- This is ridiculous. It's as if they were to argue that negative numbers
- don't "really exist" (whatever that means), so you can't have any
- gravitational acceleration, because a = -GM/r. It doesn't mean anything.
- I would say, though, that most physicists think "discrete" implies some
- minimum interval, in the sense of quantization, like integral multiples
- of e or hbar. Since you can always find a rational between any two
- irrationals, eliminating the irrationals brings you no closer to this
- sort of discreteness.

- I guess this is why I always start to wonder when I see good reviews of
- Paul Davies's books in more-or-less scientific magazines (like _Nature_?)
- They usually contain some phrase like "even though Davies makes some
- outlandish speculations, the book is a good popularization of blah blah"
-
- Don't they realize that the outlandishness is what novices carry away from
- reading the book? Not only does it mislead people about the facts, it
- misleads them about what science is: something where boffins sit about
- all the time thinking wild ideas (what mathematicians do!) as opposed to the
- actual gruntwork of science. Gruntwork isn't flashy, but it's what's
- necessary to separate science from speculation. Pop books too often fail
- to be about _science_ by fudging this.
