Career

Vittorio Francesco Stancari was born in Bologna in 1678. In 1698 he became a professor of mathematics at the University of Bologna.[1] Stancari was one of a group of young men at the University who became interested in the techniques of Cartesian geometry and differential calculus, and who engaged in experiments and astronomical observation. Others were Eustachio Manfredi, his brother Gabriele Manfredi and Giuseppe Sentenziola Verzaglia. Of these, Gabriele Manfredi developed the most advanced understanding of mathematics.[2] Stancari was awarded the chair of infinitesimal calculus in Bologna in 1708.[3] He died in Bologna in 1709, aged about 31.[1]

Work

Stancari's dissertations and manuscripts show that he applied Leibnizian calculus to problems of physics, hydrodynamics, meteorology and mechanics.[3] He was also aware of Sir Isaac Newton's Principia Mathematica, and discussed Newton in lectures before the Accademia degli Inquieti in Bologna.[4]

Stancari developed a method of measuring the pitch of sound in 1706, using foil that was excited into vibration by rotating toothed wheels.[1] Stancari and Eustachio Manfredi discovered the comet C/1707 W1 in the evening of 25 November 1707. They described it as visible to the naked eye, white, irregular and with a short, faint tail. It had the same apparent size as Jupiter.[5] Stancari experimented with Guillaume Amontons' air thermometer, where air in the bulb pushes up a column of mercury as it expands due to rising temperature. He discovered that the humidity of the air in the bulb had a significant effect on the readings.[6]
