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:
“There is one great fact, characteristic of this our nineteenth century, a fact which no party dares deny. On the one hand, there have started into life industrial and scientific forces which no epoch of former human history had ever suspected. On the other hand, there exist symptoms of decay, far surpassing the horrors recorded of the latter times of the Roman empire. In our days everything seems pregnant with its contrary.”
—Karl Marx (1818–1883)
