Soban

Soban 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 Soban rather than just read about it. In short: Soban (Korean: 소반; Hanja: 小盤) are small tray-like tables, usually wooden, used in Korea for carrying food and as individual dining tables. They are generally made of walnut, pine or ginko wood, often sourced from the carpenter's local area.

Key takeaways

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

Reference excerpt

Soban (Korean: 소반; Hanja: 小盤) are small tray-like tables, usually wooden, used in Korea for carrying food and as individual dining tables. They are generally made of walnut, pine or ginko wood, often sourced from the carpenter's local area. Carvings and murals showing images of soban have been found in tombs dating back to the time of the Goguryeo kingdom. As well as being used for dining, soban were also used for general carrying tasks, as writing desks and as small altars for prayers or for burning incense. Soban are generally fairly small, due to the historical custom of family members and guests each having their own individual table. The standard dimensions are around 30 by 50 cm (12 by 20 in), with the legs standing about 30 cm (12 in) high. The table is placed on the floor, and used from a seated position.

The art of making soban, called sobanjang, is designated one of Korea's Important Intangible Cultural Properties, and was sufficiently important in the past for it to have been a state-sponsored profession. Soban are generally classified in various ways. Commonly they are referred to by their region of origin. Another standard system classifies them by the shape and number of the legs, the most popular of which is hojokban ("tiger leg"). The shape of the table's surface (rectangular, circular, octagonal etc.) is also used to differentiate them.

Worked examples

Example 1 — a first encounter with Soban

Start with the simplest possible case. Write down what Soban 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 Soban 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 Soban 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 Soban

In research: Soban 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 Soban 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: Soban is common in secondary-school and first-year university syllabi. It links to neighbouring topics Furniture, National Intangible Cultural Heritage of South Korea, Tables (furniture), so understanding it makes those chapters shorter.
In everyday life: Look for Soban 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.

Frequently asked questions

What is Soban in simple terms?

Why does Soban matter?

Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Soban?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
