王孟源:不敢对英文媒体如此胡扯,就在中国炒作?

2017-08-09 13:19:24   北京时间

我在上一篇文章里面,批评了张首晟教授有关"天使粒子"的炒作。这并不是说张教授的物理研究,和超弦一样是个假大空的大忽悠。事实上,手性Majorana费米子在凝态物理中,以虚拟粒子的形态被发现,仍然是个重要的结果,只不过张教授对媒体的炒作太过了头。

我在那里的论点主要有三项:

1)Majorana费米子是自己的反粒子,这个特性和天使的关系太过牵强,只有商业性炒作才会为了激起欧美基督教社会里大众媒体的兴趣,而把两者强行胡扯在一起;

2)虚拟的Majorana费米子在过去五年,已经有多个凝态物理团队做出发现,张教授发现的手性Majorana费米子是一个特例,所以即使"天使粒子"名副其实,张教授所吹嘘的功劳也不全属于他的团队;

3)张教授的炒作,在专业和半专业的层次,是完全针对中国的。在受美国科普媒体以英文访问的时候,张教授就没有忘记要提起过去五年其他团队的成就,也没有向记者吹嘘他是诺贝尔奖的大热门。

公道自在人心,张教授的成就,并不像媒体宣传的那样到了该得诺奖的层级。我原本就觉得,张教授身为名校的终身教授,有很优越的研究环境,所以分心去办风险投资公司,还宣称自己会"100%地做物理,也同时100%地做风投"是既不诚实,也不负责任的态度。

结果我和其他一些专业人员对事实的揭露,还是不足以劝阻张教授。他最近又发表了一篇公关文章,其中居然发明了一个"粒子-准粒子相对性原理"。

这个论述是典型的指鹿为马、颠倒黑白的狡辩术,它的目的是把高能物理里面的真实粒子和凝态物理里面的虚拟粒子混为一谈,这当然是谬误的。张教授不但不可能在学术期刊上发表这样的高论,事实上也不敢对英文科普媒体如此胡扯,只有中文读者才有幸能看到如此惊人的结论。但是张教授的论述完全基于超弦理论,所以不但中国的凝态物理学者无法反驳,就是中国的高能物理界,也因为专注在实验和现象学上,可能绝大多数人都不知其奥妙。我在这里简单解释一下。

张教授说,在超弦理论里,粒子是超弦的激发态:当超弦不振动的时候,是真空;当超弦被激发之后,开始振动,第一个激发态是轻粒子,例如电子;更高的激发态对应着重粒子。我想问读者一个问题,你读了张教授的描述,是怎么理解"重粒子"这三个字的?高能物理里面,和电子性质完全相同,只是质量较高的,还有两个粒子,就是渺子和陶子,那么渺子就是超弦的第二激发态,陶子是超弦的第三激发态了?
