The Electromagnetic Vector Potential field, usually labeled A is also something that many treat as merely a mathematical convenience. However, it can be directly observed using a Superconducting QUantum Interference Device (SQUID).
It is fitting that we use a similar quantum phenomenon, oscillations of the Cesium atom to measure time.
