Well, thank you for that info, I'll definitely check both books out. Incidentally, I've nothing against popular accounts so long as they're not trivial or trite, I look forward to reading Becker. Moreover, I've often found that well written popular accounts not only tackle the subject matter from a different perspective to textbooks but also they can provide useful information that's not commonly available elsewhere. On several occasions I've had eureka moments reading such books long after I'd finished with the textbooks. Here, Roger Penrose's The Emperor's New Mind comes to mind. Also, I've ever so briefly checked the web link, I see there's hours of material there.
