Gethyn Hewan

Gethyn Hewan is a mathematics topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Gethyn Hewan rather than just read about it. In short: Gethyn Elliot Hewan (23 December 1916 – 1 July 1988) was an English first-class cricketer and schoolmaster. He studied mathematics as the University of Cambridge, during which he played first-class cricket for Cambridge University Cricket Club, before accepting a fellowship to study at Yale University.

Key takeaways

  • Gethyn Hewan belongs to mathematics; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Gethyn Hewan to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Gethyn Hewan from memory before moving on to harder problems.

Reference excerpt

Gethyn Elliot Hewan (23 December 1916 – 1 July 1988) was an English first-class cricketer and schoolmaster. He studied mathematics as the University of Cambridge, during which he played first-class cricket for Cambridge University Cricket Club, before accepting a fellowship to study at Yale University. He served in the Second World War with the Royal Horse Artillery, for which he was mentioned in dispatches. Following the war he took up teaching posts at several educational establishments, most notably as headmaster of Cranbrook School, Sydney.

Early life and first-class cricket Born at Edinburgh, Hewan was educated at Marlborough College, where he was taught by Brian Hone. From Marlborough he went up to Clare College, Cambridge to study mathematics. He debuted in first-class cricket for Cambridge University in 1938 against the Free Foresters at Fenner's, with Hewan making a total of six first-class appearances for the university in 1938, which was to be his only season of first-class cricket. A bowling all-rounder, Hewan scored 187 runs at an average of 20.77, with a high score of 88. With his off break bowling, he took 20 wickets at a bowling average of 36.25, with best figures of 6/91. These figures, one of two five wicket hauls he took, came against Oxford University. He was awarded a blue in cricket, alongside one in hockey. He was awarded the Andrew Mellon Fellowship to study at Yale University, travelling to the United States in 1938. He graduated with a major in mathematics.

World War II and move to Australia With the outbreak of the Second World War in 1939, Hewan returned to England and enlisted in the British Army, joining the Royal Horse Artillery. He saw action in North Africa, including at Tobruk. He was mentioned in dispatches in November 1945 in recognition of gallantry and distinguished service in North-West Europe. Following the conclusion of the war he was appointed as the mathematics master at Wellington College, Berkshire. Relocating to Berkshire saw Hewan play minor counties cricket for Berkshire in 1946, making two appearances in the Minor Counties Championship. On the recommendation of Hone, he became the headmaster of Cranbrook School in Sydney. He accepted the position in November 1950, he relinquished his commission in the Royal Horse Artillery in July 1951, upon which he was granted the honorary rank of major. In Australia, he was a founding member of the Australian College of Education, and was a strong supporter of the Outward Bound movement. He was a promoter of the house system at Cranbrook, as well as promoting the benefits of extra-curricular activities to its pupils. He oversaw a number of new developments at the school, including the War Memorial Hall in 1953, Dickins House in Rose Bay in 1959 as the Cranbrook Preparatory School, and the Science Building which was opened in 1962. He was a keen amateur golfer, winning the Royal Sydney Golf Championship eight times. He resigned as the headmaster of Cranbrook in 1963, nominating Mark Bishop as his successor.

Return to England and later life He returned to England shortly after, where he took up master posts at Winchester College and Charterhouse School. He took up the post of headmaster at Allhallows School in Lyme Regis, a position he held from 1965 to 1973. During his tenure as headmaster he oversaw a period of modernisation at the school. He announced his retirement on the grounds of ill health at the end of the 1973 summer term. He died at Chertsey in July 1988, and was survived by his wife Peggy, who died aged 96 in 2010, and their three children.

Worked examples

Example 1 — a first encounter with Gethyn Hewan

Start with the simplest possible case. Write down what Gethyn Hewan 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 Gethyn Hewan 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 Gethyn Hewan 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 Gethyn Hewan

In research
Gethyn Hewan 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 Gethyn Hewan 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
Gethyn Hewan is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1916 births, 1988 deaths, 20th-century English sportsmen, so understanding it makes those chapters shorter.
In everyday life
Look for Gethyn Hewan 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.
