Their means of analysing the data invokes what is known as nonlinear dynamics - a mathematical approach that has been used to explain a wide range of physical phenomena in which a number of factors play a part.0 f' ~5 d! n& ~. O {6 r

One of the team, Daniel Abrams of Northwestern University, put forth a similar model in 2003 to put a numerical basis behind the decline of lesser-spoken world languages.

The team then applied their nonlinear dynamics model, adjusting parameters for the relative social and utilitarian merits of membership of the \"non-religious\" category.

And in all the countries, the indications were that religion was headed toward extinction.

However, Dr Wiener told the conference that the team was working to update the model with a \"network structure\" more representative of the one at work in the world.
