And a further correction as quoted by Nils B.:
"You've perhaps heard from 17,000 mathematicians since this section was quoted in the 2005 Jan "Notices of the AMS", but while splitting hairs, this definition of compact is incorrect: it defines -totally bounded-, not compact. For instance, the -open- interval (0,1) is totally bounded (can be guarded by a finite number of policemen, no matter how nearsighted a policeman is) but not compact."
