The National Institute of Standards and Technology (NIST) has filed a provisional patent application for a microflow measurement system, about the size of a nickel, that can track the movement of extremely tiny amounts of […]
Future communications networks that are less vulnerable to hacking could be closer to reality with an invention that measures the properties of single-photon sources with high accuracy. Built by scientists at the National Institute of […]
Studio photographers may be familiar with the 1,000-watt quartz halogen lamps known as “FELs.” Scientists use them too—specially calibrated ones, at least—to test the performance of light sensors that monitor Earth’s weather, plant life and […]
Paving the way for transforming the world’s measurement system, an international task force has determined updated values for four fundamental constants of nature. The updated values comprise the last scientific piece of the puzzle for […]
The “inconstant moon,” as Shakespeare called it in Romeo and Juliet, is more reliable than his pair of star-crossed lovers might have thought. Now researchers at the National Institute of Standards and Technology (NIST) plan […]
Using a state-of-the-art device for measuring mass, researchers at the National Institute of Standards and Technology (NIST) have made their most precise determination yet of Planck’s constant, an important value in science that will help […]
March 29, 2017 – Most people have never seen an accelerometer — a device that measures change in velocity — and wouldn’t know where to look. Yet accelerometers have become essential to modern life, from […]
Last year, upwards of 25 trillion cubic feet of natural gas were delivered to customers in the United States, and when it changed hands, nearly every cubic foot was measured using gas flowmeters. The accuracy […]
