  …对我挺有用。你试过吗？> 考虑到大学讲座的质量 我上的大学这方面根本不是问题。比如 Daniel Goodstein 教授就把他的讲课内容做成了一套视频系列《力学宇宙》（The Mechanical Universe）。不过坦白讲，我更喜欢他在现场用黑板和粉笔讲课的样子。

  …for me. Have you tried it? > given the quality of college lectures I attended a university where that wasn't a problem. Prof Daniel Goodstein, for example, turned his lectures into a video series "The Mechanical Universe". But, frankly, I liked his in-person lectures using the blackboard and chalk better.

  …见过的。我不会给它们特殊优待。我在80年代中期上过加州理工学院的基础物理系列课程——没记错的话，我大一那年刚好赶上他们把《费曼物理学讲义》换掉，改成 Goodstein 用他的新书《The Mechanical Universe》授课。（Goodstein 就是上面给出负面评价的那两个人之一。）当时我觉得这本新教材还算不错，但费曼那本简直绝了。没记错的话，他们想搞新教材和视频的很大一部分原因…

  …seen. I wouldn't privilege them. I took Caltech's intro physics sequence in the mid-80s -- IIRC my freshman year was when they switched from the Feynman Lectures to Goodstein teaching from his new The Mechanical Universe. (Goodstein was one of the pair with the negative quote above.) I thought at the time that the new textbook wasn't bad, but that Feynman was amazing. IIRC much of why they wanted a new book and video…

  …在资本主义框架下运作的社会问题。同样，科学在封建/宗教框架下运作也有问题，比如伽利略当年的遭遇（David Goodstein 在《The Mechanical Universe》中也讨论过）。而且科学在极权主义框架下运作也会出问题，比如苏联时期的李森科主义。http://en.wikipedia.org/wiki/Lysenkoism 但关键在于，科学可能会出现重大的系统性…

  …social problems operating within a capitalistic framework. Now, science also has problems operating within a feudal/religious framework, like Galileo encountered (and David Goodstein discussed in "The Mechanical Universe"). And science has problems operating within a totalitarian framework like with Lysenkoism in the USSR. http://en.wikipedia.org/wiki/Lysenkoism But the key point is, science can have major systematic…
