, Informative

    I routinely look at large bills on thomas.loc.gov to see whats in them. 485 last minute earmarks in the stimulus bill and 9000 in the 2009 budget bills. Enough to make you gag.

    These are sort of like an ebay auction: 24 hours before the vote these start to stream in. Often they are placeholders "text to be supplied" or very obscure references to the organization designated for the earmark. Not even the toiling interns who are supposed to vet these for their bosses can keep up last minute submissions.

    Ironically the TARP bill last year was very streamlined and only had one earmark. But that was a controversial federal judge raise.

    Another nausea in the bills are that 90% are resolutions commending people or organizations in their districts. this reads like the gossip pages in the newspapers. You see this if look at the full list of recent bills.

  14. "1984", "Brave New World", "Animal Farm" on UK School Introduces Facial Recognition · · Score: 1

    What did you expect fromt he UK?

  15. good idea to have national "CIO" on America's New CIO Loves Google · · Score: 1

    Information Technology is such a large fraction of both the federal budget and national economy that the president should have direct point guy on it.
    Just hope he doesnt cathc the democratic disease of big, pushy government.

  16. to the contrary - important for nanotech on Scale Models Can "Compute" Casimir Forces · · Score: 2, Informative

    Nano-machines may not work as predicted unless you take into account the vacuum energy fluctuations. The sign of the force appears to be shape and material dependent.

  17. premise of Species movies on DNA-Radio, Tune In To Your Chromosomes · · Score: 2, Informative

    Scientist implant DNA sequence downloaded by SETI. They didnt understand it, but it turns out to be BAD. Thats how the evil aliens propagate themselves.

  18. midwest farms a productive source of meteorites on Meteorite Hunters Find the West Texas Fireball · · Score: 3, Interesting

    I've heard of number of "hunters" who strap a magnetometer on their ATVs and criss-cross fallow fields looking for iron-stones within the top couple feet. This is the easiest terrain to routinely run ATVs over. Teh slashdot-types whould automate this with GPS and artificial intelligence.

  19. MSR dominates SIGGRAPH on Roundup of Microsoft Research At TechFest 2009 · · Score: 2, Interesting

    Last several years MSR has co-authored as many as 20% of the main papers. This is remarkable considering the main paper track has a 85% rejection rate. Some of the rejects go to secondary tracks, but only their abstracts are published then and not really science then (reproduceable).
    The sad thing is I see so little of this research making it in main stream MSFT commercial products. I hear from mainstream MSFT developers of a cultural rift between them and the "effete research snobs". Stockholders are starting to grumble about the drain of multi-billion dollar research lab on company returns.

  20. amazon makes money whatever reader you use on Amazon Releases iPhone Kindle Software · · Score: 1

    Due to DRM of bookware.
    They hope you have a better reading experience and spend more money if you use their reader.

  21. googling your age or race may be illegal on Should Job Seekers Tell Employers To Quit Snooping? · · Score: 1

    Anything prohibited by US unemployment laws. Some HR depts are now telling their people not to do this. A court case may decide this.

  22. if your ever attend a scifi-con or comic-con on Star Trek Fragrances · · Score: 1

    You will see any kind of fanatic product.

    Unfortunately you the fan frangrance too - pudgy, sweating, teenage males who dont groom often enough.

  23. "average" is one these abused single-numbers too on The Formula That Killed Wall Street · · Score: 1

    People have gotten better at saying which kind of average now whether arithmetic or median. But it isnt really descriptive of the distribution of statistics. You hear abuse from the price of houses to income tax policy.

  24. K&R's null-terminated string in C on Null References, the Billion Dollar Mistake · · Score: 1

    They should be shot for that one :-) This is lead to so many costly buffer-overflow virus attacks. Early languages like FORTRAN and COBOL had safer strings, but not as elegant as C. You had to pre-declare string storage size in early compilers.

  25. mine: Mosaic, NetScape, IE, Firefox on Hearst To Launch E-Reader For Newspapers · · Score: 1

    I've been reading newspapers on the web since the beginning. I really hate the ones that insert two or three video ads.
