The Jastrow illusion is an optical illusion discovered by the American psychologist Joseph Jastrow in 1889. In this illustration, the two figures are identical, although the lower one appears to be larger. The short edge of the upper figure is compared to the long side of the lower one.
Famous quotes containing the word illusion:
“I hadn’t an illusion in my handbag
About the people being better there
Than those I left behind. I thought they weren’t.
I thought they couldn’t be. And yet they were.”
—Robert Frost (1874–1963)
