Reference excerpt

Wen Li is a space physicist at Boston University. Her research interests include space plasma waves, Earth's radiation belt physics, solar-wind magnetosphere coupling, energetic particle precipitation, and the Jovian magnetosphere and aurora. She is a Fellow of the American Geophysical Union.

Biography Wen Li received a B.Sc. in Geophysics from the University of Science and Technology of China in 2005. She earned an M.S. and Ph.D. in Atmospheric and Oceanic Sciences from the University of California, Los Angeles in 2007 and 2010, respectively. Following her Ph.D., she remained at the University of California, Los Angeles as an associate researcher until 2016, when she moved to Boston University. Li's research focuses on waves in Earth's magnetosphere, modeling Earth's radiation belts, and examining radiation belts on Jupiter. In 2019, she received funding to examine plasma waves called 'whistler mode waves', which are high-energy electrons in Earth's radiation belts.

Research One of Li's research areas concerns "killer electrons," electrons that emit a high level of radiation that can damage satellites in Earth's radiation belts. Li uses multi-satellite observations to study this process, which has implications for national security and commercial interests. Her research and use of low-altitude satellite data has revealed that electromagnetic ion cyclotron waves during geomagnetic storms and recovery cause the loss of relativistic electrons that would typically be trapped in Earth's radiation belts. To understand the distribution of these plasma waves, Li used low-satellite data to calculate plasma wave properties and create a more detailed global distribution than previously available. These findings have since been incorporated into numerous other research projects and studies.

Worked examples

Example 1 — a first encounter with Wen Li (space physicist)

Start with the simplest possible case. Write down what Wen Li (space physicist) claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, 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 Wen Li (space physicist) 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 Wen Li (space physicist) 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 Wen Li (space physicist)

In research: Wen Li (space physicist) appears in physics 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 Wen Li (space physicist) 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: Wen Li (space physicist) is common in secondary-school and first-year university syllabi. It links to neighbouring topics 21st-century American women scientists, 21st-century Chinese physicists, American physicist stubs, so understanding it makes those chapters shorter.
In everyday life: Look for Wen Li (space physicist) 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.
