Nora
Ancient city, southwest of Cagliari, Sardinia. Ruins from the 7th cent. BC indicate that the site was first settled by Phoenicians. It was the capital of Sardinia after the Roman annexation in the 1st cent. AD. Excavations have revealed a wealthy imperial Roman city with a theater, an aqueduct, a temple of Juno, a nymphaeum, and private villas overlying a typical Phoenician port.


nova
Any of a class of stars whose luminosity temporarily increases by several thousand up to a million times normal. Most appear to be binary stars, one of which is a white dwarf star drawing in matter from the other until it becomes unstable, causing an outburst in which the outer layer of material is shed. A nova reaches maximum luminosity within hours after its outburst and may shine intensely for several days or even a few weeks; it then slowly returns to its former level. Stars that become novas are usually too faint to see with the unaided eye until their sudden increase in luminosity, sometimes great enough to make them readily visible in the night sky. To observers, such objects may appear to be new stars; hence their name (Latin for "new"). See also supernova.


botany
Branch of biology that deals with plants, incl. the study of the structure, properties, and biochemical processes of all forms of plant life, as well as plant classification, plant diseases, and the interactions of plants with their physical environment. The science of botany traces back to the ancient Greco-Roman world but received its modern impetus in Europe in the 16th cent., mainly through the work of physicians and herbalists, who began to observe plants seriously to identify those useful in medicine. Today the principal branches of botanical study are morphology, physiology, ecology, and systematics (the identification and ranking of all plants). Subdisciplines include bryology (the study of mosses and liverworts), pteridology (the study of ferns and their relatives), paleobotany (the study of fossil plants), and palynology (the study of modern and fossil pollen and spores). See also forestry, horticulture.
