Mary C. Lobban

Mary C. Lobban is a astronomy 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 Mary C. Lobban rather than just read about it. In short: Mary Constance Cecile Lobban (1922–1982) was a British physiologist who studied circadian rhythms. Lobban was a Senior Demonstrator in Physiology in the Physiological Laboratory at the University of Cambridge from 1955 to 1959.

Key takeaways

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

Reference excerpt

Mary Constance Cecile Lobban (1922–1982) was a British physiologist who studied circadian rhythms. Lobban was a Senior Demonstrator in Physiology in the Physiological Laboratory at the University of Cambridge from 1955 to 1959. From 1959 to 1974 she worked at the National Institute for Medical Research's Hampstead laboratories. During the Cambridge Physiological Expeditions of the 1950s, Lobban conducted research into the sleep rhythms of volunteers in Spitsbergen, Norway, where the sun does not set during the summer months. Volunteers were separated into two groups and given wristwatches that were set to either 21- or 27-hour days. She later studied the renal circadian rhythms of people living in the Arctic and near the Equator. At the Victoria General Hospital in Halifax, she studied the effects of nurses changing their schedules from 8-hour to 12-hour shifts. In 1978, she became a Professor of Environmental Physiology at Memorial University of Newfoundland where she taught nephrology and human physiology. After suffering a stroke in May 1981, Lobban's health declined. She died on 14 June 1982 in Newfoundland. The Canadian Coast Guard scattered her ashes in the Canadian high Arctic.

Worked examples

Example 1 — a first encounter with Mary C. Lobban

Start with the simplest possible case. Write down what Mary C. Lobban 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 Mary C. Lobban 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 Mary C. Lobban 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 Mary C. Lobban

In research: Mary C. Lobban 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 Mary C. Lobban 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: Mary C. Lobban is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1922 births, 1982 deaths, 20th-century British women biologists, so understanding it makes those chapters shorter.
In everyday life: Look for Mary C. Lobban 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.
