  1. Aiming for an Ig Nobel prize? on Death Metal Music Inspires Joy Not Violence, Study Finds (bbc.com) · · Score: 1

    This research looks like it was custom made to go for an Ig Nobel.

  2. Re:Links to the actual study? on Researchers Study "Harbingers of Failure," Consumers Who Habitually Pick Losers · · Score: 1

    I heard you could rent it in DIVX format. https://en.wikipedia.org/wiki/...

  3. How about "The Housekeeper and the Professor? on Ask Slashdot: Mathematical Fiction? · · Score: 1

    I really liked "The Housekeeper and the Professor" by Yoko Ogawa. Maybe its not exactly what you were looking for since the math is pretty simple and is not the sole focus of the story, but the story itself is excellent and its hard not to read the book without being inspired by how beautiful mathematics is.

  4. This is interesting, but the title is misleading. on Quantum Measurements Leave Schrödinger's Cat Alive · · Score: 3, Insightful

    The headline was a bit misleading. You still can't measure a quantum state without having its superposition collapse to what was measured. If I understand what the article is saying properly, these scientists are not able to peak into the box to measure "Schrodinger's Cat's" state of aliveness, but they can still peak to see if the cat is a tabby or a calico. If fur pattern isn't a good quantum number, then that will cause the "cat" to change its spots, but later probes can be used to nudge it back to its original state. Meanwhile, you haven't disturbed the "cat's" aliveness or deadness. The important part seems to be being able to "nudge" certain states with probes to get some information out of the system without really changing it.

  5. Re:Spent fuel stored on site? on Further Updates On Post-Tsumami Japan · · Score: 1

    There are a lot of intermediate isotopes from the main uranium fission reaction in the spent fuel rods and although the main reaction can not take place because the storage geometry they still produce heat from those secondary reactions. That heat is a small fraction of that from the main reaction that runs a nuclear power plant, but it still must be carried away somehow or the spent fuel rods can get extremely hot. They are put into a large amount of water in a system which has a heat exchanger for several years until these secondary reactions have become so weak that there is no risk of damaging them anymore. They are then sent to dry storage. The problem with transporting them off-site at the beginning is that you *must* have a large amount of water covering them both to dissipate heat and to block radiation. Its very difficult to transport them when they need to be in so much water during the entire transportation process. As a result they are usually stored on site. I think the reason why they are on the roof of the Fukushima Daiichi reactors is because they can then lift the spent fuel rods with a crane on the roof and move them directly to storage very quickly without the risks involved in transporting them to a location somewhere else across the plant.

  6. Phys. Rev. E?? on Online "Guilds" Mirror Real Life Gangs · · Score: 1

    It is kind of a interesting paper, but how in the world did it get into Physical Review? Just because you do some statistics doesn't mean you are doing research in physics. Shouldn't this have been sent to a sociology journal?

  7. Re:The end of residential computer networks on New TN Law Forces Universities To Patrol For Copyright Violations · · Score: 1

    One of UT Knoxville's solutions was to block all P2P file transfers on the university network. I have no idea of how much the software/hardware to do this cost and I hate to think how many computers on campus were comprimised by people downloading patches from untrustworthy websites when the World of Warcraft expansion came out last week (since Blizzard's official updater is excruciatingly slow when it can't use bittorrent).

  8. Abuse of the word "science". on Science's Alternative To an Intelligent Creator · · Score: 1

    How are unobservable "multiverses" and a theory which not only is unprovable, but can not make any predictions any more scientifically satisfying than having an intellegent creator? It seems to me that this is basically replacing one religion with another and has nothing to do with real science (which must be testable and make predictions).

  9. What do the publishers want? on Modern LaTeX Replacement? · · Score: 1

    Maybe I am being naieve here, but doesn't what you use depend on what the journal asks for? I've been using LaTeX for years since its the preferred format for APS journals. At this point I'm past the learning curve for LaTeX, so I don't really struggle much with it. Some journals prefer Word instead so if you submit to those journals you have to use Word with its inane equation editor. Its kind of a pain, but the important thing is to make the paper acceptable to the journal so it gets published and people can build on your work.

    Now if its something simple like class notes, the output quality isn't all that critical and you can use whatever you want. I personally use LaTeX, but just use whatever is easiest.

  10. Re:Mercury switch vs Gyroscope? on Gyroscope Gives CellPhones 'Tilt Control' · · Score: 1

    Hasn't this already been done, basically using a mercury switch? I remember the game Korokoro Kirby(Kirby's Tilt 'N Tumble in the US) for the gameboy color which used an interface like that. You made him move around the screen by tilting the gameboy and made him jump over things by shaking it. No gyroscopes were used (as far as I could tell).
