When solving numerical problems like partial differential equations, knowing how accurate your solution is is always important. But how can you know if you don’t have the exact solution for …

Recently, I was a guest at a seminar, where one Ph.D. student gave a presentation about some topic in physics. That student proudly claimed that he had managed to speed …

At school, and also often as undergraduates at college, we learn that polynomials are things …

Have you ever wondered why the Laplacian is so ubiquitous in physics and engineering? I’ve heard many explanations, many of which refer to symmetry considerations, but there is one argument …
