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 ...

Santosh Vempala, along with Richard Peng, came up with a new, faster way of solving certain linear equations, “the workhorse of modern computation” according to Vempala.

We consider a class of iterative algorithms for solving systems of linear equations where the coefficient matrix is nonsymmetric with positive-definite symmetric part. The algorithms are modelled ...
