It seems like the author assumes that the page is accessed from his youtube channel, but as someone who just landed on the webpage with no awareness of his channel, some synopsis of the book would be nice.
The book cover has a very quick summary in the form of cartoons, but the table of contents (pp 3–4/160) has a list of what it covers, the preface (pp. 5–7/160) explains the motivations and has a little more color on what it colors, and the first chapter (pp. 9–42/160) has a really good overview of control theory including cartoons and a dialog with Ctesibios.
