nuclear weapon \nu"clear wea"pon\, n.
   a weapon of great explosive power, such as an atomic bomb
   or a hydrogen bomb, which depends for most of its explosive
   power on the release of energy from within atomic nuclei by a
   nuclear reaction. a fission weapon or a fusion weapon.
   the term includes atomic shells for cannon.

   atomic philosophy, or doctrine of atoms, a system which,
      assuming that atoms are endued with gravity and motion,
      accounted thus for the origin and formation of all things.
      this philosophy was first broached by leucippus, was
      developed by democritus, and afterward improved by
      epicurus, and hence is sometimes denominated the epicurean
      philosophy.

   atomic theory, or the doctrine of definite proportions
      chem., teaches that chemical combinations take place
      between the supposed ultimate particles or atoms of
      bodies, in some simple ratio, as of one to one, two to
      three, or some other, always expressible in whole numbers.
      

   atomic weight chem., the weight of the atom of an element
      as compared with the weight of the atom of hydrogen, taken

atom bomb \at"om bomb`\, atomic bomb \atom"ic bomb`\n.
   a bomb of great power in which the explosive energy is
   derived from the nuclear fission of a fissionable material,
   such as plutonium or uranium-235. it is a type of nuclear
   weapon. the strength of an atom bomb is measured in kilotons,
   i.e. the equivalent energy released by explosion of a
   thousand tons of tnt. the first atomic bomb was manufactured
   in 1945.

   syn: a-bomb, fission bomb.
