Why is it not enough to kill a moth butterfly to save woolen clothes?

If you kill a moth butterfly flying around the apartment, this does not mean that woolen things are saved from being eaten. Because butterflies only lay their eggs in these things. They are eaten by caterpillars that have already hatched from eggs, which must be fought with special anti-moth agents.

Which languages do not distinguish between blue and green?

Initially, in Japanese there was no distinction between blue and green colors, and one word was used to designate them - "aoi". Distinguishing blue and green in educational textbooks began only in the middle of the 20th century, but even today the word "aoi" can denote the color of vegetation. And in many other Asian languages, even if there are separate words for these colors, natural objects, such as leaves, are indicated in blue, and only man-made green objects in green.

Energy from space for Starship 08.05.2024

Producing solar energy in space is becoming more feasible with the advent of new technologies and the development of space programs. The head of the startup Virtus Solis shared his vision of using SpaceX's Starship to create orbital power plants capable of powering the Earth. Startup Virtus Solis has unveiled an ambitious project to create orbital power plants using SpaceX's Starship. This idea could significantly change the field of solar energy production, making it more accessible and cheaper. The core of the startup's plan is to reduce the cost of launching satellites into space using Starship. This technological breakthrough is expected to make solar energy production in space more competitive with traditional energy sources. Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

Virtual keyboard on beams of light 22.04.2002

CeBIT presents a full-sized virtual keyboard for mobile devices, developed by the Israeli company Developer VKB.

The image of the keys is projected directly onto the surface of the table. Rays of light register hand movements. Information is transmitted to the device to which the "keyboard" is connected. The same projector can replace a mouse.

The creators suggest that the new device will find demand among users of compact devices that do not have a keyboard. It can be connected to pocket and tablet computers, mobile phones, and possibly even laptops.
