Reference excerpt

William M. Napier (born 29 June 1940) is a Scottish author. Napier is best known for authoring five high tech thriller novels and a number of nonfiction science books.

Career He received his Bachelor of Science degree in 1963 and his Doctor of Philosophy degree in 1966, both from the University of Glasgow. Napier is a professional astronomer who has worked at the Royal Observatory in Edinburgh, the University of Oxford and Armagh Observatory. He is currently an honorary professor of Astrobiology in the Center for Astrobiology at Cardiff University, which describes him as "a leading figure in the dynamics and physics of comets, and a pioneer of the modern versions of catastrophism." He is also an honorary professor at the Buckingham Centre for Astrobiology, University of Buckingham, which describes him as, "a pioneer of modern studies of the impact hazard due to asteroids and comets," and also as having, "carried out an investigation of long-running claims of anomalous QSO/galaxy associations." His research work focuses on comets and cosmology. The result of his collaboration with Victor Clube and others on the role of giant comets in Earth history is known as "coherent catastrophism." According to Napier, 13,000 years ago the earth was affected by a major, rapid cooling event that caused the extinction of a large number of species and a major disruption of paleoindian cultures. Napier argues for the Younger Dryas impact hypothesis that the cooling event was caused by the collision with "a dense trail of material from a large disintegrating comet," {{Cite journal. He is a member of the Comet Research Group, which raises money for, and conducts research in this area as well as biblical archaeology.

Worked examples

Example 1 — a first encounter with William Napier (astronomer)

Start with the simplest possible case. Write down what William Napier (astronomer) claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, 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 Napier (astronomer) 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 Napier (astronomer) 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 Napier (astronomer)

In research: William Napier (astronomer) appears in astronomy 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 Napier (astronomer) 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 Napier (astronomer) is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1940 births, Academics of Cardiff University, Alumni of the University of Glasgow, so understanding it makes those chapters shorter.
In everyday life: Look for William Napier (astronomer) 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.
