Focus Description:

Any of those present conceives their favorite number. The magician asks him to multiply the number 15873 by his favorite number multiplied by 7.

For example, if your favorite number is 5, then let him multiply by 35. You will get a product written only with your favorite number. The second option is also possible: multiply the number 12345679 by your favorite number multiplied by 9, in our case this number is 45.

Focus secret:

If you multiply 15873 by 7, you get 111111, and if you multiply 12345679 by 9, you get 111111111.

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 ... >>

quantum integrated circuit 30.06.2022

Australian developers reported significant progress in the development of quantum computers. Based on almost 20 years of scientific work by Australian teams, a young company from Australia - Silicon Quantum Computing (SQC) - was able to create the world's first quantum integrated circuit. The chip is able to simulate the behavior of just one molecule - polyacetylene, but it does it much better than classical computers.

Designed and manufactured in Sydney, SQC's Quantum Processor is an analog solution for simulating the quantum states of molecules. The company still only dreams of a real quantum processor with the ability to correct errors. But even the molecular simulator promises a breakthrough for the field once such chips are commercially produced.

A quantum chemical compound simulator will help you discover unusual materials and substances for pharmaceuticals and industry. Now we cannot even imagine what properties these materials will have, because such calculations are either impossible on a conventional computer, or will take years, centuries, and even longer as the connections become more complex.

The creation of the first SQC quantum integrated circuit required the implementation of three separate technologies. First, it was necessary to create elements of atomic size so small that their energy levels would equalize, and electrons could easily pass through them. Secondly, it was necessary to implement the possibility of adjusting the energy levels of each element separately, as well as all elements together, in order to control the passage of quantum information.

Finally, it was important to learn how to control the distance between the elements with an accuracy of less than a nanometer, so that the elements remained close enough to each other, but this would not interfere with the quantum coherent transfer of electrons along the chain. All three technological tasks were successfully solved and, as the developers emphasize, this happened two years ahead of schedule.
