1955年5月15日是俄罗斯伟大生物学家伊里亚·伊里奇·梅契尼科夫诞生110周年的纪念日。梅契尼科夫科学兴趣之多种多样是令人惊奇的。他是比较病理学、进化胚胎学、微生物学和免疫学的奠基人之一。梅契尼科夫确定了无脊椎动物和脊椎动物胚胎发育中的一般特征,同时和另一个俄罗斯科学家 O.科瓦列夫斯基一道建立了实验形态学。他的几本阐明哲学问题的书:“论人性短文集”,“合理世界观探求四十年”和“乐观主义短文集”是世界闻名的。 May 15, 1955 is the anniversary of the 110th anniversary of the birth of the great Russian biologist Ilya Ichicar Mechnikov. The wide variety of scientific interests in Mechnikov is surprising. He is one of the founders of Comparative Pathology, Evolutionary Embryology, Microbiology and Immunology. Mechnikov identified common features in the development of invertebrates and vertebrates embryos and established experimental morphology with another Russian scientist, O. Kovalovsky. His books on elucidating philosophical issues are world famous, “On the Collection of Human Nature,” “Searching for a Rational World Outlook for Forty Years,” and “The Essay on Optimism.”
