Historical dimensions for the cubit are provided by scripture and pyramid documentation. Additional dimensions from the Middle East are found in other early documents. Two major dimensions emerge from a history of the cubit. The first is the anthropological or short cubit, and the second is the…

You run a manufacturing business, so you know how it goes. The cost of doing business and manufacturing product never decreases. You know that your revenue must increase just to keep up. You also know that merely maintaining your revenue status quo will only ensure you get your lunch eaten by…

Much like your attic, garage or basement, the NIST archives are home to quite a number of arcane objects of unclear origin and purpose. We periodically collect these victims of misplaced paperwork and present them in a series we call “Unidentified Museum Objects.” We invite you to put on your…

Surface appearance can change your perception of color. Think of a glossy magazine. If the light is shining directly on the page, you may need to tilt the magazine and change the reflection angle to clearly see the colors. Likewise, a textured surface may appear to be a different color than a…

Modern 3D laser confocal scanning microscopes can resolve fine surface-topography detail as minute as a few nanometers, quickly and easily. It is the solution that advanced manufacturing industries turn to for efficient quality assurance surface inspections.
The changing needs of surface and…

You can’t see well without lenses that can focus, whether those lenses are in your eye or the microscope you peer through. An innovative way to focus beams of neutrons might allow scientists to probe the interiors of opaque objects at a size range they were blind to previously, allowing them to…

Invented in 1987 and commercially available since 1991, laser trackers have long been a mainstay of the aerospace industry. Automotive manufacturers have also adopted laser trackers for quality control (QC) and design. The fact is, any industry dealing with large-scale measurements—from small…

A decade before an iceberg shattered the hull plates of the Titanic and half a century before a plague of brittle fractures started sinking Liberty ships during World War II, scientists in the United States and France had devised a novel, and strikingly simple, method for measuring the way metal…

To control color, you need to be able to compare very small differences, determine their impact and understand how to address that impact. In this series we’ve already looked at the history of color analysis and the role of light in tolerancing. Here we’ll discuss the difference between a color…

In our March 30, 2018, episode of QDL, we discuss the gig economy, metrology training, and psychobabble (you know who I mean).
“Are You (and Your Company) Ready for the Gig Economy?”
More and more employees are joining the gig economy. What does that mean for your company?
“Taking on the…

Being from Colorado, I’m a big fan of winter sports: skiing, skating, snowboarding, hockey, bobsledding, and even curling. Like many people, I look forward to the Winter Olympics every four years.
The Olympics are a test of the world’s greatest athletes’ skills—skills they have spent their entire…

In 2013, the Coordinate Metrology Society (CMS) launched the first level-one certification for 3D portable measurement professionals. Since that time, the organization has consistently rolled out additional assessments to support the industry. This year is no different. The CMS has announced plans…

Tight-tolerance part inspection, whether for industrial applications or national laboratory requirements, is generally performed using cartesian coordinate measuring machines (CMMs). High-data density measurement sets to characterize part geometries are achieved using tactile probing or dynamic…

More than 30 years ago, a group of professionals formed an organization known today as the Coordinate Metrology Society (CMS). Their overall objective was to standardize the industry in terms of tooling and processes and share knowledge to educate and improve the future workforce. Some of these…

As the world heads into the fourth industrial revolution, we are still struggling with skills gaps and workforce shortages in the metrology industry. These skills are critical not only to manufacturers and scientists, but to virtually all growth sectors around the world. Taking a fresh look at how…

I am a scientist. I am often wrong, and that’s OK.
You may have heard about major errors in science and engineering that made the news headlines, like the collapse of the Tacoma Narrows Bridge, aka “Galloping Gertie,” or the 1999 crash of the Mars Climate Orbiter. Or maybe you’ve seen the recent…

In part one of this article, we explored how Woodland Trade Co. (WTC) leveraged high-accuracy portable CMMs to help land tight-tolerance aerospace contracts, and even earn Boeing’s Supplier of the Year award. Here in part two, WTC’s QA manager William Shanks reveals the advanced technology that…

In our March 16, 2018, episode of QDL, we looked at universal basic income, management status quo, ISO 10018, and how a community college is teaching cutting-edge metrology skills.
“Public Split on Basic Income for Workers Replaced by Robots”
Gallup asks Americans if they would support a universal…

Fear. Anxiety. Stress. Anger. Not exactly the emotions we’re hoping to invoke in our employees, right? Not exactly the key to motivational management, anyway.
Unfortunately, those are the emotions many people feel when it’s time to discuss their work metrics. Employees dread the idea of their…

On February 14, 1929, gunmen working for Al Capone disguised themselves as police officers, entered the warehouse of a competing gang, and shot seven of their rivals dead. The St. Valentine’s Day Massacre is famous not only in the annals of gangland history, but also in the history of forensic…

The National Institute of Standards and Technology (NIST) is home to one of the most sensitive machines in the world for measuring objects’ dimensions. Customers who rely on the instrument include the military, academia, instrument manufacturers, private industry calibration labs, and more.…

Manufacturing activities have strong ties to economic prosperity. Deloitte’s 2016 Global Manufacturing Competitiveness Index states, “Nations and companies are striving to advance to the next technology frontier and raise their economic well-being.” It’s no surprise that the manufacturing sector is…

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 to make the Moon even more reliable with a new project to measure its…

Researchers at the National Institute of Standards and Technology (NIST) have invented a new approach to testing multilayered, 3D computer chips that are now appearing in some of the latest consumer devices. The method may be the answer the semiconductor industry needs to quickly assess the…

When your public motto is “staying on the cutting edge of technology,” you’ve set a bar for yourself. Thomas Paquin set that bar when he founded Laser Specialists Inc. (LSI) in 1986. Paquin’s untimely death in 1993 left the company with questionable leadership and direction. In 2004, Nick and Jon…
