Who is the author of the microscope?

The word "microscope" is a combination of two Greek words: "micros" (small) and "skopos" (observer). Thus, "microscope" means "observer of the small". This is a device used to see tiny objects invisible to the naked eye.

Usually an object appears larger the closer it is brought to the human eye. But if you bring it closer than 25 centimeters, it becomes unclear. Then they say it's out of focus. What if a convex lens is placed between the eye and the object? Then it can be brought to the eye closer than 25 centimeters, and it will be in focus.

Today we describe it simply as "using a magnifying glass". But ordinary magnifying glasses are really "simple microscopes" and have been known as such since time immemorial. So when we talk about the invention of the microscope, we really mean "compound microscope". At present, we only mean it when we talk about a microscope.

What is a "compound microscope"? In this type of microscope, magnification occurs in two stages thanks to two lenses. One of them, called the "lens", creates the original magnified image. The other, the "eyepiece", enlarges the first image.

In fact, there are several lenses in current microscopes, used for the objective as well as for the eyepiece. But the main thing is that all these microscopes are based on the principle of two-stage image magnification. The compound microscope was discovered sometime between 1510 and 1610. There is no exact information about the author of this discovery, and it is usually attributed to Galileo. Sometimes the "father of the microscope" is called the Danish scientist Leeuwenhoek, but this is due to many of his discoveries that he made using this device.

Leeuwenhoek showed that weevils, fleas and other small creatures hatch from eggs and are not "self-generating". He was the first to see such microscopic life forms as single-celled organisms and bacteria. With the help of a microscope he built with his own hands, he was the first to see the process of complete blood circulation.

Today it is difficult for a person to do without a microscope in almost any branch of science and industry.

What were the Middle Ages?

The history of mankind is divided by scientists into three large groups - the ancient world, the Middle Ages and modern times. The Middle Ages cover the time from the fall of Rome to modern times, that is, the 476th century. When it comes to such a long period of time, it is difficult to give exact start and end dates. One era gradually passed into another. But the beginning of the Middle Ages is considered to be 1453 AD. when the last Roman emperor was dethroned. And its end is attributed to XNUMX, when Turkey captured Constantinople, the capital of the Eastern Empire.

What was life like in the Middle Ages? What important events took place during this time? This was the era of the victorious march of Christianity across Europe.

During the Middle Ages, the feudal system in Europe developed and then fell into decay, modern nations began to form. Although it was the age of knights, cruelty flourished. The lords spoke of honor and romantic belief in a dream, but at the same time treated their slaves and servants inhumanly. It was a time when people had firm faith. At no other time has religion played such an important role. Church and state were not only tied together, but often the church was the state. However, towards the end of the Middle Ages, priests began to lose their power in things that had nothing to do with religion.

Modern trade has its roots in the Middle Ages, when they were looking for new trade routes to India and China. Science did not advance significantly at this time, and most literary works were associated with chivalry and battles. The architecture of this period is represented by majestic Gothic cathedrals with stained glass windows in them.

Artificial leather for touch emulation 15.04.2024

In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>

The attractiveness of caring men 14.04.2024

The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person.
