The Barometer By: Paul Karkenny
Timeline of the Barometer 1643- Mercury barometer invented 1843- Aneroid barometer is invented 1648- Pascal performs his famous experiment
Evangelista Torricelli • Born in 1608 • German Physicist • Invented first barometer • Died in 1647
Creation of the barometer • Invented by Evangelista Torricelli in 1643 • Disproving tradition • Why Mercury? • Torricelli’s barometer
Creation of the barometer • In 1648, Pascal proves relationship between atmospheric pressure and altitude. • In 1843, the French scientist Lucien Vidie invented the aneroid barometer.
How does it work? • Measures atmospheric air pressure • Mercury Barometer
How does it work? • Aneroid Barometer
Importance in modern world • Weather forecasting • Storm Chasers • Pressure Maps • Flying aircraft
