In MAKE Vol. 15, George Dyson, who writes the Retrospect column, looked at the mortgage meltdown.
The roots of the current financial meltdown can be found in John von Neumann’s model of general economic equilibrium, first developed in 1932. Von Neumann elucidated the behavior of an expanding, autocatalytic economy where “goods are produced not only from ‘natural factors of production,’ but ... from each other,” and he proved the coexistence of equilibrium and expansion using the saddle-point topology of convex sets. Some of his assumptions – such as that “the natural factors of production, including labour, can be expanded in unlimited quantities” and that “all income in excess of necessities of life will be reinvested” – appeared unrealistic to others at the time, less so now that Moore’s Law and the zero-cost replication of information are driving the economy of today. Other assumptions, such as an invariant financial clock cycle, are conservative under the conditions now in play.
Von Neumann, who made seminal contributions to digital computing, left a number of distinct monuments to his abbreviated career, among them his Theory of Games and Economic Behavior (with Oskar Morgenstern) and his Theory of Self-Reproducing Automata (with Arthur Burks). Synthesis between these two regimes is now advancing so quickly that no unified theory of the economics of self-reproducing systems has been able to keep up. Periodic instability should come as no surprise. We may be on the surface of a balloon. Or in the saddle of a dynamic equilibrium – we hope.
Alex Wood is an addict but won’t give up his smartphone. But he has five strategies for limiting its control over him: “I used to wake up tired. My body would ache and my head felt sore, like waking up with a hangover. Finally, I took control, like attending an AA class for addicts, I […]
Ok, it’s not just solar powered. It’s also an anti-theft, waterproof marvel that keeps my phone’s power bar from ever getting into the red.Sure the idea seems obvious now – tuck a gigantic solar powered battery pack into an exposed slot and turn the wearer into a walking energy harvester. Simple maybe, but I didn’t […]

These toy planes are outfitted with ultra-bright LEDs, so you can fly all night without losing them in the trees.Whether you are a regular-sized child, or an overgrown adult one, these light-up flyers offer […]
You know the drill. You go to the dentist and they ask you how often you floss. You lie through your teeth and say, “every day!” (Bonus points if you have some cilantro or chives stuck in your gums from lunch). You don’t want to keep up the charade any longer, but rubbing that tiny strand […]
The Raspberry Pi Foundation has done outstanding work packing a fully capable desktop computer into a package the size of a deck cards—especially one that only costs $35. But if you already have a working laptop, why should you care? Oh, how much you have to learn. Besides operating well as a compact digital media hub, […]
