Evidence supporting quantum information processing in animals

              Evidence supporting quantum            information processing in animals                    James A. Donald                    1068 Fulton Av                    Sunnyvale, CA 94089-1505                    USA I show that quantum systems can rapidly solve some problems for which finite state machines require a non- polynomially large time. This class of problems is closely related to the class of problems that animals can solve rapidly and effortlessly, but are intractable for computers by all known algorithms. 1. Introduction      Animals, including very simple animals, can rapidly and effortlessly perceive objects, whereas computers take nonpolynomial time to do this by all...

ARMIES OF CHAOS

                          ARMIES OF CHAOS -      Before anyone proposes more gun control, he or she should know  about a simple, deadly weapon 4 times as powerful as Dirty Harry's  legendary .44 Magnum -- and at least twice as concealable -- that  _can't_ controlled.        This simple, deadly weapon can be made by anyone -- even a  child -- with unpowered hand tools in an hour's time using $5 worth  of materials, most of which are available around the house anyway.   In traditional form it's reusable an unlimited number of times, and  modern plastics have rendered its disposable version electronically  undetectable.  You can clear a room with such a weapon (more of a  hand-held directional grenade than a gun -- sort of a recycleable  Claymore mine) and it's just one of hundreds of similar time-proven  designs. ...
