Scientific research is about discovering, questioning, testing, and publishing results. As more is learned, more questions arise, new data are generated, and theories refined. The science community continually evaluates the ongoing body of work. The papers linked below represent examples. In addition to peer-reviewed technical articles (denoted with a #), there are papers written for a broader, non-specialized audience (denoted with an *).

Many technical journals are ‘paywalled’ and are generally accessible through a university library at no cost. But most authors (including me) will readily supply a pdf upon email request.
