Reid was not herself a professional mathematician, but came from a mathematical family that included her sister
Julia Robinson and brother-in-law
Raphael M. Robinson.[11] She had worked as a schoolteacher, but by the time of the publication of From Zero to Infinity she was a "housewife and free-lance writer".[1] She became known for her many books about mathematics and mathematicians, aimed at a popular audience, of which this was the first.[11]
Reid's interest in number theory was sparked by her sister's use of computers to discover
Mersenne primes. She published an article on a closely related topic,
perfect numbers, in Scientific American in 1953, and wrote this book soon afterward.[4] Her intended title was What Makes Numbers Interesting; the title From Zero to Infinity was a change made by the publisher.[8]
Topics
The twelve chapters of From Zero to Infinity are numbered by the ten decimal digits, (
Euler's number, approximately 2.71828), and , the
smallest infinite cardinal number. Each chapter's topic is in some way related to its chapter number, with a generally increasing level of sophistication as the book progresses:[4][5][10]
Chapter 0 discusses the history of number systems, the development of
positional notation and its need for a placeholder symbol for zero, and the much later understanding of zero as being a number itself. It discusses the special properties held by zero among all other numbers, and the concept of
indeterminate forms arising from
division by zero.[4][5][10]
The topics of Chapter 2 include
binary representation, its ancient use in
peasant multiplication and in modern computer arithmetic, and its formalization as a number system by
Gottfried Leibniz. More generally, it discusses the idea of number systems with different bases, and specific bases including
hexadecimal.[4][5]
In chapter 6, Reid brings in the material from her earlier article on
perfect numbers (of which 6 is the smallest nontrivial example), their connection to
Mersenne primes, the search for
large prime numbers, and Reid's relatives' discovery of new Mersenne primes.[4][5]
Mersenne primes are the primes one unit less than a
power of two. Chapter 7 instead concerns the primes that are one more than a power of two, the
Fermat primes, and their close connection to
constructible polygons. The
heptagon, with seven sides, is the smallest polygon that is not constructible, because it is not a product of Fermat primes.[4]
Chapter 8 concerns the
cubes and
Waring's problem on representing integers as sums of cubes or other powers.[4][5]
The final chapter, Chapter , provides a basic introduction to
Aleph numbers and the theory of infinite sets, including
Cantor's diagonal argument for the existence of uncountable infinite sets.[4][5]
The first edition included only chapters 0 through 9.[1] The chapter on infinite sets was added in the second edition, replacing a section on the
interesting number paradox.[12] Later editions of the book were "thoroughly updated" by Reid;[4] in particular, the fifth edition includes updates on the search for
Mersenne primes and the proof of
Fermat's Last Theorem, and restores an index that had been dropped from earlier editions.[9]
Audience and reception
From Zero to Infinity has been written to be accessible both to students and non-mathematical adults,[4] requiring only high-school level mathematics as background.[7] Short sets of "quiz questions" at the end chapter could be helpful in sparking classroom discussions, making this useful as supplementary material for secondary-school mathematics courses.[6][10]
In reviewing the fourth edition, mathematician
David Singmaster describes it as "one of the classic works of mathematical popularisation since its initial appearance", and "a delightful introduction to what mathematics is about".[4] Reviewer Lynn Godshall calls it "a highly-readable history of numbers", "easily understood by both educators and their students alike".[6] Murray Siegel describes it as a must have for "the library of every mathematics teacher, and university faculty who prepare students to teach mathematics".[10]
Singmaster complains only about two pieces of mathematics in the book: the assertion in chapter 4 that the Egyptians were familiar with the 3-4-5 right triangle (still the subject of considerable scholarly debate) and the omission from chapter 7 of any discussion of why classifying
constructible polygons can be reduced to the case of prime numbers of sides.[4] Siegel points out another small error, on algebraic factorization, but suggests that finding it could make another useful exercise for students.[10]
