    Intuitive explanation of parallel transport and geodesics

    First of all, I apologize for not replying during all this time. I started this post in order to code a simple application that can show how a vector is modified while its support point, which lies on a polyhedral surface (since computers work only with discrete representations of...

    Intuitive explanation of parallel transport and geodesics

    Yes, I was trying to answer to lavinia's suggestion of actually cutting a manifold (e.g. sphere) with a knife that contains the normal vector and this way describing a geodesic. I exemplified by cutting along the 45 deg N lat circle. What I did was to squeeze a cone that contained this circle...

    Intuitive explanation of parallel transport and geodesics

    I haven't tried it literally (I suppose a knife and an orange would do..), but I did manage to splash some odd looking depiction of what I'm imaging in a png file. I am cutting along the 45N parallel. My task is: make sure my knife contains the surface normal and that I do not cut something else...

    Intuitive explanation of parallel transport and geodesics

    Let me chime in with what I mean by the "greedy" algorithm. I do believe it's the same concept as proposed here: http://citeseerx.ist.psu.edu/viewdoc/summary?doi=10.1.1.97.5808 What happens when you cut a sphere with a knife along the 45 deg N parallel circle? I bet I can make the knife contain...

    Intuitive explanation of parallel transport and geodesics

    Thank you all for your replies! I didn't want it to sound as if I am ignoring the fact that the sphere is not parallelizable ( aka the HBT). My intuition was to start with a pseudo "up" direction and try to keep your "eyes" in that direction while moving along the curve from two points in such...

    Intuitive explanation of parallel transport and geodesics

    Hello, First of all, please excuse me if I posted in the inappropriate place.. While a student few years ago, I used to work a lot with advanced differential geometry concepts, but never got an intuitive view of HOW humanity got to think about parallel transport, why it contained two words...
