The intention of this book is to shine a bright light on the intellectual context of Euler's contributions to physics and mathematical astronomy. Leonhard Euler is one of the most important figures in the history of science, a blind genius who introduced mathematical concepts and many analytical tools to help us understand and describe the universe. Euler also made a monumental contribution to astronomy and orbital mechanics, developing what he called astronomia mechanica. Orbital mechanics of artificial satellites and spacecraft is based on Euler's analysis of astromechanics. However, previous books have often neglected many of his discoveries in this field. For example, orbital mechanics texts refer to the five equilibrium points in the Sun-Earth-Moon system as Lagrange points, failing to credit Euler who first derived the differential equations for the general n-body problem and who discovered the three collinear points in the three-body problem of celestial mechanics. These equilibrium points are essential today in space exploration; the James Webb Space Telescope (successor to the Hubble), for example, now orbits the Sun near L2, one of the collinear points of the Sun-Earth-Moon system, while future missions to study the universe will place observatories in orbit around Sun-Earth and Earth-Moon equilibrium points that should be properly called Euler-Lagrange points. In this book, the author uses Euler's memoirs, correspondence, and other scholarly sources to explore how he established the mathematical groundwork for the rigorous study of motion in our Solar System. The reader will learn how he studied comets and eclipses, derived planetary orbits, and pioneered the study of planetary perturbations, and how, old and blind, Euler put forward the most advanced lunar theory of his time.

Dora Musielak is an aerospace scientist, the recipient of two NASA research fellowships and other honors. She is a Research Professor at the University of Texas in Arlington and teaches mathematical methods to graduate students in physics and engineering. Dora Musielak is also a historian of mathematics and science. Her research focuses on both the lives of mathematicians and the scientific developments in the eighteenth and nineteenth centuries. A central topic of her scholarly exploration is the mathematical ideas that germinated and grew in Europe, starting with Euler and Lagrange, in order to discover how mathematics led to developments in physics and astronomy. Her research also includes the mathematical formulations for classical (Newtonian) and modern (Einsteinian) quantum mechanics. Dora Musielak is the author of Sophie's Diary (MAA Press), and her latest book published in Springer Biographies is a scholarly memoir of French mathematician Sophie Germain, describing her contributions to mathematics and her efforts to prove Fermat's Last Theorem. The present book is Dora Musielak's tribute to the blind mathematician who saw infinity.
