Reference excerpt

Ruth Starrett McGuire (née Colvin; February 19, 1893 – September 2, 1950) was an American plant pathologist. She studied sugar cane diseases and sugarbeets.

Early life and education Ruth Colvin was born in 1893. She earned her B.A. in 1914 and her M.A. in 1916, both from Indiana University Bloomington. After earning her Master's, she worked as a high school teacher for three years. She never earned her Ph.D. but she took classes at numerous other schools including George Washington University, Northwestern University, and the University of Maryland. She was married to Francis Brenton Starrett (in 1925), and secondly, to Charles McGuire (in 1940).

Career McGuire started work at the United States Department of Agriculture. She retired with the title of Associate Cytologist. She did not stop working after retirement. She served as a research associate at the California Academy of Sciences from 1931 until 1942. While there, she studied the relationships between birds and insects. She also studied sugarcane, sugarbeets, bees, silkworms, beetles and mosquitoes. McGuire was a member of the Botanical Society of Washington, the Entomological Society of America, and the International Society of Sugar Cane Technologists.

Death A native of Flora, Indiana, McGuire died in 1950, aged 57, at a hospital in Silver Spring, Maryland, from undisclosed causes; she was survived by her husband and her brother. She is buried at Arlington National Cemetery.

Worked examples

Example 1 — a first encounter with Ruth C. McGuire

Start with the simplest possible case. Write down what Ruth C. McGuire 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 Ruth C. McGuire 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 Ruth C. McGuire 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 Ruth C. McGuire

In research: Ruth C. McGuire 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 Ruth C. McGuire 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: Ruth C. McGuire is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1893 births, 1950 deaths, 20th-century American agronomists, so understanding it makes those chapters shorter.
In everyday life: Look for Ruth C. McGuire 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.
