 * APS film format is introduced.

Publications

 * May – Sokal affair: American mathematical physicist Alan Sokal hoaxes the editors into publishing a deliberately nonsensical paper, "Transgressing the Boundaries: Toward a Transformative Hermeneutics of Quantum Gravity", in a "science wars" issue of the journal Social Text (Duke University Press) as a critique of the intellectual rigor of postmodernism in academic cultural studies.
 * Belgian physical chemist Ilya Prigogine publishes La Fin des certitudes (translated as The End of Certainty: time, chaos, and the new laws of nature).
 * French-born archaeologist Denise Schmandt-Besserat publishes How Writing Came About.
