In last month’s article, “ANOVA and the Process Behavior Chart,” we saw how both techniques use the same basic comparison to answer completely d
New Atom-Based Thermometer Measures Temperature More Accurately

Scientists at the National Institute of Standards and Technology (NIST) have created a new thermometer using atoms boosted to such high energy levels that they are 1,000 times larger than normal.
Laying the Perfect Wood Floor

It creates a warm and inviting atmosphere. Its natural grain and color tones have a lively effect and add character to a room. We are talking about classic wood flooring—usually laminate, and optionally with a click system for easy installation.
Designing Tiny Filters to Solve Big Problems

In his lab at MIT, Zachary Smith is designing membranes with tiny pores that can filter tiny molecules based on their size. Here, Smith holds a “membrane coupon,” which is a small piece of polymer that can filter gas molecules selectively.
For many industrial processes, the typical way to separate gases, liquids, or ions is with heat, using slight differences in boiling points to purify mixtures. These thermal processes account for roughly 10% of the energy use in the United States.

On June 18, 2023, the Titan submersible was about 90 minutes into its two-hour descent to the Titanic wreckage at the bottom of the Atlantic Ocean when it lost contact with its support ship.
Talk NISTy to Me

Right now, the U.S. and Germany have different approaches to defining, or realizing, as the researchers call it, the kilogram. Here, NIST researcher Darine Haddad looks on as German researcher Beatrice Rodiek places a sphere on NIST’s highly accurate weighing machine, known as the Kibble balance. The goal of the research is to get closer to the same definition using the different methods. Credit: B. Hayes/NIST
NIST is unique as the national measurement science institute. We are the U.S. agency responsible for maintaining measurement standards, from the second to the kilogram.
Scribing for New Heights

Our solar system has fascinated mankind for thousands of years. Astronomical research is looking for answers to the big questions of human existence. How big is the universe? How did it come into being?
