The Compound Microscope

Optics began with Plato and Aristotle It was advanced in the Islamic Golden Age. Arabic Treatises permeated European universities after 1088 AD. Robert Grossest and Bacon promoted scientific interest in light. Compound microscopes use multiple lenses to produce magnification. A magnifying glass is a simple microscope.

A handful of conflicting intention claims arose by the Duch around 1509. Galileo invented an improved telescope in 1609. By 1624 Galileo had developed his own compound Galileo was responsible for the microscope’s name. Antoine Van Leev Wenheek popularized the and became the “father of microbiology.

Telescopes magnify for away objects. They improve our ability to peer into the cosmos. The telescope spread quickly because of cultural interest in astronomy.
