Need I really say more? An implementation of Babbages Difference Engine, capable of evaluating 2nd and 3rd order polynomials with two or three digits of precision. Needs some video demonstrating it in operation, but wow.
Bonus links:
- Wikipedia entry on the Difference Engine
- Difference Engine in Meccano
- A nice description of the Difference Engine, with some animations
- A fictional book by Gibson and Sterling that I didn’t like…
Double bonus: my favorite Babbage quotation
On two occasions I have been asked, ‘Pray, Mr. Babbage, if you put into the machine wrong figures, will the right answers come out?’ I am not able rightly to apprehend the kind of confusion of ideas that could provoke such a question.
Triple bonus coverage: The British Museum of Science and Industry manual on setting up their Difference Engine to do real calculations.
