Reference excerpt

Harriet Redfield Cobb (September 10, 1866 – February 13, 1958) was an American mathematics educator, a professor at Smith College from 1895 to 1931.

Early life and education Cobb was born in Peekskill, New York, the daughter of Elisha G. Cobb and Esther Meroa Redfield Cobb. Her father was a Congregational clergyman. She attended Northampton High School and earned a bachelor's degree in mathematics at Smith College in 1889, and an honorary master's degree, also from Smith College, in 1891. She pursued further studies at Columbia University.

Career Cobb taught mathematics at schools in Louisiana and Ohio before returning to Smith as a mathematics instructor in 1895. She taught geometry at Smith College until she retired as professor emerita in 1931. Her colleagues at Smith included fellow mathematics professors Eleanor P. Cushing. Ruth Goulding Wood, and Suzan Rose Benedict. She was a member of Phi Beta Kappa and a president of the Western Massachusetts Mathematics Association. She also taught Bible study classes at a Congregational church. Cobb was a busy traveler. She made an eight-month trip around the world with her friend, Pennsylvania math educator Sarah Gilbert, in 1907 and 1908. She traveled to China several times in the 1920s, and consulted there on math education for Chinese women. Cobb spent much of her retirement in Florida. She was active in Smith alumnae activities there. In 1936 she spoke to an audience of retired teachers in Florida about "The Pioneer Spirit of Smith College".

Personal life Cobb died in 1958, aged 91 years, in Northampton, Massachusetts.

Worked examples

Example 1 — a first encounter with Harriet Redfield Cobb

Start with the simplest possible case. Write down what Harriet Redfield Cobb claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In mathematics, 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 Harriet Redfield Cobb 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 Harriet Redfield Cobb 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 Harriet Redfield Cobb

In research: Harriet Redfield Cobb appears in mathematics 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 Harriet Redfield Cobb 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: Harriet Redfield Cobb is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1866 births, 1958 deaths, American mathematics educators, so understanding it makes those chapters shorter.
In everyday life: Look for Harriet Redfield Cobb 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.
