'Yo' as a Gender-Neutral Pronoun

Margaret Troyer, a former Baltimore-area teacher, published the first paper showing that "yo" is being used to replace "he" and "she." Troyer first noticed it while she was teaching middle-school kids in the area. "Some examples would be 'yo wearing a jacket,' " Troyer says, referring to her research. "Another example from the paper is, 'Yo threw a thumbtack at me,' which is a typical middle school example." So Troyer began to study her students. She gave them blank cartoons and asked them ...

 All Models are Wrong, but some models are useful

As the statistician George E. P. Box wrote, “All models are wrong, but some models are useful.”90 What he meant by that is that all models are simplifications of the universe, as they must necessarily be. As another mathematician said, “The best model of a cat is a cat.”91 Everything else is leaving out some sort of detail. How pertinent that detail might be will depend on exactly what problem we’re trying to solve and on how precise an answer we require. Nor are statistical models...

 Religion Influences Responses to Epidemics

The Christian tradition, set by the example of Jesus as a healer, stands out, Hughes says. Helping the sick was one way to ensure a trip to Heaven, so risking death from a disease's spread was encouraged. Other religions did not promote such extreme altruism. Islamic teachings basically disavowed the existence of contagious disease, despite some Arabic scholars thinking otherwise at the time. Thus Muslims believed there was no sense in trying to avoid sick people, and the emphasis was on cari...

 Back-of-the-Envelope Calculation

It was from Kuiper that I first got a feeling for what is called a back-of-the-envelope calculation: a possible explanation to a problem occurs to you, you pull out an old envelope, appeal to your knowledge of fundamental physics, scribble a few approximate equations on the envelope, substitute in likely numerical values, and see if your answer comes anywhere near explaining your problem. If not, you look for a different explanation. It cut through nonsense like a knife through butter.

 1973 Humanist Manifesto II - Ethics

Ethics THIRD: We affirm that moral values derive their source from human experience. Ethics is autonomous and situational needing no theological or ideological sanction. Ethics stems from human need and interest. To deny this distorts the whole basis of life. Human life has meaning because we create and develop our futures. Happiness and the creative realization of human needs and desires, individually and in shared enjoyment, are continuous themes of humanism. We strive for the good life,...
