Ergophobia a hospital in New Jersey as early as in the 1860s. Ergophobia is a corollary of Occupational Burnout, which is thought to be the result of long-term unresolvable job stress. The term “burnout” did not come to be used with regularity until the 1970s in the United States. Freudenberger, for example, used it to describe the phenomenon of physical and emotional exhaustion with associated negative attitudes arising from intense interactions when working with people. Later studies on ergophobia and occupational burnout build upon the existing conception of Freudenberger’s research and found the phenomenon was quite common in a variety of
Proof that e is irrational between 2 and 3: We then analyze a blown-up difference "x" of the series representing "e" and its strictly smaller partial sum, which approximates the limiting value "e". By choosing the magnifying factor to be the factorial of "b", the fraction ⁄ and the partial sum are turned into integers, hence "x" must be a positive integer. However, the fast convergence of the series representation implies that the magnified approximation error "x" is still strictly smaller than 1. From this contradiction we deduce that "e" is irrational. Suppose that "e" is a rational number. Then there exist positive integers "a"
