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 [...]
An on-again, off-again move by the Obama administration to scrap the federal gas tax in favor of a pay-per-mile fee would boost the tab to Americans as high as 250 percent, raising their current tax of 18.4 cents a gallon to as high as 46 cents, according to a new government study. –New [...]
A humanities faculty member and a math faculty member collaborate on a course about the meaning of math.
“Don’t worry;” I told them. “You can’t find this more frightening than I do.”
Sal Khan has done something remarkable in creating such a vast and varied library, and he deserves to be recognized. His commitment to making the site free is a rare and selfless act, and he deserves to be praised. Sal Khan is a good guy with a good mission. What he’s not, though, is [...]

For that matter, why don’t we require more than two years of history or social studies and foreign language? The students want it—69 [...]
A certificate of debt, found in a regional archive, attests that Mittenwalde lent Berlin 400 guilders on May 28 1562, to be repaid with six percent interest per year.
According to Radio Berlin Brandenburg (RBB), the debt would amount to 11,200 guilders today, which is roughly equivalent to 112 million euros ($136.79 million). –Reuters.com.
Interesting application of math to sports.
In analyzing teams’ shot quality, shot rates and shot percentages, Skinner found that the average NBA squad has a 4 percent probability of shooting the ball when left with 15 seconds on the shot clock in their final possession. The ideal rate is 12 percent.
Skinner didn’t offer guidelines [...]
Yesterday, my eight-year-old said, “I don’t like math, but I’m good at it.”
This is a huge improvement from the math-related tug-of-wars we’ve encountered almost daily for the past year and a half. Yesterday, she also finished a “Star Wars Math” game, where the idea is to play a Trivial Pursuits style game, spaced-out versions [...]
