"It's momentum. I'm running like an express train. I don't know how to stop." (that's Max Renn in Videodrome. It's not a good thing to feel like Max Renn from Videodrome.)
Let me try to set some racing thoughts in order. This is a business I've been long curious about. Dr. Louis Slotin, the Jewish Canadian nuclear chemist and nuclear physicist famous for the "Demon Core" (and other things!) scented an analogy between nuclear fission and money, and that's why we have "dollars and cents" in a nuclear-criticality sense.
It seems intuitively obvious at least that money behaves somewhat like nuclear fuel. Pile up enough money in one place and boom! The money starts "growing". In reality, there's countless people working and toiling and driving "the economy", and that's why money can "grow", i.e. behave like one of Slotin's critical masses. Fissile systems are complex. Slight changes lead to massive differences in reactivity, which is why criticality accidents happen at all (usually): a system that was thought to be safe was, in fact, perturbed by some easily ignored factor. The substitution of one material for another, let's say, or a slight change in the geometry of a volume of U or Pu solution.
But it does boil down to individual fission events, on the submicroscopic scale. A fission event—an unstable nucleus fragmenting, either spontaneously or because it was struck by a neutron‚ producing smaller nuclei and more neutrons—might be seen as somewhat analogous to a financial transaction, I suppose. What happens when someone tosses money at a sketchy venture, when it's boiled down to individual terms? "Give me your money and I'll give you back more of it once the scheme pays off." Once enough cash piles up in one place to enable a certain game to be played (the fission event, if you like) then more cash goes flying in all directions out of that transaction. It's a loose analogy but maybe a useful one?
The money-chasers ignore the machinery that makes their monetary games possible. That's rather like pretending that no work went into refining the fissile materials. Now it's just...the juice, the stuff, the hot sauce. A huge amount of mining and chemical separation and refining and isotopic fractionation and all the rest of that went into producing something that can now simply be poured out and handled like it was soda pop—except it's not. Put too much of this spicy soda pop in one place and BOOM!
Money is a bit like that. Hm?
