Parallel worlds sound like science fiction, but modern physics paints a different picture. Quantum mechanics suggests that particles don’t choose one path—they follow all possible paths, branching ...

“Dark” electrons within solid materials may help us learn more about the behaviour of high-temperature superconductors, and perhaps solve other mysteries in material science. Most of a material’s ...

The photoelectric effect, first explained in 1905, transformed our understanding of how light interacts with matter. When high-energy light hits atoms, it knocks electrons loose. This process powers ...
