Precise time underpins critical infrastructure in modern society, including telecommunications, computer networks, electrical power grids and broadcasting. At present, Global Navigation Satellite Systems (GNSS) provide the timing signals that are used by these applications; however, time signals delivered over fibre links can offer higher performance. The high accuracy time transfer achievable by fibre

Russian science icon, Pyotr Lebedev, is well known for first proving the existence of light pressure by measuring its action on both solids and gases. His experiments are discussed here as well as comparison with later, independent light-pressure measurements in solids by Nichols and Hull and European scientists. These light pressure experiments were the first steps of Lebedev's programme in unravelling

ABSTRACT Gravitational-wave astronomy started in earnest in 2015 with the first observation of waves from a binary black hole merger by NSF's LIGO detectors. Since that time, the signals from many colliding compact objects have been observed with LIGO and Virgo, giving insights into the demographics of stellar black holes, the nature of neutron stars and the products of their coalescence. Detailed

The transfer of optical momentum can exert miniscule but important forces on biological specimens. This area of optical manipulation has been thriving for over 50 years. Its importance was recognised by the award of half of the Nobel Prize in Physics in 2018 to Arthur Ashkin for the use of a single focused light beam for manipulation, namely optical tweezers. This article reviews the basic physics

Inertial Confinement Fusion (ICF) is a subject that has been studied for decades, because of its potential for clean energy generation. Although thermonuclear fusion has been achieved, the energy out has always been considerably less than the energy in, so high energy gain with a burning thermonuclear plasma is still some way off. A multitude of new science has come from the ICF programme that is relevant

Despite the economic importance of temperature measurement and 300 years of scientific research into thermal phenomena, temperature remains one of the least understood and most difficult to measure of all physical quantities. Indeed, our current ability to measure temperature in accordance with thermodynamics fails to meet our needs. This review paints a broad overview of temperature measurement, with

ABSTRACT The dynamics of nonlinear systems has emerged as an active interdisciplinary research field at the interface of biology, chemistry, mathematics, physics and engineering. This article introduces the discipline with emphasis on driven nonlinear systems. It examines the concepts from beginner's level while also highlighting some advanced topics and current research likely to lead to further advances

Quantum mechanics is one of our most successful physical theories; its predictions agree with experimental observations to an extremely high accuracy. However, the bare formalism of quantum theory does not provide straightforward answers to seemingly simple questions: for example, how should one model systems that include agents who are themselves using quantum theory? These foundational questions
