- PublicHere's why astronauts on the International Space Station can't sleep: "It's a combination of the unearthly sensation of floating in bed, constant noise, variable temperature, poor air circulation, nagging backaches and headaches, frequent shifts between Houston and Moscow time zones, and a new dawn every 90 minutes that confuses surface-accustomed circadian rhythms."

There's no reason to think we would abandon mass production just because of 3D printers. Ignoring all the very real technological limitations with 3D printers, even a magic 'make-anything-box' still loses out to economies of scale.
The whole advantage of 3D printers is that you can easily customize things. As long as you're 'downloading' designs it will necessarily be easier and cheaper to have it mass produced and delivered or bought in a store.

Peak Universe!! Choose sides. Peak Universe realists and deniers. Might as well get a head start on the whole debate. We only have a few billion years before it settles out.

I had not realized till I saw a show about the AMNH that in the age when people seldom traveled far, did not have TV, internet and color movies, that this was the only way for them to experience, in some way, creatures from far far away.
How alien all those dioramas must have been to them eyes from some time ago.
And yet, the near life-sized dioramas still captivate.

- PublicMake sure to click on the sound files half way down in this post to learn what good hasuji ("edge line") sounds like (good hasuji ensures an effective cut through target). The sound a sword can make when it is swung, known in Japanese as tachikaze, or “sword wind,” can serve as a sign. If the hasuji was right, tachikaze will sound like sharp whistling. If the hasuji was wrong, tachikaze will sound like flat whooshing, or there will be no tachikaze.
