What is Otto von Guericke 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.
When was Otto Guericke born?

Why did von Guericke believe he had made a vacuum?
Or is space completely free from all matter, a vacuum?” As we’ll see, Guericke believed, with good reason, that space is a vacuum. He explained that in his “horses and hemispheres” experiment, the horses could not pull the hemispheres apart because the weight of the whole sky was pushing them together.

Why were the horse unable to pull apart the Magdeburg hemispheres?
The Magdeburg hemispheres are a pair of large copper hemispheres, with mating rims. When the rims were sealed with grease and the air was pumped out, the sphere contained a vacuum and could not be pulled apart by teams of horses in a famous first public demonstration in 1654.
Why are we not crushed by the atmospheric pressure?
Air does not crush you down. Fortunately, there is typically just as much pressure inside your body pressing outward as there is air pressure outside your body pushing inward. They typically cancel out, meaning that there is no overall force on you and you don’t get crushed.

What did von Guericke?
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.
Can you separate two hemispheres of all the air is sucked out from them?
No, we can not separate the hemisphere if all the air is sucked. It is because when we suck out all air from inside then there create vacuum and thus the pressure differcnce create equal to atmospheric pressure .
What happens to a sealed metal can when the air is removed from it?
The water gas molecules will occupy all the space inside the can since the air molecules have been pushed out. Since the air pressure outside the can is stronger than that inside the can, it causes the can to collapse.
How much does all the air in the world weigh?
The total mass of Earth’s atmosphere is about 5.5 quadrillion tons, or roughly one millionth of Earth’s mass.
