Reference excerpt

John Adrian Bondy (born 1944) is a retired English mathematician, known for his work in combinatorics and graph theory.

Career Bondy received his Ph.D. in graph theory from the University of Oxford in 1969. His advisor was Dominic Welsh. Between 1969 and 1994, Bondy was Professor of Graph Theory at the University of Waterloo in Canada, and then, until his retirement, at Université Lyon 1 in France. From 1976, he was managing editor, and, between 1979 and 2004, co-editor-in-chief (together with U. S. R. Murty) of Journal of Combinatorial Theory, Series B. Throughout his career, Bondy has (co-)authored over 100 publications with 51 co-authors, including the widely influential textbook Graph Theory with Applications (with U. S. R. Murty), and supervised 12 Ph.D. students. His Erdős number is 1. Bondy was dismissed from his tenured position at the University of Waterloo in 1995, after 25 years in which he had been a major contributor to the renown of the University's Department of Combinatorics and Optimization. The reasons for his dismissal centered on "Bondy's acceptance of a teaching post in France, and the acceptability of someone who is on UW's faculty payroll holding a full-time job elsewhere." Protesting the decision, Paul Erdős returned his honorary doctorate to the University of Waterloo, and Vašek Chvátal resigned from his position of Adjunct Professor at the Department of Combinatorics and Optimization.

Personal life Bondy has a passion for photography, having taken pictures since his childhood. In the 1980s, he regularly exhibited his work, most notably at the Kitchener-Waterloo Art Gallery in Kitchener, Ontario. In 2010, Bondy founded the non-profit association Mind's Eye with the aim "to reflect upon the conceptual links between mathematics and photography." In 2012, he opened a photo gallery with the same name on the Rue Saint-Jacques, Paris. Between 2012 and 2022, Mind's Eye / Galerie Adrian Bondy has hosted 42 exhibitions with works of 27 artists, including John Claridge and Jean Dréville.

Worked examples

Example 1 — a first encounter with John Adrian Bondy

Start with the simplest possible case. Write down what John Adrian Bondy claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In chemistry, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to John Adrian Bondy before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about John Adrian Bondy ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of John Adrian Bondy

In research: John Adrian Bondy appears in chemistry research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses John Adrian Bondy in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: John Adrian Bondy is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1944 births, 20th-century English mathematicians, Academic staff of the University of Waterloo, so understanding it makes those chapters shorter.
In everyday life: Look for John Adrian Bondy outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
