  1. Re:According to the article: on SSSCA Squirms Forward Again Thursday · · Score: 1

    Well, to be fair, your estimate that 3 million people are involved in piracy simultaneously every second, assumes that there is a 1:1 correspondence between downloads and people.

  2. Re:Isn't this a contradiction? on Quantum-Cascade Polychromatic Lasers · · Score: 1

    My definition was very general, but there was nothing incorrect about it. I was just explaining how the new Lucent laser can emit photons of various wavelengths and still fit the definition of a laser.

    By the way, most lasers ARE crystals. As you know, a semiconductor is a crystal.

    LASER = Light Amplification by Stimulated Emission of Radiation.

    Essentially, some material (usually a crystal) is excited, which causes it to emit photons. Usually, because of properties unique to the material, it will only emit photons of a certain wavelength, but this is not a requirement. Lucent's LASER is simply built using a material that emits photons of many wavelenths.

  4. Re:Geek answer: simulator on Perpetual Skislope · · Score: 2, Funny

    there are some things a simulation just can't capture

    1. laughing at that guy, who just crashed, as you ride the chair lift

    2. the sense of irony as you face-plant into a snow drift

    3. extracting snow from your thermal underwear

    4. marching up the hill to retrieve your skis

    5. realizing those guys in the chair lift are laughing at you.

  5. Re:kind of boring on Perpetual Skislope · · Score: 1

    Beginners (Green cirle, right?) on the inside, Black Diamonds on the outside. :) Yeah, but there still would be no difference in the slope of the run. Slope is what makes a run more challenging. This would be like telling an advanced skier that the black-diamond hill is the bunny hill. You just have ski it fast ;)

  6. Re:Why use a rotating disk? on Perpetual Skislope · · Score: 2, Insightful

    well, actually, a skier's top speed is mostly determined by the slope of the run, weight of the skiier, type of skis etc. your maximum speed relative to the track would be no different on the inside or outside. of course, if you ski too fast on the inside then you get to the bottom. ski too slow on the outside and you would rise to top.

  7. kind of boring on Perpetual Skislope · · Score: 1

    Wouldn't riding on a never-ending snow treadmill get a little tedious? Also, how would you accomodate the "green circle skiers" and the "black diamond skiers" on the same device? I assume the slope of this thing would not be very aggressive.
