This is a collection of the various projects I have spend time on investigating. Curiosity projects that started one way or another, but always driven by my desire to figure things out.

Infinite Gaussians ⚫︎ A trigonometric description of an infinite series of Gaussians

Eduard Friedrich Kärger ⚫︎ The story of a 19th century maths teacher

Typhoid Fever ⚫︎ The little-known epidemic of 1911 in Schneidemühl

Writings ⚫︎ Literature of various kinds, in various languages, from my own hand
