Why seven notes?

The ancient Greek mathematician and philosopher Pythagoras of Samos, who lived around 570-500 BC, built a special musical and mathematical instrument, which he called a monochord, which means "single-string".

The instrument was a long resonator box to amplify the sound, with a single string strung over the box. Under the string was a stand, moving which, Pythagoras could divide the string into parts.

First of all, Pythagoras divided the string into two equal parts. Comparing the pitch of the whole string and its half, he was amazed: the whole string and half of it sounded very similar, an amazing consonance was obtained. A string that was half as long sounded much higher, but in the same tone as the whole string. As if the same sound, born at the same time high female and low male voices.

He divided the string into two more parts. The new half of the string gave the same sound, merging with the previous ones, only even higher. As if a child's voice, singing the same note, joined the male and female voices.

Much later, the distance between the lower and upper tones of this absolutely harmonious consonance began to be called an octave, which in Latin means "eighth" or simply "eight". But why exactly eight and not six or nine?

Pythagoras explored not only halves of a string. He divided the string into three, four, five equal parts... At the same time, he received sounds of different heights. Pythagoras arranged these sounds-tones along the height with sort of steps of a sound ladder. And the ancient mathematician turned out that eight sounds-steps fit in an octave. And these eight sounds, which later received the names DO - RE - MI - FA - SOL - LA - SI and again DO, are necessarily repeated within each octave. This series of sounds - the scale - later became known as the Pythagorean scale, or the Pythagorean scale.

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 ... >>

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. ... >>

Skyscraper with wind turbines 19.04.2002

A group of European designers proposes a skyscraper project with six wind turbines built into the building. The aerodynamic shape of the three towers directs the wind to the turbines.

The designers expect that the building will be able to supply itself with electricity and something else will be left for the neighbors. But what will it be like to live with constant noise and vibration?
