Marangoni Carlo

Carlo Marangoni, 1840-1925. Italian physicist, professor at a Lyceum in Pavia. 

Carlo Marangoni and the Laboratory of Physics at the High School "Liceo Classico Dante" in Firenze (Italy). 

Since 1869 until 1910, during 41 years, Carlo Marangoni continuously held the Chair of Physics at the High School Liceo Classico Dante at Florence. In the course of his long permanence, Marangoni to a large extent developed the ancient laboratory of Physics of the "Liceo". 

During the 1870 s, Carlo Marangoni, who was apparently aware of Carra-dori s work but not of Thompson s, formulated a rather complete theory of surface tension driven flow (M2, M3). He noted that flow could result from surface tension variations as they are caused by differences in temperature and superficial concentration, and that, conversely, variations in temperature and concentration could be induced by an imposed surface flow. Marangoni ascribed several new rheological properties to the surface (notably surface viscosity, surface elasticity, and even surface plasticity), while remarking that perhaps some of these properties could be associated only with surface contamination. Most present-day authors ascribe the first explanation of surface tension driven flow to Marangoni, and term such flow a Maragoni effect. ...
