Explore the intricacies of Mach's principle and its implications for physics in this comprehensive talk by Professor André Koch Assis. Delve into the historical context of Newton's and Leibniz's ideas on space and motion, and examine the famous bucket experiment. Analyze Mach's critique of Newtonian concepts and his thought experiments on the influence of distant stars. Compare predictions according to Newton and Mach, and investigate the connection between inertia and gravity. Discover the contributions of Galileo, Dirac, Schrödinger, and Einstein to this field. Examine thought experiments on Earth's shape and rotation, and learn about Foucault's pendulum. Explore the relationship between Mach's principle and Einstein's general relativity, and understand why Mach rejected Einstein's theory. Gain insights into relational mechanics, Weber's gravitational force, and the potential unification of gravitation with electromagnetism. This talk offers a deep dive into fundamental physics concepts and their historical development.
