Leonardo Da Vinci: he was interested in a means by which mancould fly and thus he studied the flight of birds.
Bionics: Applying biological principles to the study and design of engineering systems
Galileo Galilei: interested in the strength of bones and suggested that bones are hollow for this affords maximum strength with minimum weight.
Biomechanics : ”mechanics applied to biology”
The development, extension and application of mechanics for the purposes of understanding better physiology and pathophysiology as well as the diagnosis and treatment of disease and injury.
That is, the overall goal of biomechanics is, and must remain, the general improvement of the human condition.

How will humans respond to the altered loads associated with space travel?
Biomechanics aims to explain the mechanics of life and living.
From molecules to organisms, everything must obey the laws of mechanics.
