    An important thing to note is that while periodic they are still finite; the periodicity ends at the edge of the crystal.

    The sound barrier increases with decreasing pressure. Higher altitudes have a higher speed of sound, so he may not have broken it.

    "If it is possible, then it's only relevant as a motivation to find a way to travel faster than light."

    Belief is relevant to human action, but the results if the action is taken are independent of belief.

    Thought experiments can lead to interesting results, some of which eventually become science. What happens if energy is negative? What happens if energy is complex? What if spacetime is quantized? What if causality is not fundamental, and is the result of lower level phenomena? etc, etc.

    If faster than light travel is impossible, humans will be limited forever. What you believe has no relevance. If it is possible, then it's only relevant as a motivation to find a way to travel faster than light.

    The weird black & white mode is IR. Lighter = hotter, essentially.

  12. Re:Parental Guidance is a must. on Laser Strikes On Aircraft Becoming Epidemic · · Score: 1

    Low-powered laser pointers are unlikely to blind anyone. High-powered lasers can sometimes be strong enough to cause eye damage even with only diffuse reflections. A rock is dangerous if you intentionally misuse it, same for slingshots, bows and arrows, pocket knives, and lasers. But lasers are far easier than the rest to accidentally misuse.

    The really FUN ones are the water-cooled ND-YAG welding/cutting lasers. Invisible beam, and the diffuse reflection can blind you from a good distance away.

    Naw, it's actually easy. The spinning motion of the drier cycle forms a wormhole, and when the socks are transported through it they end up in closets, transformed into coat hangars.
    Go, look in your closet. Did you buy all those hangars? No! Most of them used to be your socks.

    This is, I think, the more important part of the problem. A cyclist is far closer to being a pedestrian than being an automobile driver, yet we treat them as auto drivers, force them into the roads (which is very dangerous), etc.

    There's a forum that I visit regularly. The owner doesn't want ads, and can't pay for the hosting himself (it's reasonably large). So he asked for donations, and those of us in the community who could afford it chipped in. He didn't try to track us, add ads, or anything, and we chose to give what we felt the service was worth. There's now enough money set aside to pay for hosting for the next three years.

    Asimov was, by far, the most concerned with real science in his works. He wrote more nonfiction science books and essays than he did science fiction. They're both reasonably similar in the amount of science used in their fiction.

    In WWI losses were pretty much always very heavy. An F/A-18, SU-27, or a modern strategic bomber (B-1 Lancer, B-52, TU-160, etc) would be far scarier, because it would be nearly unkillable and able to attack ground targets with ease. It would also be much easier to rearm with unguided bombs, as opposed to guided missiles of a fighter.

    "ped" is Latin for "foot". "paedo" or "paido" is Greek for child. "philo" is Greek for love. So a "paedophile" is someone who wants to have sex with kids, and a "pedophile" is a foot fetishist who mixes Latin and Greek words.~
