Key takeaways

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

Reference excerpt

Sonali Deraniyagala (born 1964) is a Sri Lankan memoirist and economist. She works as a lecturer in Economics at the SOAS South Asia Institute.

Personal life She was born in Colombo, Sri Lanka, to lawyer (Justin) Edward Pieris Deraniyagala and Gemini Deraniyagala. In 1990, she married economist Stephen Lissenburgh (1964–2004), who "made large contributions to British public policy research". While on vacation at Sri Lanka's Yala National Park in December 2004, she lost her husband, their two sons, her parents, her best friend, and her best friend's mother in the Indian Ocean tsunami. The tsunami carried her two miles inland and she was able to survive by clinging to a tree branch. She reportedly suffered unconsciousness and internal bleeding. Following the tsunami, she was taken to her aunt's house in Colombo. There, she stayed beneath the covers of her cousin’s bed, hoarding sleeping pills for comfort and solace; she attempted to stab herself with a butter knife and smashed her head on the sharp corner of the wooden headboard of the bed in reaction to the trauma of the tsunami. She attempted suicide and also began using alcohol in a bid to forget the tragedy. She went to New York at the end of 2006 to begin a new life after the trauma of the tsunami. Moving to New York, she chose a small apartment in Greenwich Village. She was convinced by her therapist to write down her painful memories to help her relax from the trauma. She started dating the actress Fiona Shaw in 2018 after years of dating men only; the couple got married after she proposed to Shaw a few months later. She considers Joan Didion and Michael Ondaatje her favourite literary heroes.

Career She studied economics at Cambridge University and has a doctorate from the University of Oxford. She is on the faculty of the Department of Economics at SOAS, University of London and is a research scholar at Columbia University in New York City. She lives in New York City, and London. After surviving the tsunami, Deraniyagala relocated to New York where she became a visiting research scholar at Columbia University. Her 2013 memoir, Wave, recounts her experiences in the tsunami and the progression of her grief in the ensuing years. Sonali began writing her memoir Wave in 2010, where she describes her personal experiences in the aftermath of the tsunami and how she coped with it. The book became an instant hit and much to Sonali's surprise, it became one of the most sought-after memoirs globally. It was shortlisted for the 2013 National Book Critics Circle Award (Autobiography) and won the PEN Ackerley Prize 2013. This book is currently used as a prose passage in the education system (O/Level) for English Literature in Sri Lanka. She has also expressed her concerns, insights and opinions about the 2019–present Sri Lankan economic crisis to various platforms.

Worked examples

Example 1 — a first encounter with Sonali Deraniyagala

Start with the simplest possible case. Write down what Sonali Deraniyagala 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 Sonali Deraniyagala 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 Sonali Deraniyagala 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 Sonali Deraniyagala

In research
Sonali Deraniyagala 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 Sonali Deraniyagala 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
Sonali Deraniyagala is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1964 births, 20th-century Sri Lankan LGBTQ people, 20th-century Sri Lankan women writers, so understanding it makes those chapters shorter.
In everyday life
Look for Sonali Deraniyagala 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.
