Margaret di Menna

Margaret di Menna is a biology topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Margaret di Menna rather than just read about it. In short: Margaret Elaine di Menna (8 July 1923 – 24 March 2014) was a New Zealand microbiologist. In 1954 she became the first woman to gain a Doctor of Philosophy degree from a New Zealand university.

Key takeaways

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

Reference excerpt

Margaret Elaine di Menna (8 July 1923 – 24 March 2014) was a New Zealand microbiologist. In 1954 she became the first woman to gain a Doctor of Philosophy degree from a New Zealand university. Her doctoral thesis at the University of Otago was entitled Yeasts of the human body, their nature and relationship. She had previously graduated with a MSc(Hons) from the same institution in 1948. In 1990, di Menna was awarded the New Zealand 1990 Commemoration Medal, and in the 1997 New Year Honours, she was appointed an Officer of the New Zealand Order of Merit, for services to microbiology. In 2011, the reading room at Abbey College at the University of Otago was named in her honour. She was a prominent member of Zonta International. She died in Hamilton in 2014.

Worked examples

Example 1 — a first encounter with Margaret di Menna

Start with the simplest possible case. Write down what Margaret di Menna claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, 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 Margaret di Menna 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 Margaret di Menna 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 Margaret di Menna

In research: Margaret di Menna appears in biology 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 Margaret di Menna 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: Margaret di Menna is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1923 births, 2014 deaths, 20th-century New Zealand women scientists, so understanding it makes those chapters shorter.
In everyday life: Look for Margaret di Menna 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.
