Inspiration is born between sleep and wakefulness

18.12.2021

History knows many cases when inspiration came to great people in a dream, and these great ones sometimes even used special methods in order not to forget their sleepy insights. For example, Thomas Edison and Salvador Dali, thinking about some difficult creative task, lay down to take a nap, holding something heavy in their hands. When they started to fall asleep, the hand relaxed, the object fell to the floor and woke them up - and then it turned out that the solution to the creative problem was already in their head.

Employees of the Sorbonne University decided to test this method and invited one hundred and three people for the experiment, who were also supposed to doze off with a heavy object in their hand. Before falling asleep, they were given a mathematical problem: several number sequences had to be continued by one more number, and in order to get this number, two mathematical rules had to be applied to the sequence. However, the solution to the problem could be easier if you noticed that the required number is always the same as the second number in the sequence.

The participants in the experiment recorded the electrical activity of the brain to monitor how their brain falls asleep. We know that there is REM sleep, or REM sleep, with rapid eye movements, and non-REM sleep, or NREM sleep. But there are several stages in non-REM sleep, and one of them, called N1, looks like an intermediate state between sleep and wakefulness: brain waves are rebuilt into a sleepy state, but it seems to the person that he is not sleeping yet. After stage N1, other, deeper stages of non-REM sleep begin.

The first stage of sleep really awakened the creative powers of the brain. If a person solved the above problem without falling asleep, then a simpler solution came to mind in 30% of cases, but if he fell asleep and immediately woke up, then this solution came to mind already in 83% of cases. Stage N1 lasted at least 15 seconds, and it was important not to fall into a deeper sleep - otherwise the brain would forget what it had thought of.

Perhaps the "pre-sleep" stage can indeed be recommended to those who urgently need to awaken their creative forces. True, it would be nice if some kind of device appeared here that would wake you up a few seconds after you dozed off - after all, falling asleep with something heavy in your hand is not very convenient.

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, ... >>

Canon Zoemini Smartphone Micro Printer 12.08.2018

Canon has introduced a new device called Zoemini, which is the brand's smallest and lightest photo printer. The device has dimensions of 118x82x19 mm and weighs 160 g. The printer is designed to print pictures from smartphones and tablets. Zoemini works with gadgets running Android and iOS operating systems. The proprietary application provides the ability to add filters and frames.

Printing requires special paper with ZINK technology, the crystalline substance of which is colored when heated. The result is photographs 76x50 mm in size. Communication with the smartphone is carried out via Bluetooth 4.0. The built-in 500 mAh battery allows you to print up to 20 photos.

The price of the device, including 10 sheets of photo paper, is 140 euros.
