How Do Microscopes Change Our Lives?

Microscopes change lives by allowing scientists to gain a better understanding of the physical world as well as the human body and the nature of various illnesses, allowing for improved technologies and innovations in the medical field. Hospitals and clinics sometimes use microscopes to more accurately diagnose illnesses in patients.

One example of an important discovery with the ability to impact lives occurred when Robert Koch, a physician, used a microscope to figure out that bacilli caused cholera and tuberculosis. Both illnesses were among the most deadly diseases at the time of the discovery, and Koch's realization was an important step in discovering how to treat both conditions.

Edward B. Lewis, Eric Wieschaus and Christiane Nüsslein-Volhard were three scientists who observed fruit flies under microscopes to gain information about the way egg cells develop into full organisms. The information they gathered was valuable in better understanding the way organisms of all species grow and develop.

Hans and Zacharias Janssen invented the first ever microscope in 1590, according to Following this initial invention, several more-advanced microscope models became available and made it possible to observe more parts of nature that were previously inaccessible to the human eye. For example, viruses, which could not be observed using earlier microscopes because they are tinier than all types of cells, are observable under scanning electron microscopes.
