Research in theoretical physics will include (1) analyses of elementary particle and other physical systems using the "lattice" approximation, in which the continuum of space is replaced by a discrete lattice of points, (2) studies of chaotic behavior, and (3) analyses of physical systems whose descriptive equations can actually be solved exactly. The lattice approach enables one to study situations in which, for example, the strong nuclear force is important and cannot be treated as a small perturbation. Chaotic behavior is widespread in nature and little understood. Study of systems whose equations can be solved exactly give one insight into physical systems generally. Thus, all of these studies are important.

理论物理学的研究将包括（1）使用“格子”近似分析基本粒子和其他物理系统，其中空间的连续体被离散的点格所取代，（2）混沌行为的研究，以及（3）对其描述方程实际上可以精确求解的物理系统的分析。 晶格方法使人们能够研究强核力很重要且不能被视为小扰动的情况。 混乱行为在自然界中普遍存在，但人们却知之甚少。 对方程可精确求解的系统的研究可以使人们对物理系统有一般性的了解。 因此，所有这些研究都很重要。
