I was trained, originally, as a pure mathematician although I have always worked in applications. Since I was a student I have recognized that the methodology of mathematical thinking is very powerful as a tool for development. It has, indeed, great practical value. Henry Pollak in his excellent talk today presented many interesting examples which seem to indicate that in the field of communications this is thoroughly recognized. However, there are still many areas of industry and of other human endeavors in which skepticism is prevalent.
