This post is a follow up to my introduction to partial differential equations. As I mentioned in the other post, it is sometimes not possible to find an expression for the solution to a PDE. So, how can be be sure that the solution even exists? And does it even make sense to talk about …

Since my studies currently involve a lot of partial differential equations (PDEs) I thought a brief introduction might be in order. I’ll start by introducing ordinary differential equations (ODEs) first, since they are in many ways very similar. When you solve an ordinary equation like \( 2x^2 – 3x = 5 \) you want to …

So, after much waiting, the new Samsung SyncMaster 2233RZ arrived at the webshops here in Norway. I ordered one at about 1430 friday and picked it up at my local post office at 1230 the very next day. And boy is it nice. Words can hardly describe it. Just moving windows around is a joy. …

Finally found some time to experiment with Blender’s Fluid simulator. Very easy to use, however I quickly discovered that an OpenMP enabled build would have been preferable, as well as a x64 version. I started simple with a drop hitting the floor, and rendered it using LuxRender. My poor Q6600 spent roughly 80 cpu-hours on it. …
