MIT’s Computer Science and Artificial Intelligence Lab has figured out a way of measuring walking speed to within 95 and 99 percent accuracy — all without requiring a wearable or other on-body ...

You might think that if you have a need to measure the speed of a projectile that is too fast for your high-speed camera, you would have to invest in some significantly expensive equipment. That was ...

The motion of any object is relative. On Earth we tend to ignore that, because the vast background of the ground gives us a seemingly fixed and absolute frame of reference. Sitting comfortably at our ...

Wind speed measurement has long been a cornerstone of meteorological observation, renewable energy assessment and aeronautical research. The performance of anemometers—devices designed to accurately ...

Corrections & clarifications: A previous version of the story misstated a measurement of Internet speed. We know what “slow” internet is like: videos buffer, downloads lag and a single page can take ...

No boat is perfectly symmetric or at maximum/minimum tolerances when you first purchase it. The closer you can get it to perfect, the better it will sail. To begin, you need to take some accurate ...

Are general purpose internet speed tests (generally HTTPS speed) a good or poor indication of ' wireless internet performance '? Are they just too crude to give a realistic appraisal of real WLAN ...

While a large number of resin and metal materials demonstrate plastic deformation behavior, ceramic and glass materials exhibit almost no plastic deformation. Rather, they are prone to brittle failure ...
