Legacy of the Roman Empire learned classes throughout the Middle Ages; this is especially seen during the Renaissance and Baroque periods. Books which had a revolutionary impact on science, such as Nicolaus Copernicus' "De revolutionibus orbium coelestium" (1543), were composed in Latin. This language was not supplanted for scientific purposes until the 18th century, and for formal descriptions in zoology, as well as botany - it survived to the later 20th century. The modern international Binomial nomenclature holds to this day: the scientific name of each species is classified by a Latin or Latinized name. Today the Romance languages, which comprise all languages that descended
Introduction to the mathematics of general relativity the gravitational field outside a spherical mass, on the assumption that the electric charge of the mass, the angular momentum of the mass, and the universal cosmological constant are all zero. The solution is a useful approximation for describing slowly rotating astronomical objects such as many stars and planets, including Earth and the Sun. The solution is named after Karl Schwarzschild, who first published the solution in 1916. According to Birkhoff's theorem, the Schwarzschild metric is the most general spherically symmetric, vacuum solution of the Einstein field equations. A Schwarzschild black hole or static black hole is a black hole
