Synopses & Reviews
In its first two editions, Practical Astronomy With Your Calculator enjoyed tremendous success. Using clear and logical routines, the author shows how a variety of problems and exercises in modern astronomy can be readily solved with a scientific calculator. The author keeps complexities and mathematical sophistication in the background, leaving only those elements necessary for making actual calculations. Further expanded and improved in response to suggestions from enthusiastic readers, the third edition now includes sections on generalized coordinate transformations, nutations, abberation, and selenographic coordinates. In addition, improvements have been made to the sunrise and moonrise calculations, and the page size has been increased to enhance the clarity of presentation. This is an excellent handbook for anyone who enjoys making astronomical calculations.
