Scalar mixing and chemical reactions in turbulent shear layers and jets are examined with emphasis on experimental results of high spatial and temporal resolution. Such measurements show that the notion of distinguishing fluids that are molecularly mixed from those that are simply stirred is valid and useful. Two models that seem especially suitable for implementing mixing analyses from this viewpoint are described and speculations on possible connections with the idea of chaotic advection offered.
