Am I correct in stating that the study of topology is purely theoretical?



To clarify, the real world is discrete or quantized (ie; digital) whether we are discussing atoms, quarks, or strings, etc; but topology seems to depend upon everything being continuous or analog.



For example, if I draw a one inch line and a two inch line on a chalkboard, there is a topological mapping of every point on the one inch line to the two inch line, but in actual fact there are twice as many particles of chalk (or atoms, etc.) on the two inch line as there are on the one inch line. What real world value then does the study of topology serve?



Recommendations for books or publications that answer this fundamental question are welcome.

    Regardless of the true nature of reality, mathematical models are useful for describing reality. Whenever you use mathematics to talk about something in the real world, the most important thing to remember is that you're using a model, and that model will have limitations. The game is to balance these limitations against the ability of the model to make calculations and predictions. Continuous models have proven incredibly useful for making calculations (see: calculus).

I would invite you to read Robert Ghrist's Elementary Applied Topology or check out Adams & Franzosa's Introduction to Topology: Pure and Applied to get a taste of some of the numerous applications of topology in the real world, regardless of whether the mathematical models involved match reality perfectly at all scales.

    You have asked a philosophical question, not a mathematical one.



    If by "purely theoretical" you mean something like "useless in the real world" then the answer is no. Topology has contributed significantly to our understanding of differential equations, which model many useful real world phenomena. In quantum mechanics, resolving the puzzling "wave particle duality" depends on seeing how the appropriate mathematical model can be treated with the mathematics of continuous systems. Without that kind of analysis we couldn't understand transistors and build computers.
    String theory (which has not yet been useful in the real world) relies on lots of topological ideas - in particular, on the study of Calabi-Yau manifolds.



    When you say




    the real world is discrete or quantized




    you are on shaky philosophical ground. We live in the real world, but we don't know what it "is". All we have in physics are mathematical models we use to make predictions about how it behaves. At the present time the best mathematical models for its small scale behavior are quantum mechanical, but they don't say the real world is "really made up of discrete pieces".

      And those supposedly "discrete" quantum mechanical models are actually expressed in terms of the mathematics of continuums. Perhaps it is possible to develop a truly discrete theory of quantum mechanics, but I've never heard of one.

      @PaulSinclair that's because QM is not discrete at all. It only says that certain phenomenon are discrete. Saying everything is discrete in QM is like saying everything is relative in relativity.

      @PyRulez - Those "certain phenomena" include everything we can observe. That being the case, we cannot say with complete confidence whether the continuous underpinings we have given the theory of QM are requisite, or just an artifact of our lack of imagination. So the best we can say with confidence is that our continuous models work. We cannot say that they are the only things that work.

    Topology is possible to apply, but to apply it you need to know it, which not particularly many engineers do. :)



    Same with any other higher math. You can do really cool applied abstract algebra things too, given you get guy responsible on project to thumb you up. This rarely seems to happen if they are not confident they understand it.

                @PaulSinclair that's because QM is not discrete at all. It only says that certain phenomenon are discrete. Saying everything is discrete in QM is like saying everything is relative in relativity.

                @PyRulez - Those "certain phenomena" include everything we can observe. That being the case, we cannot say with complete confidence whether the continuous underpinings we have given the theory of QM are requisite, or just an artifact of our lack of imagination. So the best we can say with confidence is that our continuous models work. We cannot say that they are the only things that work.

              You have asked a philosophical question, not a mathematical one.



              If by "purely theoretical" you mean something like "useless in the real world" then the answer is no. Topology has contributed significantly to our understanding of differential equations, which model many useful real world phenomena. In quantum mechanics, resolving the puzzling "wave particle duality" depends on seeing how the appropriate mathematical model can be treated with the mathematics of continuous systems. Without that kind of analysis we couldn't understand transistors and build computers.
              String theory (which has not yet been useful in the real world) relies on lots of topological ideas - in particular, on the study of Calabi-Yau manifolds.



              When you say




              the real world is discrete or quantized




              you are on shaky philosophical ground. We live in the real world, but we don't know what it "is". All we have in physics are mathematical models we use to make predictions about how it behaves. At the present time the best mathematical models for its small scale behavior are quantum mechanical, but they don't say the real world is "really made up of discrete pieces".

              Topology is possible to apply, but to apply it you need to know it, which not particularly many engineers do. :)



              Same with any other higher math. You can do really cool applied abstract algebra things too, given you get guy responsible on project to thumb you up. This rarely seems to happen if they are not confident they understand it.
