Microscopes and Antonie van Leeuwenhoek Essay

Antonie van Leeuwenhoek is the most well-known scientist in the contribution to microbiology, he acquired the title of "father of microbiology" and has been a longtime employee to achieve the remarkable height of the accuracy of the microscope lens I am working on improving the microscope. His magnification is up to 275 times and the resolution is up to 4 microns. In addition, he was the first person to show his findings from animal and vegetable material in great detail, and observe the bacteria he discovered in the water; in the "Philosophy Trading" publication of 1683 for this bacterium Leeuwenhoek presented the first example. In this publication, Lewinhoek wrote an article about his observation inside the mouth of an elderly to a noble society. He discovered that "An incredibly wonderful living animal company (Latin" small animals ") is more flexible than before. In addition, because there are so many other small animals, every water seems alive ... "These are the first observations of living bacteria in history."

In this article I will explain the signs of unexpected life I have called Leeuwenhoek in a drop of rain, he called "small animals". He witnessed bacteriology and protozoa, laying the foundation for bacteriology and protozoa. Leeuwenhoek also found "small animals" on other waters, including the lake, and on the surface of green peppers and teeth. In addition, with regard to the article, I also begin to identify new useful information created in Leeuwen.

On October 9, 1676, e wrote as follows. "About the observation of various small animals, a large number of people were found in rainwater - seawater and snow water, and water the peppers poured into the water."

Leeuwenhoek insisted on writing and writing his observations until the moment of his death came. After the death of August 30, 1723, the pastor of the new church in Delft wrote to the Royal Society as follows.

"... Antony van Leeuwenhoek believes that the actual situation of natural philosophy is tested in the most productive way by experimental methods and is supported by sensory evidence.Hands make best effort and excellent lenses With these lenses, he discovered many secrets of nature, which is now well known throughout the world of philosophy. "

In the late sixties Antony van Leeuwenhoek grinds his lens and started making a simple microscope. Each microscope is not a compound microscope but a powerful magnifying glass. Leeuwenhoek's handmade lens can magnify objects by 200 times! He observed animals and plant tissues, sperm cells and blood cells, minerals, fossils and so on. He also discovered nematodes and rotifers (microscopic animals) that discovered bacteria when seeing plaque samples from their teeth and other teeth.

The microscope we use today is far more complicated than the microscope used by Dutch owner Antony van Leeuwenhoek in the 17th century. Despite the limits of his current ancient lens, van Leeuwenhoek observed the movement of primitive organisms (unicellular organisms) and sperm (collectively referred to as "organisms"). "In a publication called Micrographia published in 1665, Robert Hooke, an experimental scientist, has created the term" cell "to observe the box-like structure of cork tissue seen through the lens. Van Leeuwenhoek discovered bacteria and protozoans, and with the subsequent development of lenses, microscope fabrication and dyeing techniques, other scientists were able to see some of the components in the cell.

Antony van Leeuwenhoek is a Dutch zoologist born in 1632 (1723). He most clearly remembers red blood cell explanation. Van Leeuwenhoek can only draw these small structures after trying out various simple microscope designs. Simple microscope van Leeuwenhoek uses single lens metal. It has a short focal length so that the instrument must be very close to his eye, so that the object he is looking for is in focus. In his design, there are things that magnify an object by 250 times
