Thomas precession gives a correction to the precession of a Foucault pendulum. Also housed are Newton's Cradle, the color spectrum, and Foucault pendulum. Several vector diagrams are often used to demonstrate the physics underlying the Foucault pendulum. It takes the idea of the Foucault pendulum and uses a vibrating element. On the eastern side there is a contemporary version of a Foucault pendulum. The main foyer houses a large Foucault pendulum. Many physical systems precess in a similar manner to a Foucault pendulum. One of the easiest examples is the Foucault pendulum. A two-story Foucault pendulum is in the lobby. Braga compared the idea to the Foucault pendulum in the rotunda at Griffith Observatory. The classic example of a nonholonomic system is the Foucault pendulum. The Foucault pendulum is a physical example of parallel transport. For example, the rotation of the Earth can be observed using a Foucault pendulum. The school also had a Foucault pendulum that was dedicated in 1959. He published his last academic paper, on the Foucault pendulum, at the age of 90.
