This week, Facebook ruffled some feathers with the invention of a new unit of time – the ‘flick’. Facebook’s ‘Flicks’ are designed to sync with the screen refresh rate of devices, to help programmers ...

A University of Birmingham scientist has built a "mini-universe" that takes a step toward answering one of science's biggest questions: "What is time?" Publishing his findings in Physical Review ...

Scientists successfully measured an event using zeptoseconds, which is an incredibly brief fraction of a second. The time it took for a photo to pass through a hydrogen molecule was measured at 247 ...

Add Yahoo as a preferred source to see more of our stories on Google. A time lapse image of a clock's hands and face. Determining the passage of time in our world of ticking clocks and oscillating ...

A team of researchers has demonstrated the ultimate sensitivity allowed by quantum physics in measuring the time delay between two photons. By measuring their interference at a beam-splitter through ...

Scientists have been able to measure the ultrashort time delay in electron photoemission without using a clock. The discovery has important implications for fundamental research and cutting-edge ...

EPFL physicists have found a way to measure the time involved in quantum events and found it depends on the symmetry of the material. "The concept of time has troubled philosophers and physicists for ...
