Is That a Big Number? (Oxford University Press, 2018) is a book that those of us who feast on numbers will absolutely adore, but will also tease the palates of those for whom numbers have previously been somewhat distasteful. This book helps us not only to realize the relative magnitudes of many of the numbers which surround us, but also helps us understand precisely how and why our understanding of the universe often comes down to the numbers which describe it. It’s just a shame that Pythagoras, who was reputed to say that “All is number,” isn’t around to appreciate it.
