"Science Wikipedia pages aren't just for non-experts. Physicists – researchers, professors, and students – use Wikipedia daily. When I need the transition temperature for a Bose-Einstein condensate (prefactor and all), or when I want to learn about the details of an unfamiliar quantum algorithm, Wikipedia is my first stop. ... Despite [this], it is rare for professional physicists to contribute, in part because there are few, if any, professional incentives to do so. ... only a small fraction [of them] have edited even a single Wikipedia page."
