Long the exclusive domain of AI (artificial intelligence) research, statistical probability analysis got its real start during World War II, when military intelligence wanted a way to predict possible outcomes. Throughout the 1950s, the field was continued by mathematicians such as John Nash, and now this complex discipline is becoming the stuff of ordinary business applications.
I've reached the stage in life that has been called Late Adulthood (55 to 75). This means that I have younger colleagues who have taken early retirement, and older colleagues who are still working. A further complication is the fact that I'm in a field where age doesn't command respect. Indeed, a number of people believe that there is active age discrimination in IT.
