Raffaello Magiotti
Raffaello Magiotti ( born September 5, 1597 Montevarchi ( Arezzo, Tuscany ), † 1656 in Rome ) was an Italian physicist, mathematician, and astronomer who is most famous for, he has described the incompressibility of water.
He studied in Florence and moved after he had entered a religious order, with Cardinal Sacchetti in Rome. In 1636 he began to work in the Vatican Library. As a student of Benedetto Castelli in 1638 he was a candidate for the chair of mathematics in Pisa. As in the papal city, he was also in the scientific community at home to Magiotti actively participated in the scientific debates in Rome, about which he reported in detail on Galileo, with whom he was in contact often.
Magiotti played an important role in the research that preceded the experiments Torricelli's barometer and gave them to a large extent the way. He supported the lifter experiments by Gasparo Berti in 1640 by he wrote detailed descriptions in various letters. In a letter to Mersenne of 1648 he described this period of the experiments, and revealed that he had Torricelli informed about the trials of Berti. He also suggested the use of sea water, which is denser than fresh water, and related mercury in barometric experiments.
Magiotti only published one book that had ( The resistance of the water against compression) the title " Renitenza certissima dell'acqua alla compressione " and in 1648 came out. It was the first report on the incompressibility of water, the Magiotti falsely regarded as absolute, as well as on the expansion and contraction of liquids and gases (water and air), the temperature changes are subject. In addition to the description of various thermometers, the book also contains an illustration of the Cartesian diver ( diver bottles, Cartesian devil), whose discovery is therefore attributed to the Tuscan scientist and not Descartes, after which it is named.
1656 Magiotti died of the plague.
Francesco Redi, whom he met in 1650, said of him: " Magiotti is a great sage, and I try to be together whenever I can because I 'm learning something nice from him every time with him."
