Galileo’s physics, applied to medicine: Santorio Santorio (also known as Sanctorio or Sanctorius) practiced medicine in Padua, in the Venetian Republic. Santorio, Galileo, Giofrancesco Sagredo and Paolo Sarpi frequently collaborated in empirical investigations and moved in the same intellectual circles in Venice. Santorio designed a number of instruments which applied the principles of mechanical physics to medicine, including a thermos cope, pulsilogium, and weighing chair.
