Electric train with a speed of 369 km/h

11.05.2006

The new Spanish electric train set a European speed record on rails - 369 kilometers per hour. The special shape of the locomotive hood, designed for the least air resistance when overcoming tunnels, gave the Spaniards a reason to call the train "El Pato" - a duck.

So far, the country's railway network is not adapted to such speeds, so for about a year the speed of trains will not exceed 200 kilometers per hour. Later, the speed of regular traffic will increase to 330 kilometers per hour, and it will be possible to get to any major city in Spain from Madrid in a maximum of four hours.

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, ... >>

HighPoint Rocket 750 HBA card connects up to 40 SATA 3.0 HD 15.04.2013

The Rocket 750 host bus adapter (HBA, Host Bus Adapter) will soon be available from HighPoint, which allows you to connect up to 40 hard drives with a SATA 6 Gb / s interface to your computer. The manufacturer claims that this is the first HBA device in the industry to support so many SATA 3.0 drives.

The novelty is aimed at applications that require work with huge amounts of data. It can be used in data libraries, digital archives and when backing up large amounts of data. Rocket 750 eliminates the need to purchase expensive SAS extenders, which helps reduce costs, the developers say.

The adapter board for connecting to a PC uses the PCI Express 2.0 x8 interface. Its bandwidth is 4 GB / s. In fact, this is the bottleneck of the system (maximum load is 40 x 6 / 8 = 30 GB / s), but in real applications this should be enough. Each of the ten ports allows you to connect up to four SATA drives with a capacity of up to 4 TB each using Mini SAS cables. Thus, the total capacity of the disk array reaches 160 TB. Intelligent Storage Health Manager software is available for monitoring system health.

In the US, the novelty will appear this month at a price of $739.
