Torricelli, Evangelista Italian physicist who established the existence of atmospheric pressure and devised the mercury barometer 1644. In 1643 Torricelli filled a long glass tube, closed at one end, with mercury and inverted it in a dish of mercury. Atmospheric pressure supported a column of mercury about 76 cm/30 in long; the space above the mercury was a vacuum. Noticing that the height of the mercury column varied slightly from day to day, he came to the conclusion that this was a reflection of variations in atmospheric pressure. Torricelli was born in Faenza and studied at the Sapienza College, Rome. When physicist Galileo read Torricelli's De motu gravium naturaliter descendentium et proiectorum 1641, which dealt with movement, he invited him to Florence, where he served as Galileo's secretary for the three months till his death. From 1642 Torricelli was professor of mathematics at Florence.

History of Science index Evangelista Torricelli Torricelli detail of a portrait by an unknown artist (b. Oct. 15, 1608, Faenza, Romagnad. 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. Inspired by Galileo's writings, he wrote a treatise on mechanics, De Motu ("Concerning Movement"), which impressed Galileo. In 1641 Torricelli was invited to Florence, where he served the elderly astronomer as secretary and assistant during the last three months of Galileo's life. Torricelli was then appointed to succeed him as professor of mathematics at the Florentine Academy. Two years later, pursuing a suggestion by Galileo, he filled a glass tube 4 feet (1.2 m) long with mercury and inverted the tube into a dish. He observed that some of the mercury did not flow out and that the space above the mercury in the tube was a vacuum. Torricelli became the first man to create a sustained vacuum. After much observation, he concluded that the variation of the height of the mercury from day to day was caused by changes in atmospheric pressure. He never published his findings, however, because he was too deeply involved in the study of pure mathematicsincluding calculations of the cycloid, a geometric curve described by a point on the rim of a turning wheel. In his Opera Geometrica (1644; "Geometric Works")

Evangelista Torricelli Em 1608, o aparecimento da luneta nas mãos pesquisadoras de Galileu abriu as portas da ciência astronômica. Tornou-se possível estudar as montanhas da Lua, os satélites de Júpiter, as fases de Vênus e a variação do diâmetro aparente dos planetas. Caíam por terra velhas doutrinas: passou a ser exigido de um cientista que deixasse de procurar a verdade nas Sagradas Escrituras para olhar à sua volta e arrancá-la do que observava. Muitos ramos da ciência beneficiaram-se com o método experimental de Galileu. Colocou-se na ordem do dia a realização de experiências e a construção de aparelhos para a pesquisa. Começava a nascer a idéia da ligação íntima existente entre teoria e prática. Os estudiosos tinham, atrás de si, séculos de automistificação, em que velhas e veneráveis teorias permaneciam "oficiais", mesmo quando afirmavam o contrário do que ocorria realmente. O advento do método científico, com seu rigorismo e sua pouca propensão a aceitar argumentos não fundamentados na experiência, foi uma injeção de vitalidade no edifício científico medieval. (Casa onde nasceu) No ano de 1608, a 15 de outubro, nascia em Faenza um futuro cientista, destinado a desempenhar importante papel no desenvolvimento das idéias de Galileu. Seu nome era Evangelista Torricelli, o responsável pela comprovação do pêso do ar, também conhecido como precursor de Newton e Leibniz no desenvolvimento do cálculo infinitesimal.

Inicio Buscador Las figuras clave de la historia Reportajes Los protagonistas de la actualidad Evangelista Torricelli (Faenza, actual Italia, 1608-Florencia, 1647) Físico y matemático italiano. Se atribuye a Evangelista Torricelli la invención del barómetro. Asimismo, sus aportaciones a la geometría fueron determinantes en el desarrollo del cálculo integral. Su tratado sobre mecánica De mutu (Acerca del movimiento), logró impresionar a Galileo, en quien el propio Torricelli se había inspirado a la hora de redactar la obra. En 1641 recibió una invitación para actuar como asistente de un ya anciano Galileo en Florencia, durante los que fueron los tres últimos meses de vida del célebre astrónomo de Pisa. Torricelli A la muerte de Galileo, Torricelli fue nombrado profesor de matemáticas de la Academia Florentina. Dos años más tarde, atendiendo una sugerencia formulada por Galileo, llenó con mercurio un tubo de vidrio de 1,2 m de longitud, y lo invirtió sobre un plato; comprobó entonces que el mercurio no se escapaba, y observó que en el espacio existente por encima del metal se creaba el vacío. Tras muchas observaciones, concluyó que las variaciones en la altura de la columna de mercurio se deben a cambios en la presión atmosférica. Nunca llegó a publicar estas conclusiones, dado que se entregó de lleno al estudio de la matemática pura, incluyendo en su labor cálculos sobre la cicloide y otras figuras geométricas complejas.

FICHA Nacionalidad: Italia Nacido en 1608, sucedió a Galileo como profesor de filosofía y matemáticas en Florencia. Sus investigaciones en física le llevaron a descubrir la presión atmosférica y a inventar el barómetro. Formuló el "principio de Torricelli", relativo a la salida de los cuerpos líquidos por un orificio en pared delgada. En matemática , mejoró el método de los indivisibles de Cavalieri.

Evangelista Torricelli Le baromètre par Karen-Lynn Anderson et Vanessa Gagnon Biographie Après réflexion sur cette expérience, il comprit qu'il venait de faire le vide. Il soumit l'hypothèse suivante à un collègue : "L'air (la pression atmosphérique) pèse sur le mercure de la cuve, ce qui empêche le mercure de descendre complètement et le tube de se vider. Il mesura ainsi la pression atmosphérique." Il confirma par la suite son hypothèse et conclut que la pression atmosphérique détermine la hauteur à laquelle s'élèvera un fluide dans un tube inversé dans un bac contenant le même liquide.
