What is the famous painting by Henri Matisse exhibited at the New York Museum of Modern Art in 1961?

The picture of the French artist Henri Matisse (1869-1954) called "Boat" was accidentally hung upside down at the said exhibition, and in this position it hung for 47 days. None of the 116 thousand museum visitors who passed by the painting noticed this.

How did duels originate?

As we see it, a duel is a predetermined duel, which is carried out according to certain rules between two persons armed with deadly weapons, to resolve disputes relating to issues of honor. By this definition, some famous duels between two individuals were not duels. For example, it is assumed that the Hectori Achilles fought each other, but this was not a duel. The fact is that in ancient times there was a custom called a judicial duel. It was a legalized form of duel, with the help of which legal issues were resolved rather than those related to personal dignity.

For example, in some cases, when war was possible, they armed a prisoner from a hostile tribe and put him up against one of their best warriors. The outcome of this duel was considered an omen, since in those days they believed that victory was bestowed from above. In more recent times, duels began to replace court verdicts. Over time, this form of dueling was canceled, but honor duels arose. It happened in the sixteenth century.

The way to sort things out with the help of a duel became so popular that during the years 1601-1609 more than 2000 noble French nobles were killed in duels! Church and secular authorities condemned this custom, and in 1602 the French king issued a decree according to which those who challenged a duel, accepted a challenge, or participated in a duel as a second, would be put to death. This measure seemed too harsh, and in 1609 it was established that permission to duel must be obtained from the king.

In England, dueling also became widespread, but here, too, they were outlawed, thanks to numerous protests. However, in Germany, student duels persisted until relatively recently. Students considered it an honor to take part in them.

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. ... >>

Innovative silicon supercapacitor 19.11.2013

The innovative supercapacitor design, created by material scientists at Vanderbilt University (USA) under the guidance of Assistant Professor Cary Pint, makes it possible to create photovoltaic cells capable of generating electricity around the clock and not only when the sun is shining.

It is claimed to be the first supercapacitor made entirely from silicon and along with the microelectronic circuit it powers. And it can be used in built-in mobile phone batteries that charge in seconds and last for weeks between charges.

Scientists believe it will be possible to build batteries from the excess silicon found in today's photovoltaic cells, sensors, mobile phones and many other electromechanical devices, reducing the cost of these devices.

"If you ask people to make a supercapacitor out of silicon, they'll tell you it's a crazy idea," said Carey Pint, an assistant professor in the department of mechanical engineering who led the study. "But we've discovered a simple way to do it."

Instead of storing energy in chemical reactions, as batteries do, supercapacitors store energy by collecting ions on the surface of a porous material. As a result, they have the ability to charge and discharge in minutes rather than hours, and last for several million cycles rather than the thousands of cycles that batteries can.

These properties have enabled supercapacitors made from activated carbon to capture several niche markets, such as storing the energy generated by regenerative braking systems in buses and electric vehicles and providing the surge current needed to regulate the blades of giant wind turbines as wind conditions change. Supercapacitors still lag behind lithium-ion batteries in terms of specific capacity, so they are still too bulky to power most consumer devices. However, they are developing rapidly.

"Building high-performance functional devices from nanoscale building blocks with any level of control proved to be quite a challenge. And once it was done, it proved difficult to repeat," explained Assistant Professor Cary Pint.

“Despite the excellent performance of the device that we got, our goal was not to create devices with record parameters,” Pint said. “The goal was to develop methods for creating integrated energy storage. Silicon is an ideal material to work with, because it is the basis for many modern technologies and devices. In addition, most of the silicon in existing devices remains unused due to the fact that it is very expensive and unprofitable to produce thin silicon substrates."

Pint's group is now using this approach to create an energy store that could be formed in excess material or on the back of photocells and sensors. Supercapacitors could store excess electricity generated by photovoltaic cells during the day and release it during peak hours in the evening.
