This would make Jean Piaget very happy: CenturyLink Arena in Boise, also home to the Idaho Stampede of the NBA’s D-League, is facing a potential class-action lawsuit from four fans, alleging that the arena management company defrauded fans by offering taller-but-thinner large-size cups that hold the same 16 ounces as the shorter, wider small. “While […]

Against optimism about social science

Social science research has been getting pretty bad press recently, what with the Excel buccaneers who didn’t know how to handle data with different numbers of observations per country, and the psychologist who published dozens of papers based on fabricated data, and the Evilicious guy who wouldn’t let people review his data tapes, etc etc. […]

The New York Times Book of Mathematics

This was an good idea: take a bunch of old (and some recent) news articles on developments in mathematics and related ares from the past hundred years. Fun for the math content and historical/nostalgia value. Relive the four-color theorem, Fermat, fractals, and early computing. I have too much of a technical bent to be the […]

David Hoaglin writes: After seeing it cited, I just read your paper in Technometrics. The home radon levels provide an interesting and instructive example. I [Hoaglin] have a different take on the difficulty of interpreting the estimated coefficient of the county-level basement proportion (gamma-sub-2) on page 434. An important part of the difficulty involves “other […]

Back when 50 miles was a long way

This post is by Phil. Michael Graham Richard has posted some great maps from the 1932 Atlas of the Historical Geography of the United States; the maps show how long it took to get to various places in the U.S. from New York City in 1800, 1830, 1857, and 1930. (I wonder if the atlas […]
