If you know your U.S. history, there have been several attempts to adopt the metric system, all to no avail. It's the universal standard for most of the world and way more intuitive, yet the chances ...

A new laser-based method for measuring millimeter distances more accurately than ever before--with an uncertainty of 10 picometers (trillionths of a meter)--has been developed and demonstrated by a ...

For decades, if you wanted to make a millimeter wave spectrum analyzer measurement, you were forced to use large, heavy bench test equipment because there were no other options available. To make ...
