Accurate perception of motion depends critically on accurate estimation of retinal motion speed. Here we first analyse natural image movies to determine the optimal space-time receptive fields (RFs) ...

The principle of relativity, as initially described by Galileo, posits that the laws of physics remain consistent regardless of an observer's relative motion. Einstein's special relativity ...

Scientific American is part of Springer Nature, which owns or has commercial relations with thousands of scientific publications (many of them can be found at www ...

The last 20 years have seen precision amplifiers used for positioning and velocity control make major strides in power output, size, and control features. Applications such as laboratory automation, ...

The camera app on your iPhone can capture slow-motion video in two different speeds; here's what you need to do to adjust it. Jason Cipriani Contributing Writer, ZDNet Jason Cipriani is based out of ...

Images of the cube and sphere created by the Vienna team. At rest, the cube appears normal. When simulated at 99.9% of light speed, the sphere remains round but reveals parts of its far side. (Image ...

I love the slow motion video on the iPhone 6. Not only does it record 720p video at 240 fps, it also let's you instantly adjust what part of video is in slow motion and what part is in real time. I ...

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 ...
