Focus Description:

Place a liter plastic bottle full of water on the table. Then toss a few mothballs or camphor balls (used to protect clothing from moths) into the bottle and they mysteriously begin to float up and down in the water column. This can go on almost indefinitely and looks very entertaining.

Focus secret:

The secret of the trick is that "water" is not really water at all. This is a chemical preparation, which only you yourself will know about.

You need to take four teaspoons of baking soda and four teaspoons of citric acid crystals and mix them together in a large mug.

Pour this mixture with a liter of water; within a minute or so it will foam and sizzle. When the foam settles, pour the "water" into a liter bottle. Now all you have to do is toss balls into this "water" bottle and watch the effect.

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 ... >>

Xiaomi USB-C Multi-Function Adapter 31.05.2017

Xiaomi has introduced a USB-C Multi-Function adapter.

The novelty is useful for owners of new MacBooks that do not have a standard connector. The accessory can transmit data to display the illustration on the screen or even a TV in 4K Ultra HD resolution.

The cost of the device will be approximately $ 21. It has 4 USB 3.0 ports that operate at the highest possible speed.

All cables in the Xiaomi phone, tablet and laptop adapter are made of tinned copper, which ensures the stability and high bandwidth of signal transmission at high speed.
