过渡金属（TM）化合物是一类具有非常不同性质的材料。其中有绝缘体、金属和具有绝缘体-金属转变的系统，大多数磁性系统是TM化合物，其中也有（高Tc）超导体。它们非常丰富的性质在很大程度上取决于不同自由度的强烈相互作用：电荷，自旋，轨道和晶格。轨道效应在这些系统中起着非常重要的作用，而且不仅仅是在这些系统中！古迪纳夫在近70年前就开始了对这一领域的研究，取得了许多重要成果。在这篇简短的评论中，我讨论了轨道物理的基础知识，并总结了在这个大领域的主要成就，其中古迪纳夫发挥了关键作用，现在被广泛用于解释TM化合物的许多性质。在正文的主要部分，我讨论了轨道物理学的新发展和观点，这仍然是一个非常活跃的研究领域，不断产生新的惊喜。
Transition metal (TM) compounds present a very big class of materials with quite diverse properties. There are insulators, metals, and systems with insulator-metal transitions among them, most magnetic systems are TM compounds, and there are also (high-Tc) superconductors among them. Their very rich properties are largely determined by the strong interplay of different degrees of freedom: charge, spin, orbital, and lattice. Orbital effects play a very important role in these systems, and not only in them! The study of this field, initiated by Goodenough almost 70 years ago, turned out to be very fruitful and produced a lot of important results. In this short review, I discuss the basics of orbital physics and summarize the main achievements in this big field, in which Goodenough played a pivotal role, and which are now widely used to explain many properties of TM compounds. In the main part of the text I discuss novel developments and perspectives in orbital physics, which is still a very active field of research, constantly producing new surprises.
