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, ... >>

mystical experience 05.03.2016

The mystical experience can be described in different ways: someone feels the presence of some higher powers, someone discovers higher knowledge, someone's perception changes, etc. For someone, "mysticism" happens in a hospital, in an intensive care unit , someone is visited by strange visions when immersed in a meditative trance. During a mystical experience, a person understands that something inexplicable has happened to him, beyond the limits of understanding.

Neurobiological hypotheses that explain mystical experience are usually divided into two parts: some say that there is a certain generator of the transcendent in the brain - a special zone that, when activated, gives us some strange experiences, while others argue that the whole thing is not so much in a particular zone, how much is that the braking system does not work very well in the brain.

The work of the nervous system as a whole looks like an alternation of waves of excitation and inhibition. In order to bend the arm, you need to excite a group of flexor muscles and slow down a group of extensor muscles, and in order to regulate muscle strength, you need to extinguish the excitation in those neurons that induce the muscle to contract in time. The same thing happens in emotions and in thinking. In order to suppress a neuron that generates an excitatory signal, another neuron must turn on - an inhibitory or inhibitory neuron, which, having activated itself, will suppress the activity of the excitatory neuron.

In other words, inhibition is not just "turning off the brain", as it might seem. When braking, the brain works as it did, just now other nerve pathways are activated in it. And, if these very paths suddenly break down, if their activity falls, then the nervous system is threatened with overexcitation, which can manifest itself in improper muscle work, and in emotional instability, and in general in behavior.

Jordan Grafman of Northwestern University, along with colleagues from other medical centers in the United States and New Zealand, analyzed the brain state of nearly XNUMX Vietnam War veterans. All of them underwent psychological tests before they were sent to the places of hostilities, and after returning from there.

Some of the soldiers received brain injuries, and many of them suddenly began to see members of their family, who were not actually there, or even hear words coming from, as they said, from some higher being. Mystical experience was evaluated on a special scale (it turns out that there is one). The results of psychological tests were supported by the results of computed tomography of the brain.

The strongest transcendental experiences occurred in those who had damage to the frontal and temporal lobes of the brain, and this was especially true of the dorsolateral prefrontal cortex - if the injury affected it, then in most cases one could expect mystical revelations.

The dorsolateral prefrontal cortex generates the inhibitory impulses discussed above; that is, with a certain degree of certainty, it can be argued that it is the failure of the "brake systems" of the brain that opens the "doors of perception" to us. The frontal lobes are responsible for a lot of everything, from muscle control to memory and speech, so they can very well create something complex and mystical - of course, if they are not interfered with.

According to neuroscientists, the "brake pads" (that is, the dorsolateral prefrontal cortex) help build a complex explanation for the observed phenomena, the causes of which are not obvious and which are most easily attributed to the intervention of supernatural forces.
