Are mathematical equations the best way to model nature? For many years it had been assumed that they were. But in the early 1980s, Stephen Wolfram made the radical proposal that one should instead build models that are based directly on simple computer programs. Wolfram made a detailed study of a class of such models known as cellular automata, and discovered a remarkable fact: that even when the underlying rules are very simple, the behavior they produce can be highly complex, and can mimic many features of what we see in nature. And based on this result, Wolfram began a program of research to develop what he called ?A Science of Complexity.?The results of Wolfram's work found many applications, from the so-called Wolfram Classification central to fields such as artificial life, to new ideas about cryptography and fluid dynamics. This book is a collection of Wolfram's original papers on cellular automata and complexity. Some of these papers are widely known in the scientific community; others have never been published before. Together, the papers provide a highly readable account of what has become a major new field of science, with important implications for physics, biology, economics, computer science and many other areas.

This book provides an overview of the directions that lattice gas research has taken from 1986 to early 1989. It shows potential users and lattice gas scientists what research has been completed and gives some indication of the utility and limitations of lattice gas models.

With over a million users around the world, the Mathematica software system created by Stephen Wolfram has defined the direction of technical computing for the past decade. The enhanced text and hypertext processing and state-of-the-art numerical computation features will ensure that Mathematica 4, takes scientific computing into the next century.The Mathematica Book continues to be the definitive reference guide to this revolutionary software package and is released in this new edition to coincide with the release of the new version of Mathematica.The Mathematica Book is a must-have purchase for anyone who wants to understand the opportunities in science, technology, business, and education made possible by Mathematica 4. This encompasses a broad audience of scientists and mathematicians; engineers; computer professionals; financial analysts; medical researchers; and students at high-school, college, and graduate levels. Written by the creator of the system, The Mathematica Book includes both a tutorial introduction and complete reference information, and contains comprehensive description of how to take advantage of Mathematica's ability to solve myriad technical computing problems and its powerful graphical and typesetting capabilities.

The Hidden Workings of Machine LearningWhy does machine learning work at all? Neural networks power everything from image recognition to language models, yet the science behind their success remains strangely elusive. In this essay, Stephen Wolfram strips machine learning down to its barest forms minimal models built from simple rules and shows that even at this level, systems can learn. What emerges is a surprising picture: machine learning doesn't rely on carefully engineered structures but on the natural complexity of the computational universe.Seen this way, machine learning is less about hidden design and more about sampling complexity. Wolfram's exploration offers not only clarity about why AI works but also perspective on its limits why some successes resist explanation, and why the field may never yield a simple unifying theory.

A Metamodel for Foundations of MedicineWhat would a general theory of medicine look like? Stephen Wolfram proposes one grounded in computation. By evolving simple programs as model organisms, he shows how perturbations can stand in for disease and how counter-perturbations can mimic treatment, with genetic diversity reflected in variant rules. The results mirror core challenges of medical science: the wide range of outcomes, the difficulty of prognosis and the uneven success of treatments. The essay positions medicine alongside physics and evolution as a domain whose essential features can be captured in abstract computational form.This is not applied biomedicine but a research agenda: an invitation to study medicine's foundations with computation as the guiding principle. It points towards a future in which algorithmic models deepen our intuition for health, disease and healing.
