Physicists have now managed to track the passage of time inside a quantum event without using anything that looks like a ...

EPFL physicists have found a way to measure the time involved in quantum events and found it depends on the symmetry of the ...

Oscilloscopes are the workhorse instruments for time domain measurements. Most current digital oscilloscopes include about twenty-five built in measurement parameters as a standard complement. Adding ...

Measuring time might not seem like that complex of a thing. After all, we rely on simply counting seconds between the "then" and the "now." But when you really start to break time down to the quantum ...

Determining the passage of time in our world of ticking clocks and oscillating pendulums is a simple case of counting the seconds between 'then' and 'now'. Down at the quantum scale of buzzing ...

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 ...

Physicists have found a way to measure how long ultra-fast quantum events actually take—without using a clock at all.

Like the GPS satellites around the other planets in our solar system must have varying levels of velocity and gravitational time dilation as they orbit closer and further from the sun, is there an ...
