Who invented the microscope for the first time
Such a device as a microscope, both before and in the modern world is very popular. Each of us since the school times well remembers that this is an optical device that increases the objects in hundreds, and even thousands of times. At the lessons of biology, we looked through the eyepiece to the cells of the onion film and were surprised at the cleverness and complexity of such a device. Today we will try to understand who invented the microscope, since there is as yet no exact answer to this question.
How did the first microscope appear?
The optical properties of curved surfaces were discovered back in the 300's BC. Euclid, in his treatises, described the studies carried out, explaining the refraction and reflection of light, as a result of which a visual increase in objects occurred. Ptolemy in his work "Optics" described the characteristics of flammable glasses. But at that time all these properties did not find application. And only after several centuries they were used in practice.
17th century - the time of great discoveries
In this century, a real scientific and technological revolution took place, which became the foundation of most modern sciences: biology, medicine, physics, mathematics. Grandiose discoveries and great inventions were made. Just at that time, the microscopes improved significantly and became an important part of every researcher. But no one really said who invented the microscope, whom to consider it the creator. According to one of the opinions, the creator of the device under consideration is A. Kircher, who in 1646 described a device called "flea glass". What did it consist of?
The eyewear system of K. Huygens and the further development of the device
The creation of this system was a big step in the development of microscopes. It was possible to obtain a colorless image, which made it possible to increase the clarity of the subjects studied. Scientist K. Drebel in the early 17th century made a complex microscope consisting of two lenses: the first is facing the object, the second - to the eye of the researcher.
Influence of the microscope on microbiology
Using his lenses, Levenguk created his own device and began to study various objects. So, just through one small sized spherical lens, he saw in a drop of dirty water a lot of living beings of the smallest size. It was concluded that there is some kind of microscopic life. Levenguk engaged in its study, which marked the beginning of yet another new science - microbiology. In 1861, the scientist presented his discovery to the Royal Society of London and received the title of inventor of microscopes and the greatest researcher.
Electron microscope
If you ask yourself who invented the electron microscope, then the correct answer would be: physicists from Sheffield University. At the heart of the old device is the method of transmission microscopy, which allows obtaining image resolution limited only by the wavelength of an electron. In the construction of the translucent device, the researchers abandoned the magnetic lenses, since they basically reduced the resolution.
The principle of the electron microscope
Now it's not so important who invented the microscope for the first time. Now the ball is governed by completely different, much more powerful devices, including electronic ones. According to the principle of work, they are similar to light ones. Only in them instead of a light stream through the sample electrons pass, and magnets are used instead of glass lenses.
Who invented the light microscope? A bit of history
What is an optical microscope? This is a laboratory system designed to obtain images of small objects in an enlarged form for the purpose of their study, consideration and practical application. We began our article with the history of the development of the microscope, now we will look at this question from the other side. At present, such a device is necessary not only for doctors and biologists.
Let's talk about one achievement. In 2006, German scientists Mariano Bossi and Stefan Hell developed a nanoscope - a super-powerful optical microscope, which allows you to explore objects of a super-small size of 10 Nm, and also to obtain 3D images of the highest quality.
Briefly about the possibilities of modern devices
We have sorted out a little with the question of who invented the first microscope. And now literally a few words about the possibilities of modern instruments. In 2010, from the Israeli Yeshiva University came the news that scientists were able to trace how individual molecules move inside the cell. At the same time, German researchers captured molecular transformations in the course of chemical reactions. A year earlier, a clear image of a single atom was obtained at the Kharkov Institute of Physics and Technology.
