Leila Sloman explains how Lie groups blend the language of group theory, geometry and linear algebra to help mathematicians understand important symmetries: www.quantamagazine.org/what-are-lie...
What Are Lie Groups? | Quanta Magazine
By combining the language of groups with that of geometry and linear algebra, Marius Sophus Lie created one of math’s most powerful tools.

In quantum information theory, “magic” is a property of entangled qubits that makes their state difficult to simulate on a classical computer. “It’s an appalling word,” said the physicist Martin White. But after 20 years, there’s probably no changing it now.
