History of Microscopes and Bacteria

The First MicroscopeFor many years, man had wanted to observe things closer than the naked eye, so man created the Microscope.Curved glass lenses had been used by the Romans and they found the object slightly larger, when looking through the lenses.

There are many types of bacteria, some helpful to us and some bad. Bacteria is everywhere, in food, on objects, even in you!

Bacteria

In the 1590's two dutch specticle makers, played around with these glass lenses. Zacharias and Hans Janson made the first microscope by attaching two curved glass lenses to a long metal tube. This microscope was not used for scientific purposes as it blurred the object.

In the late 17th century, Anton van Leeuwenhoek was the first man to create a proper microscope. He polished 50 lenses and put them together and created a microscope with magnification power of 270x. He made many biological discoveries with this microscope.

First Magnification

Now we have great modern microscopes that help us view many cells up close.These microscopes, used by scientists in modern labs today, have all come from Zacharias Janson. Without them, we wouldn't know many of the things we know today.

Modern Microscopes

Streptococcus thermophilus is a beneficial bacteria found in yohurt, mozerella cheese and other dairy products. It is also found that it improves bad breath!

Ever heard someone say to eat yohurt when your sick? Streptococcus thermophilus helps cramps, nausea and helps your digestive system.
