Unsolved Problems

You know you have a definitive set of ideas when you can have unsolved problems for years, sometimes even hundreds of years.

You can read in Digg , a first published physical prediction of string theory. High Temperature Superconductivity is a twenty five year old theoretical physics problem.

Now physicsits from Leiden University, where superconductivity was discoverd almost a hundred years ago, claim to have solved this problem.

"Although the mystery of high temperature super-conductivity isn't fully resolved, the findings do show that major problems in physics can be addressed using string theory. And this is just the start, Zaanen believes. 'AdS/CFT correspondence now explains things that colleagues who have been beavering away for ages were unable to resolve, in spite of their enormous efforts. There are a lot of things that can be done with it. We don't fully understand it yet, but I see it as a gateway to much more.' The fact that Science was keen to publish this discovery early confirms this."

Congratulations Leiden Univerrsity! Some one hundred years of continous research in one problem of physics.
