Rolf Nelson is a Professor of Psychology and Dorothy Reed Williams Professor in the Social Sciences at Wheaton College (the one in Massachusetts, not the idiotic creation-preaching one in Illinois), and the only thing I can say is that I pity anyone who has to sit through one of his lectures, unfortunately. These are a series of lectures which I thought might be interesting in view of the topic of the next book in my The Little Rattuses™ children's picture book series, but I'm sorry to report that there was little to nothing to see here, so I moved along.
The idea was to discuss how we see things and how our brain interprets what we see, but the lectures were dry, humorless, rambling and repetitive, and it was truly tedious to listen to them. I kept skipping tracks to move on to more interesting bits, but those were sadly very few and quite far between. I know it's a big academic thing to get a book out there on whatever topic it is that you teach, but I really think it's better not to put one out rather than publish one this bad. You'll learn more from reading Wikipedia on the topic of sight and color vision, even if it's tough-going, than you will from these lectures and stay awake in the process. This was awful.
