Last year marked the 100th anniversary of the death of Ernst Abbe, who passed away on January 14, 1906—just a few days short of his 65th birthday. Abbe is well known for his seminal contributions to scientific microscope construction, which include his diffraction theory for image formation, and the formulation of the sine condition and Abbe number. He was also a noted entrepreneur, astronomer and social reformer. c h}wXn

Ernst Abbe was born in Eisenach, Germany, on January 23, 1840. He spent his childhood in poverty—which perhaps explains why he was committed to social welfare for the rest of his life. After graduating from secondary school, he began his studies at the University of Jena. There, Abbe attended lectures in mathematics and physics. \)?+6D'#

Early on, his professors noted his acumen in science. Abbe won a scientific competition in his third semester and, later, he was awarded a scholarship by city officials at Eisenach. After completing two years at Jena, Abbe took up three additional years of studies at the University of Göttingen, where he attended lectures in mathematics given by Bernhard Reimann, as well as lectures in meterology, optics and astronomy.  肇州县| 晋江市| 阜南县| 镇宁| 德昌县| 嘉黎县| 义马市| 阿瓦提县| 湘潭市| 嘉定区| 藁城市| 长汀县| 平顺县| 成安县| 阿城市| 扶风县| 伊宁县| 柯坪县| 左贡县| 安宁市| 垦利县| 东方市| 通海县| 临猗县| 翼城县| 吕梁市| 汾西县| 九江县| 衡山县| 鸡东县| 青冈县| 德清县| 苍南县| 呼和浩特市| 原阳县| 湖南省| 海口市| 临高县| 呼图壁县| 涞源县| 天水市|
