Physics is the search for and application of rules that can help us understand and predict the world around us. Central to physics are ideas such as energy, mass, particles and waves. Physics attempts to both answer philosophical questions about the nature of the universe and provide solutions ...
Cavity-enhanced energy transport in molecular systems The authors discuss the physics underlying the enhancement of energy transfer and energy transport in molecular systems and identify key questions and theoretical challenges for future research.
Central to physics are ideas such as energy, mass, particles and waves. Physics attempts to both answer philosophical questions about the nature of the universe and provide solutions to technological problems.Featured Imaging a new class of magnetism Using X-ray microscopy, the properties of a ...
Because physics elucidates the simplest fundamental questions in nature on which there can be aconsensus, it is hardly surprising that it has had a profoundimpacton other fields of science, on philosophy, on the worldview of the developed world, and, of course, on technology. ...
