Complex Models of Our World

Over the years we tested various theories about our world. We are especially interested in finance, growth dynamics and energy. This webpage is a summary of our efforts so far. New content will be added whenever we find out something interesting. Go here for an introduction.

The Efficient Market Hypothesis only works in a perfect world, obviously not in the real one. Technical Analysis seems to work sometimes, but nobody ever published a mathematical model to proof it. And then there are people investing based on planet constellations.

We wondered for years how financial markets really work. We share our findings and ideas on this webpage. This is not investment advice but will give you some insight you won't get anywhere else. And we think it's very entertaining if you like mathematics and markets.

Example: Fitting the Shanghai house price index (blue curve) with the Bubble Equation (magenta curve) shows that - in case there is really a bubble - we might see a crash before 2014.
