"The magnetic field of the Earth has reversed its polarity several hundred times during the past 160 million years. This image shows a simple deterministic model illustrating the geomagnetic reversals.
"In chaos theory, the butterfly effect is the sensitive dependence on initial conditions in which a small change in one state of a deterministic nonlinear system can result in large differences in a later state.
String Theory Infographic: String theory is an active research framework in particle physics that attempts to reconcile quantum mechanics and general relativity. It is a contender for a theory of everything (TOE), a self-contained mathematical model that
