Yongnuo YN455 - Android mirrorless camera

16.07.2021

The Chinese company Yongnuo introduced a new mirrorless camera YN455, the main distinguishing feature of which was the use of the Android operating system. The novelty received a 20-megapixel Micro Four Thirds sensor and support for interchangeable lenses.

The camera can shoot videos with a resolution of 4K 3840 x 2160 pixels at 30 frames per second. The novelty is based on Qualcomm's unnamed eight-core Snapdragon processor, clocked at up to 2,2 GHz. It comes with 6GB of RAM and 64GB of permanent storage, expandable via microSD card up to 256GB.

To control the camera and view the shots taken, a 5-inch tilting touch screen is provided. The battery is removable, with a capacity of 4400 mAh. There are two USB Type-C ports, a 3,5mm combo audio jack, Wi-Fi, Bluetooth and GPS, and a 4G modem.

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, ... >>

Science requires sacrifice 02.04.2003

Scientists are exposed to more stress at work than employees of commercial companies. This conclusion was reached by the authors of a psychological study conducted on more than 900 teachers at the Massachusetts Institute of Technology (USA).

More than 60 percent of those surveyed say they feel emotionally and physically drained at the end of the working day, and 78 percent complain that no matter how hard they try, they don't get everything done in a day. For comparison: only half of the surveyed employees of various firms noted the same fatigue from work.

Two-thirds of MIT employees are dissatisfied with the hectic pace of their work and the intense stress they are exposed to. Two-thirds work 60-hour weeks or more, while in 1989 less than half had such busy work schedules.

More than 50 percent of respondents say that this stress has a bad effect on family life and relationships in the workforce. Women and those who do not have a permanent position, but work temporarily, under an employment contract that will not necessarily be extended, feel especially great stress.
