Extracting Pi from Chaos

SummaryWe present an experimental method to find some digits of π, by extracting it from chaos generated by a quadratic polynomial. In fact, we iterate the logistic map in its chaotic regime, and show how to extract the digits of π out of those chaotic numbers. Additional informationNotes on contributorsMilton F. MaritzMilton F.
