On the History of Gunter's Scale and the Slide Rule During the Seventeenth Century


Book Description

Unlike some other reproductions of classic texts (1) We have not used OCR(Optical Character Recognition), as this leads to bad quality books with introduced typos. (2) In books where there are images such as portraits, maps, sketches etc We have endeavoured to keep the quality of these images, so they represent accurately the original artefact. Although occasionally there may be certain imperfections with these old texts, we feel they deserve to be made available for future generations to enjoy.










A History of the Logarithmic Slide Rule and Allied Instruments, and On the History of Gunter's Scale and the Slide Rule During the Seventeenth Century


Book Description

The slide rule, with its many variations, has been vital to mathematics and engineering since its invention in the 17th century. Interest in this field has grown dramatically and collectors can still find much material at affordable prices. Unfortunately there has been little information available except for manufacturers manuals and catalogs, making this reprint of Cajori's classic particularly valuable. Also included with this reprint of the 1910 edition is Cajori's extensive article On the History of Gunter's Scale and the Slide Rule during the 17th Century, published by the University of California in 1920, which sets forth his subsequent findings. There is also a helpful explanatory introduction by Dr. Robert K. Otnes, editor of the Journal of the Oughtred Society




Slide Rules


Book Description

In the hopes of "preserving these delightful devices for future generations," this collector of slide rules covers everything one could possibly want to know about this crude form of analog computer: from its invention in the 17th century to manufacturers- retailers, 1850-1998, and the Oughtred Society for collectors. Includes a glossary with biographies, patent data, component specs, dating and valuing, care, historical milestones, and illustrations







A History of Mathematical Notations


Book Description

Described even today as "unsurpassed," this history of mathematical notation stretching back to the Babylonians and Egyptians is one of the most comprehensive written. In two impressive volumes-first published in 1928-9-distinguished mathematician Florian Cajori shows the origin, evolution, and dissemination of each symbol and the competition it faced in its rise to popularity or fall into obscurity. Illustrated with more than a hundred diagrams and figures, this "mirror of past and present conditions in mathematics" will give students and historians a whole new appreciation for "1 + 1 = 2." Swiss-American author, educator, and mathematician FLORIAN CAJORI (1859-1930) was one of the world's most distinguished mathematical historians. Appointed to a specially created chair in the history of mathematics at the University of California, Berkeley, he also wrote An Introduction to the Theory of Equations, A History of Elementary Mathematics, and The Chequered Career of Ferdinand Rudolph Hassler.




The Papers of Thomas Jefferson, Volume 40


Book Description

This volume opens on 4 March 1803, the first day of Jefferson's third year as president. Still shaken by the closing of the right of deposit at New Orleans, he confronts the potential political consequences of a cession of Louisiana to France that might result in a denial of American access to the Mississippi. But he resists pressures to seize New Orleans by force, urging patience instead. The cabinet determines in April that "all possible procrastinations" should be used in dealing with France, but that discussions with Great Britain move forward as well. In Paris, a treaty for the cession of the Louisiana Territory to the United States is signed, and in May the right of deposit is restored. On 3 July, word reaches Jefferson in Washington of the agreement that France has sold the entire Territory for $15 million. The glorious news, which may be the most momentous that Jefferson receives while president, appears in the National Intelligencer the following day. Having received congressional approval to send an expedition to locate a continental route to the Pacific, Jefferson drafts instructions and a cipher for Meriwether Lewis and arranges for the needed instruments. Following through on a promise to a friend to give his views of Christianity, Jefferson puts his religious creed on paper, a "Syllabus" of the morals of Jesus and the comparative merits of Christianity. He intends it only for a few trusted friends.




A History of Mathematical Notations (Two Volume in One)


Book Description

Described even today as "unsurpassed," this history of mathematical notation stretching back to the Babylonians and Egyptians is one of the most comprehensive written. In two impressive volumes, first published in 1928-9 and reproduced here under one cover, distinguished mathematician Florian Cajori shows the origin, evolution, and dissemination of each symbol and the competition it faced in its rise to popularity or fall into obscurity. Illustrated with more than a hundred diagrams and figures, this "mirror of past and present conditions in mathematics" will give students and historians a whole new appreciation for "1 + 1 = 2." Swiss-American author, educator, and mathematician FLORIAN CAJORI (1859-1930) was one of the world's most distinguished mathematical historians. Appointed to a specially created chair in the history of mathematics at the University of California, Berkeley, he also wrote An Introduction to the Theory of Equations, A History of Mathematical Notations, and The Chequered Career of Ferdinand Rudolph Hassler.
