The physics of bones and muscles:
Borelli, a practicing mathematician and engineer as well as a physician, analyzed the musculoskeletal system in terms of the mechanics of the lever and other simple machines. Borelli studied under Galileo’s student Castelli, along with Torricelli. He was a member of the Accademia del Cimento (Academy of Experiment) in Florence, and worked on hydraulics under the patronage of the Grand Duke.
Physicians such as Santorio and Borelli applied to medicine the physical principles which occupied Galileo in his physics.
This work was published with financial support from Queen Christina of Sweden, who retained Borelli as her physician while she lived in Rome.
