      Does anyone else feel like DaVinci is becoming the Nostradamus of technology?

      For every event that occurs, people point to something Nostradamus said and claimed that he predicted it. Sure, what Nostradamus actually said was very vague and can be made to fit a huge number of events, as no astrologer worth his salt would be too specific for fear of losing his job.

      It also seems that for virtually every technology that comes out, DaVinci managed to invent it a long time ago. Sometimes it's obvious, but it sometimes it seems it's all about interpretation. Sure the device in his drawings could possibly do this or could possibly do that, but is it really so or are people just wanting it to be that way? It seems to be a lot of interpretation, and I've heard so much of it, I'm starting to become rather sceptical.

      Similar to this, Christian fundamentalists love to quote Bible verses to "prove" their point. Not only do Bible verses not hold any water with me, but it seems like anyone can find Bible quotes to support virtually *any* view they have. It would surprise me if there were verses from the Bible, which interpreted in the right way, would support baby sacrifice or atheism.

      It's all about taking already existing facts or words and making them say what you want them to say.

        "Well, it'd still go to Ada for the first electrical programing. da Vincci just did it in mechanicly."

        Babbage's analytical engine was entirely mechanical, and was designed well before the invention of any device providing a consistant flow of electrical energy. However it was never actually built until a hundred years after his death, as engireeing wasn't of a high enough standard in those days to build the parts he required.

        Ada Lovelace described the methods for programming the analytical engine and wrote a program for it (ie literally wrote it). da Vinci didn't actually write a program at all, he just designed a working robot.

            The strange thing was is that Babbage was likely fully aware of a fairly new invention (for the time), known as the "relay". As a mathematician (of great renown, BTW), he was also fully aware of boolean logic, as well as binary arithmetic. In theory, he could have easily based his machine on boolean logic/arithmetic using relays and electricity - but for some reason, chose not to! It wouldn't be until Herman Hollerith in the late 1800's working in America to calculate the census - using punchcard machine tabulators and electricity, to advance down this road (and much later before more work was done to hook these tabulators together into something like a programmable calculator). I find it strange that Babbage didn't take this next step - and at least marry mechanical bits with electrical bits. It wasn't that his ideas couldn't be carried out with the technology of the day - they could. It was more likely Babbage's grander plans and financial issues (along with difficulties with his draftsman/engineer - Thomas something?) that left him from taking that next step. Had he not abandoned the Difference Engine and built it (by abandoning it, and coming up with the better design for the Analytical Engine - after spending a ton of Crown money for the Difference Engine - I can understand his investors backing out) - he would have gotten money to go ahead with the Analytical Engine in full (or, had he conceived the general purpose Analytical Engine first, etc). Furthermore, if he had taken an electrical/mechanical route - he could have likely saved a lot of money in the building of the machine (less precision needed, less machining needed). Ah well - that's history for you...

    The individual parts, interestingly, are not original to da Vinci - gears, cams, and the verge-and-foliot mechanism were all familiar concepts, particularly to clockmaking, the nanotech of da Vinci's day. Indeed, as the historian Otto Mayr has noted, "clocks and automata, in short, tended to be very much the same thing"; clocks, in 16th-century dictionaries, were considered just one type of automata. But the possibility is that da Vinci married two ideas and created, in essence, a clock on wheels - turning the segmenting of time into the traversing of space - well before anyone else had thought of such a thing.

    Then this leads us to believe that the whole device (robot) itself was a translation of clocks' motion to a linear one on a larger scale. If thats the case, then instead of Da Vinci, the credibility of being the first programmers should be given to the Egyptians [wikipedia.org].

    That article sounds like a Reader's Digest reject.

    Mark Rosheim is a well-regarded designer of industrial robot arms. His "Robot Evolution" [amazon.com], is a coffee-table book for mechanical engineers. He's strong on the practical issues academics ignore, like preventing gear-tooth breakage and cable damage in factory operations. Some of his designs are quite elegant. So he's qualified to do this. The article makes him sound like a nut.

    As for automata, it wouldn't be at all surprising for DaVinci to have done entertainment automata. It was one of the few things you could sell in the court-patronage era of mechanics. Understand that in that era, science, art, and mechanism design were hobbies of the rich. This was because you can make beautiful little mechanisms out of brass with hand tools and time, but to make power machinery that does useful work, you need an industrial infrastructure. That didn't come until much later.

    The best early automata are by Jaquet-Droz, and are in a museum in Neuchatel. [isyours.com] They still work, being carefully maintained by Swiss watchmakers, and on the first Sunday of each month, they're demonstrated. The Writer writes, with pen and ink, and can be reprogrammed for different messages. The Draughtsman draws, again in pen and ink. The Musician plays the piano. They are all cam-programmmed, and date from the 1700s. Worth a trip if you're in Switzerland. The Writer is probably the best mechanical automaton ever made.
