As of 1970, we have counted 278 articles on the vulgarization of plate tectonics or on related topics, in magazines such as: Libération, Le Monde, Le Nouvel Observateur, La Recherche, Pour la Science, Sciences et Avenir, Science et Vie, Science et Vie junior, Ciel et Espace, La Revue du Palais de la Découverte, Sciences Progrès Découverte, Ça m'intéresse, Cailloux, Terre Sauvage, L'Argonaute, Télé 7 Jours, National Geographic, Géo and Time Life.

17. This treatise is interesting for a number of reasons: it was written by an international specialist in plate tectonics who made a major contribution to the formulation of the theory. The treatise was used as a reference for almost twenty years by French-speaking students, PhDs and scientists, and is still used as such despite the progress made since; it was written in the mid-seventies, at a time when plate tectonics was still considered revolutionary in spite of universal recognition.

28. 'Et rose elle a vécu ce que vivent les roses, L'espace d'un matin. . .' (The rose, it has lived the life that all roses live: the space of a morning. . .) is a very famous verse from Malherbe.
29. To go back (in time) is 'remonter (le temps)', which is also the opposite of 'to descend'.

31. Aside from the ambiguity produced by these devices, the first one can simply be misleading: plants and animals have always adapted without needing to accomplish fantastical transformations. This is simply the theory of evolution expounded by Charles Darwin in the mid-nineteenth century. Moreover, the term 'transformation' (in French, 'mutation') used in this context refers to genetic alteration (mutation génétique) which is a very common phenomenon, ultra-quick but not viable in practically all cases. The few successful alterations are found in the bacterial or plant world.
32. A participant to the evaluation groups asked: 'Where will it be possible to live if plates go on moving?'

(Paris: CEREM/URA887/Palais de la Découverte).
33. 'Plume' refers to a particular form of thermal instability within a fluid which causes hot matter to rise in the form of a 'bubble' fed by a narrow conduit. This is the physical explanation of the hot-spot phenomenon about which the author is writing.
34. Note that temperature is another physical quantity which is difficult to portray. Adjectives like burning and glowing are here used to qualify temperatures exceeding 1000 C.
35. A survey of a large number of articles written for the general public (53) came up with 149 different verbs of action (or their noun forms) used to describe the movement of plates.

41. It is known that there is an enormous amount of literature dealing with analogy and metaphor, also in the construction of the sciences. For material in French, see Canguilhem's first text published on this matter: Canguilhem, G., 1979, Etudes d'histoire et de philosophie des sciences (Paris: Vrin).

43. The isostatic principle was expounded in the mid-nineteenth century by the Britons Pratt and Airy, independently of each other. They suggest that the Earth's crust rests in equilibrium upon a less dense fluid. Airy uses the analogy of a raft made of tree-trunks floating on water.

45. However, they deal with more particular geological phenomena; the general model of plate tectonics is considered of secondary importance. In fact, the geologist writing an article today rather deals with chemical and mineralogical reactions that occur when magma rises in hot spots, or pressure and temperature variations in the accretionary prisms of island arcs, etc. His main intention is no longer to expound or explain plate tectonics theory.
46. The definition is one of the essential devices of reformulation. It is part of the great tradition of the language dictionary's encyclopaedic vocation. See Rey-Debove, J., 1988, Dictionnaire de langue et définitions scientifiques. Langages, discours & sociétés, 5, Sciences et médias (Paris: Didier-Erudition), pp. 189-204.
47. Note that the total duration of human history is minuscule compared with geological time. Man is only four million years old as far as the hominids are concerned (Australopithecus and Homo), less than 2 million years old for the Homo genus and 120 000 years old for the sub-species known as Homo sapiens sapiens (us).
48. We would like to emphasize that while writers who are professional scientists may be more sober and thorough than journalists, they do not use very different paraphrastic devices from those used by journalists.
