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 ...

This is essentially the Euler method. We can use it because computers are fast ... Third, if you are not careful your numerical model can do weird stuff. Suppose I have a mass (m) on a horizontal ...

The focus will be (a) iterative solution methods for linear and non-linear equations, (b) spatial discretization and meshing (c) finite difference methods (FDM ... to illustrate the broad ...

It isn't cheating, it's a legitimate method. If the results of the numerical calculation agree with actual data, then it works. It's that simple. Sometimes we can use numerical methods to find the ...
