Apprendimento attivo nel laboratorio di fisica con Arduino e smartphone - Active learning in the physics lab with Arduino and smartphones
No full textLe schede Arduino e gli smartphone costituiscono un’importante risorsa,
a costi contenuti, per attuare politiche di apprendimento attivo, nelle quali
studenti e studentesse partecipano attivamente alla realizzazione di esperimenti di fisica, costruendo gli apparati, conducendo le misure e analizzandole. L’utilizzo di queste risorse consente lo sviluppo di numerose abilità trasversali, spendibili sul mercato del lavoro di una nazione come la nostra, ed `e un ulteriore mezzo di contrasto alle disuguaglianze e alla diffusione di stereotipi di genere. L’impiego di queste risorse e di metodologie di apprendimento attivo si rivela utile anche per coinvolgere nelle attività chi non è particolarmente vocato ad acquisire competenze tecnico-scientifiche, grazie alla possibilità di contribuire alle diverse fasi di un esperimento con competenze trasversali, coinvolgendo manualità, creatività, fantasia e abilità comunicative
A ball pool model to illustrate the Higgs physics to the public
No full textA simple model is presented to explain Higgs boson physics to the grand public. The model consists of a children’s ball pool representing a Universe filled with a certain amount of the Higgs field. The model is suitable for usage as a hands-on tool in scientific exhibits and provides a clear explanation of almost all the aspects of the physics of the Higgs field interaction with other particles
Unveiling the Higgs mechanism to students
No full textIn this paper we outline a lecture given to undergraduate students to explain why physicists are so interested in the Higgs boson. The lecture was conceived for students not yet familiar with advanced physics and is suitable for those studying several other disciplines. The Higgs mechanism is introduced through semi-classical arguments mimicking basic field-theory concepts, assuming the validity of a symmetry principle in the expression of the energy of particles in a classical field. The lecture is divided into two parts. The first, suitable even for high-school students, shows how the mass of a particle results from a dynamical effect caused by interaction between a massless particle and a field (as in the Higgs mechanism). The audience for the second, much more technical part consists mainly of teachers and university students from disciplines other than physics. © 2012 IOP Publishing Ltd
Matter and interactions: A particle physics perspective
No full textIn classical mechanics, matter and fields are completely separated; matter interacts with fields. For particle physicists this is not the case; both matter and fields are represented by particles. Fundamental interactions are mediated by particles exchanged between matter particles. In this article we explain why particle physicists believe in such a picture, introducing the technique of Feynman diagrams starting from very basic and popular analogies with classical mechanics and making the physics of elementary particles comprehensible even to high school students, the only prerequisite being a knowledge of the conservation of mechanical energy. © IOP Publishing Ltd
