A brief report of the history of the discovery of Nuclear magnetic resonance, which underlines the important effect on the post-war world physics in the field of the basic research work on microwaves and electronics done at the MIT ‘Radiation Laboratory’. […]
Until the nineteenfifties the general aim of science was the search for universal natural laws. In the sixties a radical change took place: advanced scientific research in many traditional subjects started to investigate the evolution of complex systems and of unpredictable and unrepeatable processes. […]
Bonacini prize 1995/96: “From the merry-go-round to the satellite: forces acting on rotating bodies”. The article, taken from the report of the first classified work. describes three experiments: the growth of small wheat plants on a turntable rotating night and day, […]
A simple low cost autonomous apparatus for measuring Planck’s constant is described. Although the precision is not high, the experiment shows how the quantization of radiant energy is deduced from the properties of a black body, in a way very close to the history of Planck’s discovery. […]
The history of external radiation beam therapy and its important developments are briefly outlined. The physical bases of the use of ion beams, which offer several advantages over photons in the treatment of well localized cancer, are explained. […]
High school pupils? interest in physics and their understanding of the subject is disappointing if the teacher follows a teaching tradition that treats the subject as a bare technique that doesn?t motivate the learners and is unable to introduce them to critical thought. […]
