Yuasa Phenomenon, named after Japanese physicist and science historian Mitsutomo Yuasa (sometimes referred to as Mintomo Yuasa), suggests that in the modern era, the world center of scientific activity (defined as producing more than 25% of the world's scientific achievements) moves from one country to another about every 80-100 years.[1][2]
This phenomenon and its study methodology are an emerging scientometrics study area.[citation needed] Indicators [further explanation needed] are pointing to China rise as a world center of scientific activity.[5] This phenomenon is also described by other names including the Bernal—Yuasa phenomenon.
