About me

I grew up in Colchester, where I attended Colchester Royal Grammar School. I am British Chinese; most of my family lives in Hong Kong.

I was a PhD student at DAMTP, University of Cambridge, where I studied granular mechanics, and the applicability of boundary layer theory to granular flows. Ask me more! I'm an alumnx of Queens' College, Cambridge.

In daily life I use the pronoun they. I use she in some communities, and he for historical reasons.

Interests and editing style

I'm particularly interested in mathematics, especially fluid dynamics and granular mechanics. I'm also interested in Chinese history and Chinese culture, as well as East Asian culture more generally.

I support the Plain English Campaign. Plain English is a writing style which aims for 'clarity, brevity, and the avoidance of technical language'. Among other things, Plain English prefers simple sentence structures, avoids using the passive voice, and avoids inappropriate jargon, formal language (especially euphemisms – see WP:CENSOR), and clichés. I often edit articles to rephrase paragraphs which are unclear, or remove words which don't contribute any meaning. Please let me know if such an edit inappropriately changes a sentence's meaning.

Here are some of the articles that I have created, edited substantially, or (if red link) intend to create. It's often said that people here live inside the Cambridge bubble, so if my ideas of notability are misguided, please let me know.

General mathematics

• Riemann's differential equation

Stability theory

My essay for Part III was on the stability of shear flows: particularly, stability analysis using global modes. The following articles are relevant, and I have created or edited some of these articles.

• Global mode
• Normal mode
• Squire's theorem
• Stability theory
• Briggs–Bers technique

Finite element analysis

• Finite element method
• FreeFem++

Fluid dynamics

• Fluid dynamics
• Shallow water equations
• Shear flow
• Kapitza instability (and roll wave, which redirects)

Granular mechanics

• Inertial number
• μ(I) rheology
• Bagnold's fluid

Biographical

• Philip Drazin
• Stuart Dalziel
• Patrick Huerre – see also User:Stephaniehuerre/sandbox
• Feng Kang
• Grae Worster
• Institute of Theoretical Geophysics

Chinese culture and philosophy

• Draft:Jiangjun (rank)
• Jizhou (ancient China)
• Ren (Confucianism)

Hong Kong

• Below the Lion Rock
• Below the Lion Rock (song) -- expanding article by translating the corresponding page on Chinese Wikipedia
