Air pressure and the vacuum In 1650 he invented a vacuum pump consisting of a piston and cylinder with one-way flaps designed to pull air out of whatever vessel it was connected to, and used it to investigate the properties of the vacuum in many experiments. Guericke demonstrated the force of air pressure with dramatic experiments, e.g. in 1663 at the court of Friedrich Wilhelm I of Brandenburg. Guericke had joined two copper hemispheres of 51 cm diameter (Magdeburg hemispheres) and pumped the air out of the enclosure. Then he harnessed a team of eight horses to each hemisphere and showed that they were not able to separate the hemispheres. When air was again let into the enclosure, they were easily separated. He repeated this demonstration in Berlin, in 1663, using 24 horses.

With his experiments Guericke disproved the hypothesis of "horror vacui", that nature abhors a vacuum, that for centuries was a problem for philosophers and scientists. Guericke proved that substances were not pulled by a vacuum, but were pushed by the pressure of the surrounding fluids. Thus he made a first rate scientific discovery. In art history, especially in the criticism of painting, horror vacui describes the filling of every empty space in a work of art with some sort of design or image. ...
Other investigations Guericke applied the barometer to weather prediction and thus prepared the way for meteorology. His later works focused on electricity, but little is preserved of his results. He invented the first electrostatic generator, the "Elektrisiermaschine". A barometer is an instrument used to measure atmospheric pressure. ...
