We have been looking for a way to get an explanation system seeded for a long time, and it occurred to us that a set of annotations to my book might be one way to get it started. At first, the explanations here will be strongly tied to characters and situations in Quicksilver and so may be of only limited interest to those who have not read the book. However, with a few clicks we might move on to more general explanations. For example, Robert Hooke and Robert Boyle appear as characters in Quicksilver , and so early on we might see annotations concerning specific things that they are shown doing in the book. But later these might link to explanations of Boyle's Law .Such an explanation need not refer to Quicksilver in any way, and so it could be useful to, say, a high school student who has never heard of me or my book but who needs to understand Boyle's Law and why it is important.
