John M. MacDougal

John M. MacDougal 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 John M. MacDougal rather than just read about it. In short: John Mochrie MacDougal (born 1954) is an American botanist, noted for his work on the taxonomy of passion flowers, having discovered several new species. He earned his Bachelor of Science in 1975 at College of Charleston.

Key takeaways

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

Reference excerpt

John Mochrie MacDougal (born 1954) is an American botanist, noted for his work on the taxonomy of passion flowers, having discovered several new species. He earned his Bachelor of Science in 1975 at College of Charleston. In 1984 he earned his doctorate at Duke University. Between 1984 and 1986 he was visiting assistant professor of biology at the North Carolina Agricultural and Technical State University. Between 1987 and 1989 he was postdoctoral researcher at the Flora Mesoamerica project at the Missouri Botanical Garden in St. Louis, Missouri. Between 1990 and 2002 he was conservatory manager at the Missouri Botanical Garden. MacDougal has written more than fifty peer reviewed articles and book chapters. Currently, he is an assistant professor of biology at Harris–Stowe State University. James Mallet and Sandra Knapp have named Passiflora macdougaliana after him.

Worked examples

Example 1 — a first encounter with John M. MacDougal

Start with the simplest possible case. Write down what John M. MacDougal 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 John M. MacDougal 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 John M. MacDougal 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 John M. MacDougal

In research: John M. MacDougal 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 John M. MacDougal 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: John M. MacDougal is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1954 births, 21st-century American botanists, American botanist stubs, so understanding it makes those chapters shorter.
In everyday life: Look for John M. MacDougal 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.
