Liu Yan (scientist)

Liu Yan (scientist) 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 Liu Yan (scientist) rather than just read about it. In short: Liu Yan (Chinese: 刘岩) is a Chinese Antarctic researcher best known for her work on iceberg calving. She is an associate professor of geography in the College of Global Change and Earth System Science (GCESS) and Polar Research Institute, Beijing Normal University.

Key takeaways

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

Reference excerpt

Liu Yan (Chinese: 刘岩) is a Chinese Antarctic researcher best known for her work on iceberg calving. She is an associate professor of geography in the College of Global Change and Earth System Science (GCESS) and Polar Research Institute, Beijing Normal University.

Early life and education Liu received her B.Sc., as an outstanding graduate, in photogrammetry and remote sensing from Wuhan University in 2003, her M.Sc. in cartography and geographical information system from the Institute of Remote Sensing Application, Chinese Academy of Sciences in 2006, and her Ph.D. in global environmental change from Beijing Normal University in 2013. She carried out post-doctoral research work at the GCESS between 2013 and 2015 and took charge of NSFC project: Mass balance and its change of Antarctic ice shelves in 2014.

Career and impact Liu began her Antarctic research in 2009 after working as a technical manager in the field of remote sensing applications for three years. Her research focuses on ice shelves in Antarctica and their responses to climate change. She uses a combination of satellite radar and altimetry and other remote sensed data to understand ice shelf dynamic processes. She is known for high impact research into Antarctic ice shelf mass loss, especially iceberg calving and basal melting. She published the dataset of Antarctic iceberg calving in Chinese National Arctic and Antarctic Data Center. Liu is one of core members of Xiao Cheng's polar remote sensing research group at Beijing Normal University. This group has used remote sensed data to contribution extensively to Antarctic land cover mapping and to provide the monitoring and supporting for navigation of Xue Long icebreaker in the Chinese Antarctic expeditions since 2011. They provided the efficient data for XUELONG icebreaker successfully getting out of the trouble after Antarctica rescue in January 2014. Liu's work on iceberg calving and ice shelf retreat in Antarctica used satellite images to measure all icebergs larger than 1 km2 calving from the entire Antarctic coastline, and the state of health of all the ice shelves. Some large ice shelves are growing while many smaller ice shelves are shrinking. They found high rates of iceberg calving from Antarctic ice shelves that are undergoing basal melt-induced thinning, which suggests the fate of ice shelves may be more sensitive to ocean forcing than was previously thought.

Worked examples

Example 1 — a first encounter with Liu Yan (scientist)

Start with the simplest possible case. Write down what Liu Yan (scientist) 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 Liu Yan (scientist) 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 Liu Yan (scientist) 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 Liu Yan (scientist)

In research: Liu Yan (scientist) 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 Liu Yan (scientist) 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: Liu Yan (scientist) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Academic staff of Beijing Normal University, Beijing Normal University alumni, Chinese Antarctic scientists, so understanding it makes those chapters shorter.
In everyday life: Look for Liu Yan (scientist) 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.
