An Estimate of the Degrees of the Mortality of MankindHalley’s text may be clearer if the reader notes that he intends: .. = 1238; .. = 1000; .. = 890; .. = 855. According to Westergaard (1969, p. 34) the Breslau lists showed 1218 births in 1691, among whom 992 were alive on January 1, 1692. Rounding the figure, Halley set .. = 1000 for 1238 births.作者: 衰弱的心 時間: 2025-3-24 02:39 作者: 殘酷的地方 時間: 2025-3-24 08:28 作者: Insufficient 時間: 2025-3-24 14:17 作者: 拖債 時間: 2025-3-24 15:26
