Who proposed the Magdeburg hemispheric experiment

It was an experiment carried out by the mayor of Magdeburg, Otto von Gülic, in Regensburg, Germany.

Sometimes, one can use very simple tools to demonstrate extraordinary physics. Magdeburg Hemispheric Experiment.

, there is a pair of iron hemispheres, each with a handle attached, and on one side there is a valve that allows air to be pumped out, which is atmospheric pressure.

A small scale model of the power display. They are known as the Magdeburg Hemisphere, and until now it remains a great presentation tool.

Curiously, the hemisphere was named not after one person, but after one place, which was Magdeburg, Germany. The spheres were designed in 1654 by the German scientist (and mayor of Magdeburg) Otto von Guericke and demonstrated his newly invented vacuum pump.

and atmospheric pressure concepts. Its principle is simple, when two hemispheres are pressed together, air is pumped out from the inside, creating a partial vacuum that seals the two hemispheres together with tremendous force.

Guericke first demonstrated this power to Emperor Ferdinand III in 1654 when he used 30 horses and divided them into two teams of 15 horses each, each pulling a hemisphere, which could not be pulled apart! In 1656, he performed a smaller show in his hometown of Magdeburg, using eight horses, which was performed by the scientist Gaspar Schott.

Gaspar Schott) was sketched and recorded in the book "Mechanical, Hydraulic, Pneumatic".

So how do these spheres hold together, simply put, it's the atmospheric pressure! All objects in the atmosphere are constantly bombarded with air molecules in all directions, and this atmospheric pressure is not noticeable to us because our body has an internal pressure that balances it. When the two hemispheres are first put together, the air pressure inside them balances the air pressure outside, and they can be easily pulled apart.

However, when the air is removed from the inside of the hemisphere, there is no longer a force pushing outward, and the external atmospheric pressure dominates, pushing the hemispheres together and preventing them from parting.

The Magdeburg Hemispheric Laboratory extracts air from both hemispheres, and the two hemispheres are better able to squeeze together. This experiment proves the existence of atmospheric pressure.

Put the two-handled hemispheres together, drain the air inside, and then have two different teams pull the ball in different directions to prove the atmospheric pressure.

A little bit of Magdeburg, he's a smart.

Magdeburg Hemispheric Experiment. It was done by Otto von Glick.

The Magdeburg Hemisphere, also known as the Magdeburg Hemisphere, was founded in 1654 when the then mayor of Magdeburg, Otto von Glick, was in the Holy Roman Empire.

A scientific experiment conducted in Regensburg (present-day Regensburg, Germany) with the aim of proving the existence of atmospheric pressure. The experiment was also known as the "Magdeburg Hemisphere" experiment because of Glick's title.

The two hemispheres in which the experiments were conducted are still preserved in Munich.

of the Deutsches Museum. In reality, there are also replicas for teaching purposes, which are used to demonstrate the principle of air pressure, and they are also much smaller in size than the hemispheres of those days. If the hemisphere was to be vacuumed, it would take sixteen more horses to pull it apart.

Experimenter:

Otto von Glick (20 November 1602 – 11 May 1686) was a German physicist and politician who was born into an aristocratic family in Magdeburg and studied at Leibniz.

and Leiden University.

He served in the army as an engineer and was mayor of Magdeburg from 1646 to 1676. At this time, he was engaged in politics on the one hand, and on the other hand, he was engaged in the research of natural sciences. He invented the piston vacuum pump in 1650.

And using this invention, he designed and carried out the famous Magdeburg hemispheric experiment in 1654.

1.Otto von Glick was a German physicist and politician. Born into an aristocratic family in Magdeburg, he studied at the universities of Leibniz and Leiden. He served in the army as an engineer.

2.Otto von Glick invented the piston vacuum pump in 1650 and used this invention to set up a macro burn meter in 1657 and carried out the famous Magdeburg hemispheric experiment, showing the magnitude of atmospheric pressure and pushing.

3.Otto von Glick's research on atmospheric pressure was carried out independently, and it was only after he proved the existence of atmospheric pressure that he learned that Torricelli had made this discovery experimentally 11 years earlier.

4. Otto von Glick's study of vacuum and atmospheric pressure began out of curiosity, and he did not believe in the beautiful language of sophistry and argument, and asserted that "eloquence, elegant language, and the skill of argument are of no use in the field of natural science.""。

5.He invented the piston vacuum pump in 1650 and used this invention to design and carry out the famous Magdeburg hemispherical experiment in 1654.

6.The Magdeburg hemispheric experiment proved that atmospheric pressure exists and is very strong.

7.In the experiment, the air in the two hemispheres was pumped out, so that the number of air particles in the balls decreased and decreased.

8.The atmosphere outside the sphere compresses the two hemispheres together, so it is not easy to separate.

9.The more air is removed, the greater the pressure on the hemispheres and the less likely it is for the two hemispheres to separate.

The presence of atmospheric pressure is demonstrated.

On May 8, 1654, Otto Gorrick, the mayor of Magdeburg, Germany, put two hollow copper hemispheres with a diameter of more than 30 centimeters together, used an air extractor to extract the air in the balls, and then used two teams of horses to pull the two hemispheres in opposite directions. It took 16 horses to pull them apart, and when the horses tried their best to pull the two hemispheres apart at the end, there was a loud noise. This is known as the Magdeburg Hemispheric Experiment.

Magdeburg Hemispheric Experiment: The aim was to prove that atmospheric pressure exists and is large.
