Reference excerpt

Mathilde Cannat is a French geologist known for her research on the formation of oceanic crust and the tectonic and magmatic changes of mid-ocean ridges.

Education and career Cannat earned her Ph.D. in 1983 from University of Nantes where she worked on ophiolites and tectonic processes. Following her Ph.D., she was a postdoc at Durham University and then she joined the French National Centre for Scientific Research (CNRS) in 1986. In 1992 she obtained a position at the Pierre and Marie Curie University (University of Paris 6) where she remained until she moved to a position at the Institut de Physique du Globe de Paris in 2001. In 2014, Cannat was elected a fellow of the American Geophysical Union who cited her "for fundamental contributions to understanding the accretion of the oceanic lithosphere and crust".

Research Cannat's research centers on magmatism, changes in the oceanic crust, particularly at mid-ocean ridges. Her early research was on ophiolites in California and western Alps, and she used her research on ophiolites to understand processes on the seafloor. In the mid-1990s, Cannat described the formation of the seafloor at slow-spreading mid-ocean ridges, a model posing that new seafloor is formed from rocks that have been tectonically uplifted from the mantle. This idea differed from the processes described for fast-spreading mid-ocean ridges and, in a 2018 interview, she described this as her greatest achievement. Cannat's research can rely on in situ observations, and she has made seventeen deep-sea dives aboard the Nautile.

Worked examples

Example 1 — a first encounter with Mathilde Cannat

Start with the simplest possible case. Write down what Mathilde Cannat claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In mathematics, 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 Mathilde Cannat 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 Mathilde Cannat 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 Mathilde Cannat

In research: Mathilde Cannat appears in mathematics 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 Mathilde Cannat 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: Mathilde Cannat is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1962 births, Academics of Durham University, Fellows of the American Geophysical Union, so understanding it makes those chapters shorter.
In everyday life: Look for Mathilde Cannat 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.
