New study shows nanoscale pendulum coupling

In 1665, Lord Christiaan Huygens found that two pendulum clocks, hung in the same wooden structure, oscillated spontaneously and perfectly in line but in opposite directions: the clocks oscillated in anti-phase. Since then, ...

Clock mystery from 350 years ago is shedding light on human health

In 1665, the inventor of the pendulum clock, Christiaan Huygens, noticed that two of his clocks hung on the same wall would eventually sync up, so that their pendulums swung in opposite directions in perfect time. This "insensible ...

Relativity of rotational motion confirmed

It has been one hundred years since the publication of Einstein's general theory of relativity in May 1916. In a paper recently published in EPJ Plus, Norwegian physicist Øyvind Grøn from the Oslo and Akershus University ...

Tic toc: Why pendulums swing in harmony
