A Treatise of Mathematical Instruments

A Treatise of Mathematical Instruments by Robertson, John. paperback edition. ISBN: 9781931468114.

A Treatise of Mathematical Instruments contains a complete description of a range of tools that are useful in mathematics, surveying, architecture, navigation, drafting, gunnery, physics, and illustration. It covers the sector (a form of calculator that predates the slide rule), the gunners calipers, the proportional compasses, and a variety of lesser instruments. Examples show how to use all of the instruments, with extensive details on architectural drawing, plane geoemtry, spherical trigonometry, unit conversion, surveying, perspective drawing, and ships guns (cannons and mortars). 12 plates of figures illustrate and clarify the text. Anyone who has ever drafted a plan or drawing by hand or recalls having used a slide rule will be interested in this book. Those who has only used electronic devices will learn something new. Additionally, a wealth of historical details are revealed through the extensive figures and the text. Modern notes include a biography of the author John Robertson, an explanation of some of the notation used in the book, and a brief commentary and history on mathematical methods, surveying, navigation, and architecture.
