But to find out whether such grandiose ideas will ever be possible-let alone how to realize them-physicists need to get a lot better at manipulating individual atoms and molecules.

暂且不管如何实现，仅是探寻这些宏伟的想法实现的可能性，物理学家就需要在操纵原子和分子方面投入更多的研究。

So that's going to be the end of the exam 1 material, and then we'll move on to exam 2 material, which is kind of exciting, because we've been talking about just individual atoms and ions up to this point, and now we can talk about molecules, so we're going to start talking about bonding.

到此为止就是第一次考试的内容，接下来我们会开始讲第二次考试的内容，这些内容令人有点兴奋，因为我们一直都只是在讨论单个的原子,和离子到目前为止，而现在我们可以讨论分子了，要开始讨论成键的问题了。
