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.

Vodka from water and air 08.11.2019

New York Air Co. developed a recipe for vodka, consisting only of water and air. No grains, no yeast, just electricity.

The company turns carbon from air into pure ethanol by electrically splitting water into hydrogen and oxygen. The carbon, oxygen and hydrogen atoms then recombine to form "environmentally friendly" ethanol.

"The process is similar to photosynthesis, but more efficient," explains Air Co. CTO. Stafford Sheehan.

The technology of the Americans simplifies the production of vodka and at the same time cleans the air, taking carbon from the external environment. The company calculated that one bottle of vodka purifies the air like seven large trees. In other words, each bottle removes half a kilo of carbon dioxide, writes CNBC.

Air Co.'s air recycling machine takes up little space and is powered by solar energy. The only by-product in production is oxygen. Unlike other vodka companies, Air Co. no need for giant fields for grain.

The only negative for consumers may be the price - $ 65 per bottle. At first, it will be sold only in some bars and restaurants in New York, and in 2020 it will reach retailers. CNBC representatives tried Air Co. - they say, vodka is like vodka. The taste is indistinguishable from the usual.

However, on one Air Co. will not stop. The company is going to produce perfumes and cleaning products for the home, adding to them ethanol produced using electricity.
