Scientists investigate new ways of helping computers to keep their cool
Physicists at Tsinghua University may have found the answer to overheating problems. Zhang Zhihao reports.
In a scene from the sitcom The Big Bang Theory, the arrogant and awkward physics prodigy Sheldon Cooper asks a class of doctoral candidates at the California Institute of Technology if they are familiar with the concept of topological insulators.
All the students raise their hands, but when Cooper sarcastically comments "Oh, don't kid yourselves!" every one of them lowers their hand in shame.
