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.

Digital apocalypse 18.12.2021

Experts warn that in a few years we will face a digital apocalypse associated with an exponential increase in the amount of data that, until recently, no one could have imagined even in the wildest forecasts. In this regard, scientists call to recognize digital content as the fifth state of matter, along with gas, liquid, plasma and solid. They argue that at some point humanity will accumulate so much digital data that the number of bits that make up this data will approach the number of atoms that make up the entire Earth (10 to the 50th power).

To store and process this amount of information, humanity will require much more energy, in contrast to how much it currently produces. Hence the call of scientists to stop considering digital content solely as a virtual sequence of ones and zeros, and treat it as a specific physical quantity, that is, matter.

It is estimated that humanity generates data every day that requires 2,5 trillion bytes (eight times more than a bit) to store. To understand how much data will have to be stored on a certain area of ​​physical media, the size of a bit must be equivalent to the size of an atom. If we assume that the amount of data generated by mankind will increase by 50% every subsequent year, then the number of bits required to store this amount of information will be equal to the number of Earth's atoms in 150 years.

Following this logic of reasoning, half the mass of the Earth should be used to store this amount of information. It sounds incredible, but scientists have given calculations that confirm this. Of course, technological progress and new scientific discoveries may lead to the fact that the situation will not be so dramatic. However, we are rapidly approaching a point where such warnings should not be ignored.

Scientists also suggest that our lives in the future will be almost 100% virtualized. This means that it will be controlled by computer codes and bits. This may seem exciting to many, but in fact, such a prospect is frightening, and makes you think about the biblical question - Quo Vadis ...
