There’s an adage coined by [Ian Betteridge] that any headline ending in a question mark can be answered by the word “No”.

Knot theory, a branch of topology, examines the intricate properties of closed curves embedded in three-dimensional space. At its core is the study of knot invariants—quantitative measures that remain ...

Symmetry and invariance lie at the heart of modern physical theories, serving as guiding principles in our understanding of the natural world. These ideas are central to elucidating conservation laws ...

Topological phases are at the heart of many advances in photonics and materials science. In a recent eLight paper, ...

Einstein’s claim that the speed of light is constant has survived more than a century of scrutiny—but scientists are still daring to test it. Some theories of quantum gravity suggest light might ...
