1063.0. "Bell's Inequality" by DKAS::KOLKER () Thu Apr 30 1992 20:31

    Does anyone know of any SF which makes essential use of Bell's
    Inequality. I know the the Bell Theorem is mentioned in Schroedigner's
    Cat (Robert Anson Willson) and possibly Ursula LaGuin's ansible is a
    B.T device. 
    
    What are your opinions and answers?

    Re .1:
    
    Bell's Inequality is the mathematical formula at the heart of Bell's
    Theorem, which shows what kind of correlations must exist between
    remote events depending on whether physics is "local" or "non-local."
    Physics is "local" or not depending on whether or not the correlations 
    produce data outside the range of the inequality.
    
    Quantum mechanics predicts a "non-local" result, and experiments
    confirm this.
    
    So what does the "(non-)local" business mean?  Processes are "local" when
    events are influenced only by conditions that reach the event at the speed 
    of light or slower.  "Non-local" processes don't have that limitation.
    
    The non-local effects that have been predicted by quantum mechanics and
    observed in the lab all involve the collapse of the wave function, the
    specific manner in which the probabilistic results of quantum
    calculations resolve into particular, actual outcomes.
    
    For a more detailed description of this sort of thing, see the
    ATSE::Philosophy conference, topic 221.  See also the book described in
    that topic, "Quantum Reality," by Nick Herbert.  Herbert has also
    written "Faster Than Light: Superluminal Loopholes in Physics,"
    discussed in ATSE::Philosophy, note 58.57, which came out earlier and 
    dealt with the Bell Theorem more briefly.

1063.3Is this what you are after ??SNO78A::NANCARROWTue May 12 1992 22:1318
    
    	I do not know if this is what you are after since
    the novel does not mention Bell's Theory and Iam not
    sure if you just want a novel that uses faster than light
    effects to change the world. However you may like to have
    a look at some of James Blish's novels which use the
    DIRAC transmitter. The Transmitter appears in several
    of his novels and it's invention is covered in the novel
    (sorry the book is at home and Iam not sure of the spelling)
    
    		A QUINCYNX OF TIME
    
    also the ending of one of his novels A Case Of Conscience might
    be of interest even though the novel itself may be a bit
    philosophical spiritually for you.
