PERSPECTIVES

”[wavelets] do not constitute a theory but rather a new scientific tool. Indeed, they have never been used to explain anything. [. . . ] they play nearly the same role as the pair of glasses I use to read the "Apologie de Raimond Sebond."
These glasses, now required by my age, should not be condemned if I do not understand
Montaigne’s thoughts, or glorified if I admire
them. Likewise with wavelets whose modest, but essential, role is to help us to better study, at different scales, complex phenomena.” Yves Meyer, 1990
