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 […]
A pound is a pound is a pound, right? Luckily, when you buy something in the United States, you can be extremely confident that you are getting the quantity you paid for, whether it’s a […]
NIST has recently made substantial improvements to its Johnson-noise thermometry system, which is playing a vital role in the worldwide effort to determine the value of a key physical constant in time for the impending […]
A high-tech version of an old-fashioned balance scale at the National Institute of Standards and Technology (NIST) has just brought scientists a critical step closer toward a new and improved definition of the kilogram. The […]
Dr Kibble worked at the National Physical Laboratory (NPL) from 1967 to 1998 as an experimental physicist. He was instrumental in reshaping the International System of Units (SI), and is best known for his conception […]
