Here on land, the speed of a vehicle is recorded in either miles per hour or kilometers per hour. In either case, determining how fast you're moving on land is fairly simple because you can see ...

Current vision systems for robots and drones rely on 3D sensors that, although powerful, do not always keep up with the ...

Nuclear physicists proposed a method to measure the speed of sound characterizing matter created in nuclear collisions. Heavy nuclei consist of hundreds of protons and neutrons (belonging to a group ...

Ever wondered why automakers use 60 miles per hour as the standard measurement for acceleration? There's actually a good reason.

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 ...

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 ...

A crankshaft may experience irregular rotational speed patterns caused by a combustion engine’s discrete firing process. These excite components of the driveshaft, which causes rotational vibrations ...

It is hard to remember that a lot of high tech research went on well before the arrival of electronic computers, lasers, and all the other things that used to be amazing but are now commonplace.
