Reference excerpt

Ottery St Mary Astronomical Clock is a 14th-century astronomical clock in St Mary's Church, Ottery St Mary, in Devon in south-west England.

History and description The south transept of the church of St Mary in Ottery St Mary houses the astronomical clock, one of the oldest surviving mechanical clocks in England. It is commonly attributed to Bishop John de Grandisson, who was Bishop of Exeter (1327–1369), and adheres to Ptolemaic cosmology with the Earth at the centre of the Solar System. At the centre of the dial, the Earth is represented by a black ball. The Sun is represented by a gold ball which rotates round the outermost ring of the dial, showing the time. The Moon is represented by a ball which is half white and half black, which turns on its axis to show the phases of the moon. This ball rotates around the middle ring of the dial, numbered to show the days of the lunar month. The clock is similar in its display to the Exeter Cathedral astronomical clock in Devon and the Wimborne Minster astronomical clock in Dorset. After 30 years of silence, the Ottery St Mary clock was restored to working condition in 1907 by John James Hall of Exeter. The rededication service, on 20 May 1907, was attended by the Bishop of Exeter, Archibald Robertson, who formally set the clock going.

Worked examples

Example 1 — a first encounter with Ottery St Mary astronomical clock

Start with the simplest possible case. Write down what Ottery St Mary astronomical clock 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 Ottery St Mary astronomical clock 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 Ottery St Mary astronomical clock 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 Ottery St Mary astronomical clock

In research: Ottery St Mary astronomical clock 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 Ottery St Mary astronomical clock 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: Ottery St Mary astronomical clock is common in secondary-school and first-year university syllabi. It links to neighbouring topics Astronomical clocks in the United Kingdom, Individual clocks in England, Ottery St Mary, so understanding it makes those chapters shorter.
In everyday life: Look for Ottery St Mary astronomical clock 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.
