Physics

Definition

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 to technological problems.

    Picoscale engineering of bonds is a powerful method to tune materials properties. Transcending nanoscience, picoscience offers the ultimate length scale to manipulate materials through subtle bond distortions between individual atoms, as this Review discusses through several examples ranging from perovskites to superconductors and to topological materials.
