I would say be careful about sticking stuff into your personal statement that you don't know much about. Because when it comes up in an interview, it will trip you up.
No harm at all in asking people here for information on this and that. But you'll gain a deeper understanding from doing your own research, either online or from a book. Ask for the reading list on that module and do some reading on it. You'll be much better prepared to discuss it in the PS and/or interview that way.
