Using shape functions on the triangle, we are showing an elegant way to map from a reference triangle to a target triangle.

A step further towards understanding automatic differentiation, this time with a tiny example of how to apply the reverse mode.

We're examining what happens when a wave hits a boundary normal to its propagation direction.

I’ve been recently brushing up on statistics and have rediscovered an interesting problem I never fully understood: why do we divide by $n-1$ in the unbiased variance estimator?

Cannonball trajectories, analytical solution and numerical integration.

This post is a tutorial on how to use the meshing program GMSH to draw geometry on top of an image in order to produce a mesh with it.

A short animation of a mass connected to three massless springs.

I’ve had a hard time wrapping my head around the way to code rotations using Euler angles. In this blog post, I’m trying to apply them to the task of rotating a bunny.

Inspired by David JC MacKay’s Sustainable Energy – without the hot air, I estimate the heat losses of my newly bought house and try to ponder the benefits of increased insulation.

I’ve been recently refreshing my finite element skills and found a fun problem that appears when working with 2D meshes made of triangles. The problem is as follows: "Given any 2D triangle T defined by its vertices, can I map it to a reference triangle with vertices (0, 0), (1, 0) and (0, 1)?".
