Articles in Finnish published in Solmu, a Finnish math magazine mainly aimed at high school students:
Rekonstruktiokonjektuuri verkkoteoriassa. The article is about the reconstruction conjecture in graph theory.
Miksei funktiota e^{-x^2} voi integroida? (Osa 1). The article is about the fact that some elementary functions, like e^{-x^2} do not have elementary antiderivatives. The first part contains the necessary tools to state Liouville's theorem.
