Technology has improved the scientific community’s ability to measure in many ways that our ancestors would have trouble believing. From obtaining measurements across galaxies down to the tiniest of ...

In fields from electronic design to industrial and pharmaceutical manufacturing, precision testing and measurement have long been critical features, measuring pressure as sensitive as a baby’s breath ...

I have a low tolerance for precise inaccuracy, though I’ve been in such situations more often than I care to admit. The upside is that it’s like an epiphany when awareness hits (or someone hits me ...

Figure 1 shows that individual measurement values hover around a mean value and the difference between the mean value and true value is the systematic error of ...

Optical clocks are highly precise timekeeping devices that measure time by tracking the oscillations of light, as opposed to ...

Scientists from the University of Rochester and UC Santa Barbara have built a laser so small it can sit on a penny. But don’t let its size fool you. This tiny laser could power the next generation of ...

This article is the second in the PRTD (platinum resistance temperature detector) application series. (Part 1 can be found here.) It explains how to achieve precision, wide-range temperature ...

Purpose: The precision and accuracy of two blood glucose meters were evaluated using finger and forearm blood samples. Methods: Duplicate blood glucose measurements on the same forearm and finger as ...
