We delve deep into the science and interrelationships ofFour Famous mathematical constantsEuler's Number e, The Ludolphine Constant ( Pi ), Pythagoras' Constant and The Ratio of Phidias ( phi ). Along the way we assess the usefulness of diverse methodsof computing these numbers, techniques dating from theBronze Age to the twenty-first century. From the earliest days of visible life to our own times, tiny animals have plowed or burrowed the deep sea floorin systematic, geometrical paths.They often seem to have conformed to the mathematics ofour famous numbers! Can this really be true? We consider the evidence. Profusely illustrated with original research, algebraic derivations, full academic references, and acomprehensive index "Four Famous Numbers"will appeal to enthusiasts, undergraduates and teachersin higher education.
