ONE, TWO, THREE by David Berlinski

ONE, TWO, THREE

Absolutely Elementary Mathematics

KIRKUS REVIEW

Philosopher and math populizer Berlinski (The Devil’s Delusion: Atheism and Its Scientific Pretensions, 2008, etc.) takes on the challenge of explaining the logical foundation of the elementary operations of arithmetic.

It’s no easy task. Indeed, it was not until the late 19th century that mathematicians were inspired to develop the axioms (unproven assumptions) enabling the development of theorems to prove the legitimacy of all those rules of thumb you learned in high school—e.g., that the product of two negative numbers is positive, or to divide fractions you invert the divisor and multiply. Along the way, mathematicians developed set theory, which showed that the operations possible with numbers could be generalized to define arcane structures called rings or fields. Why bother, Berlinski writes in the introduction, noting that most people dislike math. However, he continues, the reason is because such work has the grandeur of the absolute, of something deep in the human imagination. So readers with an open mind to, say, Peano’s five axioms for the natural numbers, may be putty in the hands of Berlinski. The author examines the world of integers, embracing positive and negative numbers, and then fractions, and he introduces many of the hallowed names of 20th-century mathematicians and logicians with charming asides and literary references. The author also explains the various laws of associativity and commutativity that the numbers obey, as well as the value of proof by induction and how it derives from Peano’s fifth axiom.

“New math” for adults this is not. Rather, Berlinski delivers a tour de force by a mathematician who wants the intellectually curious and logically minded student to understand the foundations and beauty of one of the major branches of mathematics.
