The Physics Teacher

This month's cover features two naturally occurring heart shapes, an acoustic cardioid tucked inside a fractal valentine. The latter image, the Mandelbrot set in vivid red and black, is by Matthias Hauser (Fine Art America: https://fineartamerica.com/profiles/matthias-hauser.html);for more about the former, see Visualizing Sound Directivity via Smartphone Sensors by Scott H. Hawley and Robert E. McClain Jr.
