The speed of light is a fundamental constant, approximately 299,792,458 meters per second. It's the same for all observers and hasn't changed measurably over billions of years. Nothing can travel ...

In 1676, by studying the motion of Jupiter's moon Io, Danish astronomer Ole Rømer calculated that light travels at a finite speed. Two years later, building on data gathered by Rømer, Dutch ...

The health of cells is maintained, in part, by two types of movement of their nucleoli. This dual motion within surrounding fluid, it reports, adds to our understanding of what contributes to healthy ...

Slo-mo is one of the coolest features of the iPhone camera. By filming at a high frame rate and then playing back the footage at a lower frame rate, the slo-mo creates emphasis on a few frames in the ...

Monitoring takes the form of sensors and intelligent devices connected to a digital processor. These monitored values are used for computing and then controlling some sort of real-world action. Many ...

High-speed CMOS image sensors are available in several types for a variety of markets, for use in general purpose, high end or custom high-speed cameras. Such cameras can be used for applications like ...

Engineers developed a ping-pong-playing robot that quickly estimates the speed and trajectory of an incoming ball and precisely hits it to a desired location on the table. MIT engineers are getting in ...

This is the first of a two-part series. Part 2 can be found here. Encoders play an integral role in almost every mechanical system that involves motion monitoring or control. There are a variety of ...

Ever wonder what it'd look like if you drove into a speed bump at full speed rather than slowing down? Wonder no more, because the folks from the Warped Perspective YouTube channel went and found out ...
