  The 26 dimensions of Closed Unoriented Bosonic String Theory are interpreted
as the 26 dimensions of the traceless Jordan algebra J3(O)o of 3x3 Octonionic
matrices, with each of the 3 Octonionic dimenisons of J3(O)o having the
following physical interpretation: 4-dimensional physical spacetime plus
4-dimensional internal symmetry space; 8 first-generation fermion particles; 8
first-generation fermion anti-particles. This interpretation is consistent with
interpreting the strings as World Lines of the Worlds of Many-Worlds Quantum
Theory and the 26 dimensions as the degrees of freedom of the Worlds of the
Many-Worlds.
