"The binomial theorem is usually quite rightly considered as one of the mostimportant theorems in the whole of analysis." Thus wrote Bernard Bolzanoin 1816 in introducing the first correct proof of Newton's generalisation of acentury 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 integralexponents, and may also appear incongruous to one familiar with Newton'sseries for rational exponents. Yet his statement was a sound judgment back inthe 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 essentialtool for root extraction, through Newton's generalisation and its central rolein 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 necessarydetails, yet still readable and understandable for those with a limited mathematical background, say at the Calculus level or just below that.The present book, with its many citations from the literature, will be ofinterest to anyone concerned with the history or foundations of mathematics.
