For over a half-century, games have been test beds for new ideas in Artificial Intelligence and the resulting successes have marked significant milestones: Deep Blue defeated Kasparov in chess, and Watson defeated Jennings and Rutter on Jeopardy! However, defeating top human players is not the same as actually solving a game, and for the first time researchers have essentially solved heads-up limit hold 'em poker.

Topology, a branch of mathematics classifying geometric objects, has been exploited by physicists to predict and describe unusual quantum phases: the topological states of matter. These intriguing phases, generally accessible at very low temperature, exhibit unique conductivity properties which are particularly robust against external perturbations, suggesting promising technological applications. The great stability of topological states relies on a set of magic integers, the so-called Chern numbers, which remain immune to defects and deformations. For the first time scientists have succeeded in measuring the topological Chern number in a non-electronic system with high precision.
