Abstract
Physicists are still searching for a convincing theory of high-temperature superconductivity. But at least the nature of the puzzle is becoming clearer. Mark Buchanan weighs the odds of a breakthrough in understanding.
We can blame Georg Bednorz and Alex Müller. Fifteen years ago, physicists thought they understood superconductivity — the tendency of some materials to conduct current with zero resistance at temperatures of around 10 to 20 kelvin.
