I wrote a couple of days ago:


<The apparent unpredictableness of certain formal finite systems
was already evident to Babbage in the 1830's. He discusses in
'Passages from the life of a Philospher', how his difference
engine could be made to produce what appear to be a regular
and monotonic sequence of numbers for a very long time, but
then suddenly produce a number that was apparently unexplainable.

With a typical Victorian mindset he suggested that a similar process
might underly 'miracles'.>

The BBC documentary program 'Inventions that Changed the World',
last night had a dramatisation of this  episode from Babbage's
memoirs.
