Principle of relativity those frames do not, in general experience, seem to abide by the same laws of physics. In classical physics, fictitious forces are used to describe acceleration in non-inertial reference frames. The special principle of relativity was first explicitly enunciated by Galileo Galilei in 1632 in his "Dialogue Concerning the Two Chief World Systems", using the metaphor of Galileo's ship. Newtonian mechanics added to the special principle several other concepts, including laws of motion, gravitation, and an assertion of an absolute time. When formulated in the context of these laws, the special principle of relativity states that the laws of mechanics
The Einstein Theory of Relativity The Einstein Theory of Relativity The Einstein Theory of Relativity (1923) is a silent short film directed by Dave Fleischer and released by Fleischer Studios. In August 1922.."Scientific American" published an article explaining their position that a silent film would be unsuccessful in presenting Albert Einstein's theory of relativity to the general public. They argued that only as part of a broader educational package including lecture and text would such film be successful. "Scientific American" then went on to review frames from an unnamed German film reported to be financially successful. Six months later, on February 8, 1923, the Fleischers
