Under Catherine de Medici, women could not grow or paint their nails - they could be accused of witchcraft. Therefore, the ladies cut their hair short and polished it to a shine with a board tightly covered with suede. Perhaps this is where modern French manicure originates. At first it came down to only care and polishing. Nails became colored only in 1932, when the first red nail polish was invented.

As stated in a published report by Italian scientists, women are contraindicated from approaching stoves, electric kettles, washing machines, dishwashers, coffee makers and toasters. In addition, they should not sit too long in front of the TV or work on the computer for a long time.

According to a study by British psychologist Dr. David Lewis, who conducted a survey among 1000 men, the greatest emotions, and most often positive ones, are caused by a car (36 percent). In second place is football: for 30 percent of men, this sport evokes unbridled delight, tenderness or rage. In third place is money, no matter how much or how little it is and how it was earned (almost 30 percent). And in last place are women. (s-info.ru/General/)

According to experts, there are more than a thousand different varieties of coffee in the world. They are classified according to two criteria: geographical and botanical. newsletter Magazine for men and women

The botanical character is represented by various types of these plants, such as Arabica, Robusta, Liberica, Excels. On the plantations of equatorial countries, the most common type is Arabian or Arabica. newsletter Magazine for men and women

Robusta coffee trees were initially considered wild. They were discovered in the Belgian Congo at the end of the last century. Soon, however, this type of coffee began to be cultivated and today the best varieties are grown in Madagascar and Guinea. The Robusta species received its name for its resistance to coffee rust, which destroyed almost all coffee plantations in Ceylon in the 70s of the 19th century. newsletter Magazine for men and women

The @ sign is a so-called ligature - a connection, a fusion of two letters. Moreover, as reputable dictionaries indicate, this is not a combination of the letters a and t, as the Anglo-Saxons believe. This ligature is of Latin origin, it is the Latin preposition ad, which means, however, approximately the same as the English at - on, at, about, at, in, by, to. Therefore, most likely, the icon originated, if not in Ancient Rome, then no later than the Middle Ages, when Latin was the common language for contacts, including commercial ones, between countries.

The world's tallest astronomical observatory opened 04.05.2024

Exploring space and its mysteries is a task that attracts the attention of astronomers from all over the world. In the fresh air of the high mountains, far from city light pollution, the stars and planets reveal their secrets with greater clarity. A new page is opening in the history of astronomy with the opening of the world's highest astronomical observatory - the Atacama Observatory of the University of Tokyo. The Atacama Observatory, located at an altitude of 5640 meters above sea level, opens up new opportunities for astronomers in the study of space. This site has become the highest location for a ground-based telescope, providing researchers with a unique tool for studying infrared waves in the Universe. Although the high altitude location provides clearer skies and less interference from the atmosphere, building an observatory on a high mountain poses enormous difficulties and challenges. However, despite the difficulties, the new observatory opens up broad research prospects for astronomers. ... >>

Controlling objects using air currents 04.05.2024

The development of robotics continues to open up new prospects for us in the field of automation and control of various objects. Recently, Finnish scientists presented an innovative approach to controlling humanoid robots using air currents. This method promises to revolutionize the way objects are manipulated and open new horizons in the field of robotics. The idea of ​​controlling objects using air currents is not new, but until recently, implementing such concepts remained a challenge. Finnish researchers have developed an innovative method that allows robots to manipulate objects using special air jets as "air fingers". The air flow control algorithm, developed by a team of specialists, is based on a thorough study of the movement of objects in the air flow. The air jet control system, carried out using special motors, allows you to direct objects without resorting to physical ... >>

Purebred dogs get sick no more often than purebred dogs 03.05.2024

Caring for the health of our pets is an important aspect of the life of every dog ​​owner. However, there is a common assumption that purebred dogs are more susceptible to diseases compared to mixed dogs. New research led by researchers at the Texas School of Veterinary Medicine and Biomedical Sciences brings new perspective to this question. A study conducted by the Dog Aging Project (DAP) of more than 27 companion dogs found that purebred and mixed dogs were generally equally likely to experience various diseases. Although some breeds may be more susceptible to certain diseases, the overall diagnosis rate is virtually the same between both groups. The Dog Aging Project's chief veterinarian, Dr. Keith Creevy, notes that there are several well-known diseases that are more common in certain breeds of dogs, which supports the notion that purebred dogs are more susceptible to disease. ... >>

1 Tbps or higher wireless data antenna 13.03.2013

The graphene antenna, which was developed by American scientists, is capable of providing wireless data transfer rates of 1 Tbps and higher and can be used at distances up to 1 m, as well as for data transmission between elements of the same crystal or printed circuit board. Scientists at the Georgia Institute of Technology have designed a graphene wireless antenna that can provide wireless data transfer rates of more than a terabit per second, that is, capable of transmitting several HD-resolution films per second, reports Technology Review.

"This is incredible speed. Today, it takes hours to copy data from one computer to another. New technology can reduce the procedure to a few seconds," commented Ian Akyildiz, head of the technology laboratory at Georgia Institute of Technology wireless connection. However, a graphene antenna is able to provide the specified speed at a short distance - only about 1 m. The smaller the distance, the higher the speed can be. The researchers calculated that at a distance of several centimeters, in theory, speeds of up to 100 Tbps can be achieved.

Graphene is a two-dimensional lattice of carbon atoms that has a honeycomb structure. Electrons in such a lattice move almost without resistance - 50-500 times faster than in a semiconductor. This material is considered promising for the creation of next-generation electronic components. To create an antenna, according to the team of researchers, graphene must be shaped into narrow strips with a width of 10 to 100 nm and a length of 1 micron, which will allow data transmission at the terahertz frequency. Electromagnetic waves at the terahertz frequency will lead to the emergence of plasmonic waves - the oscillation of atoms on the surface of graphene strips - which will allow data to be transmitted and received.

Graphene antennas can also be used to link nanoscale components on the same semiconductor, not just to link two systems. "The graphene antenna can be made much smaller than a conventional wire antenna. It can be a micrometer or a few nanometers in size. The bottom line is that such an antenna can be placed in very small objects," explained Phaedon Avouris, IBM Fellow Emeritus, who leads research in nanotechnology at the IBM Research Laboratory in New York. However, before creating such an antenna, scientists have to solve many problems. "The antenna cannot work on its own. It depends on a lot of other components - such as generators and detectors, amplifiers and filters. All of them must be created on the same scale and made to work at the same speeds in order to get a complete device," - the researchers explained.

A group of scientists from the Georgia Institute of Technology intends to create a prototype antenna within a year, and then add other components to it. The work is scheduled to be published in the IEEE Journal of Selected Areas in Communication in 2013.
