Interesting Numbers for Interested Folks

Excellent read for those who like numbers… and those who are curious about numbers.


I’m not a mathematician, nor do I qualify as being a scientist, but I am a very curious person, and there’s lots about numbers to stimulate one’s curiosity. For example:
• Why is the length of a mile 5,280 feet?
• What is the “Golden Ratio?”
• Why is time based on units of 60 rather than on units of 10?
• What is the largest meaningful number that exists?
• Why is the number 43,252,003,274,489,856,000 important?
If questions such as these stimulate your interest, this book is for you. If not, there are lots of incurious people in the world and you have plenty of company. In this book, Chapter 1 is about numbers in general; Chapter 2 covers memorable numbers; Chapter 3 deals with weights and measures; and Chapter 3 deals with weights and measures; and Chapter 4 discusses extraordinary numbers.

About the Author

After being educated in economics at Yale University, David Ritchey served five years as an officer in the U.S. Navy, including a year in Vietnam. Back in civilian life, he initially became a businessman as he had been trained but, suffering from post-traumatic stress disorder, he dropped out, got a divorce, moved to a remote old stone farmhouse and took up fine art photography as his vocation, winning over 60 awards during the next fifteen years.

During that period, he became fascinated with the psychology and neurology of both creativity and metaphysics and returned to school to train as a psychotherapist. During his fifteen years of clinical practice specializing in hypnotherapy, he undertook a twelve-year project to research and write about such subjects and his first book, The H.I.S.S. of the A.S.P., was published in 2003. Writing proved to be every bit as rewarding as photography and became his primary vocation. Being an inveterate learner, he focused on non-fiction subjects, enjoying the research as much as the writing. His more than forty published works have won over 25 literary awards. His books can be found at and online book stores.

His avocations have included scuba diving, sailing, skiing, tennis, golf, gardening, woodworking, dogs, magic, bridge, and Scrabble. He has two adult children, Harper and Mac, and one almost-adult grandchild, Brendan. He lives in historic Bucks County, Pennsylvania, and spends most of his time either writing or engaging in stimulating conversations over restaurant meals with close friends.
