The study on topological superconductors (TSCs) is one of the hotspots in the field of condensed matter physics and has drawn great attention. Recently, Prof. Hai-Hu Wen's group from Nanjing ...

Patterning and periodic structures are very important in physics. This led to a tremendous amount of work on learning what shapes can tile an area or fill a volume. It was found that these shapes must ...

Hello, I'm Mr Firth, and together we're going to learn about lines of symmetry. Symmetry is when one side of a shape looks exactly like the other—just flipped. Lots of buildings use symmetry because ...
