Dirac《Principles of Quantum Mechanics》的问题 以前似乎在这里还是某个大学的BBS上有人说这本书后面几章不用看,因为已经辈更新的理论替代了。 我想确认是不是有这回事?如果有是书中哪几张?具体是什么理论替代了? 谢谢指教!在线等! +++++++++++ 另外(因为内力很弱发不了另一个帖,我在这回复一下那一剑的寂寞兄的帖子): 那一剑的寂寞兄您说的 Witten 的《superstring theory》是不是这本书? http://www.amazon.com/gp/product/0521357527/104-3365062-7358326?v=glance&n=283155 Love is patient and kind ;it is not jealous or conceited or proud;love is not ill-mannered or selfish or irritable;

Re: Dirac《Principles of Quantum Mechanics》的问题 I don't remember exactly what was covered in those chapters, most likely some QED stuff that he added in later editions. If that's the case, it's true that you don't have to read those chapters. There are better books on QFT than Dirac's. Dirac actually is against many of the QFT techniques. If you have time, you might want to know why such a great physicist felt unsatisfied with QFT, but his opinion on QFT is not main-stream. 宠辱不惊,看庭前花开花落 去留无意,望天空云卷云舒

Re: Dirac《Principles of Quantum Mechanics》的问题 这本书后面几章确实被替代了,是QED替代的。但是并不是不用看,而是不用去相信。 就好比我们现在看超导理论的东西,BCS理论出现之前的东西是唯象的,但是仍然值得去看看其中一些经典文献,了解前辈的一些高见。 漫漫长夜不知晓 日落云寒苦终宵 痴心未悟拈花笑 梦魂飞度同心桥
