“Tweezer Clock” May Help Tell Time More Precisely

Pictured above: Adam Shaw, Ivaylo Madjarov and Manuel Endres work on their laser-based apparatus at Caltech. Image credit: Caltech Atomic clocks are used around the world to precisely tell time. Each “tick” of the clock depends on atomic vibrations and their effects on surrounding electromagnetic fields. Standard atomic clocks in use today, based on the atom cesium, tell time by “counting” radio frequencies. These clocks can measure time to a precision of one second per every hundreds of millions of years. Newer atomic clocks that measure optical frequencies of light are even more precise, and may eventually replace the radio-based…
