Why did the Mint of England mint a series of coins for the guitarist of Queen?

Queen guitarist Brian May has always used a sixpence coin instead of a pick. According to the musician, the pick is too flexible, and another advantage of this coin is its serrated edges, which helps to extract a special grinding sound from the strings. And although the sixpence was officially discontinued in 1970, the Royal Mint released another series of them especially for May's solo tour in 1993.

Why did the Chinese women of Jiangyong county use a script hidden from men for a long time?

Since ancient times, Chinese women living in Jiangyong County, Hunan Province, had a special writing system called Nu-shu, carefully hidden from men. Since women were forbidden to study official letters, they invented their own set of characters corresponding to individual syllables, and this knowledge was transmitted to girls only from their mothers or sisters. To prevent men from discovering the cryptography, nu-shu signs were most often woven into the ornament - their very shape was optimal for embroidery on fabric.

Solidification of bulk substances 30.04.2024

There are quite a few mysteries in the world of science, and one of them is the strange behavior of bulk materials. They may behave like a solid but suddenly turn into a flowing liquid. This phenomenon has attracted the attention of many researchers, and we may finally be getting closer to solving this mystery. Imagine sand in an hourglass. It usually flows freely, but in some cases its particles begin to get stuck, turning from a liquid to a solid. This transition has important implications for many areas, from drug production to construction. Researchers from the USA have attempted to describe this phenomenon and come closer to understanding it. In the study, the scientists conducted simulations in the laboratory using data from bags of polystyrene beads. They found that the vibrations within these sets had specific frequencies, meaning that only certain types of vibrations could travel through the material. Received ... >>

Implanted brain stimulator 30.04.2024

In recent years, scientific research in the field of neurotechnology has made enormous progress, opening new horizons for the treatment of various psychiatric and neurological disorders. One of the significant achievements was the creation of the smallest implanted brain stimulator, presented by a laboratory at Rice University. Called Digitally Programmable Over-brain Therapeutic (DOT), this innovative device promises to revolutionize treatments by providing more autonomy and accessibility to patients. The implant, developed in collaboration with Motif Neurotech and clinicians, introduces an innovative approach to brain stimulation. It is powered through an external transmitter using magnetoelectric power transfer, eliminating the need for wires and large batteries typical of existing technologies. This makes the procedure less invasive and provides more opportunities to improve patients' quality of life. In addition to its use in treatment, resist ... >>

The perception of time depends on what one is looking at 29.04.2024

Research in the field of the psychology of time continues to surprise us with its results. Recent discoveries by scientists from George Mason University (USA) turned out to be quite remarkable: they discovered that what we look at can greatly influence our sense of time. During the experiment, 52 participants took a series of tests, estimating the duration of viewing various images. The results were surprising: the size and detail of the images had a significant impact on the perception of time. Larger, less cluttered scenes created the illusion of time slowing down, while smaller, busier images gave the feeling of time speeding up. Researchers suggest that visual clutter or detail overload can make it difficult to perceive the world around us, which in turn can lead to faster perception of time. Thus, it was shown that our perception of time is closely related to what we look at. Larger and smaller ... >>

Weakening of the bones - an obstacle to deep space flights 16.01.2018

An additional obstacle to human flight to distant objects in the solar system was discovered by scientists at the Charité clinic in Berlin. It turned out that in addition to the weakening of bone tissue, as well as the danger caused by solar and cosmic radiation, they may be disturbed by such a factor as space fever that occurs in weightless conditions.

Doctors studied the data of astronauts who worked on the International Space Station, and came to the conclusion that the temperature rises not immediately upon arrival at the ISS, but after several months. On average, the difference between the cosmic and terrestrial temperatures of the test subjects is one degree, that is, astronauts usually have 37 ° on board. One of the participants in the study, Hanns-Christian Gunga, also notes that during exercise, the temperature of the astronauts on board sometimes jumped up to 40 °.

He notes that the study was round-the-clock, with 11 people taking turns taking part in the experiment. To do this, sensors were used to record the slightest temperature changes in arterial blood, which were pasted to the members of the space crew on the forehead. These sensors showed the slightest fluctuations in the core body temperature in microgravity.

As a result, scientists came to the conclusion that the temperature on board the ISS increased for a number of objective reasons, factors in the absence of certain earthly conditions. For example, the required rate of evaporation of sweat, which should cool the body.
