Galileo Galilei’s (1564-1642) conceptual models and experimental techniques evolved within rich Italian medieval and Renaissance traditions. This course will review Galileo’s major discoveries in astronomy and mechanics, and examine both the intellectual framework and the vocational context in which he achieved these advances. Discussion primarily of his two major works, Dialogue Concerning the Two Chief World Systems (1631) and Dialogues Concerning Two New Sciences (1638) will be accompanied by visits to related historical sites in and near Florence.

The wool industry helped create the conditions for Florence’s leading role in the rediscovery and interpretation of ancient wisdom. As early as the twelfth century hydraulic engineers were learning to harness the power of the Arno river in extensive mills. We will visit the the startling intact remains of a wool fulling mill in Rimole, dating from the fourteenth century. The skill of water engineers will also be on display in the underground aqueduct system in Siena. The bottini date from the twelfth century. Commercial activity fostered not only technical progress, but also conceptual advance. The careful keeping of ledgers is recognizeable as a significant forerunner of scientific abstract mathematical modeling. We will be treated to a display of fourteenth century accounting from the merchant Francesco Dattini in the Dattini Archive in Prato.

We will visit and analyze Filippo Brunelleschi’s (1377-1446) dome, his wondrous early fifteenth century engineering and organizational feat. Not surprisingly, Renaissance military exigencies dramatically influenced the march of science. Fortifications were drastically altered with the advent of cannons, requiring advanced geometrical and material science expertise. In Florence and Siena we will observe the work of master military engineers Sangallo (1483-1546) , Peruzzi (1481-1536) – and Michelangelo (1475-1564).

Galileo’s military compass represented a culmination of centuries of progress in astronomical and multi-purpose instrument building. Among the examples we will view are the meridian line of Brunelleschi’s friend Toscanelli in the Florence duomo, the armillary of Egnazio Danti (1536-1586) on the façade of Santa Maria Novella, his astrolabe in the Science History Museum in Florence, and numerous additional instruments (including Galileo’s) in the same museum. The influence of art will be addressed in a visits to the Uffizi Museum. In the Palazzo Vecchio, in addition to witnessing the cartographical skill of Danti we will penetrate into some of the building’s sixteenth century engineering design. The nearby church of Santa Croce houses Galileo's tomb and memorial - opposite the tomb of Michelangelo. The group will ascend the hills in the south of Florence to visit Galileo's home in Arcetri and the nearby convent of San Matteo where his beloved daughter Suor Maria Celeste lived until her death in 1634.

For college teachers of: physics, astronomy, economics, history, art history, science history, mathematics, engineering, philosophy. Prerequisites: participants are urged to read a biography of Galileo and familiarize themselves with some aspects of Northern Italian Renaissance history. A recommended reading list will be provided for those who wish to explore in more depth before the trip.

Dr. Salisbury is a theoretical relativity physicist with a special interest in the history of science. He has contributed frequently to Austin College core courses dealing with scientific heritage, and has conducted three January term courses on site in northern Italy on the Life and Times of Galileo.

Dr. Settle is one of the world's leading Galileo scholars. Based now at the Florence History of Science Museum he has for many years explored and written about the deep Tuscan roots of modern science.
