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 ...

The ring down of the antennas is a huge bottleneck in spectroscopic measurements involving relaxation time (T2) measurements. The ring down of the antenna determines the dead time of the spectrometer.

As a species, we are obsessed about time. Our technological exploits rely on an increasingly exact knowledge of time. For example, some communications systems require frequency uncertainty 10-11 ...

Jitter is a short-term variation in the timing of a digital signal from its nominal value. There are two main types of jitter, random jitter and deterministic jitter. Random jitter is unbounded, that ...

Markus Lutz is CTO and Founder of SiTime Corporation. He is a MEMS expert, a prolific entrepreneur and inventor who holds over 100 patents. If there is one thing that modern society has in common with ...

"This book provides a introduction to the physics of time and time measurement, from an historical perspective to the modern day. It discusses the stability and accuracy of atomic frequency standards, ...

People have framed the conversation about measurement in the social sector in terms of monitoring and evaluation for decades. They shorthand it as “M and E” and serve it up as a generic, ...

Scientists are preparing to redefine the fundamental unit of time. It won’t get any longer or shorter, but it will be more precise — and a whole lot more powerful. By Alanna Mitchell Modern ...

We live in a world where time is all important. Nanoseconds mark the difference between success or failure to make an electronic transaction and where we are continuously reminded of “the time”: of ...

Humanity’s relationship with telling time began before the first written word, making it a challenge today to investigate the origin of many timekeeping units. However, some time measurement units ...

THE history and development of time measurement have already been described in a Science Museum Handbook ("Time Measurement", Part 1). The second part of the handbook which has recently been issued ...
