Focus Description:

At home, you can make a real volcano that will spew lava!

Focus secret:

To arrange a volcano, quite safe and, nevertheless, very effective, you will need: a plate, plasticine, baking soda (sodium bicarbonate), table vinegar, acetic acid (you can use a 3-9% solution of acetic acid), dye (you can take red food coloring or beetroot juice), any dishwashing liquid.

Divide the plasticine into two parts and roll one of them into a flat pancake - the base of the "volcano", and from the second blind a hollow cone with a hole at the top (slopes of the "volcano"). Having pinched both parts along the edges, it is necessary to pour water inside and make sure that the "volcano" does not let it through from below. The volume of the internal cavity of the "volcano" should not be very large (preferably 100-200 ml, this is equal to the volume of a teacup or ordinary glass).

Place the plate with the "volcano" on the tray. To "charge the volcano with lava", prepare a mixture of dishwashing liquid (1 tablespoon), dry baking soda (1 tablespoon) and dye (a few drops are enough). Pour this mixture into the "volcano", and then add vinegar (about 40-50 ml, or a quarter of a cup) there. A violent reaction begins with the release of carbon dioxide. Brightly colored foam is shown from the "vent" of the volcano.

After the experience, do not forget to thoroughly wash the plate!

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 ... >>

Light leads to the quantum world and the acceleration of supercurrents 22.05.2020

Scientists have already been able to use light waves to accelerate supercurrents and gain access to the unique properties of the quantum world, including forbidden light emissions. The scientific world believes that sometime in the future these unique technologies can be applied to high-speed quantum computers and other, more advanced technologies.

In supercurrents, scientists were able to observe an incredible phenomenon. An electric charge can move through materials without resistance and at ultra-low temperatures. This is forbidden by the usual laws of physics, such a phenomenon breaks the symmetry.

However, according to Jigang Wang, professor of physics and astronomy at the University of Iowa, it exists. For the first time, researchers have been able to use light pulses at terahertz frequencies to accelerate electron pairs known as Cooper pairs. They were passed inside the overcurrents.

At the same time, trillions of pulses could pass in one second. Scientists have determined the path that is created by pairs of electrons that were in acceleration. This method made it possible to detect light with twice the frequency of the incoming energy, which is used to accelerate the electrons.

But earlier it was always considered that terahertz terahertz radiation of the second harmonic in superconductors is impossible. And in fact it is not. The researchers used terahertz laser flashes as a piece of control to accelerate supercurrents and access new and potentially useful quantum states of matter. Forbidden light was able to give scientists access to an exotic class of quantum phenomena - energy and particles on the small scale of atoms.

It was possible to achieve such results thanks to the use of a special tool called quantum terahertz spectroscopy. Its peculiarity lies in the ability to visualize and direct electrons. The scientists argue that access to this and other quantum phenomena could help spur major innovation.
