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.

Seeing Beyond the Human Eye

Technology defies the boundaries of human perception. From photomicrography to astrophotography, size and distance are no longer barriers, and through slow-mo and timelapse, we are allowed to see time and humanity in a new light. Through our curiosity and thirst for the unknown, the beauty of the universe can now be explored beyond the limits of the naked eye.

A lovely film showing some of Escher's finest work, slowly to creepy music- a special treat is at the beginning of "part 3"- a very brief look at Escher in his studio just a while before he died, drawing, carving a block, printing...a rarity screenshot from 16mm- enjoy!
