Babbage's Difference Engine No 2 brought to life

Charles Babbage's Difference Engine No 2 is making its North American debut at the Computer History Museum in Mountain View, California.

A forward-thinking mathematician and engineer, Babbage designed the Difference Engine in 1847. His intent was to create an automated computing machine but he was never able to turn his vision into reality.

Over 150 years later, an impassioned Babbage expert and wealthy financier have teamed up to build Babbage's dream via a new exhibit running through next April.
