Meteorologist Lewis Fry Richardson, creator of the first dynamic model for weather prediction, proposes the creation of a “forecast factory” that would employ some 64,000 human computers sitting in tiers around the circumference of a giant globe. Each calculator would be responsible for solving differential equations related to the weather in his quadrant of the earth. From a pedestal in the center of the factory, a conductor would orchestrate this symphony of equations by shining a beam of light on areas of the globe where calculation was moving too fast or falling behind.
