The World's Oldest Computer May Have Predicted the Future (gizmodo.com) 143

Gizmodo reports: Discovered in an ancient shipwreck near Crete in 1901, the freakishly advanced Antikythera Mechanism has been called the world's first computer. A decades-long investigation into the 2,000 year-old-device is shedding new light onto this mysterious device... It wasn't programmable in the modern sense, but it's considered the world's first analog computer.
schwit1 shares a report from the Associated Press:: For over a century since its discovery in an ancient shipwreck, the exact function of the Antikythera Mechanism -- named after the southern Greek island off which it was found -- was a tantalizing puzzle.... After more than a decade's efforts using cutting-edge scanning equipment, an international team of scientists has now read about 3,500 characters of explanatory text -- a quarter of the original -- in the innards of the 2,100-year-old remains. They say it was a kind of philosopher's guide to the galaxy, and perhaps the world's oldest mechanical computer.

    • Without such a mechanism, astrological calculations were done by intelligent, educated people, white-collar workers so to speak. If machines like this took over this kind of work, such artificial intelligence would have probably destroyed the economy.

          It was feared that if machines did the math, we'd all become "dumber", unable to do math because the machines would do it. Before that, scribes lost their jobs to the printing press. We'll see indeed, just as we have been seeing for the last thousand years or so.

    It's kind of pointless to write an article about an ancient Greek text that was found if you don't report what the text actually said.
    Bonus points if you present a translation of the text, which neither article linked to actually does. (Most likely because the researchers aren't sure what the text actually says).

        It is a purpse built analog mechanical computer.

        What it is not, is a universal computer, nor is it a reprogrammable computer.

        Any universal computer can simulate any other computer, even other universal computers. A purpose built single purpose computer is only capable of performing the calculations it was designed for.

        Compare: a modern universal computer against a mechanical cash register.

        The cash register does computations; generally, it keeps a running tally of a customer's transaction, as well as a running tally of total exchanges made during the day. It cant really do other kinds of tasks. It was not made to do so.

        Likewise, the antikythera mechanism is designed to perform computatuons: logically, when the sinusoid patterns of celestial objects will result in tangencies if overlaid. It really cant do other kinds of tasks. It was not made to do so.

        A universal computer can do both tasks, and any other task a computer is capable of being built for, because it was made to do so.

        The universal computer is fairly modern. purpose built computers are a very ancient thing. Do not try to conflate the two, or claim that one isnt a computer just because it is not a universal turing machine.

              No, it is not. Computation can be used to create a simulation, but a simulation is not inherently a computation. For example, you can simulate gravity in space by using a rotating space station, but the rotation is not in any way a simulation.

                This is obvious wrong since a simulation computes the state of the system it is simulating as it simulates it.

                As to your example, it's not even remotely relevant. There's no reason that I should care that you are comparing apples and oranges. Who cares that a trait is not a simulation?

                    The rotation of a space station is not a computation.

                    Still is irrelevant. The trait isn't the computation. The rotating space station is the simulation not the rotation, and thus, it is the computation.

                      Ok, let's just end this. First, the definition of an analog computer [dictionary.com]:

                      a computer that represents data by measurable quantities, as voltages or, formerly, the rotation of gears, in order to solve a problem, rather than by expressing the data as numbers.

                      A simulation of the Solar System for the purposes of simulating some aspect of the Solar System where the physical positions of planets at some time are represented by the machine in any way is thus an analog computer.

                      More generally any simulation of the state of a system used for that purpose which generates measurable values for estimate of some aspect of the state of the system is an analog computer.

                      Finally, this device was accurate enough for its time... and for the purposes that it was used for, but in relation to what we understand about the solar system today, it was not as accurate as you seem to think it was. Among other things, it assumed that the earth was at the center of everything, which we now know to be false. Copernicus was the first person to posulate the notion that the earth revolved around the sun, and it wasn't until Gallileo that this notion started to become widely accepted as fact.

That it can convey such information at all is nothing but an artifact (albeit an intentional one) of how it is physically built, or in the case of a sundial, how it is oriented with respect to the sun after construction.

                      A mechanical orrery is exactly the same. It doesn't "compute" the position of the planets, it simply shows where they are in relation to eachother, in very much the same way as the hands on a clock convey what time of day it is.

                      This same lame argument can be applied to any other computation or computer. Computers don't actually compute, they just show symbols, combinations of voltages, etc which convey information to us. We'll just completely ignore that these displays of information are the result of computations.

                      Once again, here's the definition of an analog computer:

                      a computer that represents data by measurable quantities, as voltages or, formerly, the rotation of gears, in order to solve a problem, rather than by expressing the data as numbers.

                      First, it's worth noting that an analog clock is a classic analog computer by definition which converts some timing signal (say from a pendulum or rocking gear)

                As a real world example of simulation as computation, we have that one of the earliest demonstrations of the existence of quantum computers was a quantum system which could only be poorly approximated by a classical Turing machine.

                Since the system could trivially simulate itself in real time, it demonstrated that there were computations (here, the simulation which you keep insisting is not a computation) which could be done by quantum phenomena far faster than the classical Turing machine.

            and any actual computations to be performed from that is left up to the operator of the orrery.

            Another obvious rebuttal here comes when you consider the question of how much much "actual" computation is left after you use the orrery. For example, if the device does a "simulation" that just happens to reduce the additonal computation effort that an operator needs from O(N) to O(1), then it's a computer no matter what you think.

    No there is must have been an at least decades-old tradition of instrument-making leading up to the design and execution of the Antikythera Mechanism, stuff like armillary spheres and quadrants and such. At some point they must have made simpler instruments that maybe could use wheels coupled by friction, and from there the very notion of toothed gears (which we take for granted) could be invented.

      There was. Research the "temple wonders" that were used in ancient Greek (and later, Roman) temples.

      You will be surprised at the degree of engineering skill involved in their creation. Unlike in our modern world, ancient greek mathematics required detailed physical proofs of the predictions of the math, before it was considered true. You can see this in the reconstructed text of the archimedes palimpsest.

      It is very possible that this object was such a proof, made to present findings to nearby scholars.

      > If I told you to make a bronze wheel 140mm in diameter with 233 perfectly spaced teeth, would you know how to do it? With tools that were available in 200 BC Greece?

      Actually, the gears in question can be replicated with simple hand tools. It requires precision craftsmanship but that wasn't exactly in short supply in those days.

      The Greeks were wicked good at Math. It was basically their thing.

        Geometry and Trigonometry, yes. Algebra and Calculus, not so much.

        Of course they can. That's how 17th century European clockmakers did it. But the very first mechanical clocks didn't have fine brass gears. It took hundreds of years of clock making to get to that point.

      Marking out teeth on a circle to make a gear is trivial using just a compass and pencil. To make it easier you can mark it out on a big circle then draw those markings back to the centre so you can have 233 perfectly spaced teeth on any diameter gear.

      The teeth would then be cut out of metal sheets with a chisel like they carved stones.

        This actually makes my point. This is the obvious kind of approach that would occur to any intelligent layman. And it would work for making short two or three wheel gear trains from very large gears where relative precision is easy to attain.

        But the Mechanism is both compact and incredibly elaborate -- far, far more elaborate than a clockwork. I dabble in watch repair so I would know; a basic clock train has five gears in the going train (which transfers power from the spring) and two in the motion work (which drive the hands) for a total of 7, and everything has to be perfect or the watch doesn't run. While the Mechanism is much larger than a watch -- about the size of a mantle clock -- its gear train had at least 30 individual gears. Backlash and other imperfections from crude manufacture, when multiplied over so many gears, would certainly translate into a frozen gear train. Even individual imperfections that were invisible to the naked eye would ruin the operation.

        So they must have had a much more sophisticated gear-machining method than chiseling out bronze blanks by hand. They might have filed teeth for gears of the required precision using some kind of index wheel arrangement; that would have occurred to the Greeks of all people. But the path to success with such methods is paved with many, many failures.

        Anyone capable of constructing something like this would have to have achieved a very high practical level of mastery at gear making before they even attempted something so difficult. Even if they took up gear making with this device in mind, they'd have made many, many proof-of-concept models with much less elaborate gear trains, because the failures they encountered at smaller scales would have guided them to ultimate success that much faster. So it's pretty clear this could not possibly have been the first such device.
