Kwok Ka-ki

Kwok Ka-ki 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 Kwok Ka-ki rather than just read about it. In short: Kwok Ka-ki (Chinese: 郭家麒; born 20 July 1961) is a Hong Kong former politician. He is a private urology doctor, having graduated from the Faculty of Medicine at the University of Hong Kong.

Key takeaways

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

Reference excerpt

Kwok Ka-ki (Chinese: 郭家麒; born 20 July 1961) is a Hong Kong former politician. He is a private urology doctor, having graduated from the Faculty of Medicine at the University of Hong Kong. Kwok is a member of the Civic Party, having joined on 19 July 2010. On 11 November 2020, he was disqualified from the Legislative Council, along with three other lawmakers of the pan-democratic camp, by the central government in Beijing on request of the Hong Kong government. A mass resignation of pan-democrats the same day left the Legislative Council without a substantial opposition.

Early life and education Kwok has family roots in Jieyang, Guangdong. He graduated in 1985 from the Faculty of Medicine at the University of Hong Kong. After graduation, he worked as a private urology doctor.

Political career Kwok Ka-ki served three terms in the Legislative Council. From 2004 to 2008 he served as a member for the Medical functional constituency, losing in the 2008 Hong Kong legislative election to Leung Ka-lau. From 2012 to 2020, Kwok served as a member of the Legislative Council for New Territories West. From 1994 until 2007, Kwok was a member of the Central and Western District Council, representing Mid Levels East.

Opposition to renaming of the HKU Faculty of Medicine On 23 May 2005, Kwok participated in a press conference of University of Hong Kong alumni who protested the renaming of the university's Faculty of Medicine as Li Ka Shing Faculty of Medicine. The renaming was to honour a donation of 128 million US dollars to the faculty by business tycoon and philanthropist Li Ka-shing. In an interview at that time, Kwok complained about the lack of transparent process prior to the decision.

Condemnation of police during the 2019–2020 Hong Kong protests During the 2019–2020 Hong Kong protests, Kwok lambasted the police strategy during the 2019 Prince Edward station attack of 31 August 2019, which allegedly hindered first aiders from entering the station to treat the wounded, as a "behaviour unbefitting of monsters".

Criticism of government COVID-19 measures On 28 April 2020, Food and Health Secretary Sophia Chan announced that due to the easing of the COVID-19 pandemic, entry restrictions from the mainland that had been imposed earlier in the pandemic would be scrapped for students, teachers and people with business activities "beneficial to Hong Kong". Kwok sharply criticized this decision, saying that the risk of imported COVID-19 cases from mainland China was still great, and likening the step to "inviting a wolf into your home". In October 2020, Kwok criticized the plan of the Hong Kong government to introduce mandatory COVID-19 testing for patients with symptoms, saying that making tests mandatory would breach the medical code of practice, could possibly be counterproductive due to those who did not want to be tested not seeking medical attention, and be a waste of government resources as symptoms such as headaches were also common in diseases other than COVID-19. He also slammed the government's easing of social distancing measures for local tour groups and wedding ceremonies to a respective limit of 30 and 50 people respectively, alleging that the continuing four-person gathering limit had remained in place in order to suppress public demonstrations.

Political disqualification Five weeks ahead of the (subsequently postponed) 2020 Hong Kong Legislative Council Election, on 30 July 2020, as Kwok prepared to defend his seat, the government stated that he was among a dozen pro-democracy candidates whose nominations were 'invalid', under an opaque process in which, nominally, civil servants – returning officers – assess whether, for instance, a candidate had objected to the enactment of the national security law, or was sincere in statements made disavowing separatism. On 11 November 2020, following a decision of the Standing Committee of the National People's Congress he was disqualified from Legislative Council along with three other lawmakers; this resulted in the resignation of a further 15 pro-democracy lawmakers.

Professional disqualification Kwok Ka-ki, having completed his sentence for violating the National Security Law, was permanently removed from the medical register by the Medical Council on April 16, 2026, one year after his release. This was the first disciplinary hearing for a registered doctor convicted of a national security offense. The inquiry panel stated that Kwok Ka-ki's blatant violation of the National Security Law as a doctor affected public confidence in the medical profession, thus barring him from practicing in Hong Kong. This case, the first to be investigated for a doctor involved in a national security legal case, sets a precedent.

Arrest and withdrawal from politics On 6 January 2021, Kwok was among 53 members of the pro-democratic camp who were arrested under the national security law, specifically its provision regarding alleged subversion. The group stood accused of the organisation of and participation in unofficial primary elections held by the camp in July 2020. Kwok was released on bail on 7 January, a decision that was overturned by a higher court on 13 March. During the bail hearings, Kwok resigned from the Civic Party and later announced his decision to leave politics, also penning an open letter together with Alvin Yeung, Jeremy Tam and Lee Yue-shun, publicized on 15 April, which called for the party to disband.

Personal life On 15 July 2017, Kwok was denied entry to Macau, with authorities citing as reason his being a threat to internal security. Kwok called the decision "extremely ridiculous" and asked Chief Executive Carrie Lam to request an explanation from Macau authorities.

Worked examples

Example 1 — a first encounter with Kwok Ka-ki

Start with the simplest possible case. Write down what Kwok Ka-ki 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 Kwok Ka-ki 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 Kwok Ka-ki 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 Kwok Ka-ki

In research
Kwok Ka-ki 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 Kwok Ka-ki 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
Kwok Ka-ki is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1961 births, Alumni of the University of Hong Kong, Civic Party politicians, so understanding it makes those chapters shorter.
In everyday life
Look for Kwok Ka-ki 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.
