Peter (chief mouser)

Peter (chief mouser) is a science 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 Peter (chief mouser) rather than just read about it. In short: Peter was a cat who served as Chief Mouser to the Cabinet Office of the United Kingdom between 1929 and 1946. Whilst Peter was the second cat to serve in this role, he is often considered the first, as his predecessor, Treasury Bill, served for less than a year, and was not officially given the title.

Key takeaways

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

Reference excerpt

Peter was a cat who served as Chief Mouser to the Cabinet Office of the United Kingdom between 1929 and 1946. Whilst Peter was the second cat to serve in this role, he is often considered the first, as his predecessor, Treasury Bill, served for less than a year, and was not officially given the title. Peter is described as being a black cat, and was a resident at the Home Office at the time of his appointment. In 1929, the Treasury agreed to allow one penny daily for Peter's upkeep, which included his food and wellbeing requirements. Until the approved spending bill began to better regulate Peter's diet, civil servants had been bringing Peter an excess of food through the day, causing him to neglect his primary role of catching mice. His newly limited diet proved effective at encouraging Peter to catch rodents. It was remarked that when the Home Office was relocated to Bournemouth during World War II, Peter's services were missed so much that they applied for allowances for the upkeep of two cats. Peter was considered by civil servants to have performed "admirably" in his role. He served under five prime ministers in Conservative, Labour and coalition governments, during a period of British history defined by the Great Slump and World War II. Peter's tenure defined multiple precedents for the Chief Mouser position, which have been emulated by his successors in the role. Peter and a later office holder Peter III are jointly the longest serving Chief Mousers since records began, both having served for approximately 17 years.

Worked examples

Example 1 — a first encounter with Peter (chief mouser)

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

In research
Peter (chief mouser) appears in 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 Peter (chief mouser) 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
Peter (chief mouser) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Chief mousers to the Cabinet Office, Individual cats in the United Kingdom, so understanding it makes those chapters shorter.
In everyday life
Look for Peter (chief mouser) 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.
