计算是物理学中的第三种研究模式，它弥合了分析理论和实验室实验之间的差距(1)。实验在复杂的自然现象中寻找模式。理论将发现的模式编码成数学方程，为自然行为提供预测规律。计算机模拟在完全复杂的情况下数值求解这些方程，其中解析解由于大量的自由度、非线性或缺乏对称性而被禁止。在计算机模拟中，环境被完美地控制，极端条件可以超出实验室实验的范围。
Computing is the third mode of research in physics which bridges the gap between analytical theory and laboratory experiment (1). Experiments search for patterns in complex natural phenomena. Theories encode the discovered patterns into mathematical equations that provide predictive laws for the behavior of nature. Computer simulations solve these equations numerically in their full complexity, where analytical solutions are prohibitive due to a large number of degree of freedom, nonlinearity, or lack of symmetry. In computer simulations, environments are controlled perfectly and extreme conditions are accessible beyond the scope of laboratory experiments.
