The Chalk Market: Where Mathematicians Go to Get the Good Stuf

The moment he placed a piece of that chalk against a blackboard, felt the smooth action, and saw the crisp, thick line it produced, Eisenbud realized he’d been wrong: There’s chalk, and then there’s Hagoromo. Which is why mathematicians get so misty-eyed about Hagoromo, likely the best chalk in the world. Soon the summer school program at MSRI will begin, and math students from universities from all over the world will be exposed to many of the greatest minds in mathematics—and also, to Hagoromo chalk.
