All right. So jumping in to having established that, yes, particles have wave-like behavior, even though no, hey're not actually photons, we can't use that equation.
好的,我们已经承认了,粒子有波动性,虽然它们不是光子,我们不能用这个方程。
And that's really neat to think about, because photons, of course, are massless particles, they have no mass, so it's neat to think about something that has no mass, but that actually does have a momentum.
而且那真的不容易想明白,因为光子,当然是无质量的粒子,它们没有质量,所以这个真的不容易想明白,一些物体没有质量,但是它们事实上确实有动量。
Now, I'm not introducing any genetic material at all so I don't have to worry about it replicating because there's no genetic material, all I do is deliver the particles.
这样就根本不用引入任何遗传物质,所以我也不需要担心它会复制,因为根本不存在任何遗传物质了,我所要做的只不过是接种部分微粒
PROFESSOR: Yeah, that's right. So, what we have here, cathode rays we now know are negatively charged particles. And, in fact, he named these negatively charged particles. Does anyone know what he named them? No, not electrons - very good guess. He named them corpuscles.
学生:负电,教授:是的,我们现在知道,阴极射线是带负电的粒子,实际上他还给这些,带负电的粒子去了一个名字,有谁知道叫什么吗?
