#### Future Learn Basic SIR Model

This is the first in a series of models that explore the dynamics of and policy impacts on infectious diseases. This basic  model divides the population into three categories -- Susceptible (S), Infectious (I) and Recovered (R).

#### Chaos 101: Lorenz Equations

The Lorenz Equations are a simplified model of atmospheric convection comprising three-dimensional differential equations.

The equations have three parameters (A, B, and C) that can be varied to create periodic and aperiodic (chaotic) behaviour.

#### Chaos 101: Logistic Equation

This Insight has been set up to explore the properties of the logistics equation.  The logistics equation is a very simple model of a population where there is some limit to growth.  It is often cited as an archetypal example of how complex, chaotic behaviour can arise from very simple non-linear dy

#### Degree Day Model

This Insight has been developed to explore the relationship between climate change and the number of heating and cooling degree days.  The model has been calibrated using data for New York that accounts for future climate change.

#### ST101: Introduction to Systems Dynamics: Variables 1

This Insight has been developed as an introduction to the basics of Systems Dynamics as part of a series of models to explore the dynamics of growth and decline in a simple environment.  It is the second Insight in a series of four.  The first Insight can be found

#### ST101 Leaky Bucket Model

Simple model of a leaky bucket with a fixed fill rate and an empty rate that is dependent on the size of the hole in the bucket and the height of water.  Can you save Guppy the fish who lives in the bucket?

#### Daisyworld v5b

This Insight is a model of Daisyworld created by James Lovelock in 1982 to demonstrate the central idea behind the Gaia hypotheses that life and the environment may be considered two parts of a coupled system.

#### Basic Climate Model 101: Role of Oceans

A simple Energy Balance Climate Model of the Earth with no atmosphere.  Explore the impact of changing the ocean's depth (i.e. heat capacity) and the pattern of solar radiation on the earth's temperature by using the sliders in the panel below.
