LEGO Technic Difference Engine

`Before the day of computers and pocket calculators all mathematics was done by hand. Great effort was expended to compose trigonometric and logarithmic tables for navigation, scientific investigation, and engineering purposes.

In the mid-19th century, people began to design machines to automate this error prone process. Many machines of various designs were eventually built. The most famous of these machines is the Babbage Difference Engine. [..]

Babbage’s design could evaluate 7th order polynomials to 31 digits of accuracy. I set out to build a working Difference Engine using LEGO parts which could compute 2nd or 3rd order polynomials to 3 or 4 digits.’

    Finding a good gift for a boy or girl between 10 and 15 years is not easy. I recently discovered Lego Technic and the problem was solved. These are great as gifts. They are not expensive and they are always welcomed.
