coupled oscillators

A Harvard lecture demonstration in which five metronomes on a movable board gradually fall into synchronization through coupling. Removing the coupling lets them drift out of step.

Veritasium explores how synchronization arises spontaneously in nature, with metronomes, fireflies and bridges, drawing on Steven Strogatz's work on chaos and complexity.

Dean Friedman's near-hour-long introduction to synthesis, covering the building blocks of sound and the controls on a synthesizer. He slowly adjusts knobs so viewers hear what each parameter does.

Robert C. Martin's Ruby Midwest 2011 keynote argues that software architecture should express the application's intent rather than its framework. He covers separating entities, interactors and boundaries so the web, database and framework are details.

Bryan Cantrill's illumos Day 2014 talk on running Linux containers on an illumos kernel via LX-branded zones. He covers emulating Linux syscalls on SmartOS and compares Linux and Solaris-derived systems.

Dave Jones of EEVblog demonstrates that a frequency counter can detect gravity through the 2g tipover effect on quartz crystal oscillators. He shows the reading shift as the instrument's orientation changes.
