Why did Otto von Guericke go to Magdeburg?
It is named after the physicist and mayor of Magdeburg Otto von Guericke, famous for his experiments with the Magdeburg hemispheres. The former Technical University Magdeburg (Technische Hochschule Magdeburg), a teacher training college and a medical school were absorbed into the university when it was created.
What did Guericke do?
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.
What did von Guericke improve?
In 1663 he invented the first electric generator, which produced static electricity by applying friction against a revolving ball of sulfur. In 1672 he discovered that the electricity thus produced could cause the surface of the sulfur ball to glow; hence, he became the first man to view electroluminescence.
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.
What is the use of Magdeburg hemisphere?
The Magdeburg hemispheres are a pair of large copper hemispheres, with mating rims. They were used to demonstrate the power of atmospheric pressure.
How did Otto von Guericke invent the air pump?
To prove that a vacuum and atmospheric pressure existed, von Guericke performed one of his most well-known experiments: the Magdeburg Hemispheres. Von Guericke placed two 20-inch copper hemispheres together and used his pump to remove the air inside, creating a sealed vacuum.
What are the Magdeburg hemispheres and how do they 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 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.
Is Magdeburg a good university?
Otto von Guericke University Magdeburg is ranked 601 in Academic Ranking of World Universities by Shanghai Jiao Tong University and has an overall score of 4.0 stars, according to student reviews on Studyportals, the best place to find out how students rate their study and living experience at universities from all …
Why did Otto von Guericke invent the vacuum pump?
The Vacuum Pump Guericke saw his hometown consumed by fire in 1631. In the 1640s, he began trialing water pumps for firefighting. In about 1647, Guericke began modifying water pumps. He discovered that he could use a pump to remove air from a sealed metal or glass jar.
