Dialogues Concerning Two New Sciences

2015 Reprint of 1954 Edition. Full facsimile of the original edition. Not reproduced with Optical Recognition Software. This is the standard translation of one of the greatest works in western science. Written near the end of his life, the book had to be published abroad and eventually led to Galileo’s condemnation. Written as a discussion between a master and two students, it sets forth its hundred experiments and summarizes the conclusions Galileo drew from those experiments in a brisk, direct style. Galileo discusses aspects of fracture of solid bodies, cohesion, leverage, the speed of light, sound, pendulums, falling bodies, projectiles, uniform motion, accelerated motion, and the strength of wires, rods and beams under different loadings and placements. This is an unabridged republication of the translation by H. Crew and A. D Salvio, with an introduction by Antonio Favaro. The work recognized as the first systematic attempt to give a mathematical treatment of kinematics. “So great a contribution to physics was “Two New Sciences” that scholars have long maintained that the book anticipated Isaac Newton’s laws of motion.” –Stephen Hawking. “Galileo … is the father of modern physics-indeed of modern science”-Albert Einstein.
