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 ...

Condensed-matter physics is the study of substances in their solid state. This includes the investigation of both crystalline solids in which the atoms are positioned on a repeating three-dimensional ...

Quantum deviations Large masses such as a galaxy curve space–time and objects move along geodesics within this curvature. If space–time itself has quantum properties, then deviations arise between a ...
