词汇 | daltonism |
词源 | daltonism. So determined was British scientist John Dalton (1766–1844) to solve the mystery of color blindness that he willed his eyes for study after his death. His pioneering paper, “Extraordinary Facts Relating to the Vision of Colours” (1794), is the earliest account of the problem, based on obser- vations of himself, his brother, and other similarly afflicted persons. As a result of his descriptions, daltonism became a synonym for color blindness, especially the inability to distin- guish between the colors red and green. One of the great pio- neers in science, the industrious Dalton also kept a meteoro- logical diary in which he entered 200,000 observations over 57 years. This diary both resulted in a remarkable book on weather conditions (Meteorological Observations and Essays, 1793) and contained the germs of his atomic theory, Dalton’s major scientific contribution and the basis of modern chemistry. |
