发帖数: 789 | 1 你似乎把数学的理和阴阳五行的理混淆起来了。
为了方便讨论，我们把trivial的推理定义为不需要refer to real world，仅靠逻辑就
能保证其正确性的推理；把nontrivial的推理定义为不能仅靠逻辑而必须使用real
world的知识才能判断真假的推理。
数学在物理上的应用是trivial的，无论表面上多么复杂，都是光靠逻辑空想就能保证
其正确性的。真正nontrivial的东西是根据实验现象提出来的假设。
阴阳五行在中医上的应用则是nontrivial的。好像我提到的从水生木推导出肝病的治疗
方法的例子。你不能光靠逻辑空想，而必须使用real world的知识才能判断其真假。中
医太多这些形式化但是又nontrivial的推理了，真的可靠吗？ |

of the economy.
My argument is that we are still far from being able to draw any meaningful

发帖数: 111 | 6 在看一个作图形分析的论文,有几处没看懂
1,any scalar field can be distorted into any other scaler field
如何理解?
2,为了克服这个困难,论文中用了cut low-density region 方法:
Since the space now has holes in it-precisely because we cut then out and
threw them away-the topology of the remaining space is nontrivial and can be
studied.
我的理解:
For example, the equation x + 5y = 0 has the trivial solution (0, 0).
Nontrivial solutions include (5, –1) and (–2, 0.4). 我们扔掉的low-density
区域就是那些含有trivial solution (0, 0)的区域? 我对这个对应过程转不过弯.
