	Part 1 is mainly concerned with expressing large numbers, [[Georg Cantor]] and infinity, and the [[imaginary unit]]. After disparaging the [[Roman numeral]] system for being limited to thousands (M), ''[[The Sand Reckoner]]'' system of [[myriad]]s and octades is described. In terms of one-to-one correspondences, in the world of infinity "a part may be equal to the whole". [[Aleph number]] zero is described, with aleph one related to points in a plane, and aleph two to curves. (These latter associations are not true unless the [[Generalized Continuum Hypothesis]] ~~is assumed~~, which Gamow fails to mention.) As for [[prime number]]s, the sieve of Eratosthenes is shown. The [[Fermat number]]s are given and related to primes. [[Goldbach's conjecture]] is stated: "Every even number can be written as the sum to two primes." It was an epithet of [[Gerolamo Cardano]] that stuck: square roots of negative numbers are ''imaginary''. The [[Argand diagram]] is displayed, and multiplication by ''i'' rotates the diagram counter-clockwise by a right angle. The study of [[complex number]]s then deviates into [[treasure hunting]].
