Zhang Juncai

Zhang Juncai 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 Zhang Juncai rather than just read about it. In short: Zhang Juncai (Chinese: 張俊才) is one of the world's tallest people, standing at least 2.42 meters (7 ft 11 in) tall. He is notable for visiting Yao Defen.

Key takeaways

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

Reference excerpt

Zhang Juncai (Chinese: 張俊才) is one of the world's tallest people, standing at least 2.42 meters (7 ft 11 in) tall. He is notable for visiting Yao Defen.

Biography He is from Shanxi Province, China. Zhang was verified as China's tallest man on 23 November 2010 at 2.42 meters (7 ft 11 in). He went to the hospital in April 2009, to visit his friend, the 2.33-meter (7 ft 8 in) tallest living woman Yao Defen.

Worked examples

Example 1 — a first encounter with Zhang Juncai

Start with the simplest possible case. Write down what Zhang Juncai 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 Zhang Juncai 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 Zhang Juncai 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 Zhang Juncai

In research: Zhang Juncai 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 Zhang Juncai 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: Zhang Juncai is common in secondary-school and first-year university syllabi. It links to neighbouring topics Chinese people stubs, Living people, People from Xinzhou, so understanding it makes those chapters shorter.
In everyday life: Look for Zhang Juncai 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.
