# Action-angle coordinates

#### Action-angle coordinates

- Event time: 11:30am
- Event date: 25th March 2015
- Speaker: Chay Paterson (Formerly School of Physics & Astronomy, University of Edinburgh)
- Location: Room 2511, James Clerk Maxwell Building (JCMB) James Clerk Maxwell Building Peter Guthrie Tait Road Edinburgh EH9 3FD GB

### Event details

Completely integrable systems have as many conserved quantities as degrees of freedom, and with the right coordinates one can calculate frequencies of periodic motions -- without explicitly solving any equations of motion! In this talk, I'll introduce action-angle coordinates and solve some examples, including harmonic oscillators and the infinite potential well.
