The Stopped Clock Illusion

Chronostasis (from Greek χρόνος, chrónos, “time” and στάσις “standing”) is the illusion in which the first impression following a saccade (quick eye movement) appears to be extended in time. The most well-known version of this illusion is the stopped-clock illusion, where the first movement of the second hand of an analog clock, following the viewer’s directing attention to the clock, appears to take longer than the next movement. When eyes execute a saccade, perception of time stretches slightly backward. The viewer’s brain registers that they have been looking at the clock for slightly longer than they really have, producing the illusion that the second-hand is frozen for more than a second. Although this happens every time the eyes move from one fixation point to the next, it is rarely noticed. One explanation is that the brain is filling in the gap while the eyes move from looking at one thing to the next.

Periscope Photos

It was interesting watching movies like down periscope & such kind of naval movies wherein they show the whole action is based on what they see through the periscope. Always wondered whether we could ever have a true periscope view & came across this collection. Here we have some interesting periscope photos. LINK
