How is known as the father of microscopy




















In Micrographia , Hooke presented the first published depiction of a microganism, the microfungus Mucor. There are several different types of microscopes used in light microscopy, and the four most popular types are Compound, Stereo, Digital and the Pocket or handheld microscopes.

TEAM 0. Right now, our best evidence says that there are particles inside of neutrons and protons. Scientists call these particles quarks. Our best evidence also shows us that there is nothing inside of an electron except the electron itself. Quarks combine to form composite particles called hadrons, the most stable of which are protons and neutrons, the components of atomic nuclei. Up and down quarks have the lowest masses of all quarks. Electrons have a negative charge. You are using a browser version with limited support for CSS.

Leeuwenhoek was a common man without any fortune or formal education, so he had to work for a living. Leeuwenhoek made simple one lens microscopes. He was not the first person to build a microscope, but the microscopes that he did build were the best ones for that time period.

Leeuwenhoek was the first person to describe bacteria from teeth scrapings , protozoans from pond water , helped to prove the theory of blood circulation. He gained much of his inspiration form reading Hooke's Micrographia. Anton van Leeuwenhoek — is credited with bringing the microscope to the attention of biologists, even though simple magnifying lenses were already being produced in the 16th century.

Van Leeuwenhoek's home-made microscopes were very small simple instruments, with a single, yet strong lens up to X in comparison to the 50x of contemporary compound microscopes. It took about years of optical development before the compound microscope was able to provide the same quality image as van Leeuwenhoek's simple microscopes, due to difficulties in configuring multiple lenses. Still, despite widespread claims, van Leeuwenhoek is not the inventor of the microscope but the inventor of the simple microscope which uses one magnifying lens.

However, Leeuwenhoek is commonly known as "the Father of Microscopy and Microbiology", and considered to be the first microbiologist. He is best known for his work on the improvement of the microscope and for his contributions towards the establishment of microbiology.

Using his handcrafted microscopes he was the first to observe and describe single celled organisms, which he originally referred to as animalcules , and which we now refer to as microorganisms.

He was also the first to record microscopic observations of muscle fibers, bacteria, spermatozoa and blood flow in capillaries small blood vessels. Van Leeuwenhoek did not author any books, although he did write many letters. Van Leeuwenhoek's interest in microscopes and a familiarity with glass processing led to one of the most significant developments in the history of science.

By placing the middle of a small rod of soda lime glass in a hot flame, Van Leeuwenhoek could pull the hot section apart like taffy to create two long whiskers of glass. By then reinserting the end of one whisker into the flame, he could create a very small, high-quality glass sphere.

These spheres became the lenses of his microscopes, with the smallest spheres providing the highest magnifications. An experienced businessman, Leeuwenhoek realized that if his simple method for creating the critically important lens was revealed, the scientific community of his time would likely disregard or even forget his role in microscopy.

He therefore allowed others to believe that he was laboriously spending most of his nights and free time grinding increasingly tiny lenses to use in his microscopes. Leeuwenhoek constructed hundreds of microscopes and nourished a passion for building new microscope whenever he chanced upon an interesting specimen that he wanted to preserve. Van Leeuwenhoek ground more than optical lenses.

He also created at least microscopes, of differing types, of which only nine survived. His microscopes were made of silver or copper frames, holding hand-ground lenses. Those that have survived are capable of magnification up to times. It is suspected that Van Leeuwenhoek possessed some microscopes which could magnify up to times.
