What did Evangelista Torricelli accomplish?
Evangelista Torricelli, (born Oct. 15, 1608, Faenza, Romagna—died Oct. 25, 1647, Florence), Italian physicist and mathematician who invented the barometer and whose work in geometry aided in the eventual development of integral calculus.
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.
How did Evangelista Torricelli contribution to atomic theory?
Torricelli predicted that the height of the mercury column would change from day to day as the pressure of the atmosphere changed. Today, his apparatus is known as a barometer, from the Greek baros, meaning “weight,” because it literally measures the weight of the atmosphere.
How do you pronounce e Torricelli?
Phonetic spelling of Evangelista Torricelli
- E-van-ge-lista Tor-ri-celli.
- evangelista torricelli. Grace Spencer.
- Evan-gelista Tor-ri-celli. Joaquin Hirthe.
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.
How did Evangelista Torricelli discover pressure?
Lived 1608 – 1647. Evangelista Torricelli was one of these people. He invented the mercury barometer and deduced from experiments that his device revealed the height of our planet’s atmosphere. In 1644, he concluded that we live at the bottom of a sea of air.
What is the meaning of Torricelli?
Definition of Torricelli’s law : a law in hydrodynamics: the speed of efflux of a liquid from an orifice is equal to that of a body falling freely through a distance equal to the total head of the liquid at the orifice.
Who invented barometer?
Evangelista Torricelli
Barometer/Inventors
The mercury barometer is the oldest type of barometer, invented by the Italian physicist Evangelista Torricelli in 1643. Torricelli conducted his first barometric experiments using a tube of water.
Who invented mm Hg?
Evangelista Torricelli. In the early 1600s, Galileo argued that suction pumps were able to draw water from a well because of the “force of vacuum” inside the pump. After Galileo’s death, the Italian mathematician and physicist Evangelista Torricelli (1608-1647) proposed another explanation.

Why did Evangelista Torricelli invent barometer?
Evangelista Torricelli became the first scientist to create a sustained vacuum and to discover the principle of a barometer. Torricelli realized that the variation of the height of the mercury from day to day was caused by changes in the atmospheric pressure. Torricelli built the first mercury barometer around 1644.
What is the contribution of Evangelista Torricelli?
Evangelista Torricelli. Evangelista Torricelli was a gifted Italian physicist and mathematician. He was the first person to create a sustained vacuum and he invented the barometer. An excellent mathematician, his work in geometry helped towards the discovery of integral calculus in the mid-seventeenth century.
What did Giuseppe Torricelli contribute to science?
He and his followers contributed greatly to the study of digestion and body fluids. Torricelli (1608-1647) invented the barometer, to measure air pressure, in 1643. This was a large step in the understanding of the properties of air, and the basic structure of the barometer remains the same today.
What did Torricelli say about the Solar System?
Torricelli informs Galileo (and us) that he has studied the works of the great Ancient Greek mathematicians, such as Archimedes’, and has studied the works of Ptolemy, Tycho Brahe, and Kepler. He says that he agrees with the Copernican view of the solar system. This was the only time Torricelli ever openly supported the Copernican view.
What did Torricelli contribute to the development of the barometer?
Contributions and Achievements: Torricelli carried out experiments using heavier and heavier liquids, resulting in an experiment that created a sustainable vacuum, using mercury, with a glass tube roughly one meter long. This experiment led to the development of the barometer.
