Linguistic Clue Pushes Back Origin of "World's Oldest Computer"

Calopteryx points out a piece at New Scientist which suggests that the Antikythera mechanism may be even older than previously thought; an ancient Greek word on of the device's dials suggests the device may date to the early second century BC. The article is accompanied by a great animation of its (deduced) workings, too.

    I sometimes wonder what the world would look like today if the Catholic church hadn't held back scientific research in the middle ages and killed the best and brightest minds..

    They didn't actually do that, but don't let that get in the way of your prejudice. About the worst they can reasonably be accused of is encouraging bright people to remain celibate.

    Either way, though, it wouldn't have changed much. The Catholics did not control the entire world, and there was plenty going on outside their reach -- particularly in the Islamic world, where massive progress was made in mathematics, chemistry, and astronomy.

    Funny enough, it wasn't the RCC. As much as they're dogmatic about religious things, they were (and to some degree still are) pretty lenient and progressive towards research and science. The RCC are hardly Luddites, and quite a bit of progress that was possible in medieval times was helped by Popes who wanted better artillery and more sculptures.

    The RCC was a good scapegoat for emperors, though, if they wanted a cheap and easy way to get rid of gripers. Much like a lot of "terrorist" laws are today. Heretic, witch, communist, terrorist... why do you think the times change? The terms change, their use stays the same. It's a tool for those in power to intimidate their subjects and gain support for their quest to weed out the malcontents that dare to raise their voice.

    The RCC wasn't keen on keeping literacy down. In fact, they taught it. Most charges of heresy and witchcraft against scientists were not raised by the RCC itself but rather by powerful individuals that were threatened by them. The Roman Inquisition was one of the most advanced judical systems in those times, and many people accused of heresy hoped to be subjected to the RI instead of a "worldly" court because your chance for a fair trial (as far as fairness went in those times) was heaps higher. You had the right to a defender who was educated in Roman Law, you had the right to be sheltered, in such a way that it is possible to you to prepare for your trial, the judges were not under the direct control of the Pope (actually quite often they acted against the Pope's interests) and your chance to go out free was not too bad, compared to other trials of that times. Maybe the best example on how much these Inquisition trials were aiming at finding the truth rather than a 'desired' result was the trial of Martin Luther, who, after all, challenged the RCC itself.

    The Spanish Inquisition is the one we usually think of when we think of the term "Inquisition", with fake trials and torture and predetermined verdicts. This was by no means sanctioned by the RCC and actually just a tool of the local authorities, not one of the Holy See.

  11. Is it a 'computer' ? by Richard+Kirk · · Score: 4, Interesting

    If you read the comments, there is a hot but pointless discussion on whether this device is actually a 'computer'.

    My father worked in RAE Farnbrough in the '40s and '50's. The first early 'Pilot-ACE' prototypes were developed by Manchester University and the National Physical Laboratory. Another less well known one was made for the Ministry of Defence and sent to Farnbrough for calculating things like air flow over wing profiles. The NPL director at the time seems to have had a deep distrust of computers, and the early versions were explicitly forbidden to execute conditional jumps ( IF..THEN..ELSE ). The computer would solve flow equations by shooting from the boundary conditions, and then stop. A human operator then had to press a key to instruct it to execute the jump back to the beginning of the loop to take the next iteration. I can only imagine how irritating Alan Turing must have found that - to go right to the edge of computational completeness, and then stop just short. Aaaaugh!

    Arguments about who made the first computer tend to get rabid, fast, so people often define a computer as something that can make a conditions jump based on it's previous calculations, and not just like a player piano, rewinding its roll when it has detected the end. This is a nice, clear rule - either the machine can do conditional jumps or it can't - so it tends to get invoked when things get heated. The Antikythera mechanism had no need of a conditional jump. I have no doubt that the people who made it could have designed it to do so if they had wanted to, just as Charles Babbage could have done for the Difference Engine. However, in both cases, they did not, so in both cases, according to the narrow definition that requires a computer to do a conditional jump, this is a 'calculator' and not a 'computer'.

    I suspect the Antikythera mechanism may have had immense value for calculating the tides and the safe dates for shipping. As such, you can imagine the ship's captain chucking it over the side in an emergency, like a U-Boat commander disposing of an Enigma machine, rather than let it be captured, and copied. Maybe this is why these devices have vanished so completely from known history.

      Maybe this is why these devices have vanished so completely from known history.

      What is more likely is that devices like this were never widely known because there was very little that resembled a scientific community, so there was no way to make such knowledge public. By "no way" I mean there was neither the technical means of dissemination nor the social means of rewarding the creators of such knowledge.

      Science is a public, communal activity. Until the founding of the Royal Society in the 1600's there was no way for the nascent scientific community to actualize itself in archival journals and shared results. Such "science" as there was was carried on by practitioners who swore oaths of secrecy (much of the actual text of the vaunted Hipocratic Oath is actually about not teaching anyone but the sons of physicians any trade secrets, and not stepping on the toes of any of the other medical services unions.)

      It is therefore likely that similar techniques and ideas were rediscovered and lost many times during the past few thousand years, in a wide variety of fields. And extreme example of this is knowledge of the diameter of the Earth, which the Greeks knew pretty well, but which was sufficiently debatable 1500 years later that a nutjob like Columbus could convince people that it was about half the actual figure.

      The lack of comprehensive, authoritative publications embedded in a living community of empirical investigators meant that knowledge tended to wither and die with time, resulting in relatively slow accumulation over the long term.

    Luckily, the catholic church eventually converted these peoples

          You make it sound wonderful. Yes, just like the Catholic church "converted" the natives living in the Americas. Oh, where are they today, anyway? That's right, most of them chose to die rather than be "converted". Now why would that be?

          No, it's not burning people at the stake that brought about the renaissance. Progress and science continued East of Constantinople which less than 300 years after the fall of Rome, converted to Islam. During the golden age of the Islamic Caliphate, great progress was achieved in mathematics and natural science while Europe was embroiled in petty squabbles and eternally warring fiefdoms and baronies. The catholic church actively persecuted scientists as heretics, whereas the Islamic world embraced them (with certain limitations in the field of medicine, like not allowing dissections of the human body).

          Then the Mongols invaded and destroyed the Islamic caliphate, and again a lot of progress and knowledge was lost in the world. Fortunately for Western Europe the big fish had eaten most of the little fish, and the squabbling local bosses had been forced to accept the rule of kings by then. This allowed for the organization of navies, the re-establishment of international trade and the establishment of universities - like Salamanca in Spain and Oxford and Cambridge in England. Finally Western Europe could afford to maintain scholars again. However what mostly happened is that they copied the knowledge that was coming from the East. It would be another 200 years before the Renaissance happened, and invention took off in the West.

          No, please don't give me that line about how the church promoted scholarship. The ONLY thing the church did was force monks to copy old texts, and that's how SOME of the ancient knowledge was preserved. However monks weren't allowed to pass that knowledge on to the general public, and didn't communicate much among themselves lest they be called heretics.

          It's no coincidence that the only "religious" scientist, Mendel, only had his work on genetics "discovered" 200 years AFTER HE WAS DEAD.

          I suggest you read a few history books, and you'll see what a nasty political tool the Catholic church (or any church, for that matter) is. But remember, God needs your money.

    University of Cambridge - founded by students fleeing the University of Oxford...
    University of Padua, founded 1122 by students of the University of Bologna

    in fact, here's a link for you, where you can see that really not that many universities were founded by popes - especially outside of the Italian peninsula, and most of those were founded 200+ years after the first universities because Italy was starting to lag far behind the rest of the world. The renaissance may have begun in Italy, but if you look at the names of the great scientists, most of them are German, French or English.

    I will argue that the pope's main interests in the universities was to assure that the "fourth" doctrine, theology, was taught properly, and that none of the other fields of study (law, medicine and philosophy) strayed from permitted doctrine.
