	It was [http://en.wikipedia.org/wiki/Claude_Shannon Claude Shannon] who later (in the 20th century) connected the idea of Babbage & Boole to realize that a machine working with a binary representation of numbers would be possible to realize using flows of electricty.		It was [http://en.wikipedia.org/wiki/Claude_Shannon Claude Shannon] who later (in the 20th century) connected the idea of Babbage & Boole to realize that a machine working with a binary representation of numbers would be possible to realize using flows of electricty, and much more simply than Babbage's machine, but in principle capable of performing the same calculations.

	In [http://www.gutenberg.org/etext/15114 An Investigation of the Laws of Thought], British Mathematician [http://en.wikipedia.org/wiki/George_Boole George Boole] also worked with a notion of capturing something of the workings of human thought, though as an abstract mathematical system rather than a mechanical one. The system of algebra he developed is now called [http://www.kerryr.net/pioneers/boolean.htm Boolean Algebra].		In [http://www.gutenberg.org/etext/15114 An Investigation of the Laws of Thought], British Mathematician [http://en.wikipedia.org/wiki/George_Boole George Boole] also worked with a notion of capturing something of the workings of human thought, though as an abstract mathematical system rather than a mechanical one. The system of algebra he developed is now called [http://www.kerryr.net/pioneers/boolean.htm Boolean Algebra].

	Note that a key property of Boole's "algebra" was that, just as with a positional number system, it was possible to represent an infinite variety of equations using just a limited set of basic "building blocks" (or "primitives") -- the "and", "or", and "not" elements. In fact, it can be shown that and can be represented using "or" and "not", and similarly "or" can be represented using "and" and "not" -- so only the system can be reduced even further to just elements. This is called [[http://en.wikipedia.org/wiki/De_Morgan%27s_laws De Morgan's Law]].
