  1. Re:Longyearbyen? on Norway to Wire North Pole · · Score: 5, Informative
    From infoplease.com:

    Longyearbyen , town and administrative center of Svalbard, on Isfjorden, Spitsbergen island. It is a coal-mining settlement, founded (1905) by an American company and named after the American miner J. M. Longyear. Its coal mines were transferred to a Norwegian company in 1916. It was destroyed (Sept., 1943) by German battleships but was quickly rebuilt.

    Color manipulation has often been employed to enhance otherwise subtle variations, like the afore-mentioned clouds. I suppose you'll color-calibrate infrared images so that they are invisible to the naked eye? Anyway, Mars is not redder than I think. I've seen it with my own eye, I know what color it is, and I'd prefer to see enhanced images of it.

    I remember my first eclipse. It was 1979 (? I was only 8). My dad and other amateur astronomers set up telescopes with solar filters near an old cemetery. It was awesome.

  8. Re:Just another WIMP-seeking experiment on Search for the Missing Universe · · Score: 1
    The article is remarkably light in details, not even mentioning whether or not the experiment is looking for neutrinos or something else.

    Neutrinos aren't WIMPs, so they have mentioned that it is looking for something else. The new lab is the news. A large number of experiments have or will be performed there.

    the ISS ....was placed into a rapidly-decaying orbit not because that was a good idea (it isn't) but because the shuttle could get there

    It was necessary. The Earth's magnetic field is what holds radiation (energetic ion) levels down to tolerable levels. The magnetic field gets weaker and the radiation levels get higher as one moves further from the planet (radiation belts make the story a little more complicated beyond 1.5 Earth radii).

  11. Re:probability on X-Ray Satellite Coming Down Tonight · · Score: 3, Informative

    An implicit assumption in your argument is that the incoming satellite will fall as one piece (and you ignored the cross section of that piece, but that was ok as it's a lot smaller than your 217 km^2 human). Also, only the total square area of humans needs to be 217 km^2, not an individual human's size.

    A 1 m^2 human has a 1:1.68E12 chance of being hit by one piece. In 100 million people, the chance of one person being struck is 1:1.68E4. Then 1.68E4/2000 = 8 is the number of expected pieces. I picked 100 million people as a wild guess of the number of of people in the strike zone, but since Indonesia has the greatest population in the zone, I'm probably not too far off.

    Hubble has 2 instruments capable of spectrometry and imaging in infrared or near-infrared wavelengths: the Near Infrared Camera and Multi-Object Spectrometer and the Space Telescope Imaging Spectrograph. It wasn't totally unrealistic to expect images along with spectra.

  16. Re:Wha? -- Becomes Hruh? on Do Neutrinos Have Mass? · · Score: 4, Informative

    The three neutrinos are each associated with a lepton (electron, tau, muon). The electron neutrino indeed has no charge. Electron neutrinos are typically emitted in beta+ decays or electron captues, both events involving a nucleus swallowing or spitting out an electron.

    the internal dynamo within our parent star is not understood quite as well as we thought

    Huh? Actually scientists have always considered stellar and planetary dynamos to be very enigmatic. No one has ever claimed they knew them "well." The story isn't about the dynamo, it's about how the heliosphere's shape changes in response to magnetic fields on the surface. As for the double north pole, the article states "it's a fairly normal side-effect of the solar cycle."

    it's not any better for the environment

    Wrong. The use of biodiesel uses carbon pulled from the sky, not the ground. Also, the University of Montana claims its BioBus produces far fewer obnoxious pollutants compared to any type of petroleum. The biodiesel is esterified with alcohol, so it is an oxygenated fuel. That's why it burns so clean.

    These humans are being used as a massively parallel computer to control nuclear fusion? Why don't the robots just use the even more massively parallel computer that runs the Matrix to control the fusion? No matter whether the humans are beig used as energy or computing resources, they produce less than they consume.

    If he changed history, then the world whose history he studied so carefully for stock information is not the world he ended up in. It seems probable that the stock market would react to his first trades (ones that he had thye most reliable information on) in an unpredictable manner (he soaked up millions of dollars after all, so he became a big time player). Eventually stock prices would no longer match what he had read in the history books. I can only conclude that he didn't change history or he would have been less successful.

    DNA can be made from scratch, but the longer the sequence the more errors will be in it. Thus you can make a polio virus but not an elephant. IT is much better to start with whole segments of DNA.

  25. Chicken Little on Top Physicist Advocates Scientific Self-Censorship · · Score: 1

    The idea that humans would ever be capable of doing experiments capable of destroying the universe is laughable. Supermassive black holes have been 'experimenting' with energy ranges and densities that we can never hope to achieve. Furthermore, in an infinite universe like ours, some alien civilization somewhere already would have destroyed it were it possible. Small black holes made by scientists will solve the problem of their own existence by evaporating. The dangers of nanotechnology have also been overstated. Having said that, the greatest threats to humanity are nuclear weapons and biological agents like viruses.
