How did the 18th century chess computer work?

In 1770, the Hungarian Wolfgang von Kempelen designed a chess "computer" - an apparatus in the form of a chess table and a mechanical Turk that moved the pieces with his hands. The apparatus won most of the games, among the defeated were Napoleon and Benjamin Franklin. Many scientists puzzled over the principle of the "Turk", and only 50 years later they exposed the deception - a live operator of the machine was hiding under the table.

Artificial leather for touch emulation 15.04.2024

In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>

Petgugu Global cat litter 15.04.2024

Taking care of pets can often be a challenge, especially when it comes to keeping your home clean. A new interesting solution from the Petgugu Global startup has been presented, which will make life easier for cat owners and help them keep their home perfectly clean and tidy. Startup Petgugu Global has unveiled a unique cat toilet that can automatically flush feces, keeping your home clean and fresh. This innovative device is equipped with various smart sensors that monitor your pet's toilet activity and activate to automatically clean after use. The device connects to the sewer system and ensures efficient waste removal without the need for intervention from the owner. Additionally, the toilet has a large flushable storage capacity, making it ideal for multi-cat households. The Petgugu cat litter bowl is designed for use with water-soluble litters and offers a range of additional ... >>

The attractiveness of caring men 14.04.2024

The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>

Global warming is accelerating the largest current in the Southern Ocean 04.12.2021

Scientists in the US and China have used data collected by Project Argo drifting buoys to determine what is causing the acceleration of the Southern Hemisphere's largest current, the Antarctic Circumpolar Current. It turned out that the main contribution to this process is not made by the wind, as previously thought, but by climate warming associated with human activity.

The Antarctic Circumpolar Current (ACC) is a cold surface oceanic current in the Southern Ocean. Scientists from the University of California at San Diego, Woods Hole Oceanographic Institute, the Chinese Academy of Sciences and the University of California at Riverside used satellite measurements collected by Argo's global network of drifting buoys to determine why the ADC has accelerated in recent years.

“Both observations and models, we can conclude that ocean temperature change is causing a significant acceleration of the ADC in the last decade,” says co-author Jia-Rui Shi. “This acceleration of the ADC, especially in its subantarctic part, contributes to the exchange heat and carbon between ocean basins".

The ADC surrounds Antarctica and separates cold water in the south from warmer subtropical water in the north. This warmer part of the Southern Ocean absorbs much of the heat created by human activities. It is critical to understand the dynamics of the ADC, as it can affect climate across the entire hemisphere.

The ADC is mainly driven by the wind. As the climate warms, westerly winds intensify. However, the results of the study showed that these changes do not accelerate the current, but only cause whirlpools directed against the main flow of water. The change in velocity is associated with the temperature difference on both sides of the current. When this gradient increases, the flow speeds up.
