The Music Of The Cosmos Poem by Paul Hartal

Although inaudible to most of us,
Pythagoras and Kepler heard the songs
of the universe, the music of the spheres.
In "The Harmony of the Spheres", Pythagoras
25 centuries ago advanced the theory
that in their orbital revolution,
the Sun, the Moon and the planets
emit unique celestial sounds
that are imperceptible to the human ear.

Many centuries later, Kepler published
his "Harmonices Mundi" (1619) ,
in which he founded the harmonic system
of the solar system on geometry.
From his geometrical model of the heavens
and the earth, Kepler derived a cosmology
based on musical intervals and musical motion.

In the Theory of Quantum Mechanics
wave-particle duality and matter waves play
a central part. It is believed that all matter
can behave in wave-like manner.
In 1924 Louis de Broglie proposed the idea
that matter behaves like a wave
and this was later also
experimentally demonstrated.
