It's Time To Build the Analytical Engine

macslocum writes "John Graham-Cumming is launching a project to finish Charles Babbage's dream and build an Analytical Engine for public display. The goal: inspire future generations of scientists to work on their own 100-year leaps."

    Reading TFA sent a very real chill down my spine. Who knows what we are overlooking everyday with all the science and engineering going on in the world? The shocking thing about this whole story is that in retrospect, his idea seems obvious and is scientifically sound, but was ignored. The real point I'm trying to make is how much CAD software and man hours will it take to simulate this - but he did it all without even a pocket calculator.

      Jacquard looms had been around for awhile and used punch cards to control how the machine operated. Likewise, changing the punch cards would allow for a different pattern to be made. However, these were by no means general purpose computers and were also not capable of preforming calculations.

      Whose designs did he build on?

      No ones. There will be ten posts listing jacquard looms, none of which do arithmetic or control flow beyond making a big ole loop.

      There will be a couple posts about theoretical ideas that were eventually implemented in IBMs unit record punch card data processing gear. It only took half a century to implement his ideas in that regard.

      Why doesn't that qualify as "building on"?

      Just that the looms didn't do any math doesn't mean they weren't a a programmable device. Surely realizing that a programmable mechanical machine can be built is one of the steps on the way of figuring out how to make a machine that can solve arbitrary problems.

      And can it be a complete coincidence that Babbage decided to use the same storage medium?

      Of course, you could use the Jacquard loom to print out Life patterns, then scan those back in and create a new set of Jacquard cards based on the next iteration of the pattern. With enough cells you could create a general purpose computer using glider guns for logic. Might be a bit slow though.

    This is much more than just building it for public display. The idea is to demonstrate that it was, indeed, a fully functional device, and to give credit where credit is due.

  3. Analytical Engine: No Definitive Design Exists by wintermute1974 · · Score: 5, Interesting

    Doron Swade who wrote "The Difference Engine" (the non-fiction book, not the steampunk fiction by Gibson and Sterling) can tell you this:
    It's not possible to create The Analytical Engine. Why? Because Babbage never stopped creating the designs. There is no one clean, complete set of designs for the Analytical Engine.

    If someone were to build it, they would first have to pick and choose from among Babbage's numerous sketches, then fill in any of the missing bits. It's not a true, 100% authentic, Babbage design, unlike the simpler Difference Engine, which had a clean set of engineering drawings for its creation.

    Yes, that's why the first step is "Figure out what the Analytical Engine is". The idea is that they would look over old drawings, use them where they make sense, and fill in the missing bits with whatever would have been available at the time. It would be *an* Analytical Engine rather than *the* Analytical Engine.

    Yes just the requirement for simulating it and debugging it says to me that Babbage didn't finish his machine. It smacks of when Bell and Curtis "debugged" Langley's aerodrome to show that he really "invented" the airplane first.
    As it is Babbage is known as the father of Computers which he does deserve. Just the fact that he dreamed up this massive machine when he did shows what a great mind he had.
    Now building one is a great idea. Shouldn't be too hard to simulate with modern cad and then use rapid prototyping to make the parts.

  8. Re:Question: If we had such a computer, or artific by melchoir55 · · Score: 3, Insightful

    There is an entire scientific discipline (cognitive science) devoted to the creation of an AI. It is nowhere near succeeding. Unless the US military has managed to perform its own research (and I mean including basics like underlying philosophy which isn't even settled) then it is not possible for the US military to be harboring an AI. I know this seems possible from the outside because they get so much money... but money can't really make a few closed door researchers produce something more significant than an army of thousands of researchers sharing their data (academia) unless the money is giving those closed door researchers access to requisite hardware for the science. Hardware isn't currently the problem with AI. Currently, the problem is just figuring out what the "I" in AI even means.

  9. Babbage wasn't overlooked. He blew his reputation. by Ga_101 · · Score: 5, Interesting

    There is a great difference between somebody who had a great idea, but was overlooked and somebody who blew it.

    Babbage was the latter.

    When he showed people a small prototype of his difference engine, they knew exactly what kind of potential it had. The TFA even said that the government backed him. I'll stop the press and let that sink in. The British government knew at the time just what a game changer this could have been. What TFA article doesn't say is the extent to which they backed him. In the prices of the day, they invested the equivalent of a fully kitted out and manned battleship in the project. A battleship. What happened?

    Babbage squandered the money, fell out with every metal-smith in the country capable of building the difference engine and committed the ultimate crime of changing his mind and plans time and time and time again. Sure, he had a lot of plans for the Analytical engine, but he couldn't stay focused/act civilly enough to build the machine everybody wanted to begin with. After such an investment and nothing to show for it, nobody would give him the time of day, let alone commission him to build an even more complex machine with an unfinished design.

    It could be said, rather than a man who had a great idea that wasn't realised. Babbage had a great idea that he killed so badly via his own incompetence, nobody touched it for another 100 years.
