Yankovsky Accessible classic of gravitation theory and celestial mechanics explains methods used by physicists in studying celestial phenomena, including perturbed motion, satellite technology, planetary rotation, and motions of stars. 1959 edition.
Forces and Fields: The Concept of Action at a Distance in the History of Physics by Mary B. Hesse This in-depth look at the science of ancient Greece examines the influence of antique philosophy on 17th-century thought, plus modern concepts: quantum mechanics, wave-particle duality, the uncertainty principle. 1961 edition.
