In this case, two one dimension strings S 1 and S 2 are selected.
We use this two dimensions string to balance the number of tasks across the processors.
In order to explain the appearance of only four space-time dimensions string theory assumes that the other dimensions are somehow folded away or "compactified" so that they are no longer visible.
By now, the 11-dimension string theory models of his earlier books (to which Mr. Greene helpfully steers the reader for background material) are looking downright commonsensical.
Unlike the microscopic hidden dimensions of string theory, the new dimension implied by Resurrection has "broken though" into everyday reality and demands a response -- even if that response is to actively ignore it.
The construct with the strongest positive correlation with the second dimension is String literals.
Various difficulties arise, however ('the curse of dimensionality') as the number of dimensions increases, even for quite small numbers of dimensions or string length, since the dimensionality increases exponentially with the number of residues being changed.
In this regard, the extra dimensions of string theory have proved a major hurdle.
Imagine the journey from the first million-million-million-millionth of a second to the present inflation field where we all exist in10 dimensions of string theory.
Gauss's curved space, Einstein's curved spacetime and the bizarre rolled-up dimensions of string theory might have pushed lesser writers into clotted obscurantism, but Mlodinow handles them all with aplomb.
In particular, the likely explanation is that the neutrinos are taking a short-cut through one of the extra dimensions which string theory postulates are hidden among the familiar four of length, breadth, height and time.
