What country invented Chinese fortune cookies?

For dessert, Chinese restaurants in the United States and many other countries serve fortune cookies - slips of paper inside containing wise phrases in Chinese with translation or numbers, which many then transfer to lottery tickets. However, in China itself, these cookies are practically unknown, and the Chinese have nothing to do with their origin. The prototype of these sweets originated in the 19th century in Japanese temples, and it was Japanese immigrants who adapted the cookies for the American market. According to one version, it began to be strongly associated with China when, during the Second World War, Japanese-Americans moved en masse to concentration camps, and the Chinese picked up the production of cookies.

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 ... >>

Moon origin modeled 10.12.2020

The hypothesis of the origin of the Earth's satellite as a result of the collision of two planets was tested using a new algorithm.

British scientists believe that the Moon could have formed about 4,5 billion years ago as a result of a collision of the Earth with the hypothetical planet Theia.

Theia is a hypothetical planet that formed 4,6 billion years ago, like other planets in the solar system, which could have been similar in size to Mars. She is named after Theia, one of the Titanide sisters in ancient Greek mythology, the mother of Helios, Eos and Selene (the moon goddess).

Interest in impact theory has grown due to the recent discovery of heterogeneity in oxygen isotopes in lunar samples.

The scientists simulated the alleged collision between the proto-Earth and Theia and studied the effect of different rotation speeds of the hypothetical planet on the impact that forms the Moon.

It is emphasized that the conclusions are not the final proof of the origin of the Moon, however, they are an important step in understanding how the Earth's satellite could have formed.
