当然是"硬" I don't mean difficult, necessarily. All I mean is that we use the scientific method most of the time, and we revise our hypotheses in light of new evidence.
最近,AlexK给我发了这句话,内容涉及所有方面, 化学:
反思我们因不了解我们后来发现不正确的化学而失去了学生的数量,这令人感到不安。我搜索了该报价,该报价应归因于罗伯特·韦伯(Robert L. Weber),并发现至少有五页引用了该特定报价。
阅读时,我遇到了几个反应堆。
- 那句话真的是关于化学而不是经济学吗? [回想一下关于宏观经济学家的古老笑话,他每年都会提出相同的考试问题,但是正确的答案会随着时间而变化]
- If chemists feel that way about their subject and are viewed as a 硬 science, then surely economics qualifies. We have immutable laws, too, like the law of demand (if only half the members of our profession and all the politicians understood it!).
