Outliers are values that don’t “fit in” with the rest of the data. These extreme values are commonly considered a nuisance when we seek to summarize the data with our descriptive statistics. This article will show how to turn these nuisances into useful information.
The earliest statistical tests…

Many industries, from aerospace to medical device manufacturing, are required to show customers, auditors, or regulatory bodies that their measurement devices are acceptable for use. But how do you prove that?
One of my clients needed to show the Biomedical Advanced Research and Development…

Each type of part presents its own set of inspection challenges. This is especially true for sheet metal parts that are made of various entities, each with different positioning and dimensioning tolerances, and variable thickness gauges and sizes. These features can be inherently laborious to…

Machinists working strictly in metalworking shops don’t have many occasions to gage the thickness of soft materials. But many of our readers work in supporting roles, helping to build or maintain the machines that produce textiles, plastic films, paper, and other products that are compressible.…

The collapse of Baltimore’s Francis Scott Key Bridge in March 2024 was the consequence of a long-standing problem: the fragility of aging infrastructure. As reconstruction gets underway on an estimated four-year timeline, the disaster reflects the urgent need for better bridge inspection nationwide…

If you’ve heard or read about quantum mechanics, you may have seen it described as “weird.” Even the great Albert Einstein—one of the founders of quantum mechanics—called certain aspects of the theory “spooky.”
With its wave-like particles and particle-like waves, quantum mechanics certainly…

Every time you squeeze toothpaste onto your toothbrush, spray perfume on your skin, or swallow a pill, you’re using the result of a carefully crafted recipe made in a lab. These are called formulations.
Formulations aren’t just simple mixtures—they’re complex arrangements of ingredients designed…

In last month’s article, “ANOVA and the Process Behavior Chart,” we saw how both techniques use the same basic comparison to answer completely different questions. Here, we’ll look at a case history where both techniques were used.
A physical property of a mass-produced item was important to its…
NIST
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. By monitoring how these giant “Rydberg” atoms interact with heat in their environment, researchers can…

Without us realizing it, metrology and its associated standards and services play a big role in our daily lives. We buy groceries that are weighed or measured. Prepackaged products are weighed or measured during production. Medicine at the pharmacy is measured to make sure it contains the right…

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.

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.
MIT chemical engineer Zachary Smith wants to…

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. This break in communication set off a frantic search for the tourist submersible and five passengers on…

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.
We help ensure that these units of measure are consistent across our watches and our grocery scales. But this isn’t as…

The need for long-range height measurements has been around since the principles of layout work became a fundamental requirement in machine shops.
The first step in the manufacturing process is to lay out a piece by transferring a design or pattern to a workpiece. This is performed in almost all…

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? Astronomers all over the world use telescopes to cast their gaze into space.
However, it’s not…

Compliance with industry regulations and standards is a fundamental part of medtech. Without proper medical device compliance, companies risk patient harm, litigation, and reputational damage.
Fortunately, compliance with medical device regulations and standards is not an impossible task. A…
