场在基本相互作用的现代表述中起着重要作用。我们介绍了场的基本运动方程，并讨论了它们最重要的解：波解与电磁辐射和量子场论框架内粒子束的描述都有关。库仑解描述了点状物体周围的场。引力场波动解的存在导致了引力波存在的预言。这些都是在今天进行的实验中寻找的;这些实验的设计是勾画出来的。
Fields play a fundamental role in the modern formulation of fundamental interactions. We introduce the basic equation of motion for fields, and discuss their most important solutions: The wave solution is relevant both for electromagnetic radiation and for the description of a beam of particles within the framework of quantum field theory. The Coulomb solution describes fields around point-like bodies. The existence of a wave solution for the gravitational field leads to the prediction of the existence of gravitational waves. These are being searched for in experiments being carried out today; the design of these experiments is sketched.
