Evangelista Torricelli – Wikipedia

In he created a tube approximately one meter long, sealed at the top, filled it with mercury, and set it vertically into a basin of mercury.

Torricelli’s experiment

The barometer is then placed inverted on the dish full of mercury. Pump makers of the Grand Duchy of Tuscany attempted to raise water to a height of 12 meters or more, but found that 10 meters was the limit with a suction pump as recounted in Galileo’s Dialogue.

El elemento sensor del nuevo instrumento era un diafragma corrugado en acero fijo alrededor de toda su periferia. In exchange he worked for him as his secretary from to as a private arrangement.

It is supposed by some to have led to the idea of ve “completed infinity”. It is almost certain that Torricelli was taught by Castelli.

Its appearance in the European market, following by that in America, became a starting point for the gradual but firm replacement of the by then very usual mercury manometer through an element that worked based on a different baarometro principle.

Although there seems no room for doubt that Torricelli’s was arrived at independently, the matter was still in dispute up to his death.

Its communication by Torricellk to Galileo inwith a proposal that Torricelli should reside with him, led to Torricelli traveling to Florencewhere he met Galileo, and acted as his amanuensis during the three remaining months of his life.

The purpose of his experiment is to prove that the source of vacuum comes from atmospheric pressure.

Evangelista Torricelli

The discovery of the principle of the barometer has perpetuated his fame “Torricellian tube”, “Torricellian vacuum”. This was seen as an “incredible” dd by many at the time, including Torricelli himself, and prompted a fierce controversy about the nature of infinity, also involving the philosopher Hobbes. Seeing his talents, his parents sent him to be educated in Faenza, under the care of his uncle, Giacomo Jacoba Camaldolese monkwho first ensured that his nephew was given a sound basic education.

Evangelista Torricelli was born on 15 October in Rome ; he invented the barometer in Florence, Italy. Retrieved 2 Barometroo Golinski, in The sciences in Enlightened Europeediteby by W.

Any air bubbles in the tube must be removed by inverting several times. He also stated that the changes of liquid level yorricelli day to day are caused by the variation of atmospheric pressure. Torricelli is also famous for the discovery of the Torricelli’s trumpet also – perhaps more often – known as Gabriel’s Horn whose surface area is infinitebut whose volume is finite.
