Focus Description:

Clay volcano eruption.

Focus secret:

For the volcano model, prepare some plasticine or clay, a mixture of a teaspoon of soapy liquid and a few drops of food coloring, a tablespoon of baking soda and vinegar.

Divide the plasticine or clay into two parts: from one mold a flat base, from the other - a cone for the top of the volcano. Pinch the edges of both shapes and make sure the "volcano" is waterproof. Put it on a plate. Pour the colored soapy liquid into soda - you get "lava". Pour it into the volcano.

You have vinegar on hand. Now you can start demonstrating focus. Announce to the audience: "This is Mount Etna - the most terrible volcano after old Etna. I can cause an eruption at will." Then pour some vinegar into the mouth of the volcano.

Viewers will be mesmerized when they see his "eruption". Exclaim: "Save yourself, who can!" Beautiful fiery lava will begin to pour out onto the table.

The speech of sperm whales is similar to that of humans 18.05.2024

In the world of the ocean, where the mysterious and unknown coexists with the studied, sperm whales, with their huge brains, are of particular interest to science. Researchers, working with a huge array of audio recordings collected during the Dominica Sperm Whale Project (DSWP) - more than 8000 recordings, seek to unravel the secrets of their communication and understand the structure and complexity of the language of these mysterious creatures. By studying in detail the recordings of 60 sperm whales in the eastern Caribbean, scientists have revealed surprising features of their communication, revealing the complexity of their language. "Our observations indicate that these whales have a highly developed combinatorial communication system, including rubato and ornaments, which indicates their ability to quickly adapt and vary during communication. Despite significant differences in evolution, sperm whales have elements in their communication that are characteristic of human communication," says Shane Gero, a biologist at Carleton University and director of the CETI project.

Electron spin for quantum information transfer 18.05.2024

The transfer of quantum information remains one of the key tasks of modern science. Recent advances in the use of electron spin to expand the capabilities of information transfer in quantum systems have become very important. Researchers at Lawrence Berkeley National Laboratory are pushing the frontiers of quantum information science by experimenting with the possibilities of electron spin. Electron spin, a natural quantum bit, is a potentially powerful means for storing and transmitting information in quantum systems. Magnon wave packets, collective excitations of electron spin, have revealed their potential to transmit quantum information over significant distances. The work of Berkeley Lab researchers has revolutionized the way such excitations propagate in antiferromagnets, opening up new prospects for quantum technologies. Using pairs of laser pulses, scientists disrupted antiferromagnetic order in one place and simultaneously studied it in another, creating ... >>

Sound-absorbing silk 17.05.2024

In a world where noise is becoming increasingly intrusive, the emergence of innovative materials that can reduce its impact is of great interest. MIT researchers have unveiled a new sound-absorbing silk fabric that promises to revolutionize quiet spaces. The Massachusetts Institute of Technology (MIT) has made significant breakthroughs in the field of sound absorption. Researchers have developed a special silk fabric that can effectively absorb sound and create cozy, quiet environments. The fabric, thinner than a human hair, contains a unique vibrating fiber that is activated when voltage is applied to it. This feature allows the fabric to be used to suppress sound waves in two different ways. The first method uses fabric vibrations to generate sound waves that cover and cancel out unwanted noise, similar to noise-canceling headphones. This p ... >>

Smart people think slower 26.05.2023

Do smart people think faster? According to the results of a study by a group of scientists from Germany and Spain, not always, and in the case of solving complex problems, some advantages go to people with a less developed intellect.

The adult human brain consists of billions of neurons connected by numerous connections. These complex and sometimes intricate networks are both the key to the amazing possibilities of the brain and the main difficulties in the way of studying it.

Since it is difficult to work with the brain of a living person, researchers are increasingly turning to computer simulations using digital brain scans, such as magnetic resonance imaging (MRI), as well as mathematical models based on theoretical knowledge about biological processes.

At first, this allows you to build a "general" model of the human brain, but then scientists refine it using data from individual people and create "personalized" brain models.

To study how general intelligence affects the speed of solving various problems, an international team of researchers created 650 "personalized" brain models of participants in the Human Connectome Project. This made it possible to effectively reproduce the activity of each studied brain, analyzing the intellectual characteristics and reaction time of a particular person when solving various problems.

Subsequently, the indicators of these models were compared with the indicators of the participants themselves, who were offered to solve a series of tasks that gradually become more difficult to select gradually more complex elements in the "puzzles".

The researchers found that participants with higher IQ scores were faster on simple tasks, but took longer to complete complex ones. At the same time, parts of their brain were better synchronized with each other, constantly exchanging information and slowing down the final decision.

On the other hand, the brains of people with low IQs literally jumped to conclusions when making difficult decisions, rather than waiting for higher brain areas to complete processing steps, which is why such people made mistakes more often.

According to the findings of the researchers, in general, the indicators of "personalized" models coincided with those of the brain of living people, which proves the effectiveness of computer simulation of the human brain. In the future, such methods can be applied in medicine: for example, using computer simulation, a doctor will be able to evaluate which drugs will be most effective in treating a particular patient and cause the least amount of side effects.
