Haldane, Kosterlitz and Thouless did work at the "tip of a branch that joins the core of physics very close to the trunk"

If it weren’t for the fact that my fellow science communicators relish a challenge, I would say that the physics Nobel committee has done them no favours. The work of this year’s laureates—Duncan Haldane, John Michael Kosterlitz and David Thouless, all of them British but all now working in the USA—concerns processes called topological phase transitions, and you could spend precious column inches explaining both the adjective and compound noun here without inching much closer at all to an explanation of what they are doing in conjunction or what the subject is all about.
I am duty bound to have a crack at it. But there is, frankly, no point in doing so without first digging down to a deeper stratum. I could end up saying vague things about weird electrical behaviour and offering a probably false promise that some fancy new electronic devices might emerge from it all, and I would only thereby be colluding with the pernicious myth that the value of science lies with its applications. (I call it pernicious not so much because it is what we are often told but because funding criteria increasingly force scientists to maintain the pretense too, which is far worse.)
