His method is explained in detail in this chapter. Dodgson introduced it in his Game of Logic, which he used to teach syllogisms to children, and which he then developed in his Symbolic Logic, Part I. The rest of the chapter is concerned with further work that Dodgson carried out, but which was not published at the time because of his premature death at the age of 65.","PeriodicalId":269174,"journal":{"name":"The Mathematical World of Charles L.

The chapter is divided into subject areas: geometry (including his alternative version of Euclid’s parallel postulate), trigonometry (for which he devised a new set of symbols), algebra (his work on determinants), logic (where the work of Bartley and others has led to a significant re-evaluation of Dodgson’s involvement), voting theory (on which he was in contact with a number of senior politicians), and probability, and concludes with a section on ciphers and cryptology. There has been a growing interest by scholars in Dodgson’s serious mathematical work since the third quarter of the 20th century, particularly as more of it has been published.","PeriodicalId":269174,"journal":{"name":"The Mathematical World of Charles L.

His book concerned the study of determinants, an algebraic construct that had come to the fore during the 19th century, and presented a new method, called the method of condensation, for evaluating them; this method was due to Dodgson and was the subject of his only refereed journal paper. The book also applied his results to the solution of simultaneous linear equations, and included the proof of a theorem describing when a system of linear equations is consistent. The book’s impact and influence are discussed in the concluding section of this chapter.","PeriodicalId":269174,"journal":{"name":"The Mathematical World of Charles L.

Critical of standard methods of voting such as first-past-the-post, single-transferable-vote, etc., he presented examples to show their weaknesses. He also proposed a system of proportional representation, and communicated this to newspapers and to Parliamentarians of the time. His Principles of Parliamentary Representation discusses the assignment of seats to multi-member districts and to parties within each district to parties. It is only recently that his contributions to the theory of voting have been recognized.","PeriodicalId":269174,"journal":{"name":"The Mathematical World of Charles L.

This chapter concerns a wide range of recreational games and puzzles that he used to inform and entertain his child-friends and his colleagues. Among the topics included are problems involving time, probability, geometry, algebra, and arithmetic, and there are sections on calculating the days of the week, memorizing numbers, testing for divisibility, and on a wide range of other topics. Dodgson compiled puzzles for some of his young friends, and some of these were published in his lifetime (including some that he included in letters to magazines). Others were found in his papers after his death and published subsequently.","PeriodicalId":269174,"journal":{"name":"The Mathematical World of Charles L.
