Abstract

If we analyze the early historical evolution of the concept of eddy or vortex, it can be shown that it constitutes a mental schema and a powerful heuristic instrument in scientific thinking, with the intuitive properties of rotation and dissipation. This mental schema presents a great capacity to constitute a fruitful analogical source and to develop an analogical inference. For example, Descartes considered celestial vortexes to explain planetary motion, or Maxwell developed the electromagnetic theory via a model based on rotating vortexes. But there were more creative and detailed uses of the eddy schema which had great importance as a cooperative heuristic instrument, instead of as a mere expedient analogy. I will present two episodes to underline the activation via provocative analogy of the eddy schema, multiple roles that it can play and its heuristic adaptability: first, the eureka visualization of an eddy by Johann Bernoulli in the genesis of fluid dynamics; and second, Reynolds’s discovery of the importance of eddies to understand the dynamic and resistance of flow.
