According to (University of Chicago, 2016), the microscope has been one of the greatest inventions in the history of science and has had the most impact on the course of science. Ever since the first microscope was invented in 1590, they have improved our knowledge in basic biology and research, as well as many other things, all of which are important. The smallest object a human can see with the naked eye is 0.2 mm, for example, algae cells. The light microscope, however, allows us to see things almost 1000 times smaller than what the eye can see, like plant, animal, and bacteria cells.
