Every particle in Nature has an amplitude to move backwards in time, and therefore has an anti-particle. […] I’d like to show you what this backwards-moving electron looks like to us, as we move forwards in time. […] We start at T0 with an electron moving toward a photon, which is moving in the opposite direction. All of a sudden—at T3—the photon turns into two particles, a positron and an electron. The positron doesn’t last very long: it soon runs into the electron—at T5, where they annihilate and produce a new photon. Meanwhile, the electron created earlier by the original photon continues on through space-time.
所以,电子是真的进行了时光倒流,只不过在随着时间正向流动的人眼里看来就成了正电子吗还是说这是一个假说/理解方程的角度?
you think I’m going to explain it to you so you can understand it? No, you’re not going to be able to understand it. Why, then, am I going to bother you with all this? Why are you going to sit here all this time, when you won’t be able to understand what I am going to say? It is my task to convince you not to turn away because you don’t understand it. You see, my physics students don’t understand it either. That is because I don’t understand it. Nobody does.
我好像是第一次看书的时候看 foreword preface 和 introduction 这么认真,因为我怀疑正文我都看不懂
因为我妈是数学老师兼班主任,我把这条转给她看了

Throughout much of history, prodigies were thought to be possessed; Aristotle believed that there could be no genius without madness. Paganini was accused of putting himself in the hands of the devil. The Italian criminologist Cesare Lombroso said in 1891, “Genius is a true degenerative psychosis belonging to the group of moral insanity.” Recent neuroscience demonstrates that the processes of creativity and psychosis map similarly in the brain, each contingent on a reduced number of dopamine D2 receptors in the thalamus.
因为有高智商自闭症人士的存在,我看自闭症总是有层滤镜,结果这书里直接有一章就是 prodigy(天才,神童)…感觉社会还是过于贬低疯子过于抬高天才了,智商应该只是人的属性之一…
“She made friends with Madonna,” her mother said. “I didn’t make friends with her,” Natasha protested. “She told me, ‘You classical musicians are too stuck-up. You really should think about wearing hot pants.’”
麦当娜说过这种话??
“Everyone would say, ‘You must be so proud of your daughter,’” Natalie said. “I used to say that it’s not for me to be proud, it’s Natasha who does this herself—but I learned that this is not the polite American way. So now I always say, ‘I am so proud of my daughter,’ and then maybe we can have a conversation.”
哈哈哈哈美国人,这本书里真的超多父母都在 proud of 他们的孩子。
To be a musician, the person has to have a mimetic capacity to reproduce others’ techniques. “That should not be dismissed as simply replication,” said Justin Davidson, music critic for New York magazine. “That’s how we learn to speak, to write, to express ourselves.
The question of how high IQ correlates to genius has been in debate ever since the tests were introduced. Terman followed a group of about fifteen hundred children with very high IQs; seventy years later, his critics claimed, they had accomplished no more than their socioeconomic status would have predicted. One child Terman had excluded as not bright enough, William Shockley, had coinvented the transistor and won the Nobel Prize in Physics.
我一直觉得 IQ 测试太片面了,说明不了什么…
most people embark on parenthood in optimism, and even those who soberly consider a worst-case scenario cannot adequately predict their response to such a situation until they are in it.
怎讲,这本书里的各种极端例子让我越看越乐观,感觉我也能当妈了(明明很多对这本书的好评都是:这本书看着很压抑但请坚持看下去
In Peter Singer’s definition, Imogen, Ashley, and others like them are not persons. Nonetheless, the parents I met who lived with and cared for such children often described a great deal of personhood in them. It’s impossible to establish in any given case in what measure such personhood is observed and in what measure imagined or projected.
也有听说狗的情感是人类的投射,狗的主人会想象狗在某种情景中的感受,并且用来解释狗的反应,即时狗在不同场景里的反应并没有什么不同??
He proposes that not all persons are human beings; […] In Practical Ethics he wrote, “Killing a disabled infant is not morally equivalent to killing a person. Very often it is not wrong at all.” […] Singer in effect reverses cogito, ergo sum and says that those who do not think do not exist.
啊这,“我思故我在”等于“我不在故我不思”啊,怎么能说“我不思故我不在”呢…
