Abstract
In 1953, Enrico Fermi criticized Dyson's model by quoting Johnny von Neumann:
"With four parameters I can fit an elephant, and with five I can make him
wiggle his trunk." So far, there have been several attempts to fit an elephant
using four parameters, but as the problem has not been well-defined, the
current methods do not completely satisfy the requirements. This paper defines
the problem and presents an attempt.
1953 年，恩里科-费米（Enrico Fermi）引用约翰尼-冯-诺依曼（Johnny von Neumann）的话批评了戴森的模型："用四个参数我就能拟合一头大象，用五个参数我就能让它扭动躯干"。迄今为止，人们已经多次尝试用四个参数来拟合大象，但由于问题没有得到很好的定义，目前的方法并不能完全满足要求。本文对这一问题进行了定义，并提出了一种尝试。
