Who discovered medicine?

The first person to help someone feel better can be called the first doctor. For example, a person who pulled a splinter out of someone's finger did what a doctor does. Primitive people used a kind of medicine that we can call magic. They used spells, or songs, or decoctions of herbs and leaves. By chance, they may have discovered that the heat of a fire relieves sprains in the shoulder, and that warm drinking of herbs helps with stomach pains.

Many primitive peoples still today correct a dislocation in this way, or splint a broken bone, or use plants that have laxative properties or can put people to sleep. Doctors appeared in early civilizations. The Babylonians left many medical books, with such clear descriptions of various diseases that physicians today can recognize them.

The ancient Egyptians used medical treatment and gave the sick pills, ointments, medicines containing drugs. They even performed surgical operations on the external organs of the body. A man named Aesculapius was the first physician in Greek history. He used mainly magical medicine. But gradually true medicine began to develop.

A man named Hippocrates who lived around 400 B.C. BC, did so much to rid medicine of magic and superstition that he was called the "Father of Medicine". In his books, he taught that the doctor should carefully and carefully examine the patient. He should apply gentle treatment and try to maintain natural healing. A doctor should never harm a patient. He must keep medical confidentiality. Hippocrates also discovered and described many diseases.

Some of his medical findings are as relevant today as they were over 2 years ago. So, we can call him the first doctor in the world in the sense that we put into this word today.

Random interesting fact from the Great Encyclopedia:

Why do birds sing?

The bird songs and calls we hear in the spring are part of their love games before mating. Males sing to attract the attention of females. When the male and female find each other, he begins to ruffle her feathers and sing even louder. Females of some breeds of birds answer the male with their songs.

Not all birds are songbirds. There are some, like the stork and the pelican, that seem to have no voice at all. The vocal organs of birds are slightly different from ours. In humans, the vocal cords are located in the larynx, at the top of the windpipe. The simple membrane of birds is located at the bottom of the windpipe, in a part of the body called the lower larynx. This membrane vibrates.

The reason that different breeds of birds sing differently from others lies precisely in the shape of the lower larynx, in the number of muscles that set the membrane in motion. Birds make other sounds besides singing. They exchange cries, signals, disturbing sounds, while understanding each other. If a snake appears near the nest, the bird resorts to an alarm signal. At this signal, flocks of birds flock to her for help.

Birds use various signals and sounds all year round, and they sing only during the nesting period. Bird singing differs in pitch, rhythm, quality. The thrushes are recognized as the leaders in the creation of "real" songs.

Machine for thinning flowers in gardens 02.05.2024

In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers. ... >>

Advanced Infrared Microscope 02.05.2024

Microscopes play an important role in scientific research, allowing scientists to delve into structures and processes invisible to the eye. However, various microscopy methods have their limitations, and among them was the limitation of resolution when using the infrared range. But the latest achievements of Japanese researchers from the University of Tokyo open up new prospects for studying the microworld. Scientists from the University of Tokyo have unveiled a new microscope that will revolutionize the capabilities of infrared microscopy. This advanced instrument allows you to see the internal structures of living bacteria with amazing clarity on the nanometer scale. Typically, mid-infrared microscopes are limited by low resolution, but the latest development from Japanese researchers overcomes these limitations. According to scientists, the developed microscope allows creating images with a resolution of up to 120 nanometers, which is 30 times higher than the resolution of traditional microscopes. ... >>

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

Basis for ReRAM memory chips with a density of 100 Gbit 28.06.2017

Sony Semiconductor Solutions talked about developments related to ReRAM memory, which combines the advantages of DRAM and NAND.

Key technologies developed by Sony specialists will enable the production of high-density ReRAM memory chips.

The memory, created by Sony Semiconductor Solutions, uses copper ions. The cell design includes only one sample element and one resistive element (1S1R structure). This makes it possible to manufacture memory in the form of a simple matrix of intersecting lines and arrange such matrices in several layers, increasing the density.

One of the new developments is a barrier between the ion reservoir and the electrolyte, which reduces the uneven resistance. Due to it, it is possible to increase the storage density.

The second technology is the doping of the sampling element with boron and carbon, due to which the leakage current is reduced and the resource is increased.

According to Sony Semiconductor Solutions, the developed technologies will make it possible to produce ReRAM memory with a write time of 100 ns, a resource of 10 million cycles and a density of about 100 Gbps.

ReRAM is expected to fill the gap between DRAM and NAND in terms of cost, performance and integration.
