Blinking of the magician and his audience 19.05.2024

Magic and illusions have always captured the attention of the public, but what happens behind the scenes of the magician and in the brains of his audience? Scientists from the UK decided to solve this mystery by conducting a new study involving ten illusionists of varying experience. Illusionists, some of whom had been practicing magic for more than half a century, others for only six months, were invited to demonstrate the same trick - the popular coin trick. Recordings of their performances during training and on stage showed that each of them began to blink significantly more often at the moment of performing the trick. The study's findings indicate that magicians' blink rate may be related to unconscious aspects of their performance. At the same time, as scientists have found, spectators also begin to blink more often, following the movements of the illusionist. This observation supports the idea that magicians may be catalysts for blinking in audiences. Additional research has shown that magicians blink more often during ... >>

Ultrasonic coffee machine 19.05.2024

Iced coffee has become an integral part of coffee culture in recent years. Therefore, engineers from the University of New South Wales decided to improve its preparation. They have developed an ultrasonic coffee machine that reduces the cold brew time for ground coffee beans from 12-24 hours to significantly less time. Iced coffee, or "Cold brew", is popular due to its smoothness, low acidity and low bitterness. It is prepared by steeping ground coffee in cold water for a long time. Unlike traditional hot brewing, which often imparts bitterness to coffee, cold brewing extracts more delicate and complex flavors from the coffee beans. The innovative system, presented by a team of engineers, introduces ultrasonic technology into the coffee preparation process. The system uses ultrasonic waves to speed up the process of extracting oils, flavor and aroma from ground coffee. This allows you to significantly reduce the time ... >>

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.

Meta-laser that produces highly swirling light 10.05.2020

Scientists from Harvard University (USA), CSIR organization (South Africa), with the participation of colleagues from Singapore, Belgium and Italy, have developed and demonstrated the operation of the first meta-laser of its kind, which produces the so-called super-chiral light, the light with the largest present day value of angular momentum. The light of such a laser provides the highest level of interaction between matter and this light, and it can be used as an optical "wrench" or to encode large amounts of information transmitted through optical communication channels.

Judging by the presence of the prefix "meta" in the name of the new laser, its key component is the metasurface, which affects the light and changes its parameters every time this light passes through it. The metasurface was calculated and fabricated by Harvard scientists, it is a material whose surface is covered with many small (nanometer-sized) columns, the height, width and distance between which have been carefully calculated to obtain the desired effect. And when light passes through such a surface, it turns at a certain angle each time.

In addition to the fact that the created metasurface itself has a high phase gradient, it is capable of transmitting a sufficiently powerful light flux through itself without any disruption, which significantly pushes the boundaries of the use of such lasers.

As a result of all the measures and tricks described above, the new laser is capable of producing light with 100 times more angular momentum and 10 times more power than any other similar lasers created until recently. At the same time, the new laser provides the possibility of complete control over the angular momentum (AM), rotation (polarization) and orbital angular momentum (OAM) of the light beam emerging from it. And all that is required for this is just a change in a few parameters of the light used to pump the laser.
