as well as several books on philosophy and theism. Whittaker's bibliography in the Biographical Memoirs of Fellows of the Royal Society includes 11 books and monographs, 56 mathematics and physics articles, 35 philosophy and history articles, and 21 biographical articles, excluding popular and semi-popular articles published in magazines such as Scientific American. In the bibliography compiled by McCrea in 1957, there are 13 books and monographs and the same journal articles, also excluding popular articles. Among other topics, Whittaker wrote a total of ten papers on electromagnetism and general relativity. Whittaker & Watson Whittaker was the original author of the classic textbook A Course of Modern Analysis, first published in 1902. There were three more editions of the book all in collaboration with George Neville Watson, resulting in the famous colloquial name Whittaker & Watson. The work is subtitled an introduction to the general theory of infinite processes and of analytic functions; with an account of the principal transcendental functions and is a classic textbook in mathematical analysis, remaining in print continuously since its release over a hundred years ago. It covered topics previously unavailable in English, such as complex analysis, mathematical analysis, and the Special functions used in mathematical physics. George Frederick James Temple noted that it was unmatched in these aspects "for many years". The book was an edited set of lecture notes from the Cambridge Tripos courses Whittaker taught and contained results from mathematicians such as Augustin-Louis Cauchy and Karl Weierstrass which were relatively unknown to English speaking countries. A. C. Aitken noted the books have been widely influential in the study of special functions and their associated differential equations as well as in the study of functions of complex variables. Analytical Dynamics of Particles and Rigid Bodies Whittaker's second major work, A Treatise on the Analytical Dynamics of Particles and Rigid Bodies was first published in 1904, and quickly became a classic textbook in mathematical physics and analytical dynamics, a branch of classical mechanics. It has remained in print for most of its lifetime, over more than a hundred years, and has been said to have "remarkable longevity". The book represented the forefront of development at the time of publication, where many reviewers noted it contained material otherwise non-existent in the English language. The book was a landmark textbook, providing the first systematic treatment in English for the theory of Hamiltonian dynamics, which played a fundamental
