  • It was pointed out to me a while back that the paradox of tolerance is only a paradox if you consider tolerance to be a philosophical position.

    In fact, we don’t treat it like that. We treat it as a social contract, in which context it is no paradox at all to say that if you aren’t tolerant then other people aren’t obliged to tolerate you in turn










  • I would describe it as being in free-fall whenever it’s not in being held up by any interaction with a solid surface, even indirectly. I’m not sure everyone would agree with my definition, but it’s not a term you’ll see used much in serious engineering precisely because it is a bit vague.

    For example, an aircraft in flight isn’t in free-fall because it’s being held up by the air, which is in turn held up by the ground. An aircraft (or spacecraft) which has no wings is being slowed down by air resistance, but not actually held up and is therefore in free-fall.

    An ascending rocket is generating forces which hold it up, rather than transferring forces to something which won’t move (like the ground), so I would consider it to be in free-fall
