Space, Time, Matter by Hermann Weyl Excellent introduction probes deeply into Euclidean space, Riemann's space, Einstein's general relativity, gravitational waves and energy, and laws of conservation. "A classic of physics." — British Journal for Philosophy and Science.
Hydrodynamics and Hydraulics by Daniel Bernoulli, Johann Bernoulli Hydrodynamica (1738) marks the first appearance of many modern topics, from kinetic theory of gases to principles of jet propulsion. Hydraulica (1743) deals primary with hydraulics. 104 illustrations.
