On this auspicious Day of Pi 2020, Einstein would be celebrating is 141th birthday. As usual a person like Albert Einstein might be reflecting on the nature of time as he contemplates the progression of time throughout his own life and the events and intervals between them in space-time which have defined his progression through space-time.
Which leads me to my next Book Suggestion. Time is an elusive concept yet it defines our lives. It's a tough subject to tackle and I think this book does a superb job of it. Written by experimental physicist Richard Muller, "Now: The Physics of Time" is a read very much worth your time on this Day of Pi 2020!
