It Started Digital Wheels Turning
8th November 2011
The machine on the drawing boards at the Science Museum in London is the Babbage Analytical Engine, a room-size mechanical behemoth that its inventor envisioned but never built.
The project follows the successful effort by a group at the museum to replicate a far less complicated Babbage invention: the Difference Engine No. 2, a calculating machine composed of roughly 8,000 mechanical components assembled with a watchmaker’s precision. That project was completed in 1991.
The new effort — led by John Graham-Cumming, a programmer, and Doron Swade, a former curator at the museum — has already digitized Babbage’s surviving blueprints for the Analytical Engine. But the challenges of building it are daunting.
