It is now over 100 years since superconductivity was discovered and it took 45 years before a theory was formulated by John Bardeen, Leon Cooper, and  Robert Schrieffer (BCS). Once understood, the impact of the BCS theory has been felt far beyond  superconductivity.  High-temperature superconductivity in copper oxides, with critical temperatures as high as 138K, well above what was anticipated by the BCS, was discovered 25 years ago and remains a major unsolved physics problem to date.  

The challenge of this problem is symbolized by the complex phase diagram of the oxide materials with intertwining unusual properties that may or may not contribute to the appearance of superconductivity at such high temperatures.  None of the observed properties can be described piecewise by conventional theory, and appear to be different manifestations of the same underlying physical system, making an integrated, and cohesive understanding a necessity.
