Daisyworld

Abstract

In this thesis, the Daisy-world planetary model is studied. We describe the Gaia principle first. According to this hypothesis, life and climate are viewed as two elements of a coupled system. The climate has the Earth factors and temperature control. They are too complicated to be mathematically modeled, and so we are considering a ”Daisy-world” model. In this model, the earth is populated by only two daisies (black and white), and mathematical equations are used to explain the growth rate of daises, their local temperature, and also the effect temperature. In addition, we also consider the albedo effect on the temperature, stabilization of model, and model relevance to Earth.
