Lotka's Law and the Frequency Distribution of Scientific Productivity of Mathematicians and Mechanical Engineers.

로트카 법칙과 학술정보의 생산성 연구

In 1926, Alfred Lotka examined the frequency distribution of scientific productivity of chemists and physicists. He observed that the number of persons making n contributions is about $1/ n^2$ of those making one and the proportion of all contributions that make a single contribution is about $60\%$. Investigator studing the applicability of 'Lotka's Law' to Mathematics and to Mechanical engineers have fitted Lotka's Law and concluded that the law applied to these subject fields.
