RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while typing up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...

Watch 32 Metronomes Synchronize with Each Other

If you place those 32 metronomes on a rigid surface, they will continue to run out of synchrony forever. If instead you place them on a moveable platform, it will begin oscillating side to side with increasing amplitude until the discordant rebels finally comply. There is probably a social behavior parallel somewhere, but the more important principle at work is the likening the system (metronomes + moveable platform) to a resonant circuit with feedback. Surely someone reading this can supply an equation for us that models the phenomenon.
