电影《Margin Call》,以及关于金融的几本书
前一阵子蒙Luckyjim推荐电影《Margin Call》,找来看过,觉得非常不错,可以拿来
骗包子。跟奥斯卡的联系嘛,可以说有以下几项:
首先,演员之一的Kevin Spacy,可是两届奥斯卡得主,应该是可以跟奥斯卡挂上钩;
其次,这个电影的题材,关于华尔街,自然会想到奥利弗•斯通的1987年的经典
《华尔街》,当然也是奥斯卡片,所以拿来骗包子算是名正言顺,云云……
当然,我喜欢这个电影的原因之一是喜欢这个电影的题材,华尔街和金融。我原先对于
这个题材并不感兴趣,就算是看过了斯通的《华尔街》以后,也没有感兴趣起来,原来
在中国学理工的时候总是对于金融很不屑。真正对于这个题材开始感兴趣,还是在读过
一些书以后,小说和non-fiction都有,其中,对我影响最大的,应该有以下几部:
《Cryptonomicon》,Neal Stephenson的近千页的砖头小说,从二战中的密码破译,到
后来的互联网络的电子货币,战争,黑客,太平洋战争,欧洲战场。加密是其中的主题

这种纯粹的毒理试验现在是不可能批准的
大部分的所谓的human data都是类似于epidemeolocial 的统计分析,而不是真正的
trial 做出来的
FDA/EMEA/SFDA等regulatory agency 评估一个trial的最最重要的因素是risk/
benefit ratio, 其中safety重要性又是在efficacy之上
所以,单独的以发现toxicity为endpoint的trial不可能被批准的

However, in your previous comments, you said:
"Anything can be toxic in high enough concentration, and anything can be
harmless at low enough concentration. From harmless to fatal, you pass
through "irritation" first."
