Michel Van Camp and Olivier de Viron are attracted to the fluctuations in the Earth's gravitational pull.

Paul Ginsparg shares his thoughts about the future of the preprint server he created 25 years ago.

During its 25 years of existence, arXiv has exceeded every expectation in terms of growth and its impact on how science is disseminated.

Topology has journeyed from the purely mathematical arena to feature throughout physics.

Some concepts are useful but difficult to quantify, as Philip Ball illustrates with the property of hydrophobicity.

An old branch of mathematics has paved the way for discovering new phases of matter.

Topological matter can host low-energy quasiparticles, which, in a superconductor, are Majorana fermions described by a real wavefunction. The absence of complex phases provides protection for quantum computations based on topological superconductivity.

The topological state of matter depends on its dimension. Remarkably, topological properties of quasiperiodic systems are found to emerge from higher dimensions.

Optics played a key role in the discovery of geometric phase. It now joins the journey of exploring topological physics, bringing bosonic topological states that equip us with the ability to make perfect photonic devices using imperfect interfaces.
