Who is Joseph Plateau?
Joseph Plateau (1801-1883) was a physics professor at Ghent University. He discovered the (after) effects of light on the retina. Based on these findings, he invented the phenakistiscope, a device that gave the illusion of a moving image. Plateau also studied other optical phenomena, including the perception of colours and surface tension. He managed to make this subject matter intelligible by giving demonstrations. During the second half of his life, he gradually went blind.
What did Plateau use these wire frames for?
When you dip these wire frames into a soap solution, you will see soap films stretched across the wires. Joseph Plateau used them for his study of surface tension. He had originally designed a special instrument to simulate a situation in which a drop of oil is not subjected to gravity (the Plateau Tank). He later realised that he could just as well use these thin soap films for his research as they weighed next to nothing.
