Milk from water. The Secret of Focus

Focus Description:

You have two glasses half filled with water on the table. And with the words: “And now I will turn the water into milk,” make several magical passes with your hands over the glasses and pour both liquids together - the liquid will become white, like milk.

Focus secret:

Of course, there was no water in the glasses. Place five measuring spoons of calcium chloride in one glass, and the same amount of washing soda in another and fill with water to about a third of the glass. The solutions will look no different from water. Then when you merge them together, a chemical reaction occurs - a substance is formed that looks like milk.

Advice: the sediment quickly sinks to the bottom, and everyone will see that this is not milk at all, so without wasting time, quickly remove the pseudo-milk from the table and move on to another focus, or add a solution of hydrochloric acid to it in excess - and “milk”, instantly boiling, will become "water" again.

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 ... >>

Fast and flexible electrical circuits for wearable electronics 04.06.2016

Engineers from the University of Wisconsin-Madison (USA) have created an electrical circuit with the maximum flexibility and speed to date, which is necessary for the development of wearable electronics and the Internet of things.

The prototype consists of two very thin intertwining S-shaped conductive lines. This shape allows stretching without loss of electrical conductive properties. At the same time, the circuit is protected from external interference. At the moment, the circuit can operate in the radio frequency range up to 40 GHz.

In this case, unlike other flexible transmission lines, which are up to 0,64 mm wide, the new development can have a width of only 0,025 mm. Such dimensions make it possible to effectively use it, in particular, in the creation of epidermal electronic systems - in devices that read indicators from the skin surface.
