Vatican City
The name was first used in the Lateran Treaty, signed on 11 February 1929, which established the modern city-state. The name is taken from Vatican Hill, the geographic location of the state. "Vatican" is derived from the name of an Etruscan settlement, "Vatica" or "Vaticum" meaning garden, located in the general area the Romans called "vaticanus ager", "Vatican territory".
Catholic Church and science
Scientific support continues through the present day. The Pontifical Academy of Sciences was founded in 1936 by Pope Pius XI, with the aim of promoting the progress of the mathematical, physical, and natural sciences and the study of related epistemological problems. The academy holds a membership roster of the most respected names in 20th century science, many of them Nobel laureates. Also worth noting is the Vatican Observatory, which is an astronomical research and educational institution supported by the Holy See.
