    Most physicists know that Rutherford proposed the presence of an atomic nucleus in 1911 when he was in Manchester based on the result of an alpha scattering experiment performed by Geiger and Marsden. However, the first results on alpha scattering were obtained much earlier, during the time Rutherford was at McGill. In a paper Rutherford published in 1906 entitled “Retardation of the alpha ...

    In our time, when problems of population growth, consumption demands and climate change are matters of daily concern, I want to mention some of the ethical problems that have confronted scientists. The fact that any discovery may turn out to have both wonderful and disastrous consequences has been discussed many times before.
    The discovery of nuclear fission brought us both the atomic bomb...

    En 1781, le géologue français Déodat de Dolomieu visite le sud-est de la Sicile afin d’étudier les volcans éteints de la région du Val di Noto. Les résultats de ses recherches furent présentés dans un mémoire, publié en 1784, paru dans les Observations sur la physique, sur l'histoire naturelle et sur les arts par François Rozier (1734-1793). Dans ce mémoire, Dolomieu expose notamment, en...
