Wellcome V0005861 Torricelli invented the mercury barometer, recorded in the books of Camille Flammarion (1923) Torricelli's experiment was invented in Pisa in 1643 by the Italian scientist Evangelista Torricelli (1608-1647). The purpose of his experiment is to prove that the source of "horror of the vacuum" by nature comes from atmospheric ...
Evangelista Torricelli portrayed on the frontpage of Lezioni d'Evangelista Torricelli Torricelli's experiment Torricelli lunar crater map. Torricelli died of fever, most likely typhoid, [12] [13] in Florence on 25 October 1647, [14] 10 days after his 39th birthday, and was buried at the Basilica of San Lorenzo. He left all his belongings to his ...

Evangelista Torricelli. Evangelista Torricelli, a friend and student of Galileo, interpreted the results of the experiments in a novel way. He proposed that the weight of the atmosphere, not an attracting force of the vacuum, held the water in the tube. In a letter to Michelangelo Ricci in 1644 concerning the experiments, he wrote:
This experiment essentially paved the way towards the invention of the barometer, as well as drawing the attention of Robert Boyle, then a "skeptical" scientist working in England. Boyle was inspired by Torricelli's experiment to investigate how the elasticity of air responds to varying pressure, and he did this through a series of experiments ...
Torricelli attributes this defect to the air resistance and to the fact that the descending drops collide with ascending drops. Torricelli's argumentation is, as a matter of fact, wrong because the pressure in free jet is the surrounding atmospheric pressure, while the pressure in a communicating vessel is the hydrostatic pressure.
Torricelli's equation, an equation created by Evangelista Torricelli; Torricelli's trumpet or Gabriel's Horn, a geometric figure; Torricelli point or Fermat point, a point such that the total distance from the three vertices of the triangle to the point is the minimum possible; Torricelli's experiment, an experiment named after Torricelli
The theorem of Torricelli was employed by many succeeding writers, but particularly by Edme Mariotte (1620–1684), whose Traité du mouvement des eaux, published after his death in the year 1686, is founded on a great variety of well-conducted experiments on the motion of fluids, performed at Versailles and Chantilly. In the discussion of some ...
