At a precise moment, in a certain point of the globe
a drop of water
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.
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.
