Since its first European printing in 1979,
Astronomical Formulae for Calculators
met with world-wide acceptance among those looking for Astronomical algorithms.

What the Reviewers said:

"Classic reference on the topic. There are many others, but Meeus is authoritative. The best single compendium of algorithms."

                        Byte magazine

"No serious observer can afford to be without Jean Meeus' latest book. In just under 200 pages, he has covered most of the calculations that one is likely to encounter in practical, computational astronomy. The writing is crisp and clear throughout and well formatted."

Journal of the Royal Astronomical Society of Canada

"This book is a must for any amateur interested in the computational aspects of astronomy, whether his calculator is paper and pencil or a sophisticated mini-computer."

   Southern Stars, Journal of the Royal Astronomical Society of New Zealand

"In this little jewel of a book, Belgian amateur astronomer and astronomical calculator "par excellence" Jean Meeus brings together a host of astronomical formulae for observers, navigators, mathematical hobbyists, and anyone who enjoys putting a pocket calculator or home computer through its paces."
