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

Einstein’s claim that the speed of light is constant has survived more than a century of scrutiny—but scientists are still ...

Knot theory, a vibrant branch of topology, investigates the properties of knots viewed as embeddings of circles in three-dimensional space. Central to this field are knot invariants—algebraic or ...

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

The more crucial a physical law is, the more important it is to keep testing it. One of the most important laws formulated in the last century or so is Albert Einsteinэs principle of invariance, which ...

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 ...
