The calculation of exact positions of stars, the Sun and the celestial bodies of the solar system is a prerequisite of successful practical work in astronomy. This text gives the necessary background of spherical astronomy and celestial mechanics from the practitioner's point of view, and collates all the formulae and numerical values needed to calculate precise ephemerides. The clear structure of the book allows easy use of the material in computer programs. Students, lecturers and amateurs in astronomy will find the book an invaluable reference in their daily work, lectures or lab courses.
Practical Astronomy with your Calculator, first published in 1979, has enjoyed immense success. The author's clear and easy to follow routines enable you to solve a variety of practical and recreational problems in astronomy using a scientific calculator. Mathematical complexity is kept firmly in the background, leaving just the elements necessary for swiftly making calculations. The major topics are: time, coordinate systems, the Sun, the planetary system, binary stars, the Moon, and eclipses. In the third edition there are entirely new sections on generalised coordinate transformations, nutrition, aberration, and selenographic coordinates. The calculations for sunrise and moonrise are improved. A larger page size has increased the clarity of the presentation. This handbook is essential for anyone who needs to make astronomical calculations. It will be enjoyed by amateur astronomers and appreciated by students studying introductory astronomy. • Clear presentation • Reliable approximations • Covers orbits, transformations, and general celestial phenomena • Can be used anywhere, worldwide • Routines extensively tested by thousands of readers round the world
Using clear and logical routines, this book shows how a variety of problems and exercises in modern astronomy can be readily solved with a scientific calculator. This edition includes new sections on mutations, aberration and selenographic co-ordinates and
Practical Ephemeris and Daily Planetary Guide is a unique source ofinformation that allows you to plan your life in accordance withtraditional astrology regardless of how advanced your knowledge ofastrology is.In this book you will find the foundations of astrological planningexplained. You will also learn the cyclical and planetary factors totake into consideration and how they influence the course and theoutcome of your activities and proceedings. All the explanations aregiven in a straightforward, concise and easy-to-grasp manner.The Ephemeris tables provided in the book are calculated for sixdifferent time zones - Delhi, Dubai, London, Los Angeles, New York andSydney. These tables do not follow a classical format but are adjustedto the theory presented in the book, so it would be easy to apply it andto pick up the suitable period of time for your new beginnings. An easyplanning algorithm is provided and an Ephemeris table for January 2020is analysed in detail demonstrating what the month is good for, how toapply the algorithm and the theory given.This book is based on traditional astrology, so you will not find anyastropsychology or ambiguous interpretations inside. Only roughtraditional astrology knowledge adapted to modern life and madeeasy-to-understand and to apply.
Now in its fourth edition, this highly regarded book is ideal for those who wish to solve a variety of practical and recreational problems in astronomy using a scientific calculator or spreadsheet. Updated and extended, this new edition shows you how to use spreadsheets to predict, with greater accuracy, solar and lunar eclipses, the positions of the planets, and the times of sunrise and sunset. Suitable for worldwide use, this handbook covers orbits, transformations and general celestial phenomena, and is essential for anyone wanting to make astronomical calculations for themselves. With clear, easy-to-follow instructions for use with a pocket calculator, shown alongside worked examples, it can be enjoyed by anyone interested in astronomy, and will be a useful tool for software writers and students studying introductory astronomy.
