The scientist and his work by D. AMATI and S. FUBINI. A socially engaged scientist by V. F. WEISSKOPF. This week, we pay homage to Albert Einstein, the giant of twentieth-century physics born exactly 100 years ago on 14 March 1879 in Ulm, Germany. At the height of his career, Einstein made a whole series of monumental contributions to physics, including the elaborate theories of special and general relativity which revolutionized human thought and marked a major breakthrough in our understanding to the Universe. Along with quantum mechanics, relativity is one of the twin pillars of understanding which allow us here at CERN to study the behaviour of the tiniest components of matter. The development of quantum mechanics took the combined efforts of some of the greatest scientists the world has known, while relativity was developed almost single-handed by Einstein. The centenary of his birth is being commemorated all over the world. Exhibitions and symposia are being organized, books published, postage stamps issued, statues unveiled, and television documentaries screened. Here at CERN, M. Fierz and V. Weisskopf will present their own tributes to the great man on Monday evening 12 March at 20.00 in the Main Auditorium..

Jean BERNARD est ne a Paris en 1907. Il fait ses etudes a la Faculte des Sciences et de Medecine. Il a consacre une oeuvre considerable aux developpements des recherches et des connaissances sur les causes et les traitements des maladies du sang. Ses principaux travaux sont sur les leucemies. La medecine a plus change pendant les 40 dernieres annees que pendant les 40 siecles precedents. Certains de ces progres meritent une analyse particuliere. Les echecs ou les demi-echecs doivent etre examines. Les voies futures de la recherche biologique et medicale sont pour une large part inspires par ces echecs. Les consequences economiques et sociales des progres de la medecine : economiques, les depenses de la sante croissant plus que le produit national brut. Les remedes efficaces doivent etre discutes. Morales, avec les trois maitrises a acquise ou va acquerir, maitrise de l'heredite, maitrise de la reproduction, maitrise du systeme nerveux..

On December 4 1930, Wolfgang Pauli addressed an "open letter" to Lise Meitner and others attending a physics meeting, suggesting the neutrino as a way out of the difficulties confronted in beta rays research, especially by the existence of a continuous beta spectrum. He proposed a new particle later called the neutrino. The prehistory leading up to Pauli's letter will be reviewed, as well as the later discovery of the electron-neutrino followed by the muon-neutrino. There are now believed to be three different types of neutrino and their anti-particles. Neutrinos have a spin 1/2; but only one spin component has been found in nature: neutrinos go forward as "left-handed" screws and anti-neutrinos as "right-handed" ones. A question still not convincingly resolved today is wether neutrinos have a mass different from zero and, if they do, what consequences this would have for the behaviour of neutrinos and for cosmology..
