There's a passage in 2001 that struck me as wrong. They're describing the spinning of the carrousel in Discovery and there's the following quote.
The problem of shaving was also solved; there would be no weightless bristles drifting around to endanger electrical equipment and produce a health hazard.
However, a centrifuge doesn't create gravity, it just affects items that are touching it or recently touched it. So wouldn't the bristles still be free floating? They have the relative velocity of the shaver, but not towards the ground like it would be in gravity, they would travel in a diagonal to the floor, right?
