It was one of the first scientific works to illustrate plants, insects and animals through the lens of a microscope. But Hooke could have scarcely imagined capturing riotous motion in the microscopic worlds he saw through his lens. Doing so is what Nikon’s Small World in Motion competitors have all accomplished, 355 years later. The yearly contest, now in its 10th year, is the technological offspring of the camera maker’s nearly half-century-old microphotography competition Small World. As imaging has evolved, so has our ability to capture the microscopic world actually moving rather than just dead and fixed to a thin sheet of glass.
