Microscopy timeline... are?
Answer (1)
Microscopy started way back—even before microscopes were officially invented. Around 710 BC, people used things like the Nimrud lens, which may have worked like a magnifying glass. Then in 1000 AD, the reading stone was created to help people see small letters better. Fast forward to 1590, when Hans and Zacharias Janssen, two Dutch spectacle makers, built the first microscope by placing lenses in a tube.In 1609, Galileo Galilei improved the design and made a compound microscope. By 1665, Robert Hooke used a microscope to look at cork and discovered “cells”—he even published a book called Micrographia. Then in 1676, Antonie van Leeuwenhoek made his own simple microscope and was the first to see living cells and bacteria.As time went on, scientists kept improving the microscope. In 1830, Joseph Jackson Lister solved blurry image problems by using weak lenses together. In 1878, Ernst Abbe created a formula to measure how clear a microscope image could be. Then in the 1900s, new types of microscopes were invented—like the electron microscope in 1938, which could see things much smaller than light microscopes could.By 1981, scientists even made microscopes that could show 3D images of tiny objects, thanks to the scanning tunneling microscope[tex].[/tex]
