Pascal's expedition to prove air pressure theories
Numéro d’image : 11830509
| Pascal's expedition. Engraving of the brother-in- law and two friends of the French physicist Blaise Pascal. They are carrying out an experiment in air pressure on the physicist's behalf. Pascal,who was also a mathematician and a philosopher,wanted to prove Torricel's prediction that air pressure would decrease with altitude. To do this a mercury barometer was carried to the summit of the Puy de Dome mountain,France (1200 metres high). The barometer recorded a drop in air pressure as the party made their ascent,thus proving Torricel's prediction | |
