Reference excerpt

Grace Rajamalar Barr–Kumarakulasinghe (née Sinnathamby; 7 August 1908 - 26 April 2013) was a paediatrician from Sri Lanka.

Biography Barr-Kumarakulasinghe was the seventh child of G.V. and Alice Sinnathamby. She attended Wolfendhal Girls' School, followed by Good Shepherd Convent Kotahena. She graduated from Ladies' College and originally intended to study English literature, however her brother, G. S. Sinnathamby, encouraged her to study medicine. She studied at Colombo Medical College and qualified as a doctor in 1937. In 1948, she went to the United Kingdom and completed postgraduate studies in Edinburgh and London, returning to Sri Lanka in 1953. During her career, she worked as a doctor at Lady Ridgeway Hospital, De Soysa Maternity Hospital and Castle Street Hospital for Women in Colombo. Barr-Kumarakulasinghe was the first paediatrician in Sri Lanka to record morbidity and mortality of newborns, and gave lectures on this topic to local medical associations. She served as president of the Sri Lanka Paediatric Association and was founding joint editor of the medical journal Ceylon Journal of Obstetrics and Gynaecology.

Personal life In 1927, Sinnathamby married Gunaratnam Barr-Kumarakulasinghe, a lawyer. The couple had a son in 1948.

Worked examples

Example 1 — a first encounter with Grace Barr-Kumarakulasinghe

Start with the simplest possible case. Write down what Grace Barr-Kumarakulasinghe claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, 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 Grace Barr-Kumarakulasinghe 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 Grace Barr-Kumarakulasinghe 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 Grace Barr-Kumarakulasinghe

In research: Grace Barr-Kumarakulasinghe appears in science 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 Grace Barr-Kumarakulasinghe 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: Grace Barr-Kumarakulasinghe is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1908 births, 2013 deaths, Asian medical biography stubs, so understanding it makes those chapters shorter.
In everyday life: Look for Grace Barr-Kumarakulasinghe 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.
