|A Treatise on the Binomial Theorem
“The binomial theorem is usually quite rightly considered as one of the most
important theorems in the whole of analysis.” Thus wrote Bernard Bolzano
in 1816 in introducing the first correct proof of Newton’s generalisation of a
century and a half earlier of a result familiar to us all from elementary algebra.
Bolzano’s appraisal may surprise the modern reader familiar only with the
finite algebraic version of the Binomial Theorem involving positive integral
exponents, and may also appear incongruous to one familiar with Newton’s
series for rational exponents. Yet his statement was a sound judgment back in
the day. Here the story of the Binomial Theorem is presented in all its glory,
from the early days in India, the Moslem world, and China as an essential
tool for root extraction, through Newton’s generalisation and its central rˆole
in infinite series expansions in the 17th and 18th centuries, and to its rigorous
foundation in the 19th.
The exposition is well-organised and fairly complete with all the necessary
details, yet still readable and understandable for those with a limited mathe-
matical background, say at the Calculus level or just below that.
The present book, with its many citations from the literature, will be of
interest to anyone concerned with the history or foundations of mathematics.
