  We review Cantorian and Non Commutative Spacetime, work which has occupied El
Naschie in the past several years. These concepts are now the subject of
intense research, thanks to Quantum Gravity, Quantum Super String Theory and a
few other approaches. It now appears that we are on the verge of a breakthrough
in finding solutions to longstanding problems, like the unification of
gravitation with other fundamental interactions and the question of the mass
spectrum, another recent area of El Naschie's work.
