I don't think we really need to know about this at A-level. So I'll suggest that you don't worry about it for the time being. :)

However if you really need to know about it. Here are some links. But I warn you that it's quite a long theory and you'll have much reading to do.  ;)

Actually thinking about it won't hurt........but going through all of it might confuse you even more if you're not very good in that topic. ;)
