Crack the Enigma
A simplified Bletchley Park learning simulation showing how crib-based reasoning and logical constraints reduce Enigma settings step by step.
Discover π: Newton, Generalized Binomial Series, and Slow Convergence
Advanced historical-mathematical simulation: estimate π from quarter-circle area using Newton’s generalized binomial expansion and integration, and see why this direct method converges painfully slowly.
