Introductory video

What is it like to be an engineer in an era of mathematical discovery?

In the Republic of Venice, Galileo’s day-to-day work as a Professor of Mathematics was that of a scientist-engineer. City officials and notable individuals called upon his expertise to solve civic, military and nautical problems in engineering. He addressed practical problems in light of their general significance for physics. His work as a scientist-engineer resulted in new mathematical and scientific instruments, including the military compass, thermoscope and telescope.

Section 1: Scientist-Engineers

Scientist-engineers were mathematicians who grasped the principles of mechanics, the use of mathematical instruments, and the operation of complex machines well enough to apply them to the complex tasks of city life. Their expertise applied to optics, architecture, metallurgy, pneumatics, hydraulics, transport, surveying, ship-building, fortification and the arts of war.

Section 2: Calculation and Measurement

Scientists and engineers thrive upon mathematical innovations in calculation and measurement, as shown in several vignettes from the abacus to the slide rule to the analytical computer.

Section 3: Galileo’s Instruments

Galileo’s engineering compass, thermoscope, microscope and telescope reflect his work as a mathematician, astronomer and scientist-engineer.
