Summary

[edit]
Description

Quite the perfectionist, Babbage designed this incredibly complicated 5-ton mechanical computer with 8,000 parts in 1822-1849, before the era of standard screws. It would calculate and print tables of solutions to seventh-order polynomials using only addition. Half of the parts are dedicated to the creation of book printing templates to remove all possible sources of human error in the tables, a source of great irritation to Babbage.

While Babbage never saw one built during his lifetime, <a href="https://www.flickr.com/search/?q=myhrvold&w=44124348109@N01">Nathan Myhrvold</a> commissioned the construction of this one, which is cranking away at the Computer History through the end of this year.

I took an <a href="https://www.youtube.com/watch?v=qhDMi-eLizQ" rel="nofollow">HD video</a> of the beautiful ripples of movement through the soul of the machine.
