Wndsn Quadrant Telemeters: Graphical Telemetry Computers: Low Tech Distance & Altitude Nomographs: Instruments for the Mastery of Time and Space

The 6th and final edition of the Grimoire Quadrantis Telemetrum celebrates 10 years of Telemeter development, research, and worldwide exploration. The Wndsn Quadrant Telemeter is a low tech, naked-eye, observational instrument that allows the user to measure angular size, distance, height or depth of object, slope, altitude, or elevation via various inputs and sighting methods. In addition, the Quadrant Telemeter is a trigonometry-based, graphical, analog computer that provides built-in functions to directly process or convert the acquired values. Featured is an inclinometer as well as scales for the computation of sine, cosine, and tangent for any given angle. It is possible to solve right-angled and non-right angled triangles without the use of digital means. This 6th edition adds, among many other updates, the computation and graphical representation of twilight times as well as a number of navigational stars. This manual is about the theory and practice of the instrument.This book is a description of the tools, principles, functions, and methods which together make up the operating system of the Quadrant Telemeter and its specialized variants. It's a practical manual for the beginner, as well as a study guide and textbook for the advanced user. It includes tutorials for all functions and methods, as well as the graphically worked formulas and a number of useful reference tables.The 6th edition expands upon the 4th and 5th edition, now clocking in at 564 pages, 244 figures, 39 tables, 50 equations, 230 cross-references, 144 glossary entries, and 104 bibliography entries.From the changelog:Many simplified and/or expanded explanations.Once again dozens more and refined graphics.Streamlined and tightened layout (otherwise this edition would be way over 600 pages long).Some new naming conventions for clarity.Addition of stars to the Quadrant, including how to use the data.New scales and symbols explained.Added required and acquired Telemeter skills.Community contributions are once again featured throughout from users in the field.Expanded glossary and bibliography.Errata from prior versions processed.
