Solar compass

02.12.2023

Based on scientific data on the orientation system of insects, scientists from the University of Edinburgh have presented an innovative solar compass that can determine direction by focusing on the light of the Sun, even in dense clouds. Equipped with eight light sensors, the device measures the polarization of sunlight, recreating the navigation principles used by insects such as ants and bees.

Inspired by the natural navigation of insects, the solar compass provides a promising solution for reliable and accurate orientation in various environments, which could lead to a revolution in navigation technology.

The ideal compass for precise navigation should be reliable, accurate and independent of external factors. Modern technologies such as GPS have their limitations, especially over short distances, and require open skies. Traditional magnetic compasses are susceptible to electromagnetic interference, making them unsuitable for use in robots and drones.

Created in Edinburgh, the solar compass is an integrated device with eight light sensors that can measure the intensity of sunlight and its polarization. These parameters allow it to work even in cloudy conditions where other technologies may fail.

The first tests of the compass were carried out successfully, although its size is still too large for robots with a diameter of 15 centimeters. In future studies, the scientists plan to reduce the size of the device and test its effectiveness under conditions of night-time illumination from the Moon.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

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, ... >>

The traffic light will help the car 30.03.2014

The Audi Group, part of the German automaker Volkswagen, has developed an intelligent system that informs motorists about the work of traffic lights in the city. An electronic assistant called Audi Traffic Light Recognition is able to reduce the number of traffic jams, as well as reduce fuel consumption and emissions of harmful substances into the atmosphere.

According to the idea of the Ingolstadt developers, data on traffic signals on the way of the car will be displayed on the dashboard. There, the driver will also be able to see a hint with the optimal speed, which must be selected in order to pass the nearest intersection on a green light. To do this, car electronics will be connected to the city's traffic light control center via the Internet.

If the vehicle stops at a red light, the driver will see a countdown timer in front of him, showing the time until the green light turns on. At the same time, the technology will be able to work in tandem with the Start / Stop system, which turns off the engine during downtime and starts it again when the driver presses the gas pedal. In the case of Audi Traffic Light Recognition, the engine will start five seconds before the traffic light turns on.

Audi claims that by teaching cars to interact with traffic lights, it will be possible to reduce the level of harmful emissions by 15%. The introduction of the development in the territory of Germany alone will save about 900 million liters of fuel. In addition, the project will help optimize car traffic by reducing the number of traffic congestion.

The traffic light recognition system is being tested in several cities, including Verona, Berlin and Las Vegas. According to the automaker, the new product is ready for mass production and can be installed in all new Audi models, but first it is necessary to obtain permission from the authorities to implement the project.
