Marc explains the quantum physics principles and hardware implementation of the vintage HP 5061A cesium atomic clock.
I finally get my hands on what I consider a holy instrument: the HP 5061A Cesium clock. We'll turn it on and play with it, of course, but I'll also explain how it works in more details than most videos, both the quantum physics principle and the HP implementation. What makes it tick is just mind blowing.

Recommended as an exceptionally clear explanation of how atomic clocks work and how they are implemented in hardware.
