Reference excerpt

The River at the Center of the World: A Journey Up the Yangtze, and Back in Chinese Time is a book by Simon Winchester. It details his travels up the Yangtze river in China and was first published in 1996. Viewing an ancient Chinese painting scroll drawn by Wang Hui gives the author the inspiration on how to structure his book. He starts his journey in Shanghai, at the Yangtze river's delta, and makes his way upriver to the headwaters. Meanwhile, his narration also takes a journey to the past, writing about contemporary times in Shanghai and Nanjing, and discussing events that date back increasingly further in cities upriver. He makes the travel with a companion — a Chinese woman who is referred to in the book only as Lily to protect her identity. The chapter titled A New Great Wall is devoted to the Three Gorges Dam, then under construction and fully operational as of 2012.

Worked examples

Example 1 — a first encounter with The River at the Center of the World

Start with the simplest possible case. Write down what The River at the Center of the World 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 River at the Center of the World 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 River at the Center of the World 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 River at the Center of the World

In research: The River at the Center of the World 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 River at the Center of the World 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 River at the Center of the World is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1996 English-language non-fiction books, 1996 non-fiction books, American travel books, so understanding it makes those chapters shorter.
In everyday life: Look for The River at the Center of the World 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.
