In 1822, The Difference Engine, as he called the gadget, was an ambitious conception.
Powered by falling weights raised by a steam engine, it could calculate tables by the
method of constant differences and record the results on metal plates.
It was a Six Digit calculator made of toothed wheels and run by a hand crank.
The method of constant differences is a simple but powerful technique for calculating
consistent numerical progressions. Table makers often used it, and the process can best be
illustrated with a task that the Difference Engine was designed to handle - the calculation
of the Cubes of all the numbers from 1 to 100,000. (Display 500 only)
