SourcesWhere this comes from
24 sources — the papers that built the field, and the books to read next. Every claim on this site traces to one of these; every figure is computed by the code, not taken from them.
- Henri Poincaré, “Sur le problème des trois corps et les équations de la dynamique”, Acta Mathematica 13 (1890) 1–270 — the first sight of a system whose future depends without limit on where it began. ↗
- Henri Poincaré, Science et méthode (1908), book I, chapter 4: “a very small cause, which escapes us, determines a considerable effect which we cannot help seeing.” ↗
- Jacques Hadamard, “Les surfaces à courbures opposées et leurs lignes géodésiques”, Journal de mathématiques pures et appliquées 4 (1898) 27 — nearby paths on a curved surface pulling apart exponentially. ↗
- Aleksandr Lyapunov, The General Problem of the Stability of Motion (1892, doctoral thesis, Kharkov); English translation, Taylor & Francis 1992 — the exponent that measures how fast neighbours separate. ↗
- Edward N. Lorenz, “Deterministic Nonperiodic Flow”, Journal of the Atmospheric Sciences 20 (1963) 130–141 — three equations for convection, and the discovery that they never repeat. ↗
- Edward N. Lorenz, “Predictability: Does the Flap of a Butterfly's Wings in Brazil Set Off a Tornado in Texas?”, address to the AAAS, 29 December 1972. ↗
- Robert M. May, “Simple mathematical models with very complicated dynamics”, Nature 261 (1976) 459–467 — the logistic map, and a call to teach it in schools. ↗
- Tien-Yien Li & James A. Yorke, “Period Three Implies Chaos”, American Mathematical Monthly 82 (1975) 985–992 — the paper that put the word “chaos” into mathematics. ↗
- Mitchell J. Feigenbaum, “Quantitative universality for a class of nonlinear transformations”, Journal of Statistical Physics 19 (1978) 25–52 — the constant 4.669, the same for a whole class of maps. ↗
- David Ruelle & Floris Takens, “On the nature of turbulence”, Communications in Mathematical Physics 20 (1971) 167 — the phrase “strange attractor”. ↗
- Benoit Mandelbrot, “How Long Is the Coast of Britain? Statistical Self-Similarity and Fractional Dimension”, Science 156 (1967) 636. ↗
- Stephen Smale, “Differentiable dynamical systems”, Bulletin of the AMS 73 (1967) 747 — the horseshoe: stretch and fold, the engine under every chaotic map. ↗
- Giancarlo Benettin, Luigi Galgani, Antonio Giorgilli & Jean-Marie Strelcyn, “Lyapunov Characteristic Exponents for smooth dynamical systems”, Meccanica 15 (1980) 9 — the method used here to measure the exponent. ↗
- Stanisław Ulam & John von Neumann, “On combination of stochastic and deterministic processes”, Bulletin of the AMS 53 (1947) 1120 — the map x → 4x(1−x) as a source of pseudo-random numbers, and its arcsine distribution. ↗
- Jacob Bernoulli, Ars Conjectandi (Basel, 1713), part IV — the first proof that the observed frequency closes on the true chance as the trials pile up. His “golden theorem”. ↗
- Andrey Kolmogorov, Grundbegriffe der Wahrscheinlichkeitsrechnung (1933); English, Foundations of the Theory of Probability, Chelsea 1956 — the strong law and the axioms under it. ↗
- Harry Markowitz, “Portfolio Selection”, Journal of Finance 7 (1952) 77–91 — spreading a stake across uncorrelated bets shrinks the swing without shrinking the return. ↗
- C. S. Holling, “Resilience and Stability of Ecological Systems”, Annual Review of Ecology and Systematics 4 (1973) 1–23 — resilience as the size of the shock a system can take and still recover, as distinct from how fast it returns. ↗
- James Clerk Maxwell, “On Governors”, Proceedings of the Royal Society 16 (1868) 270 — the mathematics of a machine that corrects its own error, the ancestor of control theory. ↗
- Norbert Wiener, Cybernetics: or Control and Communication in the Animal and the Machine (MIT Press, 1948) — feedback as the common thread of stable systems, living and built. ↗
- Steven H. Strogatz, Nonlinear Dynamics and Chaos, 2nd ed. (Westview/CRC, 2015) — the standard undergraduate text, and a kind one. ↗
- James Gleick, Chaos: Making a New Science (Viking, 1987) — how the field came together, told for everyone. ↗
- Nassim Nicholas Taleb, Antifragile: Things That Gain from Disorder (Random House, 2012) — a working vocabulary for things that get stronger under stress, not merely survive it. ↗
