Frequency combs — specialized lasers that act like rulers to measure light — are now being brought down to a low-power, chip-scale form. NIST researchers David
Introduction According to the 2021 Fact Sheet: The Bipartisan Infrastructure Deal, one in five miles of U.S. highways and major roads and over 45,000 bridges
Weights and measures inspections provide a legally required, independent validation of the accuracy of commercial weighing and measuring devices; provide a
It’s easy to learn the metric system with the SI Units Card Deck (NIST SP 1297), an interactive educational activity that helps learners build their skills
Nearly every modern cellphone has a built-in compass, or magnetometer, that detects the direction of Earth’s magnetic field, providing critical information for
Devices that capture the brilliant light from millions of quantum dots, including chip-scale lasers and optical amplifiers, have made the transition from
Chip-based devices known as frequency combs, which measure the frequency of light waves with unparalleled precision, have revolutionized time keeping, the
When testing a new medicine, researchers must do more than assess how well that drug works. They also have to determine whether the medicine has some negative
There are dedicated, enthusiastic people in this world who have made a cause (and hobby) out of saying, “I heard that.” NIST is keenly aware. We’re talking
From the minuscule bindings of molecules to the far reaches of space, we’re exploring the universe around us by catching sight of the smallest particles of
Perched atop a high plateau in Chile’s Atacama Desert, a long-awaited observatory is beginning to take shape: the largest suite of ground-based telescopes
The OWM Laboratory Metrology group operates an ISO 17043 compliant Proficiency Testing (PT) program that assesses the effectiveness of the metrology training
NIST Office of Weights and Measures (OWM) is collaborating with the National Conference on Weights and Measures (NCWM), together with 28 state and 38 local
Researchers have created a prototype quantum computer with a record number of qubits—the analog of bits in an ordinary computer—capable of performing logical
Microscopic magnetic probes that change shape in response to their environment may greatly enhance magnetic resonance imaging (MRI). However, producing the
In research, sometimes the bumpy path proves to be the best one. By creating tiny, periodic bumps in a miniature racetrack for light, researchers at the
Entanglement—a uniquely quantum phenomenon that intimately links the fate of subatomic particles even if they reside on opposite sides of the galaxy—is a key
Researchers at NIST and their colleagues have built a superconducting camera containing 400,000 pixels — 400 times more than any other device of its type.
A single-atom-thick sheet of carbon known as graphene has remarkable properties on its own, but things can get even more interesting when you stack up multiple
“Only connect” is the most famous line in the British novelist E. M. Forster’s writings. Forster was urging the readers of his book Howard’s End to make
If you’re undergoing a missile attack and that missile is above the atmosphere, the best place to destroy it is while it’s still in space. To do that, you need
