In meteorology, an anemometer (from Ancient Greek άνεμος (ánemos) 'wind' and μέτρον (métron) 'measure') is a device that measures wind speed and direction. It is a common instrument used in weather stations. The earliest known description of an anemometer was by Italian architect and author Leon Battista Alberti (1404–1472) in 1450.
Leon Battista Alberti is a major character in Roberto Rossellini's three-part television film The Age of the Medici (1973), with the third and final part, Leon Battista Alberti: Humanism, centering on him, his works (such as Santa Maria Novella), and his thought. He is played by Italian actor Virginio Gazzolo.
In 1450, Leone Battista Alberti developed a swinging-plate anemometer, and is known as the first anemometer. [1] In 1607, Galileo Galilei constructs a thermoscope. In 1643, Evangelista Torricelli invents the mercury barometer. [1] In 1662, Sir Christopher Wren invented the mechanical, self-emptying, tipping bucket rain gauge.
In 1450, Leone Battista Alberti developed a swinging-plate anemometer, and was known as the first anemometer. [44] In 1607, Galileo Galilei constructed a thermoscope. In 1611, Johannes Kepler wrote the first scientific treatise on snow crystals: "Strena Seu de Nive Sexangula (A New Year's Gift of Hexagonal Snow)."
1450 – Leone Battista Alberti developed a swinging-plate anemometer, and is known as the first anemometer. [22] – Nicolas Cryfts, (Nicolas of Cusa), described the first hair hygrometer to measure humidity. The design was drawn by Leonardo da Vinci, referencing Cryfts design in da Vinci's Codex Atlanticus.
