      @miguelfonseca1104 4 года назад +13

      @@Valyssi this is a well perpetuated story among some philosophers and mathematician but misses zeno's point entirely. Zeno is proving not just merely that motion is impossible but that SPACE is inherently contradictory when taken as an independent existence. (Zeno is arguing inversely for Parmenide's own premise), explaining movement as a convergent series explains one part of the paradox which is how seemingly infinite points exist between finite distance but it DOESNT explain how for any given space, its Quanta is both discrete or continuous, observation merely assumes it to be.
      To put it another way, if for any and all space coordinates, if from any point from A to be B you have both quanta (points A and B) and Continuity (length AB), you have a contradiction. Either, A and B are substantial and length AB is composite, or the other way around. the contradiction of space is precisely to shift from one stance to the other when convenient without realizing that Space on its own cannot be both at once. Space either becomes one discreteless infinite space (Parmenides) or space becomes a construction from non-space parts (Leibniz)
      This is why all the top metaphysicians of the late 19th and 20th century had different responses. Bradley bit the bulet and deemed Space unreal and only the One (the Absolute ) exists, Alexander alsoo deemed space unreal but added that you only need to add the 2nd half, time to resolve the contradiction. Whitehead deemed that reality is fundamentally discrete but these discrete units, the actual occasions through relations have infinite capacity for summation and divisibility. (divisible but dont exist divided is Whitehead's motto).
      www.quora.com/Why-cant-mathematics-explain-Zenos-Paradox/answer/Miguel-Fonseca-15
      the sparknotes version, the idea that calculus solves Zeno's paradox by introducing the convergent series confuses a mathematical apparatus for conceptualization with the metaphysical conundrum. To say, space just happens to be both discrete and continous without problems a priori is no different than saying movement just happens because we see it.

    Our philosophy teacher once asked us this question and perfectly portrayed Zeno by staying oblivious to our down to earth reasoning. Here's my take.
    From Zeno's POV, in order to move from point A to point B you would travel an infinite amount of distances, since before reaching the first step you need to reach half of that step, and so on. BUT since the time it takes to travel also gets infinitely small, smaller increments of distance become cancelled out with how little time they require and thus, motion is possible.
    Later on, physics teaches that v = dx/dt, which is pretty much spot on

    Quantum physics actually fixes this problem. There is a smallest unit of distance possible that they could travel in the smallest unit of time possible, and eventually the distance left between Achilles and the tortoise would drop below that threshold. When that happens, during the next unit of time, Achilles would either have to stop, or immediately catch up. And since he doesn't stop, he catches up. He can only go either at least that unit of distance, or no distance.

    It's impressive that people were thinking about covergence of infinite series so long ago. An easy example is the decimal version of 1/3. If you write 0.333 that's close, but to be totally accurate you need 0.333333333 recurring, which is an infinite series. If you truncate the decimal you don't quite get to 1/3, much like Achilles never catches the tortoise if you truncate the series.

      Except that is not at all what the Planck length is. It is merely the point at which it is thought our understanding of quantum mechanics breaks down because quantum gravity becomes dominant.

    Every time that Achilles moves forward the increments get exponentially smaller but so does the times that it takes him to pass the turtle. Say he has to run 10 meters to pass the turtle and it takes him 10 seconds to do so. If you keep making the distance increments smaller you’re also making the time increments smaller and then time also doesn’t exist??? This is because space and time are relative to each other. You can’t have one without the other.

    It is interesting to note that every culture throughout history has had some variation on a Tortoise racing against a much faster opponent as part of their mythology. Like the great flood it seems almost impossible that it was not based on some event deep in humanity’s shared ancestry. Even the nomadic Glangle people of the fearsome Dyk hinterlands have a variation, where a slow moving creature with a shell on its back challenges the fastest cat in the kingdom to a race and by winning, wins the heart of the queen.

Just by looking at his conclusion, you know his argument is flawed, the same way there's no real reason to entertain the argument of someone explaining to you why bees can't fly or why the Earth is flat. Zeno says movement is impossible, and he is dead wrong.
      Besides, Mirco is actually explaining the only way Zeno's turtle example works. For the runner to never catch up, he must cut his speed at every mark. If the runner maintains his speed, it is impossible for him not to surpass the turtle (given that any amount of distance was closed between them once the runner started).

      Achilles wasn't slowing down, the increment which was being measured was decreasing.
      Let's say he was 10x faster than the tortoise, and the headstart is 10m. When he travels 10m the tortoise will travel 1m. Then when he moves 1m the tortoise moves 0.1m. Neither is slowing down or speeding up, the ratio between the speed of the two is still 10 to 1, it's just that Zeno failed to realise that 10+1+0.1+0.01+...-is a converging series, but even that knowledge will only tell us that Achilles passes the tortoise at 11.111...m, not why/how. That's what the paradox is asking about. So as Aashis said, you completely missed the point.

The situation in the story I had read went along the lines of "A hungry man is running to reach a boar. As he runs, he first reaches the halfway point to the boar, and the second time he runs, he only reaches 3/4 of the way to the boar. If each time he moves towards the boar, he only moves half the distance of his previous movement, he will never reach the boar, as the closer he gets, the further away the boar appears to become from his motion, even when he is nanometers away from the boar, the distance he has left to travel is infinite.

    Basically paradox word is coined from two latin words para and doxa which is commonly translated as beyond opinion or let's say against popular beliefs. Human mind can operate only within certain limits and it's thinking is limited to certain "dimensions" of time and space. In Greek word mind's thinking at the basest levels of it's operation was denoted as doxa - every human mind has it's opinions and all the mind can do is think within this limits, always swaying between two extremes which limit it and always changing it's opinions. The opposite words of doxa are episteme and gnosis which are not opinions but different kinds of advanced "knowledge". What Zeno was trying to say with his paradoxes is that you can not reach into "metaphysical dimensions of absolute truth which are beyond the mind" with the mind which is limited and operates in time. If you try too much you will break the mechanism of the mind and go mad. So this paradox is actually description of a fractal (tortoise shell is beautiful representation of a fractal i.pinimg.com/originals/3b/cf/18/3bcf18cabe462310f5d4e97e9e6aceb8.jpg) which is infinite and never converges and Achilles is human mind - hero with a sword (mind is a mechanism like a sword it always cuts the physical reality in half with it's minding and makes parts from the whole). Humanity is always trying with it's limited mind to limit the unlimited, because it is not aware of it. But this is not possible of course. The only possible solution is that the mind surrenders to the realitiy which is beyond it. Absolute truth is always a paradox (beyond mind), but not every paradox is truth. But Zeno was The man and his paradoxes are a little Zen koan gems :)) and not so much mathematical enigmas.

He's saying that u can forever cut the distance in half yes that's true. But when u account for speed the product and sum of all three will always arrive at a definitive number .. this theory is basically saying if I take 100 steps for every 50 u take u will never catch me and that is true. Notice in this race he never mentions a distance in which the race ends therefore the position of the turtle is the end point which at this point means no he will never catch the turtle because he is a continually at half .

    the way that I understand it is that distance is only infinite in the sense that it can be divided any number of times. However, there seems to be a difference between functional infinity and theoretical infinity. Theoretically, you can divide any space to any degree you wish however functionally the numbers become so astronomically small that there is no real effect hence the law of improbability. This is why even though every atom has a gravitational effect on every other atom you aren't being pulled into space or why we cant feel the earth's magnetic field. The values represented are so functionally small there is no tangible effect. Any thoughts? or did I completely miss the mark here?

      Zeno's paradox fails to account for time moving "forward" at a fixed pace. Achilles moves 10 meters in 10s, turtle moves 5 in 10 seconds. Achilles moves 5 meters/5 sec, turtle moves 2.5/5 seconds. Achilles 2.5m/2.5 seconds, turtle 1.25m/2.5s. Achilles 1.25m/1.25s, turtle .75m/1.25s. In this example, two objects moving in the same trajectory will never meet because we make the time intervals dependent on the space covered from velocity. If speed remains the same, the destination will be closer, if the destination is closer, the amount of time it takes the reach that destination at the same speed decreases. So if I said "give me an update every time you cover half the distance to destination x (let's say Wal-Mart) from the previous update" you'd be caught in Zeno's paradox. Eventually "halfway" would be measured in atoms.
      Zeno's faulty logic lies in improperly correlating infinite, fixed, and stable time progression to a finite, measured amount of space, whereas reality is opposite (with a destination as defined by a limited human mind causing [theoretically] infinite space to be divided into a finite sum thus reliant on still [theoretically] infinite time).
      Sorry about the long read but I wanted to make sure I covered all the bases. This is my firsy encounter with this paradox but I think this is how it goes. Hope it helps.

    ALL of existence is a paradox, so with that understanding, this makes total sense.

    It's not a paradox, it just leaves out information to make the theory work.
    Every step achilles takes crosses a minimal and maximal distance.
    For the first part, achilles takes for example 10 steps before he is where he tortoise was. He then only needs two more steps. Hots thirteenth step passes the tortoisr and then it's of to the finish.
    This paradox only works if achilles isn't taking steps but is instead sliding like a statue. But even then it still wouldn't be a paradox

      It was a paradox at the time the concept was realized. Calculus hadn't been invented yet.

    His idea makes sense, up until the halfway point becomes less than that of the distance you're traversing with each step, at which point you exceed the half way point and pass the other racer.
    So say they're moving one foot a time with a six foot head start, while you move two feet. It would, with you being a and the other being b;
    a 2, b 7
    a 4, b 8
    a 6, b 9
    a 8, b 10
    a 10, b 11
    a 12, b 12 - at this point your steps exceed theirs, and you catch up, which is the exact moment that Zeno's hypothesis fails through and you overtake them on the next step, thus proving that motion is possible.
