Since the height of a barometer’s mercury column is a measure of the weight of the air above us, it’s not surprising that if you climb a mountain the mercury column’s height will fall. Život. In 1644, he concluded that we live at the bottom of a sea of air. [1] je bio italijanski fizičar, matematičar i dobar prijatelj Galileo Galileja.[2].
