Otto von Guericke/Inventions
The German scholar Otto von Guericke (1602-1686) is regarded as one of the most prominent figures of the scientific revolution in the 17th century. A politician, physicist, engineer, and natural philosopher, von Guericke invented the world’s first air pump in 1650.

Why did Otto von Guericke invent the vacuum 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 year did Otto von Guericke disprove Aristotle’s theory?

In 1650, Otto von Guericke, stimulated by the work Galileo and Torricelli, to further disprove Aristotle’s supposition that nature abhors a vacuum, constructs the world’s first-ever vacuum pump and uses it to unite the Magdeburg Hemispheres.

Who invented Magdeburg 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.

Why do Magdeburg hemispheres stick together?

So how do the spheres stay together? Simply put: atmospheric pressure! A suction cup gets its sticking force by the same action as the Magdeburg hemispheres: when one pushes the cup against a smooth wall, one forces the air out of the cup, allowing atmospheric pressure to hold it to the wall.

Who of the philosophers is the founder of engineering mechanics and inventor of water pump?

Otto von Guericke, (born Nov. 20, 1602, Magdeburg, Prussian Saxony [now in Germany]—died May 11, 1686, Hamburg), German physicist, engineer, and natural philosopher who invented the first air pump and used it to study the phenomenon of vacuum and the role of air in combustion and respiration.

Why was the air pump invented?

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.

How do Magdeburg hemispheres 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. The spheres thus pull apart with nearly no resistance.

Does pressure increase with height?

Atmospheric pressure decreases as the height of a surface above ground level increases. This is because, as the altitude increases: This is why aircraft that fly at high altitudes must be pressurised.

Can Crusher experiment explained?

A can is crushed when the pressure outside is greater than the pressure inside, and the pressure difference is greater than the can is able to withstand. When the water vapor condensed, the pressure inside the can became much less than the air pressure outside. Then the air outside crushed the can.

Who is the first mathematician in world?

One of the earliest known mathematicians were Thales of Miletus (c. 624–c. 546 BC); he has been hailed as the first true mathematician and the first known individual to whom a mathematical discovery has been attributed.
