Böcker av Augustus De Morgan

From the end of antiquity to the middle of the nineteenth century it was generally believed that Aristotle had said all that there was to say concerning the rules of logic and inference. One of the ablest British mathematicians of his age, Augustus De Morgan (1806-71) played an important role in overturning that assumption with the publication of this book in 1847. He attempts to do several things with what we now see as varying degrees of success. The first is to treat logic as a branch of mathematics, more specifically as algebra. Here his contributions include his laws of complementation and the notion of a universe set. De Morgan also tries to tie together formal and probabilistic inference. Although he is never less than acute, the major advances in probability and statistics at the beginning of the twentieth century make this part of the book rather less prophetic.

In the preface to this work, mathematician Augustus De Morgan (1806-71) claims that 'The most worthless book of a bygone day is a record worthy of preservation.' His purpose in writing this catalogue, published in 1847, was to provide an accurate record of the early history of publishing on arithmetic, but describing only those books which he had examined himself. He surveyed the library of the Royal Society, works in the British Museum, the wares of specialist booksellers, and the private collections of himself and his friends to compile a chronological list of books from 1491 to 1846 (the final book being a work of his own), giving bibliographical details, a description of the contents, and sometimes comments on the mathematics on display. De Morgan's Formal Logic and a Memoir of Augustus De Morgan by his widow are also reissued in the Cambridge Library Collection.

Many of the earliest books, particularly those dating back to the 1900s and before, are now extremely scarce and increasingly expensive. We are republishing these classic works in affordable, high quality, modern editions, using the original text and artwork.

First notions of logic (preparatory to the study of geometry) "", has been considered a very important part of the human history, but is currently not available in printed formats. Hence so that this work is never forgotten we have made efforts in its preservation by republishing this book in a modern format so that it is never forgotten and always remembered by the present and future generations. These books are not made of scanned copies of their original work and hence the text is clear and readable. This whole book has been reformatted, retyped and designed.

On the Study and Difficulties of Mathematics is an unchanged, high-quality reprint of the original edition of 1898.Hansebooks is editor of the literature on different topic areas such as research and science, travel and expeditions, cooking and nutrition, medicine, and other genres. As a publisher we focus on the preservation of historical literature. Many works of historical writers and scientists are available today as antiques only. Hansebooks newly publishes these books and contributes to the preservation of literature which has become rare and historical knowledge for the future.

One of the key works on the development of logic, de Morgan's work forms the bridge between the researches of Hamilton and Boole. His greatest contribution to scientific knowledge undoubtedly lay in his logical researches; and the subsequent development of symbolic logic, with its powerful influences on both philosophy and technology, owes much to his fundamental work. Augustus de Morgan (1806 - 1871) was awarded the position of first Professor of Mathematics at University College in London in 1828. He founded the London Mathematical Society and was its first president.

An important figure in mathematical logic and abstract algebra, Augustus De Morgan (1806-71) also wrote wittily on paradoxical and illogical thinking through time. Edited by his widow and published in 1872, this entertaining work parades all varieties of crackpot, from circle-squarers to inventors of perpetual motion machines.
