为什么现代经济物理研究总是忽视简单性(Bertrand M. Roehner,2010),而这种对简单性的偏好以及分析方法的采用,在历史上极大的促进了物理和化学的发展,这样是做事极其危险的,在某种程度上是经济和经济物理越走越远的原因之一。
Through this example we wish to point out that if we give up trying to decompose complicated phenomena into simpler sub-modules we lose much of our ability to get a real insight. An even more serious consequence is that the models of complicated
phenomena can no longer serve as basic bricks. Such complex models are just too specific to be transposed elsewhere.
So we lose the ability to build science as a modular structure which grows in a cumulative way.
为什么直接研究复杂,因为有计算机可以处理复杂,故不需要研究简单?现在对复杂性的偏好,已经使得原本可以简单化的问题,还是采取复杂的处理方式,杀鸡用牛刀不说,更重要其影响学科基础的构建。并且对于复杂性的研究对象,只能适合那些不能分解的现象,但是不是万物都能分解,这是哲学和数学上的问题。
In short, even though computers are fantastic tools in many fields (e.g. engineering or data processing) they lead physicists
to neglect the vital task of simplifying the phenomena that they wish to understand. Sadly, the prevailing impression is that
this new soft matter physics neglected or threw away the requirement of simplicity which for centuries had been
an essential beacon in physical research. We will explain why.Before we begin this review a word of caution is in order.
经济物理要在经济学中寻找社会逻辑这个维度,如冯诺依曼(John von Neumann )提倡社会经济学中要运用数学,但这种数学并不一定和以前的数学相同。同时要考察在社会经济层次上所涌现的新法则。
Obviously, in the limits of a fairly short paper it was impossible to do justice to the many books and articles which contributed
to the growth of econophysics. Most of the citations will serve to illustrate specific events, attempts, trends or ideas that
I wish to explain. This is a fairly personal account. I did not try to give an objective narrative and apologize in advance to
all the econophysicists whose work, however important, was not explicitly mentioned.
寻找两学科之间的关系,是学科的发展趋势,这是肯定的。而经济物理学要从演化的角度研究,寻找事件在现象和法则上的统一,才有出路,否则无法寻找到两个学科共同的理论基础。总之,我提倡对经济物理的研究,应该考虑社会系统的简单性(自然性)这个维度,同时用类似适合社会经济系统的非定量数学(社会性)之类的工具。
