The Risen Empire 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 The Risen Empire rather than just read about it. In short: The Risen Empire is a science fiction novel by American writer Scott Westerfeld. Setting and plot The novel is set in an undefined distant future (although it is implied to exist roughly 5,000 years from now), in which there is a galactic empire spanning eighty worlds, amongst other human civilizations.

Key takeaways

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

Reference excerpt

The Risen Empire is a science fiction novel by American writer Scott Westerfeld.

Setting and plot The novel is set in an undefined distant future (although it is implied to exist roughly 5,000 years from now), in which there is a galactic empire spanning eighty worlds, amongst other human civilizations. The empire is ruled by the Risen Emperor, who has discovered the secret of immortality through means of a symbiont (spelled "symbiant" in the novel). Immortality is conferred on favored Imperial citizens, referred to as the 'grays'. The life of the 'grays' is governed by strict ritual and a form of worship towards the Emperor, including long pilgrimages in his honor. To create balance, the living citizens of the Empire are represented by an elected Imperial Senate, and by elected governments on each world. Another prominent group within the Empire includes the Plague Axis, a group that deliberately leave themselves vulnerable to disease to preserve human genetic diversity. Faster than light travel is impossible (although FTL communication via quantum entanglement is used), and the result of more mundane interstellar travel between the eighty worlds of the empire results in relativistic effects due to the high speeds involved; as such, the ages of space travelers become out of sync with those of their friends and family, an effect known as the "Time Thief". Other parties in the Empire, such as the Imperial Senate, are also subject to the "Time Thief" due to the use of cryogenic freezing. The Empire, protected by the Imperial Navy, is at war with a cult of fanatical cyborgs known as the Rix, who worship compound artificial intelligences. These emergent intelligences arise from sufficiently interconnected computer networks, ranging from public communications to traffic lights to classified government computers. The central characters are Captain Laurent Zai of the Imperial Navy, and Senator Nara Oxham, a member of the Secularist Party, which opposes worship of the Emperor and the use of the symbiont to create immortality. Despite their political differences, the two become lovers. Zai is sent away to fight the Rix; due to the death of the Emperor's sister at the hands of the Rix, Zai is expected to commit ritual suicide to mark his failure, but chooses not to do so. Senator Oxham, appointed to the Emperor's War Council, opposes unpalatable war plans that would lead to the sacrifice of billions of Imperial citizens in order to preserve state secrets contained in the compound intelligences. The storyline is continued in The Killing of Worlds, released in 2003.

Reception Publishers Weekly called it "exceptionally smart and empathetic", and noted that Westerfeld "keep(s) the reader constantly off-balance". Kirkus Reviews was less positive, faulting the book for having "horrendously slow" flashback sequences and judging the book as a whole to be "an exposition-heavy introduction to a sequel" (while conceding that it was "sprightly" and had "breathless action sequences"). SF Signal considered it an "excellent example of space opera", with "strong characters" and "lots of cool technology", but criticized Westerfeld for excessive portrayal of politics. John Clute described it as "considerably better than good", and praised Westerfeld for providing "some of the neatest, most kinetically exact, clearest-written hi-tech action (Clute has) come across".

Worked examples

Example 1 — a first encounter with The Risen Empire

Start with the simplest possible case. Write down what The Risen Empire 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 Risen Empire 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 Risen Empire 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 Risen Empire

In research: The Risen Empire 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 Risen Empire 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 Risen Empire is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2003 American novels, 2003 English-language novels, 2003 science fiction novels, so understanding it makes those chapters shorter.
In everyday life: Look for The Risen Empire 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.
