Since ancient times, man, as a farmer and navigator, has observed and attempted to predict climate trends. The scientific study of the changes that occur in the atmosphere began in the mid-17th century, in connection with experiments aimed at demonstrating the existence of the void, which the ancient philosophers denied because "nature abhors a void!".
If you fill a long tube with water and place it upside down in a bucket of water, the column of liquid will descend until its weight is counterbalanced by the pressure of the air on the surface of the water contained in the bucket: at a certain point there will be a vacuum in the upper, closed end of the tube.
Evangelista Torricelli (1608-1647), mathematician and physicist, disciple of Galileo, was the first, in 1643, to build an instrument capable of detecting changes in air pressure. He described his experiment as the result of the discovery that changes in atmospheric pressure are linked to changes in the weather.
