Introduction

In the 17th century, a striking demonstration captivated audiences and revealed the invisible power of atmospheric pressure. Otto von Guericke, a German scientist and inventor, used two bronze hemispheres sealed together with a vacuum to create an experiment that would make history. Even a team of horses pulling in opposite directions could not separate them, illustrating the immense force of air pressure.

This page explores the story behind the Magdeburg Hemispheres, their role in the scientific revolution, and how this simple yet profound experiment challenged prevailing beliefs about nature and inspired generations of scientific inquiry.

  1. What 24 horses could not accomplish, the gentle hand of the diplomat could.


This represents the justice paradox: the vacuum, the created happening that arises from dysfunctions within the justice system (as proposed on the first webpage) and the gentle hand, when in silence and in the shadows, human failings are reconciled and harmony is restored once again.

Airtight half spheres closed against each other, suitable to prove the existence of air pressure.
This experiment was first demonstrated by Otto van →Guericke, mayor of Magdeburg.

The hemispheres were placed against each other and the space within them was made airless with an air pump; it turned out that a very great force was needed to pull them apart.

Otto von Guericke, mayor of Magdeburg, demonstrated the effect of air pressure at the Regensburg Imperial Diet (1654): 16 horses were unable to pull apart two airless pumped hemispheres of 55 cm diameter.

Put hemispheres precisely together so that all edges match. Pump air out of the space between hemispheres. The inner pressure highly decreases. Because of the difference in pressure the outer air pressure highly presses hemispheres together. When the air leaks again between hemispheres, hemispheres get apart again. Otto von Guericke was the first who exposed this experiment for the emperor in Magdeburg in the year 1654. Two horse teams weren’t strong enough to separate the hemispheres. This is physics experiment for science project.

Wat 24 paarden niet vermocht, kon de zachte hand van de diplomaat.

The Magdeburg hemispheres are a scientific demonstration of the power of atmospheric pressure. The key points of the Magdeburg hemispheres are:

  1. The Magdeburg hemispheres were invented by the German physicist and inventor Otto von Guericke in 1654.

  2. The Magdeburg hemispheres are two metal hemispheres that are designed to fit together perfectly, creating an airtight seal.

  3. By using a vacuum pump to remove the air from inside the hemispheres, the atmospheric pressure on the outside of the hemispheres causes them to be held together with a tremendous force.

  4. This force is so great that even two teams of horses, each pulling in opposite directions, were unable to separate the hemispheres when von Guericke first demonstrated the experiment.

  5. The Magdeburg hemispheres were one of the first demonstrations of the power of atmospheric pressure and are still used today as an educational tool to teach about the principles of physics and air pressure.
