Pythagoras: All is Number the Music of the Spheres Intervals
between harmonious musical notes always have whole number ratios.
Playing half a length of a guitar string gives the same note as the
open string, but an octave higher; a third of a length gives a
different but harmonious note; etc. Non-whole number ratios, on the
other hand, tend to give dissonant sounds. Pythagoras described the
primary building blocks of musical harmony: the octave (1:1), the
perfect fifth (3:2), the perfect fourth (4:3) and the major third
(5:4). Pythagoras at his Monochord:

There is a single general space, a single vast immensity which
we may freely call void: in it are innumerable globes like this on
which we live and grow, this space we declare to be infinite, since
neither reason, convenience, sense-perception nor nature assign to
it a limit. Giordano Bruno Quoted in Joseph Silk, The Big Bang
