A raindrop
At a precise moment,
in a certain point of the globe
a drop of water
is descending
from a cloud to the ground.
Its future is
completely prescribed by the Natural Law.
And its past too.
What will happen
in the next second is absolutely certain.
Likewise what
happened up to now has always
been precisely defined.
Let's make an effort to "imagine"
the history of our drop.
The tiny
droplets forming a cloud
are already water
in liquid state their very
small size however allows them to float.
When some of
them unite and their weight grows,
the downward movement
to the ground starts.
It is attracted by
the earth; it meets the friction of the air.
It can change its
course depending on the currents
of the air it encounters.
Even with our
imperfect instruments
we could follow
its movement and to some
extent predict its further course.
Its story is a
brief one.
Depending on the
height of the cloud
it may be a few minutes or more.
That which is worth further study
is the story of the water composing our drop.
