Reference excerpt

Marjorie Williams (1900–1983) was an American astronomer who worked for many years as a professor at Smith College. Her research involved the observation of variable stars, and she served as president of the American Association of Variable Star Observers. She also wrote about a theory of Johannes Kepler according to which the Star of Bethlehem was a triple planetary conjunction.

Early life and education Williams was born on October 12, 1900, in Marshalltown, Iowa, where her father was a Quaker minister. After graduating from Guilford College, a Quaker college in North Carolina, she continued for graduate study at Smith College and the University of Michigan, where she earned a master's degree and doctorate respectively.

Academic career She joined the Smith College faculty in 1925 as an instructor, progressing through the faculty ranks over 28 years at Smith as assistant, associate, and full professor, chairman of the astronomy department, and director of the college's astronomical observatory. While still an assistant, she also became acting head of astronomy at Amherst College, and the only women on the Amherst College faculty. In summers, she performed astronomical research at the Maria Mitchell Observatory in Nantucket. She was president of the American Association of Variable Star Observers for the 1947–1948 term. Williams retired from Smith in 1953. In 1959, she joined the National Science Foundation as Assistant Program Director for Astronomy.

Later life and service While still at Smith, Williams became active in Quaker efforts at war relief in Europe, through the American Friends Service Committee. In her retirement, she was active in the organization of the Washington, DC meeting of the Society of Friends. She also headed a retirement home and returned to Guilford to work as a dormitory resident and direct the student union. She died on December 28, 1983.

Recognition Williams was elected as a Fellow of the American Association for the Advancement of Science in 1932.

Worked examples

Example 1 — a first encounter with Marjorie Williams (astronomer)

Start with the simplest possible case. Write down what Marjorie Williams (astronomer) 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 Marjorie Williams (astronomer) 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 Marjorie Williams (astronomer) 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 Marjorie Williams (astronomer)

In research: Marjorie Williams (astronomer) 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 Marjorie Williams (astronomer) 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: Marjorie Williams (astronomer) is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1900 births, 1983 deaths, 20th-century American women, so understanding it makes those chapters shorter.
In everyday life: Look for Marjorie Williams (astronomer) 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.
