    String Theory: An Evaluation

    "For nearly seventeen years now most speculative and mathematical work in particle theory has centered around the idea of replacing quantum field theory with something that used to be known as 'Superstring Theory', but now goes under the name 'M-Theory'. We've been told that 'string theory is a part of twenty-first-century physics that fell by chance into the twentieth century', so this year the time has perhaps finally come to begin to evaluate the success or failure of this new way of thinking about particle physics. This article will attempt to do so from the perspective of a quantum field theorist now working in the mathematical community."
