Tabular errors provided a practical stimulus. But this was not his only motive. He also saw his engines as a new technology of mathematics.

Engineering, astronomy, construction, finance, banking and insurance depended on printed tables for calculation. Ships navigating by the stars relied on printed tables to find their position at sea. The stakes were high. Capital and life were thought to be at risk.
