A very interesting lecture on the MONAD Calendar-Clock, which has been in development since 2006. The idea for a Planetary Calendar-Clock first came to Dr. Whitten as he was working on an illustration for a book (Owner’s Manual) where he was describing the impact the 4 seasons have on our physiology. Over the years, he has built various Calendar-Clock models, both real and virtual. Thinking far outside of the box, Dr. Whitten’s lectures are informative and enlightening.
