Scientific Contributions
Robert Darwin provided the first empirical evidence that small eye movements are made even when people attempt to keep them fixed. This he found during his studies of the afterimages of colored stimuli in which he noticed that while a person tried to fixate a colored circle, a lucid edge appeared on the adjacent white-paper background. He concluded "as by the unsteadiness of the eye a part of the fatigued retina falls on the white paper".

Famous quotes containing the word scientific:
“In the domain of Political Economy, free scientific inquiry meets not merely the same enemies as in all other domains. The peculiar nature of the material it deals with, summons as foes into the field of battle the most violent, mean and malignant passions of the human breast, the Furies of private interest.”
—Karl Marx (1818–1883)
