Galileo Galilei
Died - January 8, 1642
Age - 77 Contibution to pressure - Built a device to show hotness called the thermoscope in 1593
Age at Contibution - 29 most of his works were in astronomy, not pressure -
Period: Feb 15, 1564 to
The D.O.B's of the 7 Scientists
Dates of scientists' births, and their contribution to pressure. -
Otto Von Guericke
Died - May 11, 1686
Age - 83 Contibution to pressure - Created a vaccum pump and chamber around 1650
Age at contribution - around 48 He invented the first electro-static generator. -
Evangelista Torricelli
October 25, 1647
Age - 39 Contibution to pressure - Created first Mercury Barometer in 1643
Age at contribution - 35 He gave the first scientific description for the cause of wind. -
Blaise Paskal
Died - August 19, 1662
Age - 39 Contribution to pressure - Helped prove vaccums can exist when it was thought they were impossible to create
Age at contribution - 24 The pressure measurement "Pascal" was named after Paskal for his contibutions to science -
Christiaan Huygens
Died - July 8, 1695
Age - 66 Contribution to pressure - Built the U-tube pressure measurement device 1661
Age at contibution - 32 He wrote the first book about probablity theory -
John Dalton
Died - July 27, 1844
Age - 77 Contibution to pressure - Dalton created Dalton's law, which was also known as Dalton's Law of Partial Pressures. This law stated what the total pressure exerted by a gaseous mixture was equal to the sum of the partial pressures of each individual component in a gas mixture. Although his law isn't followed by actual gases, those deviations are are considered to be large at high pressures. Dalton also observed the empirical law.
Age at contribution - 35 -
Amedeo Carlo Avogadro
Died - July 9, 1856
Age - 79 Contibution to pressure - Created avogadro's law, which states that the relationship between the masses of the same volume of different gases at the same temperature and pressure corresponds to the relationship between their respective molecular weights.
Age at contibution - approx 38 When he was 20, Avogadro was studying law not physics
