Dear Sir,

         I think it is misleading (if not just wrong) to say that the energy of particles in the LHC, 14 trillion electron volts, is "trillions of times more powerful than the energy released by dynamite" (Vol 26, No 8, Page 34). Fourteen trillion electron volts is about two microjoules; by comparison, just a gram of TNT is said to release about 4 kilojoules of energy. Certainly, integrating over time and particles and including the huge currents circulating in the magnets, the LHC will involve impressive amounts of energy. But the energy of a single particle is still less than the kinetic energy of a honey bee in flight; and, unlike dynamite, the LHC is unlikely to explode.

It's true they didn't mention how much dynamite.. but do you really think that's what they were going for? ("The magnets will bend particles along a circular path as they accelerate to 99.99999 percent the speed of light and attain energies approaching 14 trillion electron volts, trillions of times more powerful than the energy released by dynamite.")
