Scientists develop new primary method for measurement of pressure

Scientists from the Physikalisch-Technische Bundesanstalt (PTB) have implemented a novel pressure measurement method, partly as a byproduct of the work on the "new" kelvin. In addition to being new, this procedure is a primary ...

Light-based technologies for measurement

Metrology ― the science of measurement ― plays an essential role in advancing science and technology. Precise definitions and measurements underpin almost all scientific and technological developments, from the astrophysical ...

Video: Lisa Pathfinder mission overview

LISA Pathfinder will pave the way for future missions by testing in flight the very concept of gravitational wave detection: it will put two test masses in a near-perfect gravitational free-fall and control and measure their ...

The guide to biomolecular movie-making

High-speed atomic force microscopy (HS-AFM) is providing the means to produce dramatic footage of moving biomolecules, and scientists at Kanazawa University leading the field.

New method for imaging defects in magnetic nanodevices

Metrology

Metrology is the science of measurement. Metrology includes all theoretical and practical aspects of measurement. The word comes from Greek μέτρον (metron), "measure" + "λόγος" (logos), amongst others meaning "speech, oration, discourse, quote, study, calculation, reason". In Ancient Greek the term μετρολογία (metrologia) meant "theory of ratios".
