Home Encyclopedia Summa Fathers ... T > Evangelista Torricelli A B C D ... Z Evangelista Torricelli Italian mathematician and physicist, born at Faenza, 15 October, 1608; died at Florence, 25 October, 1647. Modigliana, in Tuscan Romagna, and Piancaldoli, in the Diocese of Imola, are named as the birthplace by different biographers. Torricelli was educated at the Jesuit college of Faenza, where he showed such great aptitude for the sciences that his uncle, a religious of the order of the Camaldolesi, sent him to Rome in 1626 for the purpose of study. There he fell in with Castelli, the favorite pupil of Galileo , who instructed him in the work of the master on the laws of motion. Torricelli showed his thorough understanding by writing a thesis on the path of projectiles. Castelli sent this essay in manuscript to Galileo with strong recommendations of his young friend. Galileo invited Torricelli to his house but for personal reasons he was unable to accept until three months before the death of the blind scientist (1641). The grand duke prevailed upon him to remain at Florence and to succeed Galileo at the Academy. He solved some of the great mathematical problems of the day, such as the finding of the area and the centre of gravity of the cycloid. This problem gave rise to disagreeable discussion on the part of Roberval as to priority and originality. Torricelli's honesty, manliness, and modesty are distinctly shown in his reply.

Evangelista Torricelli - 1608 - 1647 - English Italiano Were Evangelista Torricelli and Vincenzo Viviani, two followers of Galileo, to find out the lift pump's enigma. To repeat their famous experiment (please see the animation), you must fill an empty glass tube, sealed at one end, with mercury. Then you must partially fill a glass cup (with mercury). Afterwards, you must cover the open end with a finger, invert it, and plunge it into the mercury in the dish. Now, take off your finger from the end of the tube. The mercury will then run out of the tube into the dish until the weight of the column of mercury in the tube exactly balances the outside air pressure. The mercury in the tube will rise when the air pressure increases and will fall when it decreases. The exact measure of the air pressure at any moment is the height of the mercury in the tube above the level of the mercury in the dish. Under standard conditions at sea level, the height will be 29.92 inches or 76 centimetres. Vincenzo Viviani was the first man to assume that the mercury descent was stopped by the air weight (pressure). When the experiment is over, in the glass tube over the mercury there is nothingh !!!

It was a fairly poor family with Gaspare being a textile worker. Evangelista was the eldest of his parents three children, having two younger brothers at least one of whom went on to work with cloth. It is greatly to his parents' credit that they saw that their eldest son had remarkable talents and, lacking the resources to provide an education for him themselves, they sent him to his uncle who was a Camaldolese monk. Brother Jacopo saw that Evangelista was given a sound education until he was old enough to enter a Jesuit school. Torricelli entered a Jesuit College in 1624 and studied mathematics and philosophy there until 1626. It is not entirely clear at which College he studied, with most historians believing that he attended the Jesuit College in Faenza, while some believe that he entered the Collegio Romano in Rome. What is undoubtedly the case is that after study at the Jesuit College he was then in Rome. Certain facts are clear, namely that Torricelli's father died in or before 1626 and that his mother moved to Rome for she was certainly living there in 1641 at the time of her death. Torricelli's two brothers also moved to Rome and again we know for certain that they were living there in 1647. The most likely events seem to be that after Gaspare Torricelli died, Caterina and her two younger sons moved to Rome to be with Evangelista who was either already living there or about to move to that city.

The first barometer English Italiano Selected by the sciLINKS program, a service of National Science Teachers Association. In this experiment, Torricelli used mercury which is more than 13 times as heavy as water. A water barometer would require a tube more than 30 feet long and the water, of course, would freeze at winter temperatures. Furthermore, water and most other common liquids release vapor which would decrease the vacuum at the top of the tube, whereas cold mercury releases very little vapor. A glass tube, sealed at one end, is filled with mercury. Then a glass dish is partially filled with mercury. Cover the open end of the tube with a finger, invert it, and plunge it into the mercury in the dish. Mercury will then run out of the tube into the dish until the weight of the column of mercury in the tube exactly balances the outside air pressure. Under standard conditions at sea level, the height will be 29.92 inch or 76 centimetres. This experiment is important in science and technology history. The first steam engines (Papin, Newcomen) were "atmospheric engines".

Evangelista Torricelli - 1608 - 1647 - Galileo, che si era dedicato al problema della pompa aspirante, morì prima di risolvere il mistero. L'onore toccò a due suoi allievi, Evangelista Torricelli e Vincenzo Viviani. Nel 1643 essi fecero il loro celebre esperimento (vedere l'animazione). Esso dimostrò inequivocabilmente che: IL VUOTO PUO' ESISTERE !! e che L'ARIA HA UN SUO PESO !! Il mistero della pompa aspirante è risolto: l'altezza di aspirazione dipende dalla pressione atmosferica e, per questo motivo, non può superare i 9 metri. L'altezza teorica di aspirazione sarebbe (al mare) di 10,33 metri. Questa altezza sarebbe possibile solo realizzando il vuoto assoluto all'interno del cilindro della pompa per sfruttare tutta la pressione atmosferica. Raggiungere il vuoto assoluto è però impossibile e altezze di aspirazione di 9 metri sono già eccezionali. Questo esperimento fu il primo passo lungo la strada che doveva condurre alla realizzazione della macchina a vapore. Le prime macchine infatti sfruttavano il vapore solo per creare il vuoto dentro un cilindro e sotto un pistone.

Evangelista Torricelli (1608-1647) Letter to Michelangelo Ricci concerning the Barometer Collected Works Vol. III (1919) [from William Francis Magie, A Source Book in Physics (New York: McGraw-Hill, 1935) (translator?)] To Michelangelo Ricci in Rome. Florence, June 11, 1644 Most Illustrious Sir and Most Learned Patron: We have made many vessels of glass like those shown as A and B and with tubes two cubits long. These were filled with quicksilver , the open end was closed with the finger, and they were then inverted in a vessel where there was quicksilver C ; then we saw that an empty space was formed and that nothing happened in the vessel where this space was formed; the tube between A and D remained always full to the height of a cubit and a quarter and an inch over. To show that the vessel was entirely empty, we filled the bowl with pure water up to D and then, raising the tube little by little, we saw that, when the opening of the tube reached the water, the quicksilver fell out of the tube and the water rushed with great violence up to the mark E . It is often said in explanation of the fact that the vessel AE stands empty and the quicksilver, although heavy, is sustained in the tube

Evangelista Torricelli 1608 až 1647 existence tlaku vzduchu Život Evangelisty Torricelliho se celý odehrál v první polovinì 16. století. Našli bychom øadu dalších významných osobností, které se postaraly o velkolepý rozvoj novovìké vìdy právì v tomto období. Galilei, Descartes, Huygens, Pascal, Roberval i Fermat, ti všichni zásadní mìrou pøispìli k obohacení lidského poznání a k uplatnìní dedukcí i zobecnìní ve vìdì. Evangelista Torricelli se narodil 15.10. 1608 ve Feanze, zhruba rok pøed tím, než se Galileo Galilei zaèal dívat dalekohledem na oblohu. Tuto souvislost nepøipomínáme náhodou, vždy Torricelliho mùžeme považovat za Galileiho žáka, který se zabýval mj. právì i broušením èoèek do dalekohledù. Jestliže Galileo Galilei propracoval vrhy a pády tìles v zemském gravitaèním poli, Torricelli zkoumal úèinky zemské tíže na kapaliny. Pro rychlost výtoku otvorem ve stìnì nádoby v hloubce h pod hladinou nalezl vztah , tedy stejný, jako platí pro rychlost volného pádu po uražení dráhy h. První ucelené základy hydrodynamiky nalezneme právì v Torricelliho díle Trattato del moto z roku 1641. Jako druhou etapu Torricelliho vìdeckého zájmu mùžeme oznaèit pokusy s atmosférickým tlakem vzduchu. Pokusy vlastnì zaèal Vincenzio Viviani a na jejich základì Torricelli zavrhl aristotelovský pojem horror vacui a zavedl oznaèení atmosférický tlak vzduchu. Proslulý pokus s trubicí naplnìnou rtutí a pak pøevrácenou vyvolal øadu otázek a zdaleka ne všichni byli o vzduchoprázdnu nad rtuovým sloupcem pøesvìdèeni. Skalní aristoteliky, ale také pøíznivce Descarta, pokus nepøesvìdèil a ti stále tvrdili, že v uzavøeném prostoru nad rtutí cosi je, "nebo sklo má velmi jemné póry, jimiž mohou pronikat paprsky svìtla, magnetu a jiné velmi drobounké èásteèky hmoty". Tento názor sdílel napø. i G. W. Leibniz. V této dobì definitivnì padl názor na vzduch jako bezhmotnou a beztížnou substanci ve smyslu antického uèení o ètyøech živlech.

Nadien was hij in Rome Hij studeerde er onder Benedetto Castelli die doceerde aan de Universiteit van Sapienza, zo genoemd naar het gebouw waar het gehuisvest was. Hij leerde er wiskunde mechanica hydraulica en sterrenkunde , werd Castelli's secretaris en nam later de lessen voor hem waar. Hij interesseerde zich sterk voor het nieuwe Copernicaanse wereldbeeld en schreef er met Galileo Galilei over. Toen deze echter in 1633 onder druk kwam te staan van de Inquisitie achtte Torricelli het wijzer zich voortaan met de veiliger wiskunde te bemoeien. Hij werkte nu voor Ciampoli en woonde waarschijnlijk in een aantal andere steden, o.a. in Umbria. In 1641 had hij het meeste werk dat hij in 1644 in zijn Opera geometrica zou publiceren al gereed en daarna begon hij aan zijn De motu gravium Door zijn werk kwam hij opnieuw in contact met Galilei en werd voor enige maanden zijn assistent. Toen Galilei stierf werd hij benoemd als diens opvolger als hofwiskundige van de Groothertog Ferdinand van Toscane.
