Stephen Peter Rigaud

Stephen Peter Rigaud is a astronomy 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 Stephen Peter Rigaud rather than just read about it. In short: Stephen Peter Rigaud (12 August 1774 – 16 March 1839) FRAS was an English mathematical historian and astronomer. Rigaud was born into a French Protestant family.

Key takeaways

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

Reference excerpt

Stephen Peter Rigaud (12 August 1774 – 16 March 1839) FRAS was an English mathematical historian and astronomer. Rigaud was born into a French Protestant family. His father, Stephen (also known as James Stephen) Rigaud, was Observer at the Kew Observatory. The painter John Francis Rigaud, who painted a portrait of Rigaud, aged four, and his sister Mary Anne was not his uncle but other possible connections are unknown. He was a Fellow of Exeter College, Oxford, from 1794 to 1810, held the Savilian Chair of Geometry at the University of Oxford from 1810 to 1827, and was Savilian Professor of Astronomy from 1827 to 1839. He lived at 21 Richmond Green in Richmond, Surrey (now Richmond, London) from 1815 to 1826. "He devoted his leisure to research and authorship in the field of scientific biography. A well-informed friend has said of him, — " He had a peculiar delight in tracing the history of an invention, or illustrating the biography of those who, however eminent in their day, were in after ages known to have lived, flourished for a time, and died. To collect the materials for their lives, to throw light upon their habits, enumerate their works, and do justice to their merits, was a principal source of his amusement; and his perseverance in seeking for materials was exceeded only by the discrimination and impartiality which accompanied his researches and rendered them of permanent value."

Published works Historical essay on the first publication of Sir Isaac Newton’s Principia (1838) An account of some early proposals for steam navigation (1838) Defence of the resolution for omitting Mr Panizzi's bibliographical notes from the catalogue of the Royal Society (1838) Correspondence of scientific men of the seventeenth century: including letters of Barrow, Flamsteed, Wallis and Newton, printed from the originals in the collection of the Honorable the Earl of Macclesfield (1841)

Death and legacy

He died on 16 March 1839 and was buried at St James, Piccadilly, London, where a memorial to him lies in the church. His eldest son, Stephen Jordan Rigaud (1816–1859), was an English clergyman and schoolmaster who became Bishop of Antigua. Some of his large book collection, concerning astronomy, mathematics and physics, was purchased by the Radcliffe Observatory in Oxford. Some of the remaining materials were presented to the Bodleian Library in 1935 and some were sold at auction. This collection at the Bodleian contains 840 books. The theological, classical and miscellaneous portion of his library was sold at auction in London by R. H. Evans on 6 August 1839 (and two following days); a copy of the catalogue is held at Cambridge University Library (shelfmark Munby.c.145(11)).

Worked examples

Example 1 — a first encounter with Stephen Peter Rigaud

Start with the simplest possible case. Write down what Stephen Peter Rigaud 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 Stephen Peter Rigaud 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 Peter Rigaud 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 Peter Rigaud

In research
Stephen Peter Rigaud 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 Stephen Peter Rigaud 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 Peter Rigaud is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1774 births, 1839 deaths, 19th-century English astronomers, so understanding it makes those chapters shorter.
In everyday life
Look for Stephen Peter Rigaud 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.
