| 词汇 | lambert |
| 词源 | lambert. The son of a poor tailor and largely self-educated, Johann Heinrich Lambert nevertheless managed to win fame as a physicist, philosopher, mathematician, and astronomer. The German scientist, though he died of consumption in 1777 when only 49, made important discoveries in many fields. In mathematics Lambert proved the irrationality of pi and devel- oped several trigonometry concepts, while in philosophy his Neues Organon (1764) pointed out the importance of begin- ning with experience and using analytical methods to prove or disprove theories. Lambert also made valuable contributions in electrical magnetism, mapmaking, and meteorology; several theorems in astronomy bear his name. It is for his work in physics on the measurement of light intensity and absorption that his name is honored in the dictionaries, the lambert being the unit of brightness in the metric system. |
