The Physics Teacher

This month's cover shows an elegant Lissajous figure adapted from the cover of Thomas Greenslade’s new book Adventures with Lissajous  Figures (2018, Morgan & Claypool Publishers), created on his double-elliptic harmonograph.  See A Reproduction Lissajous Figure Machine for more about Lissajous figures, and some connections to music, history, and art.
