 Nelson's research results and materials from an education project, designed by Oklahoma high school students and involving precipitate-forming reactions conducted in microgravity on board the STS-40, are the subject of a permanent educational exhibit demonstrating the scientific method, at the Oklahoma Air and Space Museum.From FY2001 to FY2004, Nelson surveyed tenured and tenure-track university faculty members of the "top 50" departments in each of 14 science and engineering disciplines (chemistry, physics, mathematics, chemical engineering, civil engineering, electrical engineering, mechanical engineering, computer science, political science, sociology, economics, biological sciences, and psychology).Data were collected about race/ethnicity, gender, and rank, and are complete populations, rather than samples, so they accurately reveal the small number or complete absence of underrepresented groups.
