opened the celebrations for the bicentenary of the invention of the stack (1999), the Cabinet has a rich collection of original instruments from the Physics Laboratory of Alessandro Volta, who taught Physics at Pavia from 1778. On one side of the room, two tables of the same work by hosting a few examples of the many tools that he used to investigate the properties of the electric charge and electrified bodies: electrophoretic, electroscope electroscope straws and caps, electrometers, traps, pictures of Franklin and conductors of various forms. We also find some copies of the pile of Volta (the originals were destroyed in a fire in Como in 1899), a number of Leyden jars (single or in series), an electrostatic machine Nairne, of eudiometer, guns and a unit of Time to study the expansion of gases (turn determines the law of isobaric expansion ten years before Gay-Lussac). At the center of the room, two windows contain mechanical and pneumatic tools belonging to the high school "Ugo Foscolo" in Pavia: equipment for the study of motion on an inclined plane and for the study of elastic collisions, pulleys, pumps, a fountain and a flashing device to evaluate the resistance of air. These instruments are purchased or built by Volta and were transferred to high school when, in the mid-nineteenth century, a reform of the school assigned to high school teaching of mechanics. The collection of some Cabinet cabinets containing tools Electrology (Lane and bottles of Leiden, magnets, magnets, dry cells), and mechanical thermology (hydrostatic balance precision calorimeter of Lavoisier and Laplace, thermometers and barometers, a tube Newton), optics (mirrors, lenses, prisms, microscopes, telescopes) and two samples of the meter and kilogram, respectively.
