PHYS 2211 Chapter Episode 1 and 2: Episode 1 and 2 / Introduction, The law of falling bodies / Cal-Tech: The Mechanical Universe
Document Summary
Episode 1 and 2 / introduction, the law of falling bodies / cal-tech: the mechanical universe. Mechanics is concerned with why everything behaves the way it does, and how things interact with each other and why. How does it all work? is likely a question that the earliest humans asked themselves. The greeks where some of the first to make important mathematical discoveries, they developed the first concepts of pi. Copernicus realized that the earth orbited the sun, a completely revolutionary idea for the time. Galileo challenged much of the status quo, proving to be truly ahead of his time. The church considered galileo threatening to both rome and common sense, they wanted him to stop, but he continued his work regardless. Galileo discovered the law of inertia, visualized the path of projectiles, and discovered the law of falling bodies. Kepler was also a very significant contributor to physics with his law of ellipses, equal area and harmony.
