Someday we might :-).    Connexions is a wonderful resource.   But at this point, we think a growing field like Exposure Science needs dedicated promotion and a focused effort to generate high-quality published materials.    There are very few books or study guides available to students of this field, especially those that are freely-available to students from across the globe regardless of income.     We hope to offer an educational product of value that fills this large gap.     In addition, many of the elements of this website are expected to be innovative in the area of science education, including the use of on-line, interactive techology, and the tight integration between exercises, software, and example data sets.
