# Journalism by the Numbers (a pedagogical play in one scene) #math

(Lights up on a college journalism classroom. The professor enters, surveys the room.) Professor: Math! Students: (Shocked reaction.) Professor: Math!! Students: (Scattered cries of “No!”) Professor: MATH!!! Students: NO!!!   (Blackout.)   (40 minutes later.)   Professor: So, at the very least when you encounter numbers in your reporting, contact sources who can help you interpret those numbers critically. Seek out a variety of credible views on the provenance and…

# What Khan Academy’s Fun, Free Learning Empire Has to Do with Dystopian Social Control

Over the Christmas break, I’ve been churning through Khan Academy math drills, so that I can be a more effective homeschool parent. It’s actually kind of fun watching my score go up, and earning badges. In the way that birds who are trained to peck buttons for food think it’s fun to peck their little beaks bloody.

A musician wakes from a terrible nightmare. In his dream he finds himself in a society where music education has been made mandatory. “We are helping…

# Surprise! ‘Star Trek’ gold shirts more deadly than red shirts

Fascinating. Barsalou then goes all math geek and applies to the data the Bayes’ Theorem formula for calculating conditional probabilities. After a little mathematical shake and bake, he determines there is a 61.9 percent chance that any given casualty is wearing a red shirt. That still sounds high, but it’s not really once you consider the sheer number of redshirts running around the Starship. “Although Enterprise crew members in redshirts…
