What functions did ancient and medieval scientists attach to the brain?

The body placed inside the human skull, most of the ancient philosophers did not attach much importance. Aristotle (384-322 BC) believed that the brain was designed to cool the blood in case it overheated. Herophilus, a physician and anatomist from Asia Minor, who worked in Alexandria a little later (about 300 BC), already considered the brain as the seat of the mind.

However, the erroneous ideas of Aristotle, who enjoyed great authority, dominated anyone's opinion. As an organ responsible for the emotions and personal qualities of a person, ancient and medieval thinkers usually considered either the heart, or the liver, or the spleen.

From here came such expressions as "broke the heart", "bilious man", etc.

Why is the clipper ship Cutty Sark famous?

Clippers are high-speed sailing vessels with unusually developed sailing equipment and a hull that "cut" the water. In the middle of the XNUMXth century, a struggle broke out between English and American clippers for the right to transport tea from China. This is how tea races were born.

The fastest clippers were Cutty Sark and Thermopylae. In the 1872 race, the Cutty Sark was seven days behind its competitor due to a broken rudder. And yet this clipper once set an absolute speed record, though not on a tea line. In 1887, this wool clipper ship sailed from Sydney, Australia to London in just 70 days. The record was not broken by anyone, and since then "Cutty Sark" has been called the queen of the oceans.

The clipper "Cutty Sark" has an unusual fate. It did not sink or disappear at sea, was not dismantled, and in 1954 was placed in eternal parking in the dry dock of Greenwich. Now the ship is one of the main attractions of the UK.

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 ... >>

Not only warming 21.06.2011

As you know, when fuel is burned, carbon dioxide is released, which contributes to global warming. Less attention is paid to the fact that when oil, gas and coal are burned, water is also produced - from the hydrogen included in these fossil fuels. Is there a lot of it?

Australian physicist David Williams became interested in this issue. According to his calculations, in the entire history of mankind until 2000, 335 cubic kilometers of water went into the air with the smoke of combustible fossils. Considering that it was distributed over the oceans, seas and lakes (the total surface is about 360 million square kilometers), their level increased by about 0,95 millimeters.

By the end of the XNUMXst century, this increase in the level due to the burning of hydrocarbons will be about four millimeters.
