Scientific Inventions

There were many inventions created during the scientific revolution, some of the greatest were the microscope, the thermometer, and the barometer.

The Microscope
The microscope was invented by a scientist named Anton van Leeuwenhoek in the 1670's. It was a brass tube with curved glass lenses inside that magnified the object under the microscope 250 to 300 times. With the microscope Leeuwenhoek could observe bacteria in fluids, and tiny blood cells. This was a great achievement that we still use all the time today, especially by scientists.

The Thermometer
The thermometer was invented by Galileo in the early 1600's to measure temperature. It was an open tube of glass with a bulb with water in it at the bottom. When the temperature got warmer, the water would raise, and when it got colder the water lowered. Galileo's thermometer influenced the creation of other thermometers and temperature measurement systems like the first mercury thermometer that used the Fahrenheit system.

The Barometer
The barometer was created by Evangelista Torricelli in 1643. It is an instrument that measures the pressure of Earth's atmosphere. Since changes in air pressure mean changes in weather, scientists later started using the barometer to predict weather. Torricelli's invention influenced the ability to predict weather, which we use all the time today.
