The Mysteries Of Time

Physicists in the university’s Research Laboratory of Electronics have developed an atomic clock that takes advantage of the way atoms behave when they’ve been quantumly entangled.

A typical atomic clock works by measuring the vibrations at the atomic level of cesium-133 atoms, which oscillate with absolute consistency, 9,192,631,770 times a second. Traditionally, lasers measure a cloud of these randomly oscillating, cooled-down cesium-133 atoms. MIT’s new clock, however, uses ytterbium atoms that have been entangled, meaning the atoms behave in a uniform fashion, with the atoms oscillating in sync rather than randomly. Ytterbium’s oscillation rate is 100,000 units faster per second than cesium-133, and these oscillations can be tracked more precisely, allowing the team to measure even smaller intervals of time. In other words, they’ve achieved increased precision… More here.

So much happens in the background as we go about our daily lives. This is just one very impressive example.

  1. Fascinating! So many things are happening in science that we are unaware of that may completely change our lives.
