Spencer learned asymptotics directly from renowned Hungarian mathematician Paul Erd<"o>s (1913-96), and shares some insights with other students of mathematics who have a knowledge of first year calculus and perhaps some background in probability and graph theory. Among the topics are an infinity of primes, Stirling's formula, integration in Asymptopia, from integrals to sums, unicycle graphs, Ramsey numbers, large deviations, primes, asymptotic geometry, algorithms, potpourri, and really big numbers.
