{wiki=List_of_unsolved_problems_in_physics}

The most important ones are:
* <theory of everything>. We are certain that our base equations are wrong, but we don't know how to fix them :-)
  * <Grand Unified Theory>
  * <strong CP problem>
* full explanation of <high-temperature superconductivity>. <Superconductivity> already has a gazillion applications, and doing it in higher temperatures would add a gazillion more, and maybe this theoretical explanation would help us find new high temperature superconducting materials more effectively
* <fractional quantum Hall effect 5 2>

Other super important ones:
* <neutrino> mass measurement and explanation
