INTERACTIVE EXPERIMENTS AND EXHIBITS

In the Department of Physics visitors find many apparatuses with which they can interact directly and perform interesting and spectacular experiments. Among these we find:

- a permanently oscillating Foucault pendulum, the only one of its kind in Sardinia, a product of high technology with which it is possible to observe in real time the rotation of our planet around its axis;
- an experiment in remote transmission of audio signals by means of a laser beam;
- a high-power "electromagnetic cannon" that sets off the powerful repulsive forces that can take place between two impulsive high-intensity magnetic fields;
- the possibility of "charging" a person at 75,000 volts;
- a perfect and working copy of Pacinotti's dynamo, with which a radio can be powered;
- a Tesla transformer that produces tensions of about 1,000,000 volts;
- an experiment in remote transmission of weak sounds by means of two large parabolic mirrors;
- experiments in light interference and diffraction;
- an experiment in which objects at the focus of one of several burning-glasses are set on fire;
- experiments in transmission and receiving of electromagnetic waves with the same apparatuses by means of which Marconi developed radiotelegraphy;
- a reconstruction of a 1930s research laboratory, with working optical spectrographs; ...continues
