"...a market economy is essentially a genetic algorithm for solving resource allocation problems..."

| Monopole Mining | ||
| Looking for natural sources of monopoles. |
Good work for belters - if you can find them.
| Nick Sohl was coming home.
...He had gone mining in Saturn's rings, with a singleship around him and a shovel in his hand (for the magnets used to pull monopoles from asteroidal iron did look remarkably like shovels)... A century ago monopoles had been mere theory and conflicting theory at that. Magnetic theory said that a north magnetic pole could not exist apart from a south magnetic pole, and vice-versa. Quantum theory implied that they might exist independently. The first permanent settlements had been blooming among the biggest Belt asteroids when an exploring team found monopoles scattered through the nickel-iron core of an asteroid. Today they were not theory, but a thriving Belt industry. A magnetic field generated by monopoles acts in an inverse linear relationship rather than an inverse-square. In practical terms, a monopole-based motor or instrument will reach much further. Monopoles were valuable where weight was a factor, and in the Belt weight was always a factor. But monopole mining was still a one man operation. Nick's luck had been poor. Saturn's rings were not a good region for monopoles anyway; too much ice, too little metal. The electromagnetic field around his cargo box probably held no more than two full shovelfuls of north magnetic pole. Not much of a catch for a couple weeks backbreaking labor... but still worth good money at Ceres. |

As Niven points out, the idea that a magnetic monopole, a particle that is a magnet with only one pole, actually exists has been around since at least the early 1930's, when Paul Dirac showed that magnetic monopoles were consistent with Maxwell's equations if electric charges are quantized, which is what is observed.
