electromagnetic pistol

08.12.2021

China's Wuhan Naval Engineering University has developed a prototype weapon that contains three coils that generate an electromagnetic field. In the development, scientists used artificial intelligence methods.

Engineers have created a Gauss pistol of record power. A pistol, or Gauss cannon, is one of the varieties of an electromagnetic mass accelerator. Inside the barrel there are conductive coils to which a current pulse is applied. This creates an electromagnetic field that accelerates the magnetized projectile - it shoots out of the barrel.

The advantage of such a gun is silent shooting with low recoil. The Chinese prototype has a barrel length of 12 centimeters, and its muzzle energy reaches 150 joules, which is comparable to small-caliber firearms.

The effectiveness of weapons was improved with the help of a neural network.

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, ... >>

Ultraviolet for myopia 12.12.2016

Scientists from JAMA Ophthalmology compared the medical history of more than three thousand people living in various European countries, from Norway to Greece. All of them were on average 65 years old, and several hundred of them suffered from myopia.

The researchers asked everyone about their diet, income level, past illnesses and a host of other things - among other things, the respondents were asked to indicate how much time per day (more precisely, from 9 am to 5 pm) they spent outside the home starting at the age of 14. At the same time, their blood was taken to analyze the level of vitamin D (which, as we know, is synthesized in skin cells under the influence of ultraviolet radiation).

Knowing, at least approximately, how much time a person spends outdoors, and knowing in which geographical area he lives, it is possible to calculate the amount of ultraviolet radiation that he received on average every day throughout his life.

It turned out that those who received large doses of ultraviolet radiation in their youth were less likely to have myopia - by the age of 65 they saw better than others who had not received UV radiation at one time. It would be logical to assume that the whole point is in that very vitamin D, especially since, according to some sources, the higher its level, the lower the likelihood of myopia. However, this time, no such pattern could be found: the level of vitamin D did not correspond in any way to whether the person’s eyes were healthy or not.

It can be assumed that UV rays act differently; some of the earlier research suggests that ultraviolet light specifically activates eye cells and regulates the growth of the eye so that it becomes resistant to myopia. However, no matter how tempting the "ultraviolet prophylaxis" of myopia may look, all these dependencies and regularities need to be repeatedly rechecked.

One cannot speak of a causal relationship between one and the other, all we know is that the two parameters - the amount of ultraviolet light and the likelihood of myopia - are somehow related to each other. It is also worth noting that the authors of the work judged by the dose of ultraviolet radiation, based on the memories of the study participants, how much time they spent in the sun forty years ago, and such data still cannot be called accurate enough.
