Reference excerpt

William Augustus Edmond Ussher (8 July 1849 – 19 March 1920) was a British geologist. Ussher, born in County Galway, was the youngest of six children in an Irish Protestant family that could trace its ancestry back to Archbishop James Ussher. In April 1868 William Ussher joined the Geological Survey after passing a civil service examination. He retired from the Survey in 1909 after making major contributions to establishing the stratigraphic succession in the Devonian, Carboniferous, and Permian-Triassic rocks in southwestern England, especially Cornwall, Devon, and West Somerset. He contributed articles to the Geological Magazine, the Quarterly Journal of the Geological Society of London, and the Proceedings of the Somersetshire Archaeological and Natural History Society, and several other learned journals. He was awarded the Bolitho Medal of the Royal Geological Society of Cornwall in 1903, and the Murchison Medal of the Geological Society of London in 1914.

Legacy The Ussher Society, named in his honour, was founded in 1962 to promote the study of geology and geomorphology in southwest England. The Devonian crinoid Quantoxocrinus ussheri Webby, 1965 was named in his honour.

Worked examples

Example 1 — a first encounter with William Augustus Edmond Ussher

Start with the simplest possible case. Write down what William Augustus Edmond Ussher claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In earth science, 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 Augustus Edmond Ussher 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 Augustus Edmond Ussher 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 Augustus Edmond Ussher

In research: William Augustus Edmond Ussher appears in earth science 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 Augustus Edmond Ussher 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 Augustus Edmond Ussher is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1849 births, 1920 deaths, British geologists, so understanding it makes those chapters shorter.
In everyday life: Look for William Augustus Edmond Ussher 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.
