请帮我分析一下这个句子的主要成分

你好！
Scientists, on the other hand, Hawking writes, know （that ）their job is never finished and that even the best theory can turn out to be wrong.
Hawking writes是整个句子的主语和谓语，Hawking是人名，可以这样认为：
Hawking writes：“Scientists, on the other hand,know that their job is never finished and that even the best theory can turn out to be wrong.”引号里的是这个句子的宾语，是Hawking说的话。
下面我们来分析这整个的宾语：其中，scientists是主语，know是谓语，that their job is never finished 和that even the best theory can turn out to be wrong是主语scientists的宾语从句。当有一个谓语动词后有两个宾语从句时，第一个that可省，所以我把that加了括号。on the other hand是插入语。

希望能对你有所帮助，有什么疑难可以给我发信息。
