ABSTRACT
Science is not done, is not communicated, through verbal language alone. It cannot be. The ‘concepts’ of science are not solely verbal concepts, though they have verbal components. They are semiotic hybrids, simultaneously and essentially verbal, mathematical, visual-graphical, and actional-operational. The actional, conversational, and written textual genres of science are historically and presently, fundamentally and irreducibly, multimedia genres. To do science, to talk science, to read and write science it is necessary to juggle and combine in various canonical ways verbal discourse, mathematical expression, graphical-visual representation, and motor operations in the world.
