Islamic fundamentalism: How bad thinking leads to violence

We live in strange times. Times where the availability of space-age weapons can be debated among people who hold bronze-age beliefs in witchcraft, magic underwear, flying donkeys and horoscopes. Despite all accusations singling out the Muslim faith as the source of violence, there’s no lack of dangerously delusional people out there in all walks of […]

Device can theoretically trap a light 'bit' for an infinite amount of time

(Phys.org)-Researchers have designed a nanoscale device that, under ideal conditions, can confine a “bit” of light (that is, light with a single precise energy value) for an infinite amount of time. Although a physically realized device would inevitably lose some of the trapped light due to material imperfections, the researchers expect that it should be possible to completely compensate for this loss by incorporating some form of optical gain like that used in lasers, so that in principle the lifetime can be infinitely large even in a real device.
