Circular motion

James Maxwell was the first to realize that light is able to travel in perfect circles within the fish-eye lens because the density of the lens changes, with material being thickest at the middle and gradually thinning out toward the edges. Source: MIT


Mostly we see light travel straight
In a glass of water,
the spoon bends
we know refraction

Three motorists in a
cage
circular motion

Through a fish eye
lens
light too experiences
circular motion
