Google sometimes remembers a particular person's birthday or death anniversary and changes their doodles in his memory. In such a situation, Today's Google Doodle celebrates Belgian physicist Joseph Antoine Ferdinand Plateau, inventor of the phenakistiscope, a device that led to the birth of cinema by creating the illusion of a moving image.

At the same time you may be aware that Phenakistiscope created the illusion of a moving image that was very useful for the birth and development of a motion picture. Plateau's father was an artist who left everyone behind in making paintings with flowers. Plateau studied law in the early stages but later studied physiological optics, especially emphasizing the effect of light and color on the human retina, which made him one of the most famous scientists of the 19th century. With this, it is said that his research was focused on how pictures are formed on the retina, given their correct duration, color and intensity.

He then built a stroboscopic device based on these findings in 1832, fitted with two discs that rotated in opposite directions. One disc was filled with small windows, evenly spaced in a circle, while the other had a series of pictures of a dancer. When both discs turned at exactly the right speed, the images seemed to merge, creating the illusion of a dancer in motion. You can see it in Google Doodle also.
