Mathematical Astronomy with a Pocket Calculator

From back cover (1978): A new, radically different and timely introduction to astronomy for the lay or student reader, this book examines the ways in which the various bodies of the Universe function and interact. Always making use of the most recent results from advances in space technology, observational techniques and theoretical considerations, Understanding Astronomy looks at the Solar System, the stars, nebulae and galaxies, treating also subjects such as quasars, pulsars, neutron stars and black holes. An appendix tells how to make a small telescope at minimal cost.
