Where can police officers walk holding hands, thus expressing simple male friendship?

In Nepal and India, you can often see men walking down the street, including even police officers, holding hands.

They do not see anything reprehensible in such behavior - men simply denote their friendship, and not at all homosexual relationships.

Random interesting fact from the Great Encyclopedia:

By whom, when and how was the first armadillo invented?

In 1592, during the invasion of Korea, the Japanese destroyed many Korean ships. The Korean Navy at that time was commanded by Admiral Yi Sunshin.

Once he dreamed of a monster in the form of a sea turtle with the head of a dragon, which threw fire out of its mouth. No swords could pierce the shell of this tortoise.

Waking up, the admiral ordered the construction of a ship from thick pine logs, upholstered in iron armor. The bow of the ship was made in the shape of a dragon's head, and a cannon fired from its mouth. A small fleet of these first battleships in the world repulsed the enemy attack.

This is the earliest known case of an invention made in a dream.

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 ... >>

Glass recognizes the image 13.07.2019

Automatic image recognition is one of the modern topical tasks. You have to recognize a lot: from signs and text to faces and other images. As a rule, artificial neural networks are used for this, consuming significant computing and energy resources.

The idea of researchers from the University of Wisconsin-Madison was to introduce bubbles and pieces of light-absorbing materials of various shapes into the glass plate at "strategic" places. By changing the direction of light propagation, they should eventually lead to the fact that the light from the image falling on the plate will be focused or concentrated in a certain place. Each image has its own place, which allows for recognition.

To prove the concept, the researchers developed a technology for making glass plates capable of recognizing handwritten numbers. The light emanating from the image of the number, after passing through the plate, was focused on one of nine specific spots, each of which corresponded to its own number. The resulting glass pieces successfully passed the test, even being able to distinguish between handwritten 3 and 8.

Designing glass for number recognition was similar to the process of machine learning, except in this case, real material was "trained" instead of a computer program. It was necessary to calculate the places where impurities would be introduced into the glass. In fact, such an environment produces artificial neural calculations, only not digital, but analog. Although the preliminary learning process can be laborious and computationally intensive, the glass itself is then easy and inexpensive to manufacture.

The new way of performing analog artificial neural computations by propagating light in a medium has a number of advantages. These "calculations" are inherent in the material itself, so they do not require energy and do not use any electronic devices during operation. This could open up new perspectives for low power devices. Devices "glass recognition" work in real time, literally at the speed of light. The advantage of this technology lies in its ability to instantly solve recognition problems without any power consumption. In addition, a single plate of image recognition glass can be used hundreds of thousands of times.

In the future, the researchers plan to see if their approach works for more complex tasks, such as face recognition. For example, you can use such glass as a biometric lock configured to recognize the face of only one person.
