Fear of commitment of self-help, Harvard psychologist Deborah DePaulo has written books such as "Singleism" on the stigmatization of single people. The use of the term "fear" or "phobia" imparts an inherent linguistic bias. It recasts specific lifestyle decisions (such as bachelorhood vs. marriage, or a conscious decision to remain childfree by choice) implicitly as generalised, irrational phobias while failing to identify, describe or address an individual's specific motives. For instance, the men's rights movement, citing high divorce rates and expensive alimony and legal costs, would speak not in terms of "fear of commitment" but of "marriage strike" to reflect their position that
Proof that e is irrational Proof that e is irrational The number "e" was introduced by Jacob Bernoulli in 1683. More than half a century later, Euler, who had been a student of Jacob's younger brother Johann, proved that "e" is irrational; that is, that it cannot be expressed as the quotient of two integers. Euler wrote the first proof of the fact that "e" is irrational in 1737 (but the text was only published seven years later). He computed the representation of "e" as a simple continued fraction, which is Since this continued fraction is infinite and every rational number has a terminating continued
