Lo Wing-lok

Lo Wing-lok is a astronomy 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 Lo Wing-lok rather than just read about it. In short: Lo Wing-lok, JP (Chinese: 勞永樂; 13 September 1954 – 9 May 2015) was a Hong Kong doctor and politician. He was the Legislative Councillor for the Medical functional constituency from 2000 to 2004.

Key takeaways

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

Reference excerpt

Lo Wing-lok, JP (Chinese: 勞永樂; 13 September 1954 – 9 May 2015) was a Hong Kong doctor and politician. He was the Legislative Councillor for the Medical functional constituency from 2000 to 2004. He was the vice-chairman of the pro-democracy League of Social Democrats but quit the party in late 2007. He ran for the Legislative Council again in 2004, 2008 and 2012 but was not elected. He died from lung cancer in 2015.

Biography Lo was born in Hong Kong in 1954 and lived in the Healthy Village, a public housing estate in North Point. He graduated from St Paul's College in 1974 and from the Faculty of Medicine of the University of Hong Kong in 1979. He was an infectious disease specialist. He entered into politics when he was elected to the Election Committee in the 1998 Subsector elections through the Medical sub-sector. He was elected to the Legislative Council of Hong Kong (Legco), representing the Medical functional constituency in 2000 Legco election. Lo was chairman of the Panel on Health Services of the Legislative Council from 2002 to 2003. He belonged to the pro-government parliamentary group Breakfast Group. During the controversies over Article 23 legislation, he publicly supported the national security law. He failed to retain the seat in the 2004 election won by urologist Kwok Ka-ki. During serving on the Legislative Council, he was also president of the Hong Kong Medical Association for two terms from 2002 to 2004. Lo made a surprise move when he joined the newly founded pro-democracy League of Social Democrats in 2006 as vice-chairman, but resigned from the position and quit the party in late December 2007 over differences with the chairman Wong Yuk-man on the lease of the party's headquarters. In 2007, he bid to represent the pan-democracy camp in the important Legco by-election for Hong Kong Island but was defeated in the primary by the eventual winner of the seat, Anson Chan. Lo stood for the Hong Kong Island constituency in the 2008 and 2012 Legco elections as an independent candidate but was not returned.

Personal life He married his schoolmate, gynaecologist Anna Yung Hiu-yan, who died in 2013. They had a son, Alasdair Kai-yan Lo.

Death He battled lung cancer during his last years of his life. He was admitted to Queen Mary Hospital in May 2015 and then discharged, but died at Canossa Hospital the morning of 9 May.

Worked examples

Example 1 — a first encounter with Lo Wing-lok

Start with the simplest possible case. Write down what Lo Wing-lok claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, 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 Lo Wing-lok 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 Lo Wing-lok 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 Lo Wing-lok

In research: Lo Wing-lok appears in astronomy 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 Lo Wing-lok 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: Lo Wing-lok is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1954 births, 2015 deaths, Alumni of St. Paul's College, Hong Kong, so understanding it makes those chapters shorter.
In everyday life: Look for Lo Wing-lok 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.
