- let's get together: the idea that the soviets might be able to send "total conversion" bombs (a type of suicide bomber capable of detonating a nuclear device) to the united states in the guise of androids indistinguishable from humans, because they are far more advanced than us, is peculiarly absurd - but that's just the point. this is a story about the paranoia that set in during the cold war, and is actually exceedingly insightful in it's projection of that conflict collapsing into mass paranoia, reduced to symbolic movements in a game theoretic stalemate, down to the climax of absurdity that set in with reagan, when the soviets found themselves unable to react to the irrational actions of a clear madman, driven by the complete absence of any sort of predictability or logic. conservatives are right when they point out that the sharp increase in military spending under reagan ended the cold war, but not for the reasons they suggest. the truth is that the soviets were convinced that reagan was on the brink of ending it all in a fit of paranoia and dementia and stepped back because they found his unpredictability to be a threat to the existence of humanity, itself. if asimov was able to see this so clearly in 1957...
- mirror image: this is a gap text in the robot series that plugs in between the naked sun and the robots of dawn and was, for a time, the last installment in that series. this is the first application of the robot laws in this text (despite the fact that the story was written in the 70s, after all of the classic robot stories), and they are applied like an axiomatic system to solve a logical problem, although it actually comes off more as a parody of sherlock holmes than anything else - which is all very typical of baley & daneel stories. there's not much depth to the story beyond that. i should, however, point out that there are actually a couple of examples of mathematicians making competing claims for the discovery of an idea, the most famous being the argument between leibniz and newton for the rightful discoverer of the calculus. another, however, is the argument between gauss and bolyai for the discovery of non-euclidean (or post-euclidean) geometry, and that might be the more direct inspiration on the story. there are countless lesser examples. we gloss over this in math class by arguing that the logic is out there in the ether and that if the ideas are in the zeitgeist then the proofs will follow naturally, something we can all demonstrate to each other by simply doing homework. but, in the case of non-euclidean geometry, it does in fact seem that gauss rather maliciously stole the idea from the young bolyai and nobody really called him on it for decades after the fact. i'm only speculating about the influence, but that's a story you can look up, if you'd like.
- the tercentenary incident: asimov is reflecting on the bicentennial by projecting forwards events into the tercentennial, in a manner not unlike orwell's 1984 (which is a description of events in 1948, as orwell saw them, and not intended to be a projection into the future, or a user manual as some have mockingly quipped). so, was gerald ford a robot? i'm not sure that's such an easy thing to dispel of, a priori.
no, really, that's the joke - that gerald ford is a robot. no shitting. certainly, asimov may be reflecting a little on the nature of then contemporary american politics, post-watergate, in his perception of the stage-managed state of affairs. but, the joke is that gerald ford is a robot, and that's really all that this is actually about.
