In the 16th century,a man made a magnifier composed of a single convex lens. This led to the development of the microscope.
Some of the early pioneers that invented the microscope are the Diggers of England, Hans and Zchorisas Janssen of Holland.
The effects of the microscope are still lasting and they will keep lasting until we no longer need it. It helped us learn about the blood stream of humans, animals, and insects. It has helped us learn new and amazing things about the body of animals and the life of the cells.
The microscope has lasted about 500 hundred years and will keep lasting for about 500 more years or until we discover something better.
