I feel a bit like celebrating. During the weekend I have browsed and read through about 300 pages of our book on numerical methods ("Numerical Methods in practice", written in Finnish). The second edition contains some new topics, notably Fourier and wavelet transforms and adative finite elements. We have managed to keep the book concise, increasing the length to about 414-415 pages, less than 30 pages more than in the first edition.

The update has taken on and off almost a year. Not, while finishing the book, I have become quite focused on the topic. It seems almost a pity to let go. There are facts to check, new developments to follow, and lots of things to verify. On the other hand, "best is an enemy of the good", as a professor of physics once said. Sometimes you just have to let go.
