File:Vincenzo Viviani.jpg|link=Vincenzo Viviani (nonfiction)|1622: Mathematician and scientist [[Vincenzo Viviani (nonfiction)|Vincenzo Viviani]] born. In 1660, Viviani and Giovanni Alfonso Borelli will conduct an experiment to determine the speed of sound. Timing the difference between the seeing the flash and hearing the sound of a cannon shot at a distance, they will calculate a value of 350 meters per second (m/s), considerably better than the previous value of 478 m/s obtained by Pierre Gassendi.
