South Telescope

06.04.2006

The largest telescope in the southern hemisphere of the Earth has come into operation in South Africa. The diameter of its mirror is 11 meters.

It is impossible to cast such a solid mirror, so it was assembled from 91 hexagonal mirrors with a diameter of one meter, fitting one to the other with great accuracy. The telescope will make it possible to study stars and galaxies located at a distance of up to 150 light years and invisible from the Northern Hemisphere.

The sensitivity of the telescope is such that, theoretically, it could see a candle lit on 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 ... >>

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, ... >>

XNUMXD ultrasound 11.06.2007

German programmers offer a cheap way to obtain three-dimensional images using a conventional ultrasound device.

A lot of interesting things can be seen inside the human body with the help of ultrasound - from kidney stones to tumors. However, a conventional device builds a two-dimensional picture. And for the surgeon to plan the operation, it would be useful to look at the three-dimensional image of the same tumor.

Such devices appeared in the 90s, they are very expensive, more than 50 thousand euros, and only a rich clinic in a rich country can afford this equipment. Scientists from the Fraunhofer Institute for Biomedical Technology figured out how to do the same for just 400 euros.

“We have equipped a conventional ultrasonic device with inertial sensors that can accurately indicate the position and orientation of the emitter,” says project leader Dr. Urs Schneider. “They are usually not very sensitive, the position measurement error is up to ten degrees. However, using a special algorithm, it was possible to reduce it tenfold This will be especially useful in Eastern Europe: its residents will also benefit from the best diagnostic methods.The system, which consists of a small device and software for it, will be ready for sale by the end of the year, and then it will be easy to upgrade existing ultrasound devices so to build three-dimensional images with their help.
