In the woven basket pattern, where the strands interlace into triangles, some electrons get stuck in place, like coins wedged in the gaps of the weave. Other electrons roam freely across the whole basket, like light filling a room. Physicists have long sought the moment when these two types of electrons start to influence each other, and now it has been found in the material CsCr6Sb6.

Two sets of swings, rocking in opposite directions, don’t tilt the platform. Yet their motion creates invisible vortices that push a ball sideways. Alternagnets behave just like that: the atomic magnetic arrows are perfectly balanced, but a hidden symmetry bends the heat flow.
