How did the microscopes get invented?

The invention of the telescope.

— More than 400 years ago in Holland Zacharias Jansenn made lenses for eyeglasses. Some of his lenses made things look bigger. He found that he could put two lenses together to make things look a lot bigger. So, in about 1593 Zacharias built the first microscope (“micro” means “small”, “scope” means “to see”).

Several different people say they have invented the telescope. Many historians believe it was invented in 1608 by Hans Lippershey who made glasses in Holland.

He discovered that by placing two lenses inside a tube, distant objects seemed to be much closer.

After the 1-st telescope invention much more powerful telescopes have been developed: radio, X-ray, and gamma-ray telescopes helped us to learn about Solar System, the Milky Way and the universe itself.

The Great Italian scientist Galileo Galilei (1564—1642) with the help of telescopes discovered Jupiter’s four largest satellites, spots on the Sun, hills and the phases of Venus.

The first microscope made things look 20 to 30 times larger than they are.

Another man who lived in Holland, Anton Leeuwenhoek made microscopes that could magnify objects up to 200 times. He was the first man to see bacteria!

The telescope is the most important tool for investigating astronomy.
