They achieved this by utilising the phenomena of objects moving slower and shortening in length from Einstein's theory of relativity, along with two pieces of gold foil and a micrometre screw. In ...

The Speetec is a sensor solution for moving materials in a linear path and special processes. With the Speetec, Sick is expanding its product range for speed and length measurement of objects moving ...

, one of the first questions you’ll be asked is: What’s your draw length? If you’re not sure, don’t worry, because the basic procedure for how to measure draw length is super simple: You just hold ...

Once upon a time, I was involved in an abortive attempt to measure the variation of the fundamental constants. Thanks to that experience, I’ve always had an interest in these measurements, so a new ...
