Xu Guoliang

Xu Guoliang 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 Xu Guoliang rather than just read about it. In short: Xu Guoliang (Chinese: 徐国良; born February 1965) is a Chinese molecular geneticist. He is a professor at the Shanghai Institute of Biochemistry and Cell Biology and an academician of the Chinese Academy of Sciences.

Key takeaways

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

Reference excerpt

Xu Guoliang (Chinese: 徐国良; born February 1965) is a Chinese molecular geneticist. He is a professor at the Shanghai Institute of Biochemistry and Cell Biology and an academician of the Chinese Academy of Sciences.

Biography Xu graduated from Hangzhou University Department of Biology in 1985, and obtained his master's degree at Institute of Genetics and Developmental Biology, Chinese Academy of Sciences in 1989. In 1993 he earned his Ph.D. from Max Planck Institute for Molecular Genetics and Technische Universität Berlin. Xu's research mainly focuses on the epigenetic regulation. In 2011 his group discovered that the DNA oxidative demethylation is mediated by DNA oxidase TET and glycosidase TDG, and clarified its role in the canceration of the cells. In 2014, he published his study concerning the effect of DNA methylation and histone modification. In 2013, Xu was awarded the TWAS Prize "for his contribution to the understanding of the role and mechanism of DNA oxidation in epigenetic regulation of mammalian development". He won the Tan Kah Kee award in 2014. In 2015, he was elected a member of the Chinese Academy of Sciences.

Worked examples

Example 1 — a first encounter with Xu Guoliang

Start with the simplest possible case. Write down what Xu Guoliang 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 Xu Guoliang 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 Xu Guoliang 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 Xu Guoliang

In research: Xu Guoliang 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 Xu Guoliang 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: Xu Guoliang is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1965 births, Biologists from Zhejiang, Chinese geneticists, so understanding it makes those chapters shorter.
In everyday life: Look for Xu Guoliang 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.
