About this title

Synopsis

"An Introduction To The True Astronomy: Or, Astronomical Lectures Read In The Astronomical School Of The University Of Oxford" by John Keill surveys an 18th-century program of astronomy instruction that blends theory with computation and instrumentation. It locates the Copernican system within an experimental tradition, using dense geometry, trigonometry, tables, and worked examples to derive ephemerides, calendars, and celestial tables. Core topics include time and calendars (apparent versus mean solar time, equation of time, obliquity, Meton cycles, Gregorian reform), planetary theory and ephemerides (heliocentric and geocentric positions, eccentricity, ellipses, mean and true anomalies, orbital elements), and Halley’s and others’ methods for locating stations, conjunctions, and true positions. The text also covers projection and geometry (orthographic projections, projected ellipses, parallelograms), instrumented teaching with globes and quadrants, and extensive reference tables and epochs. Interleaved problem sets (PROBLEM I–XVI) and worked numerical examples, including Jupiter’s station, illustrate computation and observation. The volume concludes with an appendix on globes and an index, aimed at students and practitioners of astronomy.

Store Description

**Please note our transit times are from the date of dispatch.** We first started out as ?The Paperback Exchange,? a chain of physical bookstores where we would part exchange your beloved books for new stories to transport you to faraway places. However, as shopping started to evolve to online shops and marketplaces, we bid our stores goodbye to become ?PBShop.? This transition has only allowed us to blossom as we now ship thousands of titles to book lovers across the globe. We pride ourselves in being a community of local book lovers which allows our passion and devotion to shine in everything we do. In 2020 we not only celebrated our 20th birthday but our 1st birthday as being completely employee owned after becoming an E.O.T in September 2019. We are proud to be different and embrace standing apart on a book mountain by working from a virtual inventory which allows us to provide thousands of books that may be difficult to get for your bookshelf or your studies. Working with a number of different suppliers allows us to explore other avenues such as puzzles, sheet music and even stationery so we really do have something for everyone. Life is about being versatile in all realms of existence. If this is your first purchase with us, or you are a returning customer, we would like to welcome you to the PBShop family, for there is no friend as loyal as a book. We are a company who put our customers at the centre of everything we do as we understand the importance of reading because once you learn to read, you will forever be free. There are a whole lot of things in this world of ours that we are yet to explore, which is why we will forever inspire curious minds.
