Starquake (novel)

Starquake (novel) 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 Starquake (novel) rather than just read about it. In short: Starquake is a science fiction novel by American writer Robert L. Forward, published in 1985.

Key takeaways

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

Reference excerpt

Starquake is a science fiction novel by American writer Robert L. Forward, published in 1985. It is a sequel to his novel Dragon's Egg. It is about the life of the Cheela civilization, creatures who live on a neutron star named Dragon's Egg, struggling to recover from a disastrous starquake. The novel was listed by theoretical physicist Sean M. Carroll as his favorite science fiction novel.

Plot introduction This story begins at the exact time that Dragon's Egg (its predecessor) ended. As the human scientists in the orbiting ship Dragon Slayer prepare to leave, the Cheela on the star below continue their rapid advance. Starquake centers around two crises. The first is when the human ship is damaged, and the Cheela must repair the ship before tidal forces kill the humans aboard. Then a catastrophic Starquake strikes. Cheela explorers in space survive but have lost the technology to land back on the surface of their world. All Cheela on the surface perish except for four individuals. All succeeding generations of surface Cheela are descended from these four individuals. For a while, the surface Cheela struggle to keep the rudiments of civilization, but eventually a barbarian conqueror arises. The Cheela in space and their human friends watch helplessly as a new dark age ensues. The second half of the story tells the heroic tale of how the space-bound Cheela, with a little help from the humans, eventually are able to land again on the surface, defeat the barbarian tyrant, and start to rebuild Cheela civilization. The first edition cover (shown here) depicts the climactic final battle for the surface as described in the novel.

Worked examples

Example 1 — a first encounter with Starquake (novel)

Start with the simplest possible case. Write down what Starquake (novel) 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 Starquake (novel) 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 Starquake (novel) 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 Starquake (novel)

In research: Starquake (novel) 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 Starquake (novel) 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: Starquake (novel) is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1985 American novels, 1985 English-language novels, 1985 science fiction novels, so understanding it makes those chapters shorter.
In everyday life: Look for Starquake (novel) 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.
