Reference excerpt

William Philip Hiern (19 January 1839, in Stafford – 28 November 1925, in Barnstaple) was a British mathematician and botanist. The standard author abbreviation Hiern is used to indicate this person as the author when citing a botanical name.

Life Hiern attended St. John's College, Cambridge, from 1857 to 1861 and attained a first class degree in mathematics. Later, in 1886, he attended Oxford University. Upon his marriage he moved to Surrey and developed an interest in botany. In 1881, Hiern moved to Barnstaple in north Devonshire, and lived at the manor house adjacent to the Barnstaple Castle mound. Hiern was quite taken with the country squire role and he assumed many public duties including those of the Lord of the Manor of Stoke Rivers, northeast of Barnstaple, and he was one of the original aldermen of the County of Devon. For a one-year term from 1916 to 1917, he was the president of the Devonshire Association.

Contributions Hiern published over 50 works on botanical subjects. Among his chief works was the catalogue of the plants Friedrich Welwitsch had collected in Angola. His botanical specimens are stored at Exeter's Royal Albert Memorial Museum, at Kew Gardens, and at Cambridge.

Awards and honours In 1903, Hiern was elected a fellow of the Royal Society. The African figwort genus Hiernia was named in his honor, as was the Ixora hiernii (a tropical evergreen shrub), the Pavetta hierniana (an evergreen shrub) and the Coffea canephora var hiernii (a species of coffee plant). Gabon Ebony (Diospyros crassiflora, itself the source of much taxonomic confusion over the years) was also first described by Hiern in 1873.

Worked examples

Example 1 — a first encounter with William Philip Hiern

Start with the simplest possible case. Write down what William Philip Hiern 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 William Philip Hiern 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 William Philip Hiern 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 William Philip Hiern

In research: William Philip Hiern 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 William Philip Hiern 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: William Philip Hiern is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1839 births, 1925 deaths, 19th-century British mathematicians, so understanding it makes those chapters shorter.
In everyday life: Look for William Philip Hiern 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.
