Frontiers of Pachydermy



Quantum theory takes this subjectivity  to a strange extreme:
 There is no elephant,
 only blind men.
-- George Johnson, Fire in the Mind (1995), p. 140

That epigram, pried from its context,  has a pleasingly Minimalist ring, rather like “Garfield minus Garfield”, though in our case  what is missing  is any elephant.


As for the sense in context:  The elephant represents a sought-for deterministic objective value for some quantized parameter (such as position, velocity, polarization).  The blind-men are the scientists or their measuring-instruments.  To their dismay, they discover that no such value exists:  the elephant is absent.

String theory, too, has (as in the parable of the blind-men) suffered from an overplus of versions, none canonical.  But now:

For the five string theories,
M-theory serves as  the unifying pachyderm.

  1. There is indeed an elephant and men are inside, that's their real problem.

    "Deterministic objective values" are only in the clock of Laplace. This post is then 200 years old.
