Reference excerpt

Peter's Pocket Grandpa was a fictional character in a comic strip in the UK comic magazine The Dandy. The comic first appeared in issue #1771, dated 1 November 1975, and was drawn by Ron Spencer for the majority of its run, with a few later strips being drawn by John Geering. The strip was essentially an updated version of another strip called "Jimmy's Pocket Grandpa", which had exactly the same premise and had first appeared in the Dandy in 1940. The strip told the rather whimsical and sad story of a schoolboy named Peter Parker, who lived with his parents and grandfather in perfectly ordinary circumstances until a visit to a fairground left a gypsy angry after an argument with Grandpa. The gypsy promptly put a curse on Grandpa which left him just six inches tall. As a result, the adventures of the family mainly centred on Peter and his Grandpa, who was in constant danger of being eaten by cats, closed inside books etc., but also handy for getting through tight gaps on various archetypal schoolboy adventures. It ran until the early 1980s, and later inspired the Viz strip Mickey's Miniature Grandpa. From 2009 to 2014, a program called Grandpa in My Pocket appeared on CBeebies, based on the comic.

Worked examples

Example 1 — a first encounter with Peter's Pocket Grandpa

Start with the simplest possible case. Write down what Peter's Pocket Grandpa 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's Pocket Grandpa 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's Pocket Grandpa 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's Pocket Grandpa

In research: Peter's Pocket Grandpa 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's Pocket Grandpa 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's Pocket Grandpa is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1975 comics debuts, British comics characters, British comics stubs, so understanding it makes those chapters shorter.
In everyday life: Look for Peter's Pocket Grandpa 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.
