This equation by Michio Kaku describes strings in 10 dimensions (please don't ask how). It cannot be the final equation, says Discover magazine in August 2005, because it does not incorporate the 11th dimension that is central to M-theory. "If physicists can find a master version of this formula that includes membranes and describes quantum reality, they will have the final version of string theory, and possibly the equation of the universe." Unfortunately Discover doesn't tell us what any of the symbols stands for.
