Oh, I loved that book!<br /><br />It is quite possible that Asimov did influence Dr Who; a lot of the writers were literature buffs, including science fiction literature. You can see a great many stories incorporating elements from all sorts of classics, although they're really never hommages or parodies or interpretations of those classics; just stories that incorporate some of the same elements.<br /><br />I think the Dr Who serial that most reminds me of Asimov is "The Robots of Death". Set on a Sandminer operated by an army beautiful robots governed by a small human crew, it's a classic closed-door whodunit. Somebody is killing the crew, one by one. What's worse, it might be a robot doing it, and this society has become completely dependent on robots, trusting in their programmed inability to harm humans.<br /><br />I don't want to give too much of a spoiler for it, but it becomes apparent that one of the crew isn't who he claims to be. Taren Capel, a notorious pro-robot terrorist, has substituted himself for one of the crew. Unfortunately, nobody knows what he looks like, so he could be any of the men. Taren Capel hates humans with a passion. He was raised entirely by robots and considers them his brothers, superior to humans. That reminded me a lot of the people in the third of the books about R. Daneel Olivaw and Lije Bailey. I don't recall the name of the planet (Aurora, possibly), but the people there lived entirely surrounded by robots, almost never seeing another human being except on videoconference. <div class="Discussion_UserSignature"> <p> </p><p><font color="#666699"><em>"People assume that time is a strict progression of cause to effect, but actually from a non-linear, non-subjective viewpoint it's more like a big ball of wibbly wobbly . . . timey wimey . . . stuff."</em> -- The Tenth Doctor, "Blink"</font></p> </div>
