    That was beautifully clear. I really liked how you presented that.

    Amazing that an NFL player is a top mathematician and programmer!

    Great video! I've been doing Poison in my Uni last week in Julia too. One thing I can recommend is to declare global variables as "const" if you don't change them. It sped up my global/local relaxation Poison solver from 17min to 75sec, just by giving const to variables. Good luck.

    Your explanation is very clear. Thank you! Please make more such videos.

    Very well done. This reminds me of my 8.022 class with Claude Canizares (in 1977!), who told us about the method of relaxation - push the button and relax.

    Great Talk! I did the same thing for my term paper using the Gauss-Seidel method instead of Jacobi.

    Nice! I use Multigrid to solve the pressure poisson equation for fluid simulation in my code on github if anyone is interested. github.com/weymouth/WaterLily The multi-grid part is only around 50 lines of code and works in 2D or 3D.

    I wonder if this kind of method can help speed up high resolution ray tracing.

    Incredible content, are any of these speakers taking students in your group?

    he mentioned something like solving by hand using superposition and fourier series, can kindly someone elaborate on this?

      look into separation of variables for the laplace equation in 2d
