Using Lagrange multipliers to calculate forces of constraint! 🔩⚙️ In this video, we dive deep into the power of Lagrangian mechanics to handle systems with constraints. Learn how to use Lagrange ...

We propose fully discrete schemes to approximate the harmonic map heat flow and wave maps into spheres. The finite-element based schemes preserve a unit length constraint at the nodes by means of ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...
