The universe appears
like a space time continuum, permanently and gradually modifying
its form. Nature possesses unlimited resources of time and
has used millions of years for building up the present front
of cumulated time.
Through all scales of space
and time, from the galaxies down to the elementary particles
and passing by the forms of thinking, these forms will
express the crossing of rhythms with peculiar environments.
They are the transitory and ephemeral signatures of various
singularities of the space time continuum.
Development of the
Such temporal front propagates
sinuously like a battle front under the assaults and rhythms
of various local temporalities. Physic cannot formalise
such cumulated time but only the forces that work out
within a differential manner this front of cumulated time.
The cumulated development
of these forms is described by S shaped curves, called
sigmoid curves. These curves are characteristic of the
auto-catalytic reactions that prevail within the living
phenomena. They are represented through all cultures of
the world, like in India with the symbol of the Swastika
that represents the dynamic crossing of two sigmoid curves.
