Oscillators are found everywhere in our universe, from the voltage controlled oscillator found inside your synthesizer, to the quartz crystal oscillator found inside your watch. The oscillations of black holes, electromagnetic fields, and sound itself shape the dynamics of our world. This episode takes you on a journey through what it means to oscillate - a fundamental concept in physics and engineering. Special guests include: Joel Green, an astrophysicist and instrument scientist at the Space Telescope Science Institute; Max Katz, a physicist and legislative fellow in the U.S. Senate; and Steve Dunnington, engineer and VP of product development at Moog Music.
