Quotation from: The Notebooks of Leonardo Da Vinci

Written by: Leonardo da Vinci


The motion of the air is seen by the motion of the dust thrown up by
the horse's running and this motion is as swift in again filling up
the vacuum left in the air which enclosed the horse, as he is rapid
in passing away from the air.


Perhaps it will seem to you that you may reproach me with having
represented the currents made through the air by the motion of the
wind notwithstanding that the wind itself is not visible in the air.
To this I must answer that it is not the motion of the wind but only
the motion of the things carried along by it which is seen in the
air.
