Who is Leke Huwen? What kind of person is Leeuwenhoek

Leeuwenhoek was born in 1632 in the Dutch city of Delft and never received formal scientific training. But he was a man with a strong interest in novelties. Once, he heard from a friend that an optician, in Amsterdam, the largest city in the Netherlands, could polish a magnifying glass, and with a magnifying glass, he could see things that were not visible to the naked eye.

He was curious about this magical magnifying glass, but he couldn't afford it because it was too high. Since then, he has often been in and out of the optical shop, carefully observing the work of grinding lenses, and secretly learning the technique of grinding lenses.

Hard work pays off. In 1665, Leeuwenhoek finally made a small lens with a diameter of only centimeters, made a frame, mounted the small lens on the frame, and attached a copper plate under the lens, on which a small hole was drilled, so that the light could shine from it and reflect what was observed. In this way, Leeuwenhoek's first microscope was successful.

Thanks to his mastery of polishing high-magnification lenses, he was able to create a microscope with a magnification that surpassed any microscope available in the world at the time.

Leeuwenhoek didn't stop there, he continued to work on improving the microscope and further improving its performance in order to better observe and understand the mysterious microscopic world. To this end, he quit his job and devoted himself to the development of microscopes. A few years later, he finally made a microscope that could magnify objects 300 times.

On a rainy day in 1675, Leeuwenhoek scooped a cup of rain from the yard and looked at it with a microscope. He noticed that there were many small, strangely shaped creatures wriggling in the droplets, and the number was staggering. In a single drop of rain, these small creatures were many times more numerous than the whole of the Netherlands at that time.

Later, Leeuwenhoek used a microscope to discover red blood cells and yeast. In this way, he became the world's first discoverer of the microbial world, being absorbed as a member of the Royal Society.

The invention of the microscope and Leeuwenhoek's research work laid the foundation for the development of biology. Using microscopy, it was found that various infectious diseases are caused by specific bacteria. This has led to successful health check-ups against disease, vaccinations, and drug development.

Leeuwenhoek is said to be a man who kept his inventions secretive. Until now, microscopists have not been able to figure out how he managed to achieve such good results with that primitive tool.

Leeuwenhoek, a Dutch microscopist and pioneer of microbiology, was born and died in Delft, the Netherlands. Thanks to his diligence and his own unique talent, he sharpened lenses far beyond those of his contemporaries.

He is very interested in the microscopic world under a magnifying lens, and observes a wide range of objects, mainly crystals, minerals, plants, animals, microorganisms, sewage, insects, etc. In 1674 he began to observe the sedan and protozoa, what he called "very tiny animals." He also measured their size.

He was the first to see bacteria and protozoa with a magnifying lens. Despite his lack of formal scientific training, his meticulous observations, precise descriptions, and numerous astonishing discoveries of tiny worlds invisible to the naked eye laid the foundation for the development of bacteriology and protozoan almanacs in the 18th and early 19th centuries.

His images based on microorganisms seen with a simple microscope still appear to be correct today.

Due to the weakness of the basic knowledge, the content of his report was limited to a few observed facts, and failed to rise to the level of theory. His microscope methods are also kept secret, and some of them are still unsolved mysteries. He made lenses as small as a needle.

The maximum magnification of the appropriate lens can be up to 300x.

Antony van Leeuwenhoek (24 October 1632 – 26 August 1723) was a Dutch microscopist and pioneer of microbiology, born and died in Delft, the Netherlands.

In 1648 he became an apprentice in a cloth shop in Amsterdam. At the age of 20, he returned to Delft to sell his own silk cloth. After middle age, he was assigned by the mayor of Delft to work in municipal affairs.

This kind of work is very rewarding and easy, and gives him more time to work on the work of grinding lenses, which he has loved since childhood, and to observe the subtle objects of nature. Due to his diligence and his own unique talent, he sharpened his lenses far beyond those of his contemporaries.

There are many forms of magnifying lenses and simple microscopes, and the materials of lenses include glass, gemstones, diamonds, etc. He honed more than 400 lenses in his lifetime, and there is a simple convex lens with a magnification of 300 times!

Leeuwenhoek was Dutch. He was born into a very poor family, and when he was very young, his father died early because he could not afford medical treatment. In his childhood, he wandered around in order to make ends meet.

At the age of 16, he was apprenticed to a grocery store, working 12 hours a day. However, he was very ambitious and refused to bow to the fate of suffering. He tried his best to learn knowledge and skills.

Every night, in the dim light, I open the books I borrowed from others, and study hard and earnestly on my own.

The neighborhood of this grocery store is an optical store. Leeuwenhoek often saw people in the opticians grinding lenses, and he gradually became interested in lenses. Whenever he had time, he went to the optical shop to observe the grinding of lenses, and sometimes tried to sharpen them, so that he gradually mastered the technique of grinding lenses.

At the same time, he also learned what kind of lenses can make people see things bigger, and what kind of lenses can make people see things in the distance.

After five or six years, Leeuwenhoek's grocery store went out of business. Leeuwenhoek lost his job and went back to living a wandering life. Later, he found a job as a gatekeeper for the city, and his life was stable.

He is in a position to study again. On the one hand, he studied cultural knowledge on his own, and on the other hand, he carefully and meticulously polished his lenses. At this time, he had a desire to make an instrument that could magnify objects and observe small things that could not be seen with the naked eye.

Of course, it was not easy to create such an instrument. With his own hands, he grinds little by little like an "iron pestle sharpening needle". I don't know how many times I have failed, I don't know how many sleepless nights I have spent, I don't know how many blood blisters have been ground on my hands, I don't know how many people have ridiculed me, but in the end, I finally succeeded, and a high-precision lens of fully qualified quality was successfully completed.

The success of the lenses allowed Leeuwenhoek to complete the most basic work of the instrument he envisioned. With joy in his heart, he mounted the high-precision lens on a metal plate and installed the screw rod to adjust the lens. Thus was born the world's first microscope.

Demographed by the great success of this instrument, Leeuwenhoek became one of the most prominent figures in the history of microscopy. His success is due to his skill in sharpening lenses (he can magnify them up to 300 times) and his perseverance in creating microscopes. The advent of the Leeuwenhoek microscope opened the door to the study of microbiology and opened a new era of human conquest of infectious diseases.
