Beryllium is valuable in the manufacture of nuclear weapons,China recently used some tipping their ICBMs.One atom of it was used in an experiment to decide the fate of Schroedinger's cat.From. . ...http://www.sciam.com/explorations/061796explorations.html The recent breakthrough of single photon emission in Britain brings quantum manipulation/encryption tantalizingly closer.The states days are almost certainly numbered but getting back to the cat.The Schroedingers cat experiment is based on the standard model of Quantum mechanics.The SMQM,if true means a universe must exist for every physical possibility.The notorious *parallel worlds* theory. This could guarantee uncrackable encryption yet its a big swallow for some,not just pussy.The double slit experiment is even cited as providing evidence for neighboring universes.(D.Deutsch.new scientist.july.01.)Its truly bizarre to see exactly what some present *concrete* beliefs are really based on.Shared hallucinations indeed,possibly even kitty litter. Is there a human Schroedinger? What of ralph Mc Gehee? Would looking to hard for his missing usenet posts kill him? Uncrackable quantum encryption will save ralph and us from the out of control rogue terror state yet if the SMQM breaks down even an higgs boson's worth then we could all be back to square one.
