stroboscope etymology

Etymology: - Greek strobos ("whirling") + skopein ("to see")

Meaning and Origin: A stroboscope is a device that emits flashes of light at regular intervals. It was invented in 1832 by the Belgian physicist Joseph Plateau, who used it to study the apparent motion of objects by creating the illusion of movement from a series of still images.

The term "stroboscope" was first coined by Plateau in his 1832 paper, "Sur quelques propriétés de la persistance des impressions lumineuses sur la rétine" (On some properties of the persistence of luminous impressions on the retina). In this paper, Plateau described his device as an instrument that could "make visible the successive phases of a movement" by illuminating the object at regular intervals.

The name "stroboscope" reflects the device's ability to "whirling" or rotating, as it uses a spinning disk with cutouts to create the flashes of light. The word "skopein" ("to see") indicates that the device is used for observation.
