Increasing popularity of cell phones with cameras

20.09.2003

In the first half of this year, sales of mobile phones with built-in cameras surpassed sales of conventional digital cameras by a ratio of 25 million to 20 million, according to CNN.

I must say, this is a rather interesting trend, although quite expected. After all, mobile phones equipped with digital cameras and applications for them became one of the new technological trends of 2003. According to experts, sales of such phones for the whole year will reach 65 million units, or 13% of the total number of mobile phones.

The leading position in this market segment is occupied by handsets of Japanese manufacturers - NEC and Panasonic. They are followed by a well-known Finnish manufacturer of mobile phones - Nokia.

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 ... >>

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, ... >>

martian cities 16.09.2013

The huge Martian crater Aram Chaos was formed as a result of the catastrophic melting of ice and the outflow of water from an ice-bound lake.

A new study by scientists from the University of Utrecht and Jacobs University Bremen has shown that the 280 km diameter and 4 km deep Aram Chaos crater's enigmatic relief was formed by the outflow of hundreds of thousands of cubic kilometers of water. In just about 1 month, liquid water, with a volume 4 times the volume of the waters of Lake Baikal, cut through a large valley 10 km wide and 2 km deep in the Martian surface. A heap of rocks remains in the Aram Chaos crater itself, but scientists believe that large reserves of water ice could still remain in the former giant water reservoir, which in the future can be used to supply the Martian settlement.

The Aram Chaos crater has long been of interest to scientists. The ancient impact crater has an unusually uneven bottom, "littered" with large pieces of rocks. Real chaos is going on inside and outside the crater: rugged terrain, which seems to have been plowed with giant plows and sown with boulders. Until now, scientists did not understand what exactly is causing this picture, but the results of the latest study, based on satellite observations and computer simulations, show that there was a real "water explosion" on Mars.

About 3,5 billion years ago, the then still intact impact crater Aram Chaos was filled with water ice, covered with a 2-km layer of rocks. A layer of ice, covered with a blanket of sand and stones, has been melting for millions of years under the influence of heat generated by the bowels of the planet. When there was too much water, the walls of the crater could not stand it and collapsed. The released water, hundreds of thousands of cubic kilometers, forever changed the terrain.

The most intriguing suggestion is that unmelted ice may still be present in various Martian craters, including the Aram Chaos crater. These vaults of ice are evidence that the once-aquatic planet has rapidly degenerated into a frozen cold world. On the other hand, craters with large reserves of ice can be an excellent place for the construction of future Martian settlements.
