Reference excerpt

Hazel Rossotti (1 February 1930 – 24 December 2023) was a British chemist and science writer.

Early life and education Rossotti (née Marsh) left Millfield School in 1948 and completed her undergraduate and PhD at the University of Oxford. Her research considered the stability of metal-ion complexes, and she worked under the supervision of Robert Williams. In 1952 she married fellow chemist Francis J.C. Rossotti, a fellow graduate student, at St Peter-in-the-East, now part of St Edmund Hall, Oxford.

Career In 1962 Rossotti was appointed a Fellow and Tutor in chemistry at St Anne's College, Oxford, and retired in 1997. She was an advisor to Mary Archer, and an Emeritus Fellow at St Anne's College, Oxford. Rossotti held a long-standing passion for photography, and became known as an accomplished photographer. She specialised in black and white portraits, often of scientists and other colleagues. In 1974, Rossotti nominated French artist and photographer Henri Cartier-Bresson for an honorary doctorate at the University of Oxford. To mark this award, Cartier-Bresson gifted Rossotti a silver gelatine print of a 1938 photograph of 'Sunday on the Banks of the River Seine'. This print is now held in the Bodleian libraries. In 1997, Rossotti designed and made the stained glass panels in the library building, Hartland house.

Books Rossotti published numerous science books, on diverse topics from chemistry to colour, fire and Greece. Oliver Sacks remarked that Rossotti was a born teacher and writer, 'incapable of writing a dull word'.

Worked examples

Example 1 — a first encounter with Hazel Rossotti

Start with the simplest possible case. Write down what Hazel Rossotti 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 Hazel Rossotti 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 Hazel Rossotti 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 Hazel Rossotti

In research: Hazel Rossotti 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 Hazel Rossotti 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: Hazel Rossotti is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1930 births, 2023 deaths, Alumni of St Hugh's College, Oxford, so understanding it makes those chapters shorter.
In everyday life: Look for Hazel Rossotti 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.
