For my book Brain Trust , I interviewed Keith Devlin, NPR’s “Math Guy,” a World Economic Forum fellow, and math professor at Stanford. And being a mathematician, Devlin thinks about things differently than the world at large. For example, in his very good monthly column Devlin’s Angle , he quotes the following problem, originally designed by puzzle master Gary Foshee: “I tell you that I have two children, and that (at least) one of them is a boy born on Tuesday.
Ever wonder how efficient it is to heat water?
On the mystery of a ball that fills a box, but vanishes in the vastness of higher dimensions Brian Hayes The area enclosed by a circle is π r 2 .

Higgs discovery celebrates math's power to make predictions about the real world By Tom Siegfried Web edition: July 4, 2012
Indra’s Pearls concentrates on the beauty of maths and explores the ideas of Felix Klein, who was a geometer from the 19th century. I put this on the list because, to me, it is the most beautifully visual mathematics book I have ever seen. It is about what is called Fuchsian groups and Kleinian groups.
© Alain Herzog 22.11.11 - For fifty years, mathematicians have grappled with a so-called “fixed point” theorem. An EPFL-based team has now found an elegant, one-page solution that opens up new perspectives in physics and economics. Take a map of the world.
Tallis in Wonderland Raymond Tallis pinpoints the mathematics/reality divide. Readers of this column will have had a hint of my views on the limitations of the ability of maths and physics to capture lived experience – in particular in ‘ Time, Tense and Physics: The Theory of Everything But… ’ in Issue 81.
This may be the weirdest doughnut you have ever seen, but it solves a long-standing geometrical puzzle that evaded mathematicians including Nobel laureate John Nash, who inspired the film A Beautiful Mind .
THE symbols we use to represent numbers are, mathematically speaking, arbitrary.

Can science find a better measure? Photo: Christopher Griffith; kilogram models by Jim Zivic The official US kilogram — the physical prototype against which all weights in the United States are calibrated — cannot be touched by human hands except in rare circumstances. Sealed beneath a bell jar and locked behind three heavy doors in a laboratory 60 feet under the headquarters of the National Institute of Standards and Technology 20 miles outside Washington, DC, the shiny metal cylinder is, in many ways, better protected than the president.
