Scientists from the National Institute of Standards and Technology (NIST) are developing a mass balance to measure miniscule amounts of liquid with much higher
Static force, such as the weight of a person standing motionless on a bathroom scale or the force that an office full of equipment exerts on a high-rise floor
Researchers at the National Institute of Standards and Technology (NIST) have designed and built an optical device that could set a new standard for measuring
Mechanical engineers at the National Institute of Standards and Technology (NIST) have just finished calibrating several dozen large metal masses, which will be
Researchers at the National Institute of Standards and Technology (NIST) have conducted the first demonstration of a faster and more accurate way to calibrate
The Pilot Study — read 2016 article details — was completed in late 2016 and the Final Report was published on the BIPM website (PDF) in June of 2017. The main
A decade before an iceberg shattered the hull plates of the Titanic and half a century before a plague of brittle fractures started sinking Liberty ships during
Accelerometers — devices that measure change in velocity — are built into automobiles, airplanes, cell phones, pacemakers, and scores of other products
When the kilogram, the world’s basic unit of mass, gets a new definition in 2018, it will be based not on a physical artifact but a constant of nature. However
Photons are bizarre: They have no mass, but they do have momentum. And that allows researchers to do counterintuitive things with photons, such as using light
The last few bolts were tightened just weeks ago – by hand. Now fully restored, NIST's 4.45 meganewton (one million pounds-force) deadweight machine – the
It's official: NIST's 4.45-million newton (equivalent to one million pounds-force) deadweight machine – the largest in the world – is back in one piece after a
They activate airbags. Keep aircraft correctly positioned in flight. Detect earthquakes or sudden vibrations in failing machinery. Guide military hardware
What if doctors could deliver anti-cancer drugs directly to tumors without making patients sick? Bringing this dream of targeted drug delivery closer to reality
Restoration is well underway for NIST's 4.45-million newton (equivalent to one million pounds-force) deadweight machine, the largest in the world. The three
In a few weeks, NIST will begin offering a new, state-of-the-art calibration service for accelerometers. Based on a technique called laser interferometry, the
For the first time in half a century, NIST's 4.45-million newton (equivalent to one million pounds-force) deadweight machine – the largest in the world – is
It might seem that when the world agrees on a new definition of the kilogram based on a fixed value of a physical constant, as is expected soon, no one will
Few substances are tracked more closely and stored more carefully than the nuclear waste produced at power plants and elsewhere. So the properties of the large
Randy Wagner and the rest of the Acoustics Team in PML's Semiconductor and Dimensional Metrology Division are planning new research directions as they celebrate
