We describe here a series of experimental analogies between fluid mechanics and quantum mechanics recently discovered by a team of physicists. These analogies arise in droplet systems guided by a surface (or pilot) wave. We argue that these experimental facts put ancient theoretical work by Madelung on the analogy between fluid and quantum mechanics into new light. After re-deriving Madelung’s result starting from two basic fluid-mechanical equations (the Navier-Stokes equation and the continuity equation), we discuss the relation with the de (...) Broglie-Bohm theory. This allows to make a direct link with the droplet experiments. It is argued that the fluid-mechanical interpretation of quantum mechanics, if it can be extended to the general N-particle case, would have an advantage over the Bohm interpretation: it could rid Bohm’s theory of its strongly non-local character.

The object of this paper is to look at the extent and nature of the uses of analogy during the ªrst century following the so-called scientiªc revolution. Using the research tool provided by JSTOR we systematically analyze the uses of “analog” and its cognates (analogies, analogous, etc.) in the Philosophical Transactions of the Royal Society of London for the period 1665–1780. In addition to giving the possibility of evaluating quantitatively the proportion of papers explicitly using analogies, this approach makes it (...) possible to go beyond the maybe idiosyncratic cases of Descartes, Kepler, Galileo, and other much studied giants of the so-called Scientiªc Revolution. As a result a classiªcation of types of uses is proposed. Relations between types of analogies and research ªelds are also established. In this paper we are less interested in discussing the “real nature” or “essence” or even the cognitive limitations of analogical thinking than in describing its various uses and different meanings as they changed over the course of a century.

The object of this paper is two-fold: first, to show that contrary to what seem to have become a widely accepted view among historians of biology, the famous 1953 first Nature paper of Watson and Crick on the structure of DNA was widely cited — as compared to the average paper of the time — on a continuous basis from the very year of its publication and over the period 1953–1970 and that the citations came from a wide array of (...) scientific journals. A systematic analysis of the bibliometric data thus shows that Watson's and Crick's paper did in fact have immediate and long term impact if we define "impact" in terms of comparative citations with other papers of the time. In this precise sense it did not fall into "relative oblivion" in the scientific community. The second aim of this paper is to show, using the case of the reception of the Watson—Crick and Jacob—Monod papers as concrete examples, how large scale bibliometric data can be used in a sophisticated manner to provide information about the dynamic of the scientific field as a whole instead of limiting the analysis to a few major actors and generalizing the result to the whole community without further ado.

Academic debates are so frequent and omnipresent in most disciplines, particularly the social sciences and humanities, it seems obvious that disagreements are bound to occur. The aim of this paper is to show that whereas the agent who perceives his/her contribution as being misunderstood locates the origin of the communication problem on the side of the receiver who "misinterprets" the text, the emitter is in fact also contributing to the possibility of this misunderstanding through the very manner in which his/her (...) text is written. In other words, I propose a symmetric approach to understanding misunderstandings: taking simultaneously into account the position of the reader in the scientific field and the structure of the texts of the writers. The paper thus proposes to complement the sociological analysis of controversies in a scientific field with the close reading of texts, a practice usually found in studies of argumentation, in order to explain the occurrence of misunderstandings. The debate surrounding the charge of "relativism" among sociologists of scientific knowledge provides us with a case study to analyse in detail the argumentative context of misunderstanding.

L’intensification récente des relations entre les acteurs du champ universitaire et ceux du monde industriel a amené une montée en visibilité des questions qui touchent les conflits d’intérêts. Pratiquement toujours entendue comme une catégorie intemporelle et universelle, la notion de « conflit d’intérêts » a cependant une genèse historique et des conditions sociales d’émergence. À travers plusieurs exemples canadiens et américains du vingtième siècle, cet article montre comment émergent les conflits d’intérêts dans le champ universitaire. Alors qu’aujourd’hui ces exemples seraient (...) probablement perçus et dénoncés comme des cas flagrants de conflits d’intérêts, cela ne semble pas avoir été le cas à l’époque. En fait, le « conflit d’intérêts » suppose d’abord l’existence d’intérêts en conflits, eux-mêmes portés par des agents qui ont intérêt à percevoir, et parfois même à générer, ces conflits. (shrink)

The tendency is strong to take the notion of “conflict of interests” for granted as if it had an invariant meaning and an ethical content independent of the historical context. It is doubtful however, from an historical and sociological point of view, that many of the cases now considered as instances of “conflicts of interests” would also have been conceived and perceived as such in, say, the 1930s. The idea of a “conflict of interests” presupposes that there are indeed interests (...) in conflict. Conversely, as long as there is a consensus among the different groups involved, they will not conceive and even less denounce a given practice as being an instance of a “conflict of interests”. In this article we will show that the content of the discussions over conflicts of interests has changed over time in close relation with the transformations of the research system. In other words: there are social conditions for the emergence of “conflicts of interests”. The changing meaning of the notion is assessed by analyzing the presence of the expression “conflicts of interests” in the magazine Science over the past century. Three different meanings emerge and their content has evolved in close link with the changing structure of the relations between the scientific community first with the State and then with industry. It moved from a situation external to the scientific community to a debate going on inside the scientific community generated by the growing relations between university and industries. (shrink)

This article uses the methods of citation and network analysis to map the global structure of the intellectual field and its development over time. Through the case study of Mersenne's, Oldenburg's and Darwin's correspondences, we show how looking at letters as a corpus of data can provide a global representation of the evolving conversation going on in the Republic of Letters and in intellectual and scientific fields. Aggregating general correspondences in electronic format offers a global portrait of the evolving composition (...) of the intellectual and scientific scene, its changing foci of interests and the fortune of the intellectual discussions as expressed in cited persons in the letters. Such tools help replace a purely metaphoric use of the term “network” by a visible map of the intellectual relations between people on which well defined calculations of the centrality of the positions of different actors can be made as well as their evolution over time. These techniques provide welcome additions to the tool kit of scholars in an age where the computer and the web offer new ways of mapping and mining the rich store of information contained in intellectual correspondences.
