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, ... >>

Adult intelligence interferes with learning a foreign language 29.07.2014

For a long time, linguists have noticed that complex grammar is easier for children, as well as numerous exceptions to the rules in foreign languages.

Adults learn grammar harder because all the available mental resources of the prefrontal cortex of the brain are involved in learning a foreign language. It's possible that this part of the brain is silencing other, more intuitive learning mechanisms, says Amy Finn of the Institute for Brain Research at the Massachusetts Institute of Technology.

Amy Finn came up with nine two-syllable words in a fictitious language (a famous example of this kind is "gloss kuzdra"), after which she broke them into three "grammatical" categories.

Participants in the experiment could hear these words for about 10 minutes. One group was asked not to analyze what they heard, but also not to be distracted at all, so that their attention was not concentrated on the words. The second group, while the recording was playing, was asked to draw a picture or solve a crossword puzzle. The third group was given the task to determine all the words that the subjects could hear.

The entry included combinations of three words (from each category). As scientists know, even children and monkeys can distinguish individual words in a speech stream.

All participants in the experiment with this task coped equally well (and the group of "diligent" even better). In the same way, the passage of the second task was organized, during which the subjects had to distinguish the correct sequences of words (which they had previously heard in the recording) from incorrect ones.

The last test was for understanding grammar (morphology). Participants in the experiment were shown three words. The subjects had not met one of them before, but grammatically it could be easily entered into one of the three available categories. As a result, when answering the question about the correctness or incorrectness of the location of the new word, the group of "diligent" made much more mistakes than those who listened to the recording inattentively.

The results of the experiment confirmed the hypothesis that two types of memory are used when teaching a foreign language. Explicit, or verbal, which stores facts and knowledge, helps to expand vocabulary, as well as memorize grammatical rules. As for implicit (procedural) memory, which directs a person's intuitive actions (i.e., those that he performs without thinking), it is responsible for the rapid use of complex grammar.

If you use the resources of verbal memory to learn a language, as adults usually do, then it will not allow you to speak freely: you can learn a lot of words and rules, but still not start speaking a foreign language fluently. In order to get rid of this problem, Amy Finn suggests that in the process of listening to someone else's speech, divert the prefrontal cortex to other mental exercises, or even turn it off through transcranial magnetic stimulation.
