concerning why string
theory is stable in 11 dimensions and then
compactifies a number of them, i ask
the following: how does string theory encompass
quantum mechanics which is formulated in an
infinite dimensional hilbert space ? it seems that
a transfinite cardinality would not be isomorphic
to a set of order 11.

how *do* you map an L-2 metric space of infinite
dimension into a set with 11 dimensions only ?
