Galileo Galilei
February 15, 1564, Pisa, Italy - January 8, 1642, (aged 77), Arcetri, Italy Galileo Galilei constructed a thermometer which used the expansion and contraction of gas in a light bulb. Had troubles with the church. They told him to give up the heliocentric model. -
Otto Von Guericke
November 20, 1602, Magdeburg, Germany - May 11, 1686,(aged 83) Hamburg, Germany Otto Von Guericke was most known for his studies with air pressure and the concept of atmospheric pressure when he was 54 years old. The first artificial vaccum invented by Evangelista Torricelli inspired von Guericke to design the world's first vaccum. Guericke's pump helped Robert Boyle formulate Boyle's Law, which states that the volume of an ideal gas is proportional to its pressure. -
Evangelista Torricelli
October 15, 1608, Faenza, Italy - October 25, 1647 (aged 39), Florence, Italy. Evangelista Torricelli conducted expiriments on gases which led to his invention, the mercury barometer. He was Galileo's assistant. -
Blaise Pascal
June 19, 1623, Clemont-Ferrand, France - August 19, 1662 (aged 39), Paris, France. Blaise Pascal stated that a fluid (liquid or gas) at rest in a closed conatiner, pressure change in one part is transmitted without loss to every portion of the fluid and to the walls of the container around his early twenties. Has a unit of atmospheric pressure named after him. -
Christiaan Huygens
April 14, 1629, The Hague, Netherlands - July 8,1695, (aged 66) Netherlands. Christiaan Huygens invented the manometer to measure the pressure of liquids and gases when he was 32 years old. Huygens also proposed that light is not made of particles, but waves. -
John Dalton
September 6, 1766, Cumberland, England - July 27, 1844 (aged 77), Manchester, England John Dalton stated that the total pressure applied by the mixture of non-reactive gases is the same as the partial pressures of individual gases when he was 35 years old. John Dalton was colour blind and he wrote a book about it. -
Amedeo Avogadro
August 9, 1776, Turin, Italy - July 9, 1856 (aged 79), Turin, Italy Amedeo Avogadro stated that equal volumes of all gases at the same temperature and pressure contains the same number of molecules when he was 35 years old. One of his most important contributions is that gases are made of molecules and molecules are made of atoms. Avogadro's law is 6.023 x 10 to the 23rd power. His theory almost got neglected, but years after his death, people began to realize it.
