This article is dedicated to the philosophy ofscience which was developed by the outstanding Soviet physicist and leader of a powerful scientificcommunity, L. I. Mandelstam. It is shown that thisphilosophy can be summed up under the heading operationalism. A comparison with the paradigmaticoperationalism of Percy Bridgman is undertaken andthe German positivist roots of Mandelstam's philosophyare indicated. The final section reconstructs the principle ofexpedient idealization, the principle which was putforward by Mandelstam's disciples in the spirit of hisoperationalism to solve problems of (...) the theory ofnon-linear oscillations.

In his 1939 Lectures, the prominent Soviet physicist L. I. Mandelstam proposed an interpretation of quantum mechanics that was understood in different ways. To assess Mandelstam's interpretation, we classify contemporary interpretations of quantum mechanics and compare his interpretation with others developed in the 1930s. We conclude that Mandelstam's interpretation belongs to the family of minimal statistical interpretations and has much in common with interpretations developed by American physicists. Mandelstam's characteristic message was his theory of indirect measurement, which influenced his discussion (...) of the "reduction of the wave packet" and the Einstein, Podolsky, and Rosen argument. This article also reconstructs what lay behind Mandelstam's interpretation of quantum mechanics. This was his operationalism, by virtue of which his interpretation resembled Kemble's, in which the statistical and Copenhagen views had been combined. Like Popper and Margenau, Mandelstam followed R. von Mises's empirical conception of probability. Mandelstam, like the other proponents of the statistical approach to quantum mechanics, was affected by the culture of macroscopic experimentation with its emphasis on statistical measurement.

L.I. Mandelstam, the outstanding Soviet physicist, leader of a prominent and productive scientific community, was educated as a physicist and started as a researcher and an university teacher at Strasbourg University. We consider the intellectual influence of the main currents in contemporary German science on Mandelstam's work in science.

A new interpretation of quantum mechanics, the interpretation which became popular in XXI, has been taken under consideration. This is the quantum baysinism (QBism) which may be taken as an extrapolation of the baysian philosophy of probability over the interpretation of quantum mechanics. The baysian philosophy of quantum mechanics has been compared with the Copenhagen interpretation of quantum mechanics, the interpretation which can been treated as standard as it is represented in the main textbooks. In contrast to the Copenhagen interpretation (...) which proceeds from the triplets – nature, apparatus and observer (agent), QBism emphasizes the conscious of the observer: the quantum state is the observer’s state, and by means of the quantum conceptual technique the observer constructs his/her own image of quantum processes. By means of measurement the observer updates his/her quantum state, the measuring apparatus being an extension of the observer’s sensuality. From the point of the QBism’s view the phenomenon of decoherence which is widely discussed in the contemporary literature is not essential for the theory of measurement in quantum mechanics. The decoherence explains why the macroscopic phenomena don’t expose the interference behavior which is characteristic for quantum superposition. From the historicо-philosophical point of view Qbism can be traced back to American instrumentalism and operationalism. (shrink)

In the Soviet scientific literature of 1920‒30 the concept of probability was holly debated. The frequency concept which was proposed by R. von Mises became popular among Soviet physicists belonging to the L.I. Mandelstam community. Landau and Lifshitz were also close to this concept in their famous course of theoretical physics. A.Khinchin, a mathematician who cooperated with Kolmogorov, opposed to the frequency conception. In this paper we try to demonstrate that the frequency position was connected with the anthropomorphous approach to (...) physics, whereas Khinchin’s positions implied the criticism of anthropomorphism and put forward the ideal of objective knowledge.

Mandelstam’s criticism of the Rayleigh theory of the blue color of the sky (1907) and his polemic with M. Planck (1907–1908) did not become notable events in the history of physics. However, the method of their coverage in the Soviet and in the post-Soviet physics literature is remarkable. Most of Soviet physicists and historians of physics supported Mandelstam's point of view in his criticism of both Raleigh and Planck. The situation changed only at the beginning of the 21st century: in (...) the Russian literature the publications appeared emphasizing that in the Raleigh–Mandelstam and Planck–Mandelstam controversies Mandelstam was not right, Raleigh and Planck were closer to the truth. Which presumptions of this trend can be noted? This was patriotism of the scientific school peculiar to Mandelstam’s graduate students and the former graduate students, the patriotism connected with solidarity which helped Mandelstam’s community to survive in the Soviet totalitarian regime and in the totalitarian organization of science. This was also progressionism which was popular among academics and among men in the street. The phenomenon of common knowledge, mutual knowledge among the members of a scientific community should be taken under consideration. Common knowledge is connected with the non-thematized anonymous inclusion of the ideological terminology into scientific discourse. (shrink)

I take the phrase ''the theory of nonlinear oscillations'' to identify a historical phenomenon. Under this heading a powerful school in Soviet science, L. I. Mandelstam's school, developed its version of what was later called ''nonlinear dynamics''. The theory of nonlinear oscillations was formed around the concept of self-oscillations, which was elaborated by Mandelstam's graduate student A. A. Andronov. This concept determined the paradigm of the theory of nonlinear oscillations as well as its ideology, that is, a set of characteristic (...) ideas which, together with the corresponding examples and analogues, allowed the expansion of the theory into associated areas where it indicated new interesting phenomena and posed new problems. It was the ideology that made possible the broader application of the theory of nonlinear oscillations, whose domain was originally lumped systems, to continuous media and its subsequent progress toward synergetics. In the course of its ideological application, the concept of self-oscillations was greatly extended, became vague and diffuse, and related concepts such as self-waves and self-structures appeared.

This biography of the famous Soviet physicist Leonid Isaakovich Mandelstam (1889-1944), who became a Professor at Moscow State University in 1925, describes his contributions to both physics and technology, as well as discussing the scientific community which formed around him, usually called the Mandelstam school. Mandelstam's life story is thereby placed in its proper cultural context. The following more general issues are taken under consideration: the impact of German scientific culture on Russian science; the problems and fates of Russian intellectuals (...) during the revolutionary and post-revolutionary years; the formation of the Soviet Academy of Sciences; and transformation of the system of higher education in the USSR during the 1920's and 1930's.The author shows that Mandelstam's fundamental writings and his lectures notes allow to reconstruct his philosophy of science and his approach to the social and ethical functions of science and science education. That reconstruction is enhanced through extensive use of hitherto unpublished archival material as well as the transcripts of personal interviews conducted by the author. (shrink)

The Belousov-Zhabotinsky reaction is a far-from-equilibrium reaction involving bromine and citric acid that results in the establishment of a nonlinear chemical oscillator. In addition to providing a paradigmatic chemical model of nonequilibrium biological phenomena, the mathematical models of the BZ reaction are theoretically interesting. The present article concentrates on the personal trajectory of Boris Pavlovich Belousov ; it attempts to explain what, in his routine work in applied and industrial chemistry, could have induced his discovery. The second section describes Belousov’s (...) reaction as presented in his short paper in the proceedings of the institute where he was employed , this being the only paper on his reaction that he was able to publish during his lifetime. The third section presents Belousov’s biography. I then discuss Belousov’s biography in the light of the paper representing his reaction. I have tried to find the prerequisites of Belousov’s discovery in his research in analytical chemistry and in toxicology and radiation medicine . The sixth section attempts an explanation of the ideological underpinning of Belousov’s reaction—the dialectics of continuity and discontinuity popular among Soviet scholars at that time. (shrink)

The article takes under consideration three versions of the ensemble interpretation of quantum mechanics and discusses the interconnection of these interpretations with the philosophy of science. To emphasize the specifics of the problem of interpretation of quantum mechanics in the USSR, the Marxist ideology is taken into account. The present paper continues the author’s previous analysis of ensemble interpretations which emerged in the USA and USSR in the first half of the 20th century. The author emphasizes that the ensemble approach (...) turned out to be a dead end for the development of the interpretation of quantum mechanics in Russia. The article also argues that in Soviet Russia, the classical Copenhagen approach to quantum mechanics was used. The Copenhagen approach was developed by Lev Landau in 1919–1931 and became the basis of the Landau-Lifshitz famous course on quantum mechanics, one of the classics of twentieth-century physics literature. Although Vladimir A. Fock’s approach to the interpretation of quantum mechanics differs from the standard presentation by Lev Landau and Evgeny Lifshitz, Fock put forward a very important principle that complementarity is a “firmly established law of nature”. The fundamental writings of Lev Landau, Vladimir Fock and Igor Tamm, the authors of the mid-twentieth century, did a lot to defend the standard point of view such as the popular interpretations by Landau and Lifshitz. This approach can be traced back to Landau’s early writings and to Fock’s criticism of the ensemble approach. (shrink)

Background: The magnitude of bullying and harassment among psychiatrists is reportedly high, yet no peer-review published studies addressing this issue could be found. Therefore, it was decided to conduct a pilot study to assess the degree of the problem, the types of bullying/harassment and to provide some insights into the situation.Methods and Principal Findings: Following multiple focus group meetings, a yes/no response type questionnaire was developed to assess the degree and type of bullying and harassment experienced by psychiatrists. Over a (...) 3-month period the questionnaire was administered to a random sample of 60 psychiatrists. 57 out of the 60 psychiatrists reported harassment and bullying. Frequencies of the following response variables are presented in descending order: rumours 40% ; defamation 20% ; passing remarks 20% ; false accusations 15% ; threats 13.3% ; verbal abuse 13.3% ; unjustified complaints 13.3% ; promotion blocked 13.3% ; humiliation 13% ; bad reference given 10% ; credentials questioned 8.3% ; physical attacks 5% ; termination 5% ; derogatory remarks 1.7% and 1.7% were subjected to personal work. As a result of being subjected to harassment, 66.7% of the psychiatrists did not take any action, whereas 33.3% confronted the person they believed responsible. Asked whether the bullying and harassment caused distress, 18.3% of the psychiatrists did not report any effect, 30% reported mild distress, 40% moderate distress and severe distress was reported by 11.7%.Conclusions: It was concluded that the magnitude of bullying and harassment among psychiatrists may be quite high, as evidenced by this pilot study. There is a need for extensive systematic studies on this subject and to establish strategies to prevent and address this issue at a national and regulatory level. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Philosophy 41.1 (2003) 121-122 [Access article in PDF] Harold Tarrant. Plato's First Interpreters. Ithaca, NY: Cornell University Press, 2000. Pp. viii + 263. Cloth, $55.00. This is Tarrant's third book on the ancient Platonist tradition, following his Scepticism or Platonism? (1985) and Thrasyllan Platonism (1993). In those earlier volumes his focus was on the first centuries bc and ad. Here his scope is much (...) wider. Stating that "Platonic interpretation is today at a crossroads," he has written a book that explores "ancient attempts to wrestle with this corpus," with the ultimate objective "to encourage a fresh, almost primitive reading of Plato himself" (vii).He begins engagingly by confronting the ancients with questions any modern reader of Plato must ask: What kind of text is this? Are there doctrines here? Where do I look for Plato's doctrines? The second part of his book is a historical survey, taking us from Plato, the early Academy and Aristotle, through the Hellenistic and early Roman Imperial period, and concluding with the principal Neoplatonist interpreters. In the third and longest part, he focuses on the interpretation of specific dialogues, giving most space to the Gorgias and Theaetetus, but also dealing in particular detail with the Meno, Parmenides, and Philebus. Something is said about every dialogue, but Tarrant writes only briefly about such major works as the Republic and Timaeus. He explains his selectivity (not very convincingly) as due to his wish to "discuss issues of meta-interpretation, with emphasis on the period before Plotinus" (198).Taking his book as a whole, one realizes that few strands of modern interpretation were not prefigured to quite a large extent in antiquity. The two most obvious exceptions are the chronological and developmental approach (Early, Middle, and Late), at present under strong attack from some quarters, and the theological, numerological, and allegorical readings practiced by Neoplatonists. Plato's ancient interpreters were doctrinal unitarians, but they implicitly anticipated our tendency to distinguish "Socratic dialogues," which some of them called "gymnastic" and "inquisitive," from such "canonical" works as the Phaedo,Republic, Symposium, and Timaeus, to which they applied the labels "dogmatic" and "expository." And they recognized that both types of characteristics could be found in the same dialogue, as in the Meno and Theaetetus. Plato himself, they proposed, spoke primarily through the voices of Socrates, Timaeus, and the Eleatic and Athenian strangers; but other characters, such as Pausanias in the Symposium, or Protagoras in the dialogue of that name, utter thoughts with some philosophical value. In explaining difficult passages of one dialogue, they would typically refer to passages from other parts of the corpus. An especially intriguing instance is the strategy of the Anonymous Commentator on the Theaetetus, who reads the Meno into the dialogue on which he is officially commenting.Ancient scholars, just like ourselves, asked questions about the unifying themes of complex dialogues. Hence the sub-titles given to certain works: "On the soul" for the Phaedo, and "On justice" for the Republic, etc. For Olympiodorus (whose commentary on the Gorgias Tarrant has recently co-edited [Leiden, 1998]), earlier interpreters have seriously erred by giving too limited an account of that dialogue's scope. It is not, he says, simply about rhetoric, nor about justice and injustice; nor is its theme the divine demiurge (as some Neoplatonists had strangely proposed, on the basis of the concluding myth). Rather, the subject of the Gorgias is "the ethical principles that lead to constitutional well-being" (125). [End Page 121] However, Olympiodorus's eminently "sensible" reading (as Tarrant calls it) is deeply embedded in the Neoplatonic contrast between the "purificatory virtues" of the Phaedo and the "constitutional virtues" of Republic4.Strong or weak scepticism, esotericism, unwritten doctrines, spurious versus genuine, a canon of central dialogues, dramatic considerations, and the philosophical importance or non-importance of the dialogues' prologues—all of these are interpretive approaches that Tarrant surveys in this immensely learned book, and all of them continue to resonate for us. Modern scholars, who emphasize the literary and philosophical unity of each dialogue, are walking... (shrink)

During recent years we have seen and assisted at a significantly increased number of twin births. The main reason for this increase in the frequency of twin births is the increasing number of so called “induced pregnancies”, whether through hormonal stimulation or artificial insemination techniques.It is well known1 that twins have high mortality and morbidity rates during the perinatal and the following period. The characteristics of conception and pregnancy can determine the development of several pathologies, including prematurity and intrauterine growth (...) retardation, …. (shrink)

The philosophy of Epictetus, a freed slave in the Roman Empire, has been profoundly influential on Western thought: it offers not only stimulating ideas but practical guidance in living one's life. A. A. Long, a leading scholar of later ancient philosophy, gives the definitive presentation of the thought of Epictetus for a broad readership. Long's fresh and vivid translations of a selection of the best of Epictetus' discourses show that his ideas are as valuable and striking today as they were (...) amost two thousand years ago. This is a book for anyone interested in what we can learn from ancient philosophy about how to live our lives. (shrink)

There are few examples in the literature of objective measures for the assessment of donor willingness. The author describes the scoring system in use at his own renal transplant unit which has brought objectivity to the process of determining the willingness of living related donors. In this system, a total score to determine the degree of willingness or unwillingness is calculated based on responses to a series of questions. The author believes that with minor modifications this system could be implemented (...) by transplant units in different countries and cultures to screen out donors who are acting under duress.

The Western tradition of philosophy began in Greece with a cluster of thinkers often called the Presocratics, whose influence has been incalculable. They include the early Ionian cosmologists, Pythagoras, Heraclitus, the Eleatics (Parmenides, Melissus, and Zeno), Empedocles, Anaxagoras, the atomists and the sophists. All these thinkers are discussed in this 1999 volume both as individuals and collectively in chapters on rational theology, epistemology, psychology, rhetoric and relativism, justice, and poetics. A chapter on causality extends the focus to include historians and (...) medical writers. (shrink)
