What have nuclear weapons to do with QCD? The temperatures in nuclear explosions are too low to generate quark-gluon plasma (but only by a factor of 10 [ m i n u s ] 6 ). Perhaps what they have in common is that they were both invented by physicists. But please don't blame me for this harangue, rather blame the conference organisers who accepted it.Nuclear weapons are not the only grave danger facing our society, there are plenty of competitors: global population growth, anthropomorphic ecological damage such as the greenhouse effect, the rapid exhaustion of important resources such as oil and gas, etc. What is special about the nuclear weapons danger is that it could probably be eliminated without much trouble and with a consequent benefit to all, nuclear haves and nuclear have-nots alike.
