In this role he solved some of the great mathematical problems of the day, such as finding a cycloid’s area and center of gravity. Our editors will review what you’ve submitted and determine whether to revise the article.Two years later, pursuing a suggestion by Galileo, he filled a glass tube 4 feet (1.2 m) long with After Galileo’s death on January 8, 1642, Grand Duke Ferdinando II de’ Medici asked him to succeed Galileo as the grand-ducal mathematician and professor of mathematics in the University of Pisa.

An aneroid barometer "registers the change in the shape of an evacuated metal cell to measure variations in the atmospheric pressure."



In 1641, Evangelista Torricelli moved to Florence to assist the astronomer It was Galileo that suggested Evangelista Torricelli use mercury in his vacuum experiments.

In 1626 Torricelli went to Rome to study sciences and then later wrote a thesis on the path of projectiles. Torricelli filled a four-foot long glass tube with mercury and inverted the tube into a dish.







He was the first person to create a sustained vacuum and he invented the barometer.

Biography - Evangelista Torricelli Evangelista Torricelli was born October 15, 1608, in Faenza, Italy and died October 22, 1647, in Florence, Italy.

Although Galileo promptly invited Torricelli to visit, he did not accept until just three months before Galileo’s death. Evangelista Torricelli, an Italian mathematician and scientist, questioned that assumption, and proposed that the air had weight, and that it was the weight of the air (not the attractive force of the vacuum as many thought) which held (or rather, pushed) up the column of water. Aneriod means fluidless, no liquids are used, the metal cell is usually made of phosphor bronze or beryllium copper.​A barograph is an aneroid barometer that gives a continuous reading of atmospheric pressures on graph paper.

Danach duldete die Natur kein Das folgende Zitat aus einem Brief an seinen Freund zeigt einen Erklärungsversuch TORRICELLIs für sein berühmtes Experiment mit Quecksilber.
Torricelli was born to a poor family in 1608 and to make matters worse, his father passed away when Torricelli was just a child. Evangelista Torricelli (October 15, 1608 – October 25, 1647) was an Italian physicist and mathematician, best known for his invention of the barometer.





Nach dem Besuch einer Jesuitenschule in Faenza wurde TORRICELLI im Jahr 1626 nach Rom geschickt.

)Torricelli’s statue in the Museo di Storia Naturale di Firenze.Aside from several letters, little is known of Torricelli’s activities in the years between 1632 and 1641, when Castelli sent Torricelli’s monograph of the path of projectiles to Galileo, then a prisoner in his villa at Arcetri. Evangelista Torricelli was born October 15, 1608, in Faenza, Italy and died October 22, 1647, in Florence, Italy. In 1624 he entered the Jesuit College of Faenza, then moved on to the Collegio Romano in Rome.
