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 1. For all terms with we have the upper estimate This inequality is strict for every "n" ≥ "b" + 2. Changing the index of summation to "k" = "n" – "b" and using the formula for the infinite geometric series, we obtain Since there is no integer strictly between 0 and 1, we have reached a contradiction, and so "e" must be irrational. Q.E.D. Another proof can be obtained from the previous one by noting that and this inequality is equivalent to the assertion that "bx" < 1. This is impossible, of course, since "b" and "x" are natural
