ABSTRACT
The notion of 'turbulence' arises from a mismatch between our powers of observation and our powers of comprehension and it arises within our present context as these powers are applied to fluids in motion. ThiS characterization of turbulence alone suffices to relate turbulence to other manifestations of this same mismatch of faculties, such as are nowadays so extensively studied in theories of chaos, the theory of fractals and other current attempts to comprehend the, at first sight, incomprehensible in nature (see, for example, Gleick, 1987; Lauwerier, 1987; Lesieur, 1987; Mandelbrot, 1982; Wuensche and Lesser, 1992).
