From StarTalk.

In this StarTalk segment, Neil deGrasse Tyson, Chuck Nice, and Gary O’Reilly talk with Dean Buonomano about how brains “tell time” differently from manmade clocks. Dean contrasts oscillation-based devices (pendulums, quartz, atomic clocks) with neural timing, arguing the brain often uses evolving activity patterns (dynamics) more like an hourglass than a ticking metronome—while circadian timekeeping is driven by biochemical feedback loops that synchronize to the day–night cycle of Earth.
