What saying of Plato was Diogenes trying to refute by bringing him a plucked rooster?

The disciples of the ancient Greek philosopher Plato once asked him to give a definition of man, to which he replied: "Man is an animal on two legs, devoid of feathers." However, after Diogenes of Sinope brought a plucked rooster to the Academy and presented it as a Platonic man, Plato had to add to his definition: "And with flat nails."

Random interesting fact from the Great Encyclopedia:

Are the temperatures the same at the North and South Poles?

For most of us, the North and South Pole regions are mysterious. We just have vague ideas about what they represent and think that they are probably very similar to each other.

But, surprisingly, there are more differences between the Antarctic (South Pole region) and the Arctic (North Pole region) than similarities. The South Pole region is mostly occupied by a continent called Antarctica. This ice and snow covered continent is almost twice the size of the United States. Conversely, the area of the North Pole is occupied by the Arctic Ocean, which washes the shores of North America, Europe and Asia.

Another difference is that people, animals and plants gradually moved north, towards the North Pole, gradually adapting to polar conditions. And in the region of the South Pole, separated by hundreds of kilometers of the surface of the oceans from the rest of the continents, with the exception of South America, neither animals nor humans can exist.

Of the vegetation, only lichens, mosses, herbaceous plants and some types of flowers are represented.

By the way, one of the reasons why the penguins successfully mastered this area is the absence of enemies here.

What is the climate like in Antarctica? Its two main characteristics should be noted: low temperatures even in summer and the strongest winds in the world. And in the region of the North Pole, air currents, rising from the surface of the surrounding ocean, slightly increase the temperature. In Antarctica, where the main part of the continent is covered with ice, cold air masses with high pressure are formed. Therefore, the climate here is more severe than at the North Pole.

Even during the summer months, the average temperature in Antarctica is below freezing! On some days the temperature can rise above 4 °C, but in the middle of summer there are days with temperatures below zero. In winter, the average temperature in the area of the South Pole is -23-35 °C.

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 ... >>

A frost-resistant kiwi variety has been developed 27.05.2019

Heinrich Straton, a well-known Ukrainian researcher, harvested the first harvest from the kiwi variety he bred - Gold Kiwi. The fruits were obtained on four-year-old trees.

At the moment, the variety continues to be tested. In the conditions of the Ukrainian winter (the experiment was carried out in the village of Storozhnitsa near Uzhgorod), the new kiwi variety withstood 22 degrees of frost in open ground without damage.

As Heinrich Straton noted, so far the weight of the fruit has been fixed at 40-50 grams. Whether this is a varietal feature of Gold Kiwi is impossible to say yet. The researcher admits that the reason for the relatively small weight lies in the conditions of development - soil, age, pollination, etc.

Straton's kiwis are distinguished by an unusual yellow tint, and an uncharacteristic taste for green fruits. Obviously, the increased content of carotenoids affects.
