A clash of two cultures
by Yan on 2月 14, 2007
自然杂志上一个小随笔:A clash of two cultures。这里的两种 cultures 指的是物理和生物学术圈的文化。从我上大学时就听人讲,学物理的与学生物的思维方式有多大区别,看来直到现在依旧是个话题。如文中所述,这种区别已经存在至少一个世纪。
In the past, biologists have been little concerned about whether their findings might achieve the status of a law. And even when findings seem to be so general as to warrant thinking of them as a law, the discovery of limits to their generality has not been seen as a problem. Think, for example, of Mendel’s laws, the central dogma or even the ‘law’ of natural selection. Exceptions to these presumed laws are no cause for alarm; nor do they send biologists back to the drawing board in search of better, exception-free laws. They are simply reminders of how complex biology is in reality.
A Dialogue on Mathematics & Physics

看到这个 A Dialogue on Mathematics & Physics,觉得很有意思。在谈话的最后,G. J. Chaitin 说:“Well, my current model of mathematics is that it’s a living organism that develops and evolves, forever. That’s a long way from the traditional Platonic view that mathematical truth is perfect, static and eternal.” 和我的观念比较一致。最后 G. J. Chaitin 甚至抛出毕加索的名言:theories are lies that help us to see the truth! 觉得这个论断恰到好处。
布兰妮改行教物理了:)

不要以为是我脑袋进水了,这是英国艾塞克斯大学一个博士生建的网站,地址是:
估计是布兰妮的超级fans,几乎每一页都会有布兰妮的照片。在其中布兰妮会言传身教讲述半导体物理,估计这种授课方法可能有助于减少翘课率,考虑学物理的男生居多。
