By treating Earth as a topological insulator — a state of quantum matter — physicists found a powerful explanation for the movements of the planet’s air and seas.

Not what I initially expected this article to be about, but I do love this kind of cross-cutting research that takes ideas from one field and applies them to a seemingly entirely different field. (Also makes me wish I’d been able to take a topology class at some point.)

    “why the heck does it always travel east?”

    I mean, come on. This one is pretty obvious.

    The driver injecting energy in this system is heating from the Sun. The boundary on the surface between where the heating is happening and where it isn’t is constantly moving West.

    Other than that, there may be some interesting connection between quantum topology and Kelvin waves, but I doubt it is of practical use.
