Where did Evangelista Torricelli grow up?

Evangelista Torricelli was born on October 15, 1608, in Faenza, province of Ravenna, Italy, and grew up in a humble family. His parents were Gaspare Torricelli, a textile worker, and Caterina Angetti.

Which scientific instrument is Evangelista Torricelli credited with inventing in 1643?

Although Torricelli is credited with inventing the first instrument for measuring the pressure of the atmosphere (the barometer), his discovery was accidental in part. He was primarily interested in creating a vacuum, and in 1643, he filled a 4-foot-long narrow glass tube with mercury and inverted it into a dish.

Why did Evangelista Torricelli use mercury?

Torricelli surmised correctly that the mercury rose in the tube because of the weight of the atmosphere pressing down on the mercury in the dish, and that the space above the mercury column was a vacuum. Both Plato and Aristotle thought the existence of a vacuum to be impossible, against Nature.

Who invented barometer?

Why mercury is used in barometer?

Mercury is employed in the barometer because its density is sufficiently high for a relative short column to be obtained. and also because it has very small vapour pressure at normal temperature. High density scales down the pressure head(h) to repesent same magnitude of pressure in a tube of smaller height.

What is Torricelli’s U-tube?

…the Italian physicist and mathematician Evangelista Torricelli, and still in use today, is a U-tube that is sealed at one end (see Figure 1B). It may be filled with liquid, with the sealed end downward, and then inverted. On inversion, a negative pressure may momentarily develop at the top of….

What college did Torricelli go to?

Torricelli entered a Jesuit College in 1624 and studied mathematics and philosophy there until 1626. It is not entirely clear at which College he studied, with most historians believing that he attended the Jesuit College in Faenza, while some believe that he entered the Collegio Romano in Rome.

Who was Giacomo Torricelli?

Torricelli came from a very poor family but was cared for and educated by his uncle Giacomo, a Camaldolese monk. In 1626, his uncle sent him to study with Benedetto Castelli, a Benedictine monk who was a friend and student of Galileo and a well-known scientist.
