Later career


Complex systems and cellular automata

In 1983, Wolfram left for the School of Natural Sciences of the

in Princeton. By that time, he was no longer interested in particle physics. Instead, he began pursuing investigations into cellular automata, mainly with computer simulations. He produced a series of papers systematically investigating the class of elementary cellular automata, conceiving the Wolfram code, a naming system for one-dimensional cellular automata, and a classification scheme for the complexity of their behaviour. He conjectured that the Rule 110 cellular automaton might be

, which was later proved correct. Wolfram's cellular-automata work came to be cited in more than 10,000 papers. In the mid-1980s, Wolfram worked on simulations of physical processes (such as turbulent fluid flow) with cellular automata on the Connection Machine alongside Richard Feynman and helped initiate the field of

A dispute with the administration over the intellectual property rights regarding SMP—patents, copyright, and faculty involvement in commercial ventures—eventually led him to resign from Caltech. SMP was further developed and marketed commercially by Inference Corp. of Los Angeles during 1983–1988.

which continues to develop and market the program.


''A New Kind of Science''

From 1992 to 2002, Wolfram worked on his controversial book '' A New Kind of Science'', which presents an empirical study of simple computational systems. Additionally, it argues that for fundamental reasons these types of systems, rather than traditional mathematics, are needed to model and understand complexity in nature. Wolfram's conclusion is that the universe is discrete in its nature, and runs on fundamental laws which can be described as simple programs. He predicts that a realization of this within scientific communities will have a revolutionary influence on physics, chemistry, biology, and a majority of scientific areas in general, hence the book's title. The book was met with skepticism and criticism that Wolfram took credit for the work of others.


Wolfram Alpha computational knowledge engine

Wolfram Physics Project

In April 2020, Wolfram announced the "Wolfram Physics Project" as an effort to reduce and explain all the laws of physics within a paradigm of a hypergraph that is transformed by minimal rewriting rules that obey the Church-Rosser property. The effort is a continuation of the ideas he originally described in ''A New Kind of Science.'' Wolfram claims that "From an extremely simple model, we're able to reproduce special relativity, general relativity and the core results of quantum mechanics." Physicists are generally unimpressed with Wolfram's claim, and state that Wolfram's results are non-quantitative and arbitrary.


Personal interests and activities

Wolfram has an extensive log of personal analytics, including emails received and sent, keystrokes made, meetings and events attended, phone calls, even physical movement dating back to the 1980s. In the preface of ''A New Kind of Science'', he noted that he recorded over one-hundred million keystrokes and one-hundred mouse miles. He has stated " ersonal analyticscan give us a whole new dimension to experiencing our lives." Stephen Wolfram was involved as a scientific consultant for the 2016 film '' Arrival''. He and his son Christopher wrote some of the code featured on-screen, such as the code in graphics depicting an analysis of the alien logograms, for which they used the
