Limits to Cycles and Harmony in Revolutions

This article discusses difficulties and rewards associated with research and publication on the topic of cycles. Experiences and highlights are mainly drawn from two books by the author: Predictions, Simon and Schuster, 1992, and Conquering Uncertainty, BusinesWeek Books (McGraw-Hill), New York, 1998. Much of the content of these books has appeared over the years in various articles published in this journal.
