Reference excerpt

May Ratnayeke (1892–1988) was a Sri Lankan physician, is known for being the second female medical student from that country and its first female doctor.

Life Dr. Ratnayeke was born May de Livera to John de Livera, one of six siblings, in Kandy. In her childhood, she attended local schools, then went on to medical school at Ceylon Medical College in Colombo. She graduated with her MD in 1916. After obtaining her degree, she worked at the American Mission Hospital in Jaffna, then moved to Lady Havelock Hospital. She was a fellow at the Royal Free Hospital for Women from 1925 to 1927. Dr Ratnayeke was married in 1927 and had three children, a son and a daughter who became physicians, and a son who became a tea planter. In 1927 she became a surgeon at Lady Havelock Hospital. She was a fellow at the University of Edinburgh Medical School for a year from 1932 to 1933. After her fellowship, she was promoted to chief surgeon, and joined the faculty at the medical school of the University of Ceylon. In the 1930s Dr Ratnayeke contributed articles on gynaecological issues to a number of international journals. In 1943 she was elected President of the Ceylon Branch of the British Medical Association. For most of her career, she was part of the Medical Women's International Association.

Worked examples

Example 1 — a first encounter with May Ratnayake

Start with the simplest possible case. Write down what May Ratnayake 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 May Ratnayake 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 May Ratnayake 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 May Ratnayake

In research: May Ratnayake 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 May Ratnayake 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: May Ratnayake is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1892 births, 1988 deaths, Alumni of the University of Edinburgh, so understanding it makes those chapters shorter.
In everyday life: Look for May Ratnayake 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.
