Igor Tamm 1895 - 1971 Awarded the Nobel Prize for Physics in 1958
Igor Tamm 1895 - 1971 Awarded the Nobel Prize for Physics in 1958 The famous Russian physicist Igor Evgenievich Tamm is best known for his theoretical explanation of the origin of the Cherenkov radiation. But really his works covered various fields of physics: nuclear physics, elementary particles, solid-state physics and so on. In about 1935, he and his colleague, Ilya Frank, concluded that although objects can’t travel faster than light in a vacuum, they can do so in other media. Cherenkov radiation is emitted if charged particles pass the media faster than the speed of light ! For this research Tamm together with his Russian colleagues was awarded the 1958 Nobel Prize in Physics. Igor Tamm was born in 1895 in Vladivostok when Russia was still ruled by the Tsar. His father was a civil engineer who worked on the electricity and sewage systems. When Tamm was six years old his family moved to Elizavetgrad, in the Ukraine. Tamm led an expedition to He graduated from the local Gymnasium in 1913. Young Tamm dreamed of becoming a revolutionary, but his father disapproved . However only his mother was able to convince him to search for treasure in the Pamirs change his plans. She told him that his father’s weak heart could not take it if something happened to him. In 1923 Tamm was offered a teaching post at the Second Moscow University and later he was And so, in 1913, Tamm decided to leave Russia for a year and continue his studies in Edinburgh. awarded a professorship at Moscow State University. -

Ar Thur Koestler and Mysticism
AR THUR KOESTLER AND MYSTICISM by NILS BJORN KVASTAD ARTHUR Koestler was an influential writer during the first years after the war. His attacks on communism got a world-wide echo, in particular among intellectuals. To the reading public he was in the first place a political writer. But according to himself the political content is only one aspect of his literary production from his first years as an author. As important were some mystical experiences he had while sitting in one of Franco's prisons awaiting execution during the Spanish Civil War. These experiences had for him certain ethical impli cations, and an important theme in his first books was the contrast between the ethics derived from his mystical experiences on the one hand and Marxist-Leninist ethics as well as the ethical implications of Freudian psychoanalysis on the other. In his autobiography Koest ler writes about how his first books were influenced by his mysti cal experiences, or the 'hours by the window' as he called them: 'In the years that followed I wrote a number of books in which I at tempted to assimilate the (mystical) experiences of cell no. 40. Ethical problems had hitherto played no part in my writing, now they became its central concern. In 'The Gladiators', ( ...), and 'Darkness at Noon', ( .•. ), I tried to come to intellectual terms wi th the in tuiti ve glimp ses gained durin g the 'hours by th e win dow'. Both novels were variations on the same theme: the problem of Ends and Means, the conflict between transcendental morality and social expediency. -

From Budapest to New York: The Odyssey of the Polanyis Judith Szapor This article is a short version of Chapter 4 of my manuscript, entitled "The Hungarian Pocahontas;" The Life and Times of Laura Polanyi, 1882-1959, to be published by the University of Toronto Press. In the preceding chapters I describe the first stages of the Polanyis' Odyssey. It included the emigration from Hungary of Laura Polanyi's brothers, Adolf, Karl and Michael, to Italy, Austria and Germany, respectively. They left Hungary, along with scores of left-wing intellectuals, during the period of right-wing repression that followed the post-war demo- cratic and Bolshevik revolutions. By 1939, both Michael and Karl had settled in England. As for Laura Polanyi's immediate family, in the late 1920s and early 1930s her children, Michael, Eva and George Strieker all studied and worked in Austria and Germany. While the latter, her youngest was completing his studies at the University of Vienna, Michael and Eva took a detour to the Soviet Union. By 1932, both had taken up positions as "foreign experts," Michael as a patent expert in Moscow, Eva as a designer, eventually working for the Lomonosov Porcelain Factory in Leningrad. Although keeping her homes in Budapest — where her husband lived — and Vienna, Laura accompanied her children to the Soviet Union for extended periods of time. She was there when, in May 1936, Eva was arrested and accused with participating in a plot to assassinate Stalin. Fourteen months later, in September 1937, when Eva was released and expelled from the Soviet Union, the family gathered in Vienna, preparing to leave for the United States. -
The Making of the Standard Theory
August 11, 2016 9:28 The Standard Theory of Particle Physics - 9.61in x 6.69in b2471-ch02 page 29 Chapter 2 The Making of the Standard Theory John Iliopoulos Laboratoire de Physique Th´eorique, Ecole´ Normale Sup´erieure, 24 rue Lhomond, 75005 Paris, France 1. Introduction The construction of the Standard Model, which became gradually the Standard Theory of elementary particle physics, is, probably, the most remarkable achieve- ment of modern theoretical physics. In this Chapter we shall deal mostly with the weak interactions. It may sound strange that a revolution in particle physics was initiated by the study of the weakest among them (the effects of the gravitational interactions are not measurable in high energy physics), but we shall see that the weak interactions triggered many such revolutions and we shall have the occasion to meditate on the fundamental significance of “tiny” effects. We shall outline the various steps, from the early days of the Fermi theory to the recent experimental discoveries, which confirmed all the fundamental predictions of the Theory. We shall follow a phenomenological approach, in which the introduction of every new concept is motivated by the search of a consistent theory which agrees with experiment. As we shall explain, this is only part of the story, the other part being the requirement of mathematical consistency. Both went in parallel and the real history requires the understanding of both. In fact, as we intend to show, the initial motivation was not really phenomenological. It is one of these rare cases in which a revolution in physics came from theorists trying to go beyond a simple phenomenological model, The Standard Theory of Particle Physics Downloaded from www.worldscientific.com not from an experimental result which forced them to do so. -
