Reference excerpt

Stephen Robert Nockolds, FRS (10 May 1909 – 7 February 1990) was a geochemist, petrologist and winner of the Murchison Medal of the Geological Society of London.

Early life and education Robert Nockolds was born at St Columb Major, Cornwall, the son of Dr Stephen Nockolds, a surgeon of Brighton, and his wife Hilda Tomlinson. He was educated at Ascham St Vincent's School, Eastbourne and at Felsted School where his interest in rocks already manifested itself. He then went to Manchester University and then took a PhD at Trinity College, Cambridge.

Career He became a Fellow of Trinity College, and lectured in petrology at Cambridge. In 1957 he became Reader in Geochemistry at Cambridge, and Emeritus Reader. In 1959 he became a Fellow of the Royal Society, and was also an Honorary Fellow of the Geological Society of India. In 1972 he retired from Cambridge and was awarded the Murchison Medal of the Geological Society. He published a leading work on petrology and a large number of papers in various journals as shown below.

Personal life In 1932 he married Hilda Jackson (1909–1976) and subsequently after she died in 1976 he married Patricia Horsley (1923 – 10 July 2013). He was known to his friends as Nocky or Bob and whilst he didn't have children of his own he was affectionately embraced by Patricia's large family.

Worked examples

Example 1 — a first encounter with Stephen Robert Nockolds

Start with the simplest possible case. Write down what Stephen Robert Nockolds 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 Stephen Robert Nockolds 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 Stephen Robert Nockolds 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 Stephen Robert Nockolds

In research: Stephen Robert Nockolds 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 Stephen Robert Nockolds 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: Stephen Robert Nockolds is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1909 births, 1990 deaths, 20th-century English chemists, so understanding it makes those chapters shorter.
In everyday life: Look for Stephen Robert Nockolds 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.
