Angels & Demons

Saw "Angels & Demons" yesterday. It was better then the previous one and containing more historical and factological inaccuracies :)

For instance annihilation of a electron and positron (anti-electron) creates two gamma quants, which means that anybody in close proximity will get a healthy radiation dose. The 250mg antimatter yields about 2*10^23 gamma quants and the proton/anti-proton annihilation would yield probably bunch of exotic particles. The famous e=mc^2 shows about 22.4*10^12 J. In short this helicopter has to be damn high to prevent the radiation killing off everybody on the ground or the air is actually dense as a lead!

But I suppose in this age of forgiveness and tolerance Dan Brown can be spared and avoid to being burnt on stake for performing so many scientific heresies :P
