|777 Mathematical Conversation Starters shows that there are few degrees of separation between mathematics and topics that provoke interesting conversations. The topics presented in this unique book are accessible to mathematicians and non-mathematicians alike. They include thought-provoking conversation starters such as: the value of fame; why language matters; the anatomy of thought; how we know what we know; how the Pythagorean theorem (with very little physics) shows that Einstein was correct about time dilation and distance contraction; and how mathematics produces intuition-defying examples. The format is unique, too: Topics (conversation starters) are numbered, extensively cross-referenced, and divided into small digestible units. Published for the first time in 777 Mathematical Conversation Starters are original quotes from Joshua Lederberg, Ron Graham, Jay Leno, Martin Gardner, and many others.
