Numéro d’image : 11830267
| John Napier. Portrait of the Scottish mathematician John Napier (1550-1617),the discoverer of logarithms. Napier came from a landed family and so was educated in France and at St. Andrews in Scotland. He studied mathematics as a hobby and he published his first logarithm tables in 1614,in the process of which he developed decimal notation. For the tables he chose the transendental number e (approximately 2.717) as the base. These Napierian,or natural,logarithms are most relevant to exponential systems. His logarithms greatly helped Kepler in his calculations of planetary motion. This artwork is from a book published in 1833 | |
