Cartogram: Electoral Vote Results 2004 

Election Results Cartogram from Electoral-Vote.com I hadn't given much thought to cartograms until I saw one on Electoral-Vote.com.

A cartogram is a map on which the area of each division is proportional to some value other than its land area. (Somewhere I've got a periodic table of the elements from my college days with a similar feature: the more common elements have much bigger boxes.) Population, directly or through the "How many electoral college votes" function, is an obvious candidate for a cartogram.

Michael T. Gastner and M. E. J. Newman of the University of Michigan have published a paper describing a computationally-efficient method for generating such maps. One example application they give is a "Mindshare" map Gastner and Newman (2004) figure 3(b), Mindshare Map in which the area of each state (or for New York City and Washington D.C., city) is proportional to the frequency of their appearance in news stories. Besides being very interesting, it looks awfully familiar: Compare with Saul Steinberg's famous New Yorker cover (popular for a while in parody posters), "A View of the World from Ninth Avenue" (The New Yorker, March 29, 1976. A View of the World from Ninth Avenue, Saul Steinberg, The New Yorker, March 29, 1976

Students suspended for being where they were supposed to be 

Boston.com / News / Odds & ends / Entire 8th grade suspended after food fight
Principal Jada Meeks suspended students who were in the cafeteria during the fight
Not for participating in the fight, but merely for being there when it happened.
"Given an opportunity first to apologize for their behavior and help with the cleanup, most of the class refused to cooperate," school spokesman Vince McGaskill said.
There is no indication that every student who was asked to help with the janitorial work took part in the food fight.

1964 Jefferson Nickel 

Why were so many Nickels struck in 1964. Even today, forty years later, I'm coming across them from time to time; a couple of decades ago they were still unusually common among circulated coins. I couldn't find anything on-web, but this site, CoinFacts.com seems to indicate that over a billion nickels were struck in 1964, compared with less than 180 million in 1963 and about 137 million in 1965.

The Tin Woodsman 

If the Tin Woodsman was made out of tin, or even of galvanized steel, why was he so prone to rusting?

Because Seven Eight Nine! 

When I was a kid the archetypical joke/riddle was "Why did the chicken cross the road?" (and "What's black and white and red all over?") When did "Why is six afraid of seven?" take over that role?
