What is Otto von Guericke most famous for?
A politician, physicist, engineer, and natural philosopher, von Guericke invented the world’s first air pump in 1650. By performing and interpreting some pioneering vacuum experiments, he made important contributions to the basic principles of the physics of fluids and gases.
How did Otto von Guericke change the world?
After surviving the worst massacre of the Thirty Years’ War, Otto von Guericke made several historic scientific discoveries. Self-funded, he invented the vacuum pump, pioneered the concept of the absolute vacuum of space, measured the weight of air and used air pressure to make weather forecasts.
How did Otto von Guericke test Aristotle’s belief?
Even Aristotle argued against its existence. When he began his research, von Guericke studied the role of air in respiration and combustion and attempted to disprove the idea that a vacuum could not exist in nature.
Who invented the hemispheres?
Otto von Guericke
The Magdeburg hemispheres were invented by German scientist and mayor of Magdeburg, Otto von Guericke, to demonstrate the air pump that he had invented, and the concept of atmospheric pressure.
What was Otto von Guericke experiment?
A German scientist, Otto Von Guericke placed two hollow metal hemispheres together. Then almost all the air from the combined hemispheres was removed using vacuum pump. The teams of horses were attached at both the ends of hemispheres.

Otto von Guericke/Inventions
In 1650 von Guericke invented the vacuum pump. His model consisting of a piston and an air gun cylinder with two-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.
How did Otto von Guericke demonstrate air pressure?
In 1650 Guericke invented the air pump, which he used to create a partial vacuum. After he had removed the air from the sphere, horses were unable to pull the bowls apart, even though they were held together only by the air around them. The tremendous force that air pressure exerts was thus first demonstrated.
Are there 4 hemispheres?
There are generally considered to be four hemispheres: Northern, Southern, Eastern, and Western. The Equator, or line of 0 degrees latitude, divides the Earth into the Northern and Southern hemispheres.
What did the Magdeburg experiment demonstrate about air pressure?
The Magdeburg Hemispheres is a classic physics experiment that demonstrates the incredible pressure the atmosphere around us exerts on our bodies and everything else. The apparatus of the experiment consist of two brass hemispheres that fit together to form an air-tight seal.
How does the Magdeburg experiment work?
Magdeburg hemispheres are two half-spheres of equal size. Placing them together traps air between them. This air is merely trapped, and not compressed, so the pressure inside is the same as the pressure of the atmosphere outside the spheres. That is to say, the air is pushing equally strongly inside as it is outside.
What do you call half a hemisphere?
A hemisphere is a half-sphere, for example, half the Earth: northern, southern, eastern, western hemisphere. In a forum post related to a ESA satellite station in Argentina, I came across the phrase “having such an strategic and experienced partner on the South West hemisphere”.
