Reference excerpt

The Patchwork Girl is a science fiction mystery novel by American writer Larry Niven. Part of his Known Space series, it is the fourth of five Gil Hamilton detective stories and the first to be published as a stand-alone novel in 1980. It was later included in the Gil Hamilton anthology Flatlander. In a break from his usual ARM duties, Hamilton is an acting U.N. Delegate on the moon, attending a conference on Lunar Law. The Belt Delegate, Chris Penzler, is shot by a laser in an apparent murder attempt. The shot came from outside of the window of his personal quarters, which looks out onto the lunar surface. The only person known to be outside on the lunar surface at the time of the attempt is Naomi Mitchison, a tourist and old flame of Gil's. Gil believes Naomi to be innocent of shooting Penzler, but suspects that she may be lying in order to hide an equally serious crime. The legal process on Luna acts quickly, and Naomi is condemned to be "broken up" for spare parts, a process which involves her being put in a coma and used as a source of organs for transplant. In stories set in this era, the need for spare parts is so great that even minor crimes carry this sentence. Gil uses his ARM authority to investigate, taking advantage of his "phantom arm", his ability to sense things remotely that he gained after losing one arm in an accident when he lived among the Belters. Although the sense is limited by his perception of his arm's reach, he discovers it can be amplified by a 3-D projection of the lunar surface. Feeling around the projection, he is able to detect a clue left out on the surface by the actual criminal. When he finally solves the mystery, Naomi is revived, but with her beauty destroyed by having body parts removed and then replaced. Her real crime is revealed as one that violates the strict population laws of Earth, and she has to leave and live elsewhere in the Solar System.

References to other works, people "Naomi Mitchison" was the name of a Scottish writer and poet. It is not known if Niven chose the name knowing this.

Worked examples

Example 1 — a first encounter with The Patchwork Girl

Start with the simplest possible case. Write down what The Patchwork Girl 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 The Patchwork Girl 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 The Patchwork Girl 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 The Patchwork Girl

In research: The Patchwork Girl 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 The Patchwork Girl 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: The Patchwork Girl is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1980 American novels, 1980 English-language novels, 1980 science fiction novels, so understanding it makes those chapters shorter.
In everyday life: Look for The Patchwork Girl 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.
