Donald asks, “How do you like that for mathematics?” Because rectangular billiard tables have four walls meeting at right angles, billiard trajectories like Donald’s are predictable and well ...

“There is a surprising interaction between algebraic geometry, the pure mathematics of moduli spaces, and the dynamics of billiards, that goes both ways,” said McMullen. If you’re interested in ...

Such investigations are difficult. The reason for this is that the construction of an ideal pool is linked to one of the most complex problems in mathematics: the Navier-Stokes equations.

Among other things, she studies billiards. But now, in a move very characteristic of modern mathematics, it gets kind of meta: She considers not just one billiard table, but the universe of all ...

Not on Alex Bellos’ billiard table. It has no corner pockets—indeed, it has no corners whatsoever. Bellos, a British journalist who covers sports and mathematics, combined his two obsessions ...

Math is tuned toward these special canonical ... Sure, that was my experience with the outer billiards problem. At first, the motion produced by outer billiards on a kite seemed totally noisy ...
