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
Irrational rotation between the additive and multiplicative notations is the group isomorphism It can be shown that is an isometry. There is a strong distinction in circle rotations that depends on whether is rational or irrational. Rational rotations are less interesting examples of dynamical systems because if formula_4 and formula_5, then formula_6 when formula_7. It can also be shown that formula_8 when formula_9. Irrational rotations form a fundamental example in the theory of dynamical systems. According to the Denjoy theorem, every orientation-preserving -diffeomorphism of the circle with an irrational rotation number is topologically conjugate to . An irrational rotation is a measure-preserving
