On dust, fogs, and particles: The history of the cloud chamber
Full text linkIn this paper we give a brief overview of the history of the Wilson cloud chamber from its development in the late 19th century as a device for estimating the number of dust particles in the foggy cities of the Victorian age to its glorious entry into the emerging fields of nuclear and particle physics in the 1920s and 1930s. Although the cloud chamber is no longer used in cutting-edge physics or university teaching, this device could play a new role in physics education, for example in meteorology and climate studies, and as a historical case study for teaching aspects of the nature of science
The lost notebook of Enrico Fermi: the true story of the discovery of neutron-induced radioactivity
No full textThis book tells the curious story of an unexpected finding that sheds light on a crucial moment in the development of physics: the discovery of artificial radioactivity induced by neutrons. The finding in question is a notebook, clearly written in Fermi's handwriting, which records the frenzied days and nights that Fermi spent experimenting alone, driven by his theoretical ideas on beta decay. The notebook was found by the authors while browsing through documents left by Oscar D'Agostino, the chemist among Fermi's group. From Fermi's notes, they reconstruct with skill and expertise the detailed timeline of the critical days leading up to his vital discovery. While much is already known about the road that led Fermi to his important result, this is the first time that it has been possible to reconstruct precisely when and how the initial evidence of neutron-induced decay was obtained. In relating this fascinating story, the book will be of great interest not only to those with a passion for the history of science but also to a wider audience
