检察官谬误 检察官谬误是有一个有很好的数学理解有时候很有用的一个很好例子。检察官谬误基本上提到凭直觉的人趋向觉得一下的事实: 一边有叫B的迹象的时候，一边假设叫A的假设是实在，很不会。所以假设A是实在也同级不会。 在以下有一个真实发生过的例子: 一个母亲有了两个孩子，而且孩子是婴儿的时候，都个婴儿死了因为一个疾病 (叫婴儿猝死综合症)。然后那个母亲被控告了因为有怀疑她谋杀了她的孩子。有一个是正人的医生。他计算如果母亲真无罪，都她的两个孩子死了因为相同的上述的疾病非常不会。然后医生断定了母亲是无罪所以也很非常不会。可是这是一个谬误。法官不幸相信了那个医生所以母亲被定罪了。一些年后，谬误被指正所以母亲被释放出狱。如果医生还是法官有了对数学一个很好的理解，他们不做了那个谬误。 The prosecutor’s fallacy The prosecutor’s fallacy is a great example for why it is sometimes useful to have a good mathematical understanding. The prosecutor’s fallacy basically refers to the fact that humans tend to intuitively think the following: Getting evidence B, assuming that an assumption A is true, is unlikely. Then it must be equally unlikely that assumption A is true. Here’s an example that really happened: A mother had two children and both of them unfortunately died because of a certain medical condition (SIDS) when they were babies. The mother was then taken to court because it was suspected that she murdered her children. There was a doctor who acted as a witness. He calculated that, assuming the mother is innocent, it is extremely unlikely that both of her children happen to die of the mentioned medical condition. The doctor concluded that it therefore must be equally unlikely that the mother is innocent. But this is a fallacy. Unfortunately, the judge believed the doctor and the mother was convicted. The mistake was pointed out years later and the mother was released from prison. If the judge or the doctor had had a good mathematical understanding, they wouldn’t have made that mistake.

我喜欢数学的原因 我真的喜欢数学。它主要原因是因为用数学的时候你能发现只用直觉不能发现的东西。对一些问题，人的直觉有帮助的。不过也有如果只用直觉不能解决很复杂的问题。这种问题的例子是工程问题。可是一个对每人有关这种问题是个人的财务。对个人的财务来说，数学常很有用的。 英文翻译: I really like math. The main reason for that is that by using math, you can see / discover important things that you wouldn't be able to see / discover by using only your intuition. For some problems, the human intuition is useful. But there are also very complicated problems that you can't really solve by using your intuition alone. Engineering problems are a good example for these kinds of problems. But a problem of this kind that probably concerns everyone is that of personal finance. For personal finance, math is often very useful.

这或者是未来的肉 人的文化从大约一万年前用农业。我们用了动物得到肉。可是科学家发现一个不用动物得到肉的办法。你可以得到一些动物的细胞。这经常不杀动物。然后你可以把细胞在培养皿种细胞。这些细胞会成为一小快的肉。用这个办法制作很大块的肉还很难。办法也很贵。可是不远的未来办法或者比较便宜多了。这个办法大概比杀动物得到肉有效率多。
