Torricelli's Biography

Torricelli (1608-1647) was an Italian physicist and mathematician. He discovered the principle of the barometer. His studies on calculus gave rise to the Integral Calculus. He dedicated himself to the study and planning of telescopes, microscopes and precision instruments.

Torricelli (1608-1647) was born in Faenza, a region in northern Italy, on October 15, 1608. He was a brilliant pupil of the Jesuit College of Faenza. At the age of 16 he was sent to Rome to study with Benedetti Castelli, who was a disciple of Galileo and a professor of mathematics at the Collegio di Sapienza. Torricelle's first essay, "On the Projectiles," was sent to Galileo who was impressed by the student's analytical and mathematical ability.
In 1641 the Grand Duke of Tuscany invited Torricelli to join Galileo's then-78-year-old, almost blind team of collaborators. They did not work together for long, three months later, on January 8, 1642, Galileo died. Torricelli was immediately appointed mathematician of the Grand Duke.

Evangelist Torricelli spent his last days working and teaching classes that attracted scientists from all over Italy and other regions of Europe. He died in Florence on October 25, 1647.

Torricelli's experiment

The Italian physicist and mathematician Evangelista Torricelli (1608-1647), a friend of Galileo Galilei, carried out various experiments in order to measure the atmospheric pressure. Torricelli used a 1m long graduated tube closed at one end. He filled the tube with mercury and plunged the open end into a vessel containing mercury. Reflecting on the fact that, after a certain time, the vessel level no longer varied, Torricelli was conclusive in determining that atmospheric pressure did this action. And since the mark presented was 76 cm, it defined that the atmospheric pressure would have the value of 760 mm of Hg (chemical symbol of the mercury). Torricelli performed this experiment more often, varying the site. He verified that the altitude influenced the height of the column of mercury, which led him to the conclusion that the atmospheric pressure decreases with the altitude. And why did you use mercury? Torricelli used mercury because it is a liquid metal, at room temperat...
