Reference excerpt

Marion P. McCrane (1931–2013) was an American zoologist and educator. She was a traveling lecturer for the New York Zoological Park and in the 1950s she lectured to over 30,000 school children a year in the New York City area. She referred to herself as the "Zoo Lady" when speaking to school and wanted to stimulate children's interest in zoology. McCrane later became the head of the Information and Education Division at the National Zoological Park in Washington, D.C., from 1962 through December 1968. During this time, she focused particular on caring for baby animals. In 1964, she found a newborn two-toed sloth abandoned in a zoo enclosure and took it to the zoo hospital to nurse it to health. She ended up caring for the baby sloth for more than eight months, the first known example of a person successfully hand rearing a two-toed sloth. McCrane rigorously documented her experience as well as her observations for the benefit of science. The study that came out of her experience was titled "Behavior and Development of a Hand-Reared Two-Toed Sloth (choloepus didactylus)" and published in International Zoo Yearbook, Volume 6, London Zoological Society. McCrane was a member of the Anteaters Association. In addition to her work in the US, in 1965, McCrane brought a pygmy hippopotamus and four white-tailed deer to the National Zoological Gardens in Pretoria, South Africa as part of an animal exchange. McCrane returned to the US with two aardwolves, a serval, caracal, black-footed cats, flightless rails, a Meyer's parrot, and Cape parrot.

Worked examples

Example 1 — a first encounter with Marion P. McCrane

Start with the simplest possible case. Write down what Marion P. McCrane 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 Marion P. McCrane 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 Marion P. McCrane 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 Marion P. McCrane

In research: Marion P. McCrane 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 Marion P. McCrane 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: Marion P. McCrane is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1931 births, 2013 deaths, American zoologists, so understanding it makes those chapters shorter.
In everyday life: Look for Marion P. McCrane 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.
