On the move: strontium atoms in an atomic clock. (Courtesy: Steven Burrows and Ye Group/JILA) An optical atomic clock has been used by physicists in the US to study the effects of spin–orbit coupling.

The Planetary Orbit Clock could sit on your desk for days, even years, even lifetimes before you realized the clock’s very simple logic: it’s read from overhead. Working like the original clock (the ...
