The physicist who invented topology while watching smoke rings
In short: While James Clerk Maxwell and Lord Kelvin became household names, Peter Guthrie Tait remained a shadow in the history of physics. Yet, his obsession with the geometry of knots led him to pioneer topology and create mathematical conjectures that sat unopened in a library for over a century.
Peter Guthrie Tait (1831–1901) was a prolific mathematical physicist who served as the Professor of Natural Philosophy at the University of Edinburgh starting in 1859. Although he is often overshadowed by his contemporaries Maxwell and Kelvin, Tait was a central figure in 19th-century science, contributing significantly to thermodynamics and the kinetic theory of gases. His career was marked by high-level competition; notably, he narrowly beat Maxwell to the prestigious Edinburgh professorship. He was a versatile researcher who explored a wide range of scientific subjects. His academic standing was secured during a period of intense rivalry in the Scottish university system.
One of Tait's most imaginative contributions arose from a collaborative experiment with Kelvin involving smoke rings. This observation led them to propose a novel atomic theory centered on the concept of knots and links. This pursuit eventually branched off into a distinct mathematical field, establishing Tait as one of the world's first topologists. His work moved beyond mere physics into the abstract study of how shapes can be twisted and joined without being broken. This specific inquiry into the geometry of links eventually took on a mathematical life of its own. It transformed a physical observation into a foundational pillar of modern abstract mathematics.
Tait's legacy includes a series of mathematical conjectures that remained unproven for more than 100 years. These were so significant that they were preserved in an envelope at the National Library of Scotland. Dr. Julia Collins discovered these documents, revealing a narrative of a scientist whose deep theoretical work remained largely inaccessible to the wider world for a century, highlighting the hidden history of mathematical discovery. The historian Maurice Eppel originally directed Dr. Julia Collins toward this specific repository of knowledge. During her search, she even discovered some intriguing scribbles on the back of a different envelope.
