Oct 14 at 14:56 comment added Edwin Ashworth '... The difference in kind, rather than in degree, that distinguishes nuclear weapons from others (to which Mr. Bernstein alludes) ...' [Harvard Hollenberg; 1984; in NYT] // But yes; these are not well-defined. It is quite legitimate to class deflagrating and detonating explosives separately rather than ... er ... scalarly. But I'd say intrinsically even more appropriate to distinguish chemical and nuclear reactions / weapons. // It depends on how these things are classified. The chosen hypernym.
Oct 13 at 20:29 comment added Michael Harvey @EdwinAshworth - as I mentioned somewhere else (question about any difference in meaning between 'detonate' and 'explode' ), gunpowder is a low explosive that deflagrates, while the others are high explosives that detonate.
Oct 13 at 18:50 comment added Edwin Ashworth A pertinent example is that the different explosive forces of chemical explosives such as gunpowder, ammonium nitrate, nitroglycerine and Semtex exhibit differences of degree. But nuclear explosives exhibit a difference in kind.
