The Magdeburg hemispheres experiment is a famous physics experiment that was first performed around 1650 by Otto Von Guericke in the German town of Magdeburg. Otto Von Guericke was a physicist. His intention was to demonstrate the Earth’s enormous atmospheric pressure. He constructed two half spheres that perfectly fitted to form a complete sphere with a radius of about 250 mm. With a self-designed but still primitive vacuum pump, most of the air was pumped out of the sphere. Under these circumstances, the atmospheric pressure on the outside of the sphere firmly kept the two halves together. He then went on to show that 2 teams of 8 horses could not pull these two halves apart. In a later attempt, even 20 horses were unable to overcome the atmospheric pressure.

How to use vernier caliper

• The vernier caliper is an extremely precise measuring instrument; the reading error is 1/20 mm = 0.05 mm.
• Close the jaws lightly on the object to be measured.
• If you are measuring something with a round cross section, make sure that the axis of the object is perpendicular to the caliper. This is necessary to ensure that you are measuring the full diameter and not merely a chord.
• Ignore the top scale, which is calibrated in inches.
• Use the bottom scale, which is in metric units.
• Notice that there is a fixed scale and a sliding scale.
• The boldface numbers on the fixed scale are centimeters.
• The tick marks on the fixed scale between the boldface numbers are millimeters.
• There are ten tick marks on the sliding scale. The left-most tick mark on the sliding scale will let you read from the fixed scale the number of whole millimeters that the jaws are opened.
