Antony van Leeuwenhoek is best known for discovering bacteria and creating more than 500 simple microscopes. He also discovered sperm cells, blood cells, protists and microscopic nematodes.Continue Reading
Antony van Leeuwenhoek made one of the first recorded observations of bacteria when he studied the plaque from his teeth and the teeth of several other people. He noticed "animalcules" swimming in the saliva sample.
His simple microscopes were very different from the compound microscopes used today. They had one lens and a brass plate, and the lens was adjusted by turning two screws. Only about 10 of these simple microscopes are still in existence today.
Although van Leeuwenhoek never received a degree or any formal scientific training, he was elected a member of the Royal Society of London in 1680.Learn more about Biology
Monocular microscopes, or single-eyepiece microscopes, are often used to study very small objects and organisms that can't normally be observed by the naked eye, such as cells, fungi and bacteria. These microscopes feature a magnification power typically ranging from 40x up to 1400x.Full Answer >
Anton Van Leeuwenhoek, known as the father of microbiology, was the first to observe bacteria in 1676. He used one of the first compound microscopes and found what he called "cavorting beasties" in pond water.Full Answer >
Caesar told Marc Antony, who is running in the Lupercalia celebrations, to touch Calpurnia, Caesar's wife, as he passes by. The Romans believed that women touched or whipped during this celebration would become fertile.Full Answer >
Dissecting microscopes are low-magnification microscopes that can focus on a three-dimensional object that is too thick to be viewed in a regular compound microscope. Dissecting microscopes are also called stereo microscopes as they are designed to allow three-dimensional objects to be seen in three dimensions.Full Answer >
