His sf novels <i>Wheelers</i> (<b>2000</b>) and <i>Heaven</i> (<b>2004</b>), together with the nonfiction <i>The Collapse of Chaos: Discovering Simplicity in a Complex World</i> (<b>1994</b>) and other popular-science works of sf interest, were written in collaboration with Jack <a href="/entry/cohen_jack">Cohen</a> – whom see for further discussion. The <b>Wheelers</b> series prequel <i>Oracle</i> (<b>2021</b>), opening on Earth in 17,000 BCE but featuring galaxy-wide action, was written by Stewart alone after Cohen's death, making extensive use of his ideas.</p> <p>Stewart, whose solo nonfiction works deal with <a href="/entry/mathematics">Mathematics</a>, was the fourth writer of the <i>Scientific American</i> column founded by Martin <a href="/entry/gardner_martin">Gardner</a> as "Mathematical Games" and continued by Douglas <a href="/entry/hofstadter_douglas">Hofstadter</a> and A K <a href="/entry/dewdney_a_k">Dewdney</a>: Stewart's columns were titled "Mathematical Recreations". Several collections of these and related popular-maths essays have appeared under generally punning titles, beginning with <i>Game, Set & Math: Enigmas and Conundrums</i> (coll <b>1989</b>). Science-fictional themes and trappings frequently appear. Also of tangential interest is Stewart's involvement with what might be termed a mathematics <a href="/entry/fanzine">Fanzine</a>, <i>Manifold</i>, published from the University of Warwick 1968-1980; inspired by Martin <a href="/entry/gardner_martin">Gardner</a>'s columns, this mingled serious, comic and bizarre mathematical speculations, partially collected as <i>Seven Years of Manifold 1968-1980</i> (anth <b>1981</b>) edited by Stewart and John Jaworski.</p> <p><i>The Science of Discworld</i> (<b>1999</b>) with Jack <a href="/entry/cohen_jack">Cohen</a> and Terry <a href="/entry/pratchett_terry">Pratchett</a> and its sequels use Pratchett's <b>Discworld</b> as a launch pad for highly readable popular-science commentary, each time appearing between the chapters of a novella by Pratchett solo. <i>Flatterland: Like Flatland Only More So</i> (<b>2001</b>) uses Edwin A <a href="/entry/abbott_edwin_a">Abbott</a>'s <i>Flatland</i> (<b>1884</b>; rev <b>1884</b>) as the starting point for a <a href="/entry/flatland">Flatland</a> girl's fictionalized tour (with much wordplay in echo of Lewis <a href="/entry/carroll_lewis">Carroll</a>) of more modern mathematical concepts of <a href="/entry/dimensions">Dimensions</a>, geometries, topology and so one, including an sf excursion into <a href="/entry/black_holes">Black Holes</a> and <a href="/entry/time_paradoxes">Time Paradoxes</a>.</p> <p>Further sf novels are <i>The Living Labyrinth</i> (<b>2016</b>) and its sequel <i>Rock Star</i> (<b>2017</b>), both with Tim Poston (1945-2017), being two-thirds of an intended trilogy; and <i>Loophole</i> (<b>2023</b>).
