Fear of commitment Fear of commitment In self-help literature, fear of commitment is the avoidance of long-term partnership or marriage. The concept is often much more pervasive, affecting school, work, and home life as well. The term "commitmentphobia" was coined in the popular self-help book "Men Who Can't Love" in 1987. Following criticism of the perceived sexist idea that only men were commitmentphobic, the authors provided a more gender balanced model of commitmentphobia in a later work, " He's Scared, She's Scared" (1995). When aversion to marriage involves fear it's called gamophobia. A hatred of marriage is called "misogamy". Besides the common criticisms
Irrational rotation Irrational rotation In the mathematical theory of dynamical systems, an irrational rotation is a map where "θ" is an irrational number. Under the identification of a circle with R/Z, or with the interval [0, 1] with the boundary points glued together, this map becomes a rotation of a circle by a proportion "θ" of a full revolution (i.e., an angle of 2"πθ" radians). Since "θ" is irrational, the rotation has infinite order in the circle group and the map "T" has no periodic orbits. Alternatively, we can use multiplicative notation for an irrational rotation by introducing the map The relationship
