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.

Spin transistors will increase the speed of computers a million times 20.07.2012

A group of American researchers from Northwestern University has developed a family of completely new logic networks that use magnetic semiconductor devices instead of conventional transistors. Scientists claim that this could increase the power of future computers by a million times. In other words, we are talking about spintronics, which, instead of the charge of an electron, uses its other characteristic - spin. Spintronics has long been predicted to replace electronics, but logical spin networks have not yet been developed.

As you know, Moore's empirical law states that approximately every two years the number of transistors in a microchip doubles. This rule has been working since the fifties of the last century, but now it has begun to fail, since transistors have almost exhausted their possibilities in terms of further miniaturization. One of the main obstacles here is the heat dissipation of transistors - the more of them in the microchip, the more it heats up. Therefore, the use of today's transistors in the computers of the future is not possible.

In 2010, the same group created and then patented the so-called magnetoresistive bipolar spin transistors, and now they have learned how to make new logical networks out of them.

“We have developed a device based on logic networks capable of performing all the necessary operations of Boolean logic,” says Professor Walter Murphy, one of the authors of the development. “Our spintronic logic is able to successfully perform all the operations that are required today from circuits with conventional transistors, but with fewer elements and much greater performance, he says that the "spin logic networks" they created have the potential to lead to computers that are a million times more efficient than those currently on the market. this idea will take them about ten years.
