Fractals in Science, Engineering and Finance (Roughness and Beauty) by Benoit B. Mandelbrot.
About the lecture:
Roughness is ubiquitous and a major sensory input of Man. The first step to measure and simulate it was provided by fractal geometry. Illustrative examples will be drawn from the sciences, engineering (the internet) and (more extensively) the variation of financial prices. The beauty of fractals, an unanticipated “premium,” helps in teaching and bridges some chasms between different aspects of knowing and feeling.
Mandelbrot summaries his career as the pursuit of a theory of roughness.
Discusses the use of the eye as well as the ear in discovery (which I would call identification) of phenomena.
Have you listened to one of your subject identifications lately?
Are subject identifications rough? Or are they the smoothing of roughness?
Do your subjects have self-similarity?
Definitely worth your time.
