"In the beginning there was a number" - so you can start a story about ... .music!
There is such a popular classical stereotype about human nature - the division into "rational" physicists and "emotional" lyricists.
But music, which seems to be the embodiment of emotionality, just proves the opposite.
"In the beginning there was a number" - so you can start a story about ... .music! The idea of "verifying harmony by algebra" is traditionally attributed to Pythagoras.
Music has existed since time, as there was a sound and the ability to perceive and reproduce it. But before Pythagoras, no one thought from the scientific point of view about why some musical harmonies are pleasant on hearing, and some sound sharply and even irritate. For his experiments Pythagoras used a monochord tool, which he himself invented.
Monochord had two strings, one with the same tone, and the other with a simple mechanism could change its sound. Changing the proportional relationship of two sounding strings, Pythagoras came to the fundamental conclusion for the entire history of music - the proportion is directly related to sound, and the quality of this sound is expressed in number.
For Pythagoras and his followers, mathematics was a science that opened the law of beauty of the universe, and music allowed to sound this law.
The whole world has proportions, which means it sounds. Today the idea of "harmony of spheres" is perceived as a beautiful metaphor, but in fact it has a very specific meaning: the planets make sounds when moving, and these sounds are related to each other as musical harmonies.
According to the legend Pythagoras was the one who could hear this "heavenly music".
But how, for example, could the number Pi sound? Not indifferent to music and to mathematics David McDonald took the number "Pi" and compared each successive number with a note, added harmony of the left hand and this is the sound series. A series of "infinite" harmony, if we recall the essence of the number Pi))
