Reference excerpt

Oriol Bohigas i Martí (22 December 1937 – 22 October 2013) was a Spanish and French physicist.

Bohigas was born in Barcelona, where he studied physics at the university. In 1966 he became researcher at France's CNRS, where he would stay until the end of his career, becoming Director of Research Emeritus at the LPTMS laboratory (Laboratoire de Physique Théorique et Modèles Statistiques), of which he was one of the founders, at Université de Paris-Sud in Orsay. Before that, he had been head of the Division of Theoretical Physics of the Institute of Nuclear Physics (IPN), on the campus of the same university. He died in Orsay. His fundamental contributions to the theory of quantum chaos and its applications, particularly in nuclear physics, granted him the Gay-Lussac-Humboldt Prize (1991), the Holweck Medal (1999), and an honoris causa doctorate by the Technische Universität Darmstadt, among other recognitions.

Worked examples

Example 1 — a first encounter with Oriol Bohigas Martí

Start with the simplest possible case. Write down what Oriol Bohigas Martí claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, 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 Oriol Bohigas Martí 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 Oriol Bohigas Martí 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 Oriol Bohigas Martí

In research: Oriol Bohigas Martí appears in physics 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 Oriol Bohigas Martí 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: Oriol Bohigas Martí is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1937 births, 2013 deaths, Chaos theorists, so understanding it makes those chapters shorter.
In everyday life: Look for Oriol Bohigas Martí 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.
