Comments on the article

To obtain green mordant for zinc items you need to dissolve 50 parts of sodium sulphate (hyposulfite) in 500 parts of boiling water, add 25 parts of sulfuric acid, filter (to separate the settled sulfur) and immerse zinc things in the solution, which very quickly become covered with a light green bloom.

If you keep things in the solution for a longer time, then the light green color turns into dark green. But for this kind of coloring, it is best to coat the zinc things with copper beforehand and then treat them as with copper.

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 ... >>

The threat of space debris to the Earth's magnetic field 01.05.2024

More and more often we hear about an increase in the amount of space debris surrounding our planet. However, it is not only active satellites and spacecraft that contribute to this problem, but also debris from old missions. The growing number of satellites launched by companies like SpaceX creates not only opportunities for the development of the Internet, but also serious threats to space security. Experts are now turning their attention to the potential implications for the Earth's magnetic field. Dr. Jonathan McDowell of the Harvard-Smithsonian Center for Astrophysics emphasizes that companies are rapidly deploying satellite constellations, and the number of satellites could grow to 100 in the next decade. The rapid development of these cosmic armadas of satellites can lead to contamination of the Earth's plasma environment with dangerous debris and a threat to the stability of the magnetosphere. Metal debris from used rockets can disrupt the ionosphere and magnetosphere. Both of these systems play a key role in protecting the atmosphere and maintaining ... >>

Solidification of bulk substances 30.04.2024

There are quite a few mysteries in the world of science, and one of them is the strange behavior of bulk materials. They may behave like a solid but suddenly turn into a flowing liquid. This phenomenon has attracted the attention of many researchers, and we may finally be getting closer to solving this mystery. Imagine sand in an hourglass. It usually flows freely, but in some cases its particles begin to get stuck, turning from a liquid to a solid. This transition has important implications for many areas, from drug production to construction. Researchers from the USA have attempted to describe this phenomenon and come closer to understanding it. In the study, the scientists conducted simulations in the laboratory using data from bags of polystyrene beads. They found that the vibrations within these sets had specific frequencies, meaning that only certain types of vibrations could travel through the material. Received ... >>

AI beat a human at poker 09.03.2017

Matej Moravcik of the University of Alberta and other members of an international team of scientists from Canadian and Czech academic institutions have developed an artificial intelligence system that can beat a human in the most difficult version of poker known as Texas Hold'em. This is a complex game, the number of possible moves in it reaches 10160.

A feature of poker in terms of AI work is unequal access to information. For example, in the case of chess, all players see the same pieces on the board, while in a card game the distribution of information at each moment of time is asymmetrical - only the player himself knows his set of cards.

DeepStack - as the new system is called - beat 10 out of 11 and professional players in more than 3000 games. Strictly speaking, he beat the 11th, only the advantage is not big enough. Before each move, the AI recalculated the strategy of the game, subject to restrictions on the depth of calculations and types of moves, which allowed the number of possible moves in each round to be limited to about 107. (Traditionally, AI calculates all possible scenarios before the move, up to the last move). Such calculations took DeepStack only five seconds.

Such systems can be effective in practical applications, since asymmetric distribution of information is quite common in the real world, for example, when it comes to protecting strategic resources or important medical recommendations.
