Jack Hui

Jack Hui is a mathematics 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 Jack Hui rather than just read about it. In short: Jack Hui (Chinese: 許子岳; born 1988) is an alumnus from Queen's College in Hong Kong. He is considered a prominent student because of the outstanding performance in International Mathematical Olympiad (IMO) and various national and regional mathematics competitions.

Key takeaways

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

Reference excerpt

Jack Hui (Chinese: 許子岳; born 1988) is an alumnus from Queen's College in Hong Kong. He is considered a prominent student because of the outstanding performance in International Mathematical Olympiad (IMO) and various national and regional mathematics competitions. Though accused of sexually assaulting an airline hostess, he was later found not guilty, and was admitted to the Faculty of Mathematics of Peking University.

Maths awards Hui's talent in mathematics won him many medals and awards in different competitions. In 2003, he participated in the Asia Inter-cities Teenagers Mathematics Invitation Competition, which was held in Fuzhou, Fujian, China, representing Hong Kong. His team won the junior secondary team and group event. He was successful in science competition too, winning the first class award in the individual event in the Hong Kong Physics Olympiad 2004. In 2005, besides winning a bronze medal in China Mathematics Olympiad (CMO), he was successful in the 46th International Mathematical Olympiad (IMO) in Mérida, Mexico, capturing a silver medal. In 2006, he claimed the bronze medal again in the China Mathematics Olympiad (CMO). In March, he won another bronze in the Asian Pacific Mathematics Olympiad (APMO) 2006. Finally, he won another silver medal in the 2006 IMO, this time in Ljubljana, Slovenia.

Worked examples

Example 1 — a first encounter with Jack Hui

Start with the simplest possible case. Write down what Jack Hui claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In mathematics, 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 Jack Hui 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 Jack Hui 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 Jack Hui

In research: Jack Hui appears in mathematics 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 Jack Hui 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: Jack Hui is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1988 births, 21st-century mathematicians, Academic staff of Peking University, so understanding it makes those chapters shorter.
In everyday life: Look for Jack Hui 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.
