    Guiding Principles for Research and Teaching

    "The theory must be natural and incisive enough that it generates recognizable concepts; a theory which ends in an opaque jumble of formulae has served no purpose." --- Peter Whittle

    "If a topic cannot be explained in a freshman lecture, it is not yet fully understood." --- Richard Feynman
