  • Ah, yes, quite a few systems use that. Iirc, when I first got into research I believe it was SPSS that have me pause (maybe STATA) when dates seemed to reference day in the 60s. It's been a while so I don't remember the specifics, but I always thought it was a neat way to handle dates.

    Maybe it was 1 January 1970, the Unix epoch

    Because of relativistic effects, from your point of view on the train you would just walk forward. But you would notice a strange effect while the trains were accelerating: your atomically synchronized wristwatch the clock you can see out the window has slowed down and stopped counting time. So it seems that your journey to the front of the train takes no time at all.

    From someone standing on the side of the tracks catching a glimpse of you and the train as you whizz by, the front of the train is moving at light speed. You're at the back of the train completely frozen still, unable to move forward because the front of the train is moving away at light speed.

    Weird things happen when you're talking about the limits of physical reality.

  • Sound is air vibration

    Sound is not exclusive to air, it can be generalized to vibrations in any media. Whale song and dolphin echolocation are certainly sounds, and we're almost always talking about them propagating in water rather than air.

    which has to travel from one place to the next

    No, that isn't how sound works. In air this would be a description of wind, not sound.

    just transfer kinetic energy to the adjacenct atom

    This is actually a good description of how sound waves propagate.

  • I'm not sure who told you that an installation on a USB thumb drive should boot "almost instantly" - that's a much slower device than a proper HDD or SSD, and it's normal for booting off of those to at least take a bit of time. The slow boot and the slow performance when running are probably both the same thing - slow disk I/O. A fast CPU helps run computations quickly, but installing and launching programs involves a lot of writing and reading files, which doesn't have much to do with CPU speed.
