microscopes
how have they impoved
14th century – The art of grinding lenses is developed in Italy and spectacles are made to improve eyesight.
1981 – Gerd Binnig and Heinrich Rohrer invent the scanning tunneling microscope that gives three-dimensional images of objects down to the atomic level.

Simple microscopes include magnifying glasses and jeweler's loupes. An optical microscope with two lenses is known as a compound microscope. The basic parts of a compound microscope are the objective, which holds the lens near the specimen, and the eyepiece, which holds the lens near the observer.A microscope is a scientific instrument. It makes small objects look larger. This lets people see the small things. People who use microscopes commonly in their jobs include doctors and scientists. Students in science classes such as biology or chemistry also use microscopes to study small things.
The earliest microscopes had only one lens and are called simple microscopes. Compound microscopes have at least two lenses. In a compound microscope, the lens closer to the eye is called the eyepiece. The lens at the other end is called the objective. The lenses multiply up, so a 10x eyepiece and a 40x objective together give 400x magnification.
Microscopes make things seem larger than they are, to about 1000 times larger. This is much stronger than a magnifying glass which works as a simple microscope.

interesting facts
1.The earliest microscopes were known as “flea glasses”
2.robert hooke discovered cells by studing the honeycomb structure of a cork under a microscope.
3.Microscopes make things larger than they are, from 10 times larger to about 1000 times larger. this is much larer than an magnifying glass
4.In a compound microscope, the lens closer to the eye is called the eyepiece. The lens at the other end is called the objective.
5.The earliest microscopes had only 1 lens and are called simple microscopes. Compound microscopes have at least 2 lenses
6.A microscope is a scientific instrument that makes things normally too small to see look bigger, so they can be seen better and examined correctly. People who use microscopes commonly in their jobs include doctors and scientists.
