The Wall Street Journal  Jan. 24 on a Duke University professor —

"Dr. Daubechies is best known for her work on mathematical structures
called wavelets; her discoveries have been so influential, in fact, that
these are referred to in the field as Daubechies wavelets. She describes
them as 'mathematical building blocks' that can be used to extract the 
essential elements of images or signals without losing their quality—
in effect, a new universal language for scientists and researchers."
