The Gift of Fear Top 100 Self Help authors. The Gift of Fear was selected for the book, 50 Psychology Classics. By finding patterns in stories of violence and abuse, de Becker seeks to highlight the inherent predictability of violence. The book explores various settings where violence may be found—the workplace, the home, the school, dating—and describes what de Becker calls pre-incident indicators (PINS). By noticing PINS (events and behaviors that often precede violence), individuals can better predict violence before it occurs, and therefore, take the necessary precautions and actions to stay safe. "The Gift of Fear" also describes de Becker’s MOSAIC Threat Assessment
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
