Read this: The machine was about a century ahead of its time. All the parts for his machine had to be made by hand this was a major problem for a device with thousands of parts. Eventually, the project was dissolved with the decision of the British Government to cease funding. Babbage's failure to complete the analytical engine can be chiefly attributed to difficulties not only of politics and financing, but also to his desire to develop an increasingly sophisticated computer and to move ahead faster than anyone else could follow. Nevertheless, his son, Henry Babbage, completed a simplified version of the analytical engine's computing unit (the mill) in 1888. He gave a successful demonstration of its use in computing tables in 1906.
Now answer this question, if there is an answer (If it cannot be answered, return "unanswerable"): Who created a simple version of the analytical engine's computing unit?
Henry Babbage
