PENTAX Stops Production of Compact and SLR Analog Cameras

15.06.2004

According to Pentax, despite the worldwide recognition and uniqueness of PENTAX film cameras, the corporation is ceasing production of both compact and SLR analog cameras.

Of the entire line of film cameras, PENTAX will continue to produce exclusively professional medium format photographic equipment. Thus, Pentax Corporation became the first company from the so-called "big five" photo brands, which will fully concentrate on the most relevant line of digital cameras of various classes today (including professional and amateur digital "reflex cameras"), as well as the production of "hybrid photo-video cameras.

However, there is still a chance for consumers to purchase film cameras such as the Espio 24EW (a high-end compact camera with a 24-105mm ultra-wide-angle zoom lens) or the Espio 140V (one of the best value for money cameras in its class). And keen photography enthusiasts might want to consider buying film SLRs (such as the *ist model, which has become a hit with high-end amateur DSLRs) and lenses, which will be on sale for about another six months.

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, ... >>

Eternal flash memory 11.12.2012

The new technology allows to increase the maximum number of rewrite cycles in flash memory from 10 thousand to 100 million. Scientists from the company Macronix, located in Taiwan's city of Hsinchu, have developed a technology that can save flash memory from the effect of aging.

The aging effect is one of the shortcomings of flash memory, which, along with other factors - primarily cost - prevents its mass distribution. The fact is that the constant exposure to high voltage cells wears them out, and over time they lose the ability to take on a clear logical state.

Modern flash memory loses its ability to reliably store information after 10 rewrite cycles. In the case of a USB stick, which is also based on flash memory, this does not matter due to the generally short lifespan. However, for SSD drives that laptops are equipped with, this is important, since the life of a computer can be several years. This indicator is even more important for corporate data storage systems with a high load.

With the goal of improving the viability of flash memory, scientists turned their attention to a type of memory based on the phase state of matter. In phase memory, a cell changes its conductivity when heated. The researchers found that similar heating of a cell in flash memory has a recovery effect.

Following this discovery, the scientists modified the conventional flash memory chip by adding tiny heaters for groups of cells. By heating the cells to 800°C for a few milliseconds, they were able to extend their life cycle. According to Macronix spokesman Hang-Ting Lue, under laboratory conditions, they were able to extend the life of flash memory up to 100 million write cycles. But the company claims that the theoretical limit could be as high as 1 billion cycles. Researchers have not yet had the opportunity to understand this limit, as testing will take several months.
