NMR titration studies in acetonitrile-d(3)/DMSO-d(6) mixtures demonstrate that diindolylurea-based receptors can form complexes with the organophosphorus nerve agent soman in organic solution.
It has been alleged that Carolus Linnaeus practised Eurocentrism, sexism and racism in naming plant genera after famous botanists, and excluding 'barbarous names'. He has therefore been said to practise 'linguistic imperialism'. This paper examines whether Linnaeus applied 'linguistic imperialism' to the naming of Chinese plants. On the basis of examples such as Thea (¼Camellia), Urena, Basella, Annona, Sapindus (¼Koelreuteria), and Panax, I conclude that Linnaeus used generic names of diverse origins. However, he misidentified Chinese plants' habitats, and acted on these misapprehensions.
Fellows of The Royal Society have been concerned with the definition and measurement of time from the first days of the Society. John Flamsteed, F.R.S., ‘Royal Astronomer’, showed that the rotation of the Earth was isochronous and that the length of the solar day varied with the season because the path of the Earth about the Sun was an ellipse inclined to the Equator of the Earth. In the 20th century, D.W. Dye, F.R.S., made quartz oscillators that replaced mechanical clocks, and L. Essen, F.R.S., brought into use at the National Physical Laboratory the first caesium beam frequency standard and advocated that atomic time should replace astronomical time as the standard. The Society supported the development of chronometers for use at sea to determine longitude, and Fellows used the electric telegraph to find longitude in India. Edmond Halley, F.R.S., estimated the age of the Earth from the saltiness of lakes and seas; Lord Kelvin, F.R.S., estimated the rate at which energy was being radiated from the Sun; and Lord Rutherford, F.R.S., showed how the ages of rocks and of the Earth could be found from decay of radioactive minerals in them.
In 1766 Jean-Jacques Rousseau, in exile from France and Switzerland, came to England, where he made the acquaintance of Margaret Cavendish Harley Bentinck, Duchess of Portland. The two began to botanise together and to exchange letters about botany. These letters contain salient statements about Rousseau's views on natural theology, gardens, botanical texts and exotic botany. This exchange entailed not only discussions about plant identifications and other botanical matters, but most important, reciprocal gifts of books and specimens in the manner of gentlemanly scientific correspondence of the period. Rousseau volunteered his services as the Duchess's 'herborist' or plant collector, and collected specimens and seeds in her behalf; these were destined for her own extensive herbaria and other natural history collections. Rousseau, who elsewhere denied female talent for science, admired the Duchess's knowledge of natural history, acknowledging his own as inferior. Their correspondence ended when the Duchess sent him the Herbarium amboinense of Georg Rumpf (Rumphius), an important work of exotic botany. Rousseau considered exotic botany to be the antithesis of the domination-free nature from which he derived solace and inspiration. r
Most Fellows of The Royal Society in the late seventeenth century knew Rome through their classical education and would have been attracted to visit it for the remains of antiquity and for the new churches and palaces of the papal city. John Evelyn, in Rome 16 years before the foundation of the Society, John Ray, Edmond Halley and Robert Nelson, and Bishop Burnet and G.W. Leibniz, also met people who had links to the Accademia dei Lincei of Prince Federico Cesi, and to the later Accademia Fisica-mathematica associated with Queen Christina of Sweden. Besides astronomy, they were especially interested in cabinets of curiosities and in Vesuvius and other volcanic sites. They met English residents in Rome, especially those around the Venerable English College.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
