-----Original Message----- Right (except that you got fission and fusion backwards). Another source of confusion that I forgot about, though, is "A-bomb" (fission) and "H-bomb" (fusion). Brain fart. Fuse means two small things turn into one large thing. Fissures are separations. __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
