Ottovon Guericke (1602¨C1686) was a German physicist and engineer, born in Maddeburg on 20 November 1602, who studied law, digital, urban engineering, and other universities in Leipzig, Himmstat, Jena, Leiden. The 1930s war turned his hometown of Maddeburg into ruins, and in 1646 he became the mayor of the city for 35 years.

He used his time to engage in research into many aspects of physical experimentation, the main achievements of which came from his book The New Experiment on Emptiness (1672).

In 1605, Galic invented and built the first air pump, which used various containers to create vacuum, and proved that no sound could be spread in the vacuum, it could not sustain burning, it could not sustain the life of animals.

The 1654 "Maddenburg Peninsula Experiment" demonstrated the enormous pressure of the atmosphere, making the concept of vacuum and atmospheric pressure accepted by the world.

Galic also achieved important achievements in electrics. He himself built a friction engine, which was made of sulfur balls that can be rotated on the curved axis, and each rotation produced some static electricity and coalesced in the sulfur ball, so that continuous discharge experiments could be demonstrated. Using this instrument, he discovered the phenomenon of static sensing, that a small object will be powered as soon as it is close to the electrical object. In addition, he also discovered the phenomenon of the same-sex charge.
