When are two nominally identical kilogram masses no longer identical? When each goes to a different place and adsorbs varying amounts of moisture and...
When a jackhammer starts pounding outside your window at 7 o’clock on a Monday morning, you might find it annoying. For the worker who is running that...
The Pilot Study — read 2016 article details — was completed in late 2016 and the Final Report was published on the BIPM website 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...
