We prove that the lowest upper bound for the number of isolated zeros of the Abelian integrals associated to quadratic Hamiltonian vector fields having a center and an invariant straight line after ...

Line integrals, often perceived as complex mathematical constructs, are fundamental tools in vector calculus and physics. They extend the concept of integration from simple intervals on the real line ...

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 ...
