### 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."
