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 ... >>

Mini air conditioner Sony Reon Pocket 5 09.05.2024

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, ... >>

Full HD TVs fail the test 30.08.2007

No Full HD TV can offer full HD resolution when displaying moving objects, according to the latest research from Home Theater magazine.

Of the nineteen Full HD TVs tested, ranging from 40 to 67 inches, only twelve models were able to display 1080p on a still image. The resolution of other models ranged from 850 to 1050 vertical pixels. When displaying moving objects, the situation turned out to be more deplorable. The actual resolution ranged from 500 to 880 vertical pixels.

Vizio GV47FHDTV LCD TV was recognized as an obvious outsider of the tests. In the static test, it brought out 400 horizontal lines and 360 - while driving, with 1080 declared. The worst results when displaying dynamic scenes, following the Vizio GV47FHDTV, were shown by the Sony KDL40W3000 LCD TV, which brought out only 500 horizontal lines. The real resolution of the Sony KDL46W3000, Sharp LC37D62U and Samsung LNT4661F LCD TVs also turned out to be less than 600 lines, again when displaying moving objects. What is characteristic - the best indicators belong to plasma TVs.

The leaders of the experiment were 50-inch Panasonic TH-50PZ700 and TH-50PZ750 plasmas, capable of displaying 1080 lines in statics and 880 lines in motion. Plasma TVs from Samsung and projection TVs from JVC also distinguished themselves. The Panasonic TH-50PZ700 handled the Full HD display better than the others. Models of the following brands took part in the study: Mitsubishi, JVC, LG, Panasonic, Samsung, Sharp, Sony and Vizio.

To determine the real resolution, the FPD Benchmark software developed by the Consumer Electronics Manufacturers Association was used. The software outputted a series of monochrome grids consisting of vertical and horizontal lines.

Last year, the focus was on the quality of HD broadcast reception. It turned out that less than half of HDTVs are able to correctly receive an interlaced high-definition signal and convert it to a progressive signal. This year the results were much better. Of the 74 flat-panel TV models tested, about 65% completed the task.
