摘要:

An assessment is given of John Herschel's overall contributions to nineteenth century astronomy. John Herschel built on his pioneering father William Herschel's foundations, with revisions and extensions to the southern hemisphere. His work, incorporated into his general treatises on astronomy, had a major influence on the direction of astronomical progress.

摘要:

The scientific work of Sir John Herschel during his visit to the Cape in 1834–38 is described. An analysis is made of Herschel's general survey of the southern sky, his reason for carrying it out and the instrumentation and techniques that he employed. Herschel's special studies of Halley's comet, the satellites of Saturn, bright nebulae and stellar photometry are discussed. Herschel's participation in the Cape scientific and social activities is described.

摘要:

In this paper I shall present a sketch of the life and contributions to science of Sir John F. W. Herschel (179–1871). One of the theses that I shall develop is that John Herschel can meaningfully be described as Britain's first modern physical scientist. In addition to developing this thesis, I shall make some remarks about lesser known aspects of Herschel's life.

摘要:

John Herschel's interest in botany was stimulated by his contact with the species-rich Cape flora while resident in Cape Town, 1834–1838. The comparative study of his extensive living collection of bulbous plants, mainly of the Iridaceae, Liliaceae, Amaryllidaceae and Orchidaceae led him to consider some basic aspects of the origin of species and of taxonomic theory, in letters to colleagues in Europe. He also conducted simple experiments on breaking dormancy in hard-coatedLeucadendronseeds by heat-scarification. Herschel's portfolio of over 131camera lucidadrawings of Cape plants, finished in watercolours by his wife, is enumerated and discussed.

摘要:

John Herschel's use of the camera lucida as a drawing aid and the part played by this instrument in Henry Fox Talbot's motivation to invent photography are described. Herschel's seminal contributions to the early progress of photography, his attempts at colour photography, his invention of the “blueprint” process and his assistance to other photographic pioneers are discussed.

摘要:

During his four years at the Cape of Good Hope in the mid—1830s, Sir John Herschel became very involved in a major scheme to restructure the fragmented and largely ineffectual education system of the Colony. The result was the establishment, soon after his departure in 1838, of one of the earliest and best structured state education systems in the world.
